Osteoarticular allografts represent a reconstructive option after bone tumor resection around the knee in growing children. The major advantage is the chance to preserve the growth plate of the remaining bone, but the disadvantage is the high failure rate eventually requiring definitive prosthetic replacement at skeletal maturity. We retrospectively reviewed 22 patients who underwent osteoarticular allograft reconstructions of the distal femur (16) or proximal tibia (6). There were 12 females and 10 males with an average age at surgery of 11 years (7-15). The diagnosis was osteosarcoma in 19 cases and Ewing sarcoma in 3. All patients underwent pre- and post-operative chemotherapy. At an average follow-up of 103 months (12-167), 18 patients (82%) were alive and 4 had died (18%). We observed 10 allograft failures requiring prosthetic replacement, 6 in distal femur and 4 in proximal tibia reconstructions. At last follow-up 8 allografts (36%) were still in place. Overall allograft survival was 79.6% at five and 45.8% at ten years. In distal femur, allograft survival was 86.2% at five and 59.1% at ten years. In proximal tibia, allograft survival was 62.5% at 5 years and 31.2% at 67 months. Average limb shortening was 3 cm (0- 5) in 8 patients with the allograft still in situ and 2 cm (0-4) in 10 patients after prosthetic replacement. Average MSTS functional score of the whole series was 25 (83.7%). The MSTS score of patients after revision with prosthetic replacement was 24 (80%) while patients who still had the allograft retained had an average MSTS scores of 26.8 (89.3%). In conclusion, osteoarticular allograft reconstruction of the knee after bone tumor resection in pediatric age can be considered a temporary solution with the aim to limit limb length discrepancy before definitive prosthetic replacement after skeletal maturity.

Fulltext A comparison between subvastus and midvastus approaches for staged bilateral total knee arthroplasty:a prospective, randomised study

Masjudin T, Kamari Zh

Malays Orthop J, 2012 Nov;6(3):31-6.
PMID: 25279053 DOI: 10.5704/MOJ.1207.0018

This prospective randomised study was undertaken to compare surgical parameters as well as clinical and radiological outcomes of subvastus (SV) to midvastus (MV) approaches in staged bilateral total knee arthroplasty (TKA). Twenty-three patients, aged 55-76 years, who underwent staged bilateral TKAs, were followed up for 6 months. The SV approach was used on one knee and MV approach on the other. We found similar lateral retinacular release rates and patellar resurfacing rates between the two approaches .The SV approached knees had a more significant blood loss and increased operative time compared to the MV approached knees but they achieved significantly earlier active straightleg raises (SLR) postoperatively (p<0.05 for all). The average postoperative pain, flexion, and Knee Society scores were comparable for both approaches. TKA via SV vs. MV approaches provides comparable satisfactory short-term clinical and radiological outcomes, even though there was slightly more difficulty, more blood loss and longer operative times with the SV approach.

PMID: 25279034 MyJurnal DOI: 10.5704/MOJ.1111.005

Tuberculosis (TB), once a disease confined to undeveloped or developing nations is currently in resurgence due to pandemic human immunodeficiency virus infection and immigration from endemic areas. TB is also known as the 'great mimicker'. Extra-pulmonary tuberculosis affecting the knee is rare in all forms of TB (0.1-0.3%). Here, we report a case of isolated highly erosive TB knee in a previously fit Burmese migrant worker. He presented with after a history of fall into a drain. The patient also reported pain and swelling over his left knee for the previous three years. He had been treated for a bacterial infection of the knee in another hospital but defaulted due to financial constraints. Arthrotomy of the knee was performed including washout. Diagnosis of TB of the knee was made based on the synovial fluid and tissue culture. Treatment with antituberculosis drugs was then initiated.

Fulltext "'Doc' do I need an anterior cruciate ligament reconstruction? What happens if I do not reconstruct the cruciate ligament?"

