    Symptomatic slow-acting drugs for osteoarthritis (SYSADOAs) are recommended for the medium- to long-term management of knee osteoarthritis (OA) due to their abilities to control pain, improve function and delay joint structural changes. Among SYSADOAs, evidence is greatest for the patented crystalline glucosamine sulfate (pCGS) formulation (Mylan). Glucosamine is widely available as glucosamine sulfate (GS) and glucosamine hydrochloride (GH) preparations that vary substantially in molecular form, pharmaceutical formulation and dose regimen. Only pCGS is given as a highly bioavailable once-daily dose (1500 mg), which consistently delivers the plasma levels of around 10 μmol/L required to inhibit interleukin-1-induced expression of genes involved in the pathophysiology of joint inflammation and tissue destruction. Careful consideration of the evidence base reveals that only pCGS reliably provides a moderate effect size on pain that is higher than paracetamol and equivalent to non-steroidal anti-inflammatory drugs (NSAIDs), while non-crystalline GS and GH fail to reach statistical significance for pain reduction. Chronic administration of pCGS has disease-modifying effects, with a reduction in need for total joint replacement lasting for 5 years after treatment cessation. Pharmacoeconomic studies of pCGS demonstrate long-term reduction in additional pain analgesia and NSAIDs, with a 50% reduction in costs of other OA medication and healthcare consultations. Consequently, pCGS is the logical choice, with demonstrated medium-term control of pain and lasting impact on disease progression. Physician and patient education on the differentiation of pCGS from other glucosamine formulations will help to improve treatment selection, increase treatment adherence, and optimize clinical benefit in OA.

    Osteoarthritis (OA) affects millions of people worldwide with its irreversible destruction of articular cartilage. Recently, the potential of using chondrogenic differentiated multipotent mesenchymal stromal cells (cMSCs) for OA treatment is being assessed. Preliminary clinical studies have been encouraging. However current studies have also demonstrated that cMSCs are not biochemically and biomechanically identical to native articular chondrocytes (ACs). Thus, there is an urgent need for the implementation of proteomic applications as proteomics involve protein identification, relative quantification of proteins and studies of post-translational modification which reveal novel regulating processes of complex mechanisms such as in chondrogenesis. A comprehensive understanding of chondrogenesis is essential for the establishment of an effective cMSC model to regenerate cartilage. In this article, we will review current proteomic studies on chondrogenesis, focusing on recent findings and the proteomic approaches utilised.

    Pain is an unpleasant sensation that can cause physical and psychological problems for the patient. Despite the pharmacological intervention for reducing pain, it remains as an issue after surgery. Music therapy as non-pharmacological intervention can effect post-operative pain and patients’ requirement of analgesics. The purpose of this study was to determine effect of music therapy on pain after elective total knee replacement (TKR) surgery. This study compared analgesics consumption by patients post-operatively for five days. A Quasi-experimental design with convenience sample of patient with a mean of 64.35 (49-76) who underwent TKR in UKM Medical Centre from May to December 2012 was used. Forty patients were randomly assigned in one of the two groups using a sealed-envelope technique. The experimental group listened to music for five days post-operatively and were on analgesics and control group were treated with pharmacological intervention only. Pain was measured by McGill Pain Questionnaire-Short Form (MPQ-SF) for patient on bed rest on day one, day three and day five post-operatively. Statistical (Mann- Whitney) findings between groups showed the experimental group significantly had less pain on day one and day five rather than the control group at 0.05 level using Pain Rating Intensity (PRI), Visual Analogue Scale (VAS) and Present Pain Intensity (PPI). Statistical (Friedman) tests within group showed that the patient had significantly decreased pain over time at level 0.05 using PRI, VAS and PPI. Statistical (Mann- Whitney) tests revealed that there was no significant difference when using analgesics between the two groups in five days post-operatively at milligram but comparing median showed experimental group used less analgesic than control group. Music therapy is simple, available, save and cheap effective intervention for pain management post-operatively. Pain management is one of the key roles of nursing and nurses can use music therapy as a simple intervention to reduce pain.