Dhillon KS

Malays Orthop J, 2014 Nov;8(3):42-7.
PMID: 26401236 DOI: 10.5704/MOJ.1411.010

We are all aware that there has been a dramatic increase in the number of anterior cruciate ligament (ACL) reconstructions that are carried out here in Malaysia as well as around the world. The numbers of ACL injuries have undoubtedly increased over the years with greater participation of young adults in sporting activities. However it is not certain whether the increase in the numbers of reconstructions can be accounted for by the increasing numbers of ACL injuries. Without doubt commercial interests as well the influence of the biomedical companies have a role to play. In the past the rationale for surgical treatment of an ACL tear was that the ACL is vital for knee function and that in the long term ACL deficiency will lead to more injuries of the meniscus and more degeneration of the joint. This belief was prevalent because the natural history of an ACL deficient knee and the ultimate outcome of reconstruction of the ACL were both not known. However in recent years a substantial amount of research has been published, which has elucidated the natural history of ACL deficient knees as well as the long term outcome of reconstruction of the ACL.

Veerapen K, Asokan RN, Rathakrishnan V

APLAR Journal of Rheumatology, 2004;7(2):97-107.
DOI: 10.1111/j.1479-8077.2004.00069.x

Aims: To create a clinical and radiological profile of patients with symptomatic osteoarthritis of the knee in Malaysia.
Methods: One hundred consecutive patients presenting with symptomatic knee osteoarthritis at a private rheumatology clinic were profiled for demographic and clinical features. Anteroposterior weight-bearing, skyline and lateral knee X-rays were taken. Statistical Package for Social Sciences was used for data analysis.
Results: Women predominated (93%). Fifty-eight percent of the patients reported bilateral knee pain. Difficulty in walking, climbing and squatting was high (85%, 97% and 93% respectively). Patients with knee pain had a higher BMI than controls. Radiological abnormality, related to osteoarthritis was present in 97%. Osteophytes were generally tricompartmental while joint space narrowing was less evident in the lateral tibiofemoral joint than in the medial tibiofemoral joint and the patellofemoral joint. Almost half (49%) the patients manifested radiological varus deformity The severity of radiological abnormality increased with age. Although patients with unilateral pain had milder radiological abnormality, it tended to be bilateral. Clinically detectable hip abnormality and nodal osteoarthritis were uncommon, as was radiological chondrocalcinosis.
Conclusions: Patients presenting with symptomatic knee osteoarthritis to a rheumatology service had a high degree of disability, radiological abnormality and varus deformity. Radiological abnormalities were essentially bilateral and tricompartmental. © Asia Pacific League of Associations for Rheumatology.

Antony-Leo AP, Arun-Maiya G, Mohan-Kumar M, Vijayaraghavan PV

Malays Orthop J, 2019 Jul;13(2):20-27.
PMID: 31467647 DOI: 10.5704/MOJ.1907.004

Introduction: The key important factor influencing the outcomes following rehabilitation is the surgical approach involved in Total Knee Replacement (TKR). Most studies have analysed the functional outcome in comparing the approaches on surgical perspective rather on post-operative therapeutic interventions. The current study was to analyse the effects of structured TKR rehabilitation programme on the quality of life and joint specific outcomes between two different surgical approaches. Materials and Methods: In this double-blind randomised controlled trial, participants were randomly allocated to one of two groups: Group 1- those who underwent medial parapatellar approach and Group 2- those who underwent mid-vastus approach. Both groups received three-phase structured rehabilitation protocol for 12 weeks. The outcome measures of SF-36, knee mobility, isometric knee musculature strength and six-minute walk distance were measured at baseline, on discharge and at review after three months. Results: The quality of life and joint specific outcome scores were better in mid-vastus approach than the popular medial parapatellar approach. The outcomes of knee flexion mobility (p=0.04), knee extension mobility (p=0.03), isometric muscle strength of quadriceps (p=0.001), isometric muscle strength of hamstrings (p=0.03), six-minute walk distance (p=0.001) and Physical Cumulative Scores (PCS) (p=0.03) were found to exhibit significant improvements at three months follow up. Conclusion: The mid-vastus approach was found to exhibit better improvements following structured rehabilitation care, in physical summary scores of quality of life and joint specific outcomes than medial parapatellar approach.