    Treatment effectiveness depends on the knowledge, attitude, and practice (KAP) of osteoarthritis (OA) patients to- wards their assigned treatment. This study aimed to explore the KAP towards non-surgical intervention among OA patients. A methodological framework proposed by Arksey and O’Malley (2005) was implemented. An electronic database search of English-language academic articles was conducted using PubMed and ScienceDirect databases encompassing 1998 to 2018 period of time, resulting in a total of 26 studies. OA patients were knowledgeable about the disease and exercise management. However, they were lack of knowledge on drug therapy and complementary strategies. The attitude towards non-surgical interventions was ambivalence. Lastly, the practice section mainly fo- cused on patients’ compliance and behaviour towards different conservative managements, namely physiotherapy, medications, and complementary and alternative medicines (CAMs) which influenced by both knowledge level and attitudes. In conclusion, a higher knowledge level and positive attitude will result in good practice.

  5. Hyaluronic acid with or without bone marrow derived-mesenchymal stem cells improves osteoarthritic knee changes in rat model: a preliminary report
    Suhaeb AM, Naveen S, Mansor A, Kamarul T
    Indian J Exp Biol, 2012 Jun;50(6):383-90.
    PMID: 22734248
    Despite being a complex degenerative joint disease, studies on osteoarthritis (OA) suggest that its progression can be reduced by the use of hyaluronic acid (HA) or mesenchymal stem cells (MSC). The present study thus aims to examine the effects of MSC, HA and the combination of HA-MSC in treating OA in rat model. The histological observations using O'Driscoll score indicate that it is the use of HA and MSC independently and not their combination that delays the progression of OA. In conclusion, the preliminary study suggest that the use of either HA or MSCs effectively reduces OA progression better than their combined use.

  6. Direct and indirect costs of osteoarthritis in Singapore: a comparative study among multiethnic Asian patients with osteoarthritis
    Xie F, Thumboo J, Fong KY, Lo NN, Yeo SJ, Yang KY, et al.
    J Rheumatol, 2007 Jan;34(1):165-71.
    PMID: 17216684
    OBJECTIVE:
    To estimate and compare the direct and indirect costs of osteoarthritis (OA) in multiethnic Asian patients with OA in Singapore.

    METHODS:
    The study was a retrospective and cross-sectional design. Patients were stratified according to ethnicity and presence or absence of joint surgery. Direct costs were estimated from both a societal and a patient perspective using the Singapore General Hospital database; indirect costs were estimated using the human capital approach. All costs were expressed as mean costs per patient per annum in 2003 Singapore dollars.

    RESULTS:
    A total of 1179 patients (83.6% Chinese, 7.2% Malay, 3.5% Indian, 5.7% others) were included in estimating direct costs, of which 513 (43.5%) had total knee replacement (TKR) and 92 (7.8%) total hip replacement (THR), while 105 patients (71.4% Chinese, 14.3% Malay, 14.3% Indian) were included in estimating indirect costs. Direct costs to patients ranged from 1460 dollars to 7477 dollars for Chinese, 1362 dollars-7211 dollars for Malays, 1688 dollars-6226 dollars for Indians, and 1437 dollars-12,140 dollars for other ethnic patients; direct costs to society ranged from 3351 dollars to 15,799 dollars for Chinese, 2939 dollars-15,436 dollars for Malays, 3150 dollars-10,990 dollars for Indians, and 2597 dollars-17,879 dollars for other ethnic patients. In contrast, the indirect costs ranged from 1215 dollars to 3834 dollars for Chinese, 1138 dollars-6116 dollars for Malays, and 1371 dollars-5292 dollars for Indians. However, most ethnic variations were not statistically significant.

    CONCLUSION:
    The economic burden of OA to society and patients increased by 3-fold or more in the patients with TKR/THR compared to those without. The ethnic differences in health resources consumed were more apparent when the disease progressed.