Periprosthetic Fractures after Total Knee Arthroplasty: the Influence of Pre-Operative Mechanical Factors versus Intraoperative Factors

Zainul-Abidin S, Lim B, Bin-Abd-Razak HR, Gatot C, Allen JC, Koh J, et al.

Malays Orthop J, 2019 Jul;13(2):28-34.
PMID: 31467648 DOI: 10.5704/MOJ.1907.005

Introduction: Periprosthetic fractures are a devastating complication following total knee arthroplasty. Little is known about the effect of mechanical factors on the incidence of periprosthetic fractures. The aim of this study was to examine the correlation between pre-operative mechanical factors, like side of surgery, coronal alignment and pre-operative range of motion and intra-operative factors, and the incidence of a periprosthetic fracture, following primary total knee arthroplasty (TKA). Materials and Methods: Forty-two patients with periprosthetic fractures (PPF) after primary TKA were identified from our hospital arthroplasty registry. These patients were matched two-to-one for gender and age at primary knee arthroplasty to 84 patients without PPF. The incidence of periprosthetic fracture with regards to laterality, coronal alignment and pre-operative range of motion was analysed. Intra-operative factors like implant type, patellar resurfacing and notching were also analysed using logistic regression. Results: Coronal alignment, pre-operative range of motion and patella resurfacing were not significant predictors of periprosthetic fractures. Anterior femoral notching was found to be significantly higher in the fracture group with an odds ratio of 17. Left sided surgery was also significantly higher in the periprosthetic fracture group. Conclusion: Periprosthetic fractures are 17 times more likely to occur in a knee with anterior femoral notching. Preoperative factors like coronal alignment and poor preoperative range of motion do not seem to increase the risk of periprosthetic fractures after TKA.

Fulltext The effects of foot position on lower extremity kinematics during single leg squat among adolescent male athletes

Mohd Azhar N, Affandi NF, Mail MSZ, Shaharudin S

J Taibah Univ Med Sci, 2019 Aug;14(4):343-349.
PMID: 31488966 DOI: 10.1016/j.jtumed.2019.06.007

Objectives: The purpose of this study was to investigate the effect of transverse plane foot position on lower limb kinematics during a single leg squat.
Methods: This was a cross-sectional study conducted among highly-trained male athletes. Only participants who showed normal knee valgus during a drop landing screening test were recruited. Twelve junior athletes performed single leg squats while maintaining a knee flexion angle of 60°. The squats were executed in three foot positions: neutral (0°), adduction (-10°), and abduction (+10°). Three-dimensional motion analysis was used to capture the lower extremity kinematics of the participants' preferred limb. The hip and knee kinematics in the sagittal, frontal, and transverse planes during squatting were compared across the three foot positions using one-way ANOVA.
Results: The participants showed a normal range of dynamic knee valgus (5.3°±1.6). No statistically significant differences were observed in hip flexion (p = 0.322), adduction (p = 0.834), or internal rotation (p = 0.967) across different foot positions. Similarly, no statistically significant differences were observed in knee flexion (p = 0.489), adduction (p = 0.822), or internal rotation (p = 0.971) across different foot positions.
Conclusion: Small changes in transverse plane foot position do not affect lower extremity kinematics during single leg squat in highly trained adolescent males with normal dynamic knee valgus. Our findings may provide guidance on safer techniques for landing, pivoting, and cutting during training and game situations.