    Malays Orthop J, 2014 Jul;8(2):59-62.
    PMID: 25279097 MyJurnal DOI: 10.5704/MOJ.1407.007
    Shoulder impingement syndrome and acromioclavicular joint osteoarthritis often occur simultaneously and easily missed. Kay et al. reported excellent results with combined arthroscopic subacromial decompression and resection of the distal end of the clavicle in patients with both disorders(1). Arthroscopic treatment of these disorders produces more favourable results than open procedures. We report two patients who were not responding to conservative management and were treated with direct arthroscopic distal clavicle excision and subacromial decompression in single setting. Both patients gained good postoperative outcome in terms of pain score, function and strength improvement assessed objectively with visual analogue score (VAS) and University of California Los Angeles Score (UCLA).

    PMID: 25861373 DOI: 10.1155/2015/942378
    Objective. To determine the clinical effects of Thai herbal compress. Methods. International and Thai databases were searched from inception through September 2014. Comparative clinical studies investigating herbal compress for any indications were included. Outcomes of interest included level of pain, difficulties in performing activities, and time from delivery to milk secretion. Mean changes of the outcomes from baseline were compared between herbal compress and comparators by calculating mean difference. Results. A total of 13 studies which involved 778 patients were selected from 369 articles identified. The overall effects of Thai herbal compress on reducing osteoarthritis (OA) and muscle pain were not different from those of nonsteroidal anti-inflammatory drugs, knee exercise, and hot compress. However, the reduction of OA pain in the herbal compress group tended to be higher than that of any comparators (weighted mean difference 0.419; 95% CI -0.004, 0.842) with moderate heterogeneity (I (2) = 58.3%, P = 0.048). When compared with usual care, herbal compress provided significantly less time from delivery to milk secretion in postpartum mothers (mean difference -394.425 minutes; 95% CI -620.084, -168.766). Conclusion. Thai herbal compress may be considered as an alternative for osteoarthritis and muscle pain and could also be used as a treatment of choice to induce lactation.

  9. Fulltext Osteoarthritis and falls in the older person
    Ng CT, Tan MP
    Age Ageing, 2013 Sep;42(5):561-6.
    PMID: 23864423 DOI: 10.1093/ageing/aft070
    Osteoarthritis and falls are common conditions affecting older individuals which are associated with disability and escalating health expenditure. It has been widely assumed that osteoarthritis is an established risk factor for falls in older people. The relationship between osteoarthritis and falls has, quite surprisingly, not been adequately elucidated, and published reports have been conflicting. Our review of the existing literature has found limited evidence supporting the current assumption that the presence of osteoarthritis is associated with increased risk of falls with suggestions that osteoarthritis may actually be protective against falls related fractures. In addition, joint arthroplasty appears to increase the risk of falls in individuals with osteoarthritis.

  10. Biomechanical and functional efficacy of knee sleeves: A literature review
    Mohd Sharif NA, Goh SL, Usman J, Wan Safwani WKZ
    Phys Ther Sport, 2017 Nov;28:44-52.
    PMID: 28673759 DOI: 10.1016/j.ptsp.2017.05.001
    BACKGROUND: Knee sleeves are widely used for the symptomatic relief and subjective improvements of knee problems. To date, however, their biomechanical effects have not been well understood.

    OBJECTIVE: To determine whether knee sleeves can significantly improve the biomechanical variables for knee problems.

    METHOD: Systematic literature search was conducted on four online databases - PubMed, Web of Science, ScienceDirect and Springer Link - to find peer-reviewed and relevant scientific papers on knee sleeves published from January 2005 to January 2015. Study quality was assessed using the Structured Effectiveness Quality Evaluation Scale (SEQES).

    RESULTS: Twenty studies on knee sleeves usage identified from the search were included in the review because of their heterogeneous scope of coverage. Twelve studies found significant improvement in gait parameters (3) and functional parameters (9), while eight studies did not find any significant effects of knee sleeves usage.

    CONCLUSION: Most improvements were observed in: proprioception for healthy knees, gait and balance for osteoarthritic knees, and functional improvement of injured knees. This review suggests that knee sleeves can effect functional improvements to knee problems. However, further work is needed to confirm this hypothesis, due to the lack of homogeneity and rigor of existing studies.

  11. Fulltext Randomized controlled trial comparing efficacy of conventional and new single larger dose of intra-articular viscosupplementation in management of knee osteoarthritis
    Suppan VKL, Wei CY, Siong TC, Mei TM, Chern WB, Nanta Kumar VK, et al.
    J Orthop Surg (Hong Kong), 2017 9 28;25(3):2309499017731627.
    PMID: 28946838 DOI: 10.1177/2309499017731627
    BACKGROUND: Intra-articular hyaluronic acid (HA) injection is used in management of knee, hand and hip osteoarthritis. While HA injection is included in the list of evaluated therapies, its efficacy and optimum dosing still have no consensus. This study was conducted to explore the possibility of using single injection HA to increase patient convenience while maintaining the therapeutic efficacy.

    METHODS: We present a prospective, open label, non-blinded, randomized controlled trial performed in accordance with guidelines in principles of good clinical practice. Block randomization was done for patients to receive either single 5 ml GO-ON injection or the conventional three injections of 2.5 ml GO-ON at weekly interval. Baseline Western Ontario McMaster University Osteoarthritis (WOMAC) scores were evaluated and recorded. All subjects were re-evaluated at 3 months and the WOMAC score recorded again as primary end points. Data analyses were performed with IBM SPSS Statistics for Windows software (version 21.0, IBM Corp, Armonk, New York, USA).

    RESULTS: In the cohort of 127 patients, 33 were males and 94 females. The mean age was 59.1 years (standard deviation (SD) = 7.25) in single injection arm and 60.1 years (SD = 7.72) in triple injection arm. The two groups were recorded to have no significant difference in age ( p = 0.46) and Kellgren-Lawrence radiological grade ( p = 0.694). There was significant increase in the WOMAC scores from the baseline (pre-injection) to that recorded 3 months after injection ( p < 0.001) in patients of both groups. However, there was no statistically significant difference noticed in this clinical improvement between the two arms ( p = 0.889).

    CONCLUSION: The study shows single 5 ml dose regime comparing well with conventional three doses of 2.5 ml of intra-articular GO-ON HA injected at weekly intervals and confirms good efficacy, tolerability and safety of single larger dose of GO-ON knee intra-articular injection.

    PMID: 29283019 DOI: 10.1177/0954411917750409
    This study aims to investigate the effects of varying toe angles at different platform settings on Overall Stability Index of postural stability and fall risk using Biodex Balance System in healthy participants and medial knee osteoarthritis patients. Biodex Balance System was employed to measure postural stability and fall risk at different foot progression angles (ranging from -20° to 40°, with 10° increments) on 20 healthy (control group) and 20 knee osteoarthritis patients (osteoarthritis group) randomly (age: 59.50 ± 7.33 years and 61.50 ± 8.63 years; body mass: 69.95 ± 9.86 kg and 70.45 ± 8.80 kg). Platform settings used were (1) static, (2) postural stability dynamic level 8 (PS8), (3) fall risk levels 12 to 8 (FR12) and (4) fall risk levels 8 to 2 (FR8). Data from the tests were analysed using three-way mixed repeated measures analysis of variance. The participant group, platform settings and toe angles all had a significant main effect on balance ( p ≤ 0.02). Platform settings had a significant interaction effect with participant group F(3, 144) = 6.97, p

  13. Fulltext Consensus recommendations for managing osteoarthritic pain with topical NSAIDs in Asia-Pacific
    Rafanan BS, Valdecañas BF, Lim BP, Malairungsakul A, Tassanawipas W, Shiyi C, et al.
    Pain Manag, 2018 Mar;8(2):115-128.
    PMID: 29251544 DOI: 10.2217/pmt-2017-0047
    Osteoarthritis prevalence is expected to increase markedly in the Asia-Pacific region due to rapid population aging. Identifying effective and safe therapeutic options to manage osteoarthritic pain is viewed as a priority. The Asia-Pacific Experts on Topical Analgesics Advisory Board developed consensus statements for use of topical NSAIDs in musculoskeletal pain. Evidence supporting these statements in osteoarthritic pain was reviewed. Best available evidence indicates that topical NSAIDs have a moderate effect on relief of osteoarthritic pain, comparable to that of oral NSAIDs but with a better risk-to-benefit ratio. International clinical practice guidelines recommend topical NSAIDs on par with or ahead of oral NSAIDs for pain management in patients with knee and hand osteoarthritis, and as the first-line choice in persons aged ≥75 years.

    Clin Interv Aging, 2017;12:2025-2032.
    PMID: 29238177 DOI: 10.2147/CIA.S149991
    The purpose of this study was to investigate the role of fear of falling (FoF) and psychological symptoms in explaining the relationship between osteoarthritis (OA) symptom severity and falls. Individuals aged ≥65 years with ≥2 falls or ≥1 injurious fall over the past 12 months were included in the falls group, while volunteers aged ≥65 years with no history of falls over 12 months were recruited as controls. The presence of lower extremity OA was determined radiologically and clinically. Severity of symptoms was assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire. FoF and psychological status were measured with the shortened version of the Falls Efficacy Scale-International and the 21-item Depression, Anxiety and Stress Scale (DASS-21), respectively. Of 389 (229 fallers, 160 non-fallers) potential participants, mean (SD) age: 73.74 (6.60) years, 141 had clinical OA and 171 had radiological OA. Fallers with both radiological OA and clinical OA had significantly higher FoF and DASS-21 scores than non-fallers. FoF was significantly positively correlated with symptom severity in fallers and non-fallers with radiological and clinical OA. Depression, anxiety, and stress scores were only significantly correlated with symptom severity among fallers but not non-fallers in both clinical and radiological OA. The relationship between mild symptoms and reduced risk of falls compared to no symptoms in those with radiological OA was attenuated by increased anxiety. The increased falls risk associated with severe symptoms compared to mild symptoms in clinical OA was attenuated by FoF. FoF may, therefore, be a potentially modifiable risk factor for OA-associated falls which could be considered in future intervention studies.

    Osteoporosis (OP) and osteoarthritis (OA) are debilitating musculoskeletal diseases of the elderly. Ficus deltoidea (FD) or mistletoe fig, a medicinal plant, was pre-clinically evaluated against OP- and OA-related bone alterations, in postmenopausal OA rat model. Thirty twelfth-week-old female rats were divided into groups (n = 6). Four groups were bilateral ovariectomized (OVX) and OA-induced by intra-articular monosodium iodoacetate (MIA) injection into the right knee joints. The Sham control and OVX-OA non-treated groups were given deionized water. The three other OVX-OA groups were orally administered daily with FD extract (200, 400 mg/kg) or diclofenac (5 mg/kg) for 4 weeks. The rats' bones and blood were evaluated for protein and mRNA expressions of osteoporosis and inflammatory indicators, and micro-CT computed tomography for bone microstructure. The non-treated OVX-OA rats developed severe OP bone loss and bone microstructural damage in the subchondral and metaphyseal regions, supported by reduced serum bone formation markers (osteocalcin, osteoprotegerin) and increased bone resorption markers (RANKL and CTX-I). The FD extract significantly (p

    Lipoma arborescens is a non-neoplastic, reactive condition due to chronic synovial inflammation and irritation, characterized by frond-like or villous proliferation of mature adipose tissue covered by hyperplastic synovium. The knee is the most commonly affected site particularly the suprapatellar pouch. We report a case of lipoma arborescens affecting the right knee of an elderly Chinese gentleman associated with bilateral knee and hand osteoarthritis. He presented with progressive worsening of right knee swelling and pain. Partial synovectomy of the right knee was performed and no lesion recurrence was noted at one year post-operation. The clinical and imaging findings, pathological features, together with differential diagnoses were discussed.

    Biotechnol Appl Biochem, 2021 Aug;68(4):726-731.
    PMID: 32621620 DOI: 10.1002/bab.1981
    The urinary C-terminal telopeptide fragment of type II collagen (uCTX-II) has been reported as the efficient blood-based biomarker for osteoarthritis, which affects knees, hands, spine, and hips. This study reports a sensing strategy with antibody-conjugated gold nanoparticles (GNP) on an interdigitated electrode (IDE) to determine uCTX-II. The GNP-antibody complex was chemically immobilized on the IDE surface through the amine linker. uCTX-II was determined by monitoring the alteration in current upon interacting the GNP-complexed antibody. This strategy was improved the detection by attracting higher uCTX-II molecules, and the detection limit falls in the range of 10-100 pM with an acceptable regression value [y = 0.6254x - 0.4073, R² = 0.9787]. The sensitivity of the detection was recognized at 10 pM. Additionally, upon increasing the uCTX-II concentration, the current changes were increased in a linear fashion. Control detection with nonimmune antibody and control protein do not increase the current level, confirming the specific detection of uCTX-II. This method of detection helps in diagnosing osteoarthritis and its follow-up treatment.

    Textitis is a new term used to refer to the degenerative-strain osteoarthritis that comes from excessive use of a smart phone. 18F-NaF is increasingly used in diagnosing skeletal pain that is not identified on radiographs. We report a case of a 26-y-old woman with left breast cancer referred for 18F-NaF PET/CT, who was complaining of right thumb and wrist pain. Findings were negative for bone secondaries. Dedicated hands views were acquired on a positron emission mammography scanner and showed focal uptake at the first carpometacarpal and second metacarpophalangeal joints. On the basis of the strong history, the findings were likely due to active arthritic changes caused by repetitive strain injury from excessive text messaging.

    PMID: 14556327
    To retrospectively study the long term results of high tibial valgus osteotomy in management of primary medial compartment osteoarthritis, with special reference to patient satisfaction and functional assessment, we conducted this study in radiologically established 50 knees of patients with primary osteoarthrosis of knee. In these patients with medial compartment disease (varus knee), medial open wedge osteotomy was performed using full thickness iliac crest grafts. These were called for follow-up after average 7.5 years and clinico-radiological assessment was done. Although many surgeons of the west do not favour this osteotomy, we found the procedure to be quite acceptable to our patients in whom the primary concerns of cost and squatting habits are well taken care of. The authors feel that this osteotomy is still relevant in the third world. Results do deteriorate with time but most patients consider the surgery satisfactory.

    Looi LM
    Histopathology, 1991 Aug;19(2):169-72.
    PMID: 1757071
    Seventeen consecutive patients with dystrophic amyloidosis are reported here (eight Chinese, three Indian, three Iban, two Malay and one Caucasian). Ten were females and seven males, with ages ranging from 12 to 80 years (mean of 48 years). Five instances of dystrophic amyloidosis occurred in areas of tissue damage in the cardiovascular system, including fibrotic cardiac valves and an atheromatous plaque. Three occurred in osteoarthritic joint tissue. Of note were three occurrences in endometriotic cyst walls, four in the fibrotic walls of epidermal cysts, one in a hernial sac and one at the edge of a skin ulcer. All deposits were congophilic and exhibited green-birefringence and permanganate-resistance. Immunohistochemistry did not reveal reactivity for AA protein or immunoglobulin lambda or kappa light-chains. AP protein was detected in 35% of cases. Our results show that, besides the usual sites of osteoarthritic joints and damaged heart valves, dystrophic amyloidosis can complicate other areas of chronic tissue damage and fibrosis such as walls of cysts and ulcers. While the pathogenesis and biochemical nature remain unresolved, immunohistochemistry indicates that neither AA nor AL proteins are present in the deposits, and suggests that a different amyloid protein is involved.