Usual Presentation Has Odds: Unilateral Tibial Hemimelia in One of Dizygotic Twins

Al-Chalabi MMM, Wan Sulaiman WA

Cureus, 2021 Jan 21;13(1):e12834.
PMID: 33633877 DOI: 10.7759/cureus.12834

Tibial hemimelia is a relatively rare congenital tibial longitudinal deficiency (approximately 1 per 1 million live births), unilateral or bilateral, with a relatively intact fibula. Hemimelia results from a disruption of the lower limb developmental field during embryogenesis due to slow or even abort of chondrification process, which results in leg length discrepancy. Affected leg commonly appears short and deformed with knee, ankle, and foot involvement. It may present with a variety of associated anomalies. Surgical treatment varies according to the type and degree of deformity, and reconstructive interventions are still limited. Reported cases of tibial hemimelia are very infrequent, especially tibial hemimelia in twins. Usually, the cases were in single embryo or less frequently in one of the monozygotic twins, but no reported cases regarding tibial hemimelia in one of the dizygotic twins as this article reports.

MyJurnal

Assessing the repeat rate is crucial to reduce unnecessary dose to the patient by identifying the major cause for repeating the x-rays exposure to the patient and apply corrective measures. To analyse the repeat rate of routine lower limb projections in direct digital radiography (DR) from general radiology department of Pantai Klang Hospital. 26 months retrospective repeated radiograph was acquired from Picture Archiving and Communication System (PACS) at Hospital Pantai Klang. The retrieved radiographs were grouped based on the reason for the i radiographs being rejected which are incorrect positioning, incorrect collimation, patient movement, incorrect exposure factors, artefact, and other reasons. Total repeated radiographs retrieved for basic lower limbs projections were 13616. Knee was the highest repeted examination and the lowest repeat rate was tibia fibula. (repeat rate: knee = 1.04%, tibia fibula = 0.57%). incorrect positioning is the major causes for repeat exposure for all examinations type, followed by incorrect collimation, other categories, centring ray error, incorrect exposure factors and artifact.

Post-operative complications are well known to impair the functional outcomes of total knee arthroplasty (TKA). Patella subluxations post-TKA is a grim complication rendering patients disable post-surgery. Howbeit, medial patella subluxation is a rarely recorded incident altogether. This case report describes a patient post successful TKA two years ago, who was incidentally diagnosed with a medial patellofemoral subluxation during a recent routine yearly follow up. This gentleman, however, had no complaints and the only evident clinical sign was anterior knee skin puckering. A radiograph of the knee confirmed our clinical suspicion of medial patella subluxation. The patient’s symptoms, his expectations, radiological findings, what went wrong during surgery and management of this rare entity were analysed. This rarely reported entity requires a high degree of suspicion especially if the patient complains of instability and peculiar anterior knee pain. Diagnosis is customarily clinical and revision surgery is almost invariably necessary.

MyJurnal

Tuberculosis (TB) is an ancient disease dated back from ancient Greece time. Once rare in developed countries, now it has re-emerged due to immigration and secondary immunodeficiency. A 27-year-old lady had left knee pain for the past 4 years, went for knee diagnostic arthroscopy procedure, and diagnosed as pigmented villonodular synovitis (PVNS) of the left knee. Despite regular analgesics and physiotherapy, patient symptoms worsen. Two years after the initial treatment, the patient went for a further workout and diagnosed as knee tuberculosis, commenced on anti-TB treatment, the patient still left complicated with a stiff knee and fixed flexion deformity. Identification of knee tuberculosis during the initial phase is crucial as late diagnosis and treatment will leave the patient with debilitating complications.

IIUM Medical Journal Malaysia, 2020;19(1):31-36.
MyJurnal

Introduction: Hamstring tendon (HT) and bone patellar tendon bone (BPTB) are the commonly used
autograft in an anterior cruciate ligament reconstruction surgery. The BPTB is said to have more incidence of
anterior knee pain compared to HT. The study aimed to compare the severity of knee pain during Islamic
prayer kneeling. Methods: A cross sectional cohort analysis of patients undergoing ACL reconstruction surgery
using BPTB with HT autografts was conducted to determine differences in postoperative pain while kneeling
and ability to pray in normal position. Kneeling during prayer and the ability to sit while performing prayer
were assessed at 3rd, 4th, 5th and 6th month. Results: There were no significant differences in mean pain score
while kneeling at 3rd, 4th, 5th and 6th month. The mean difference of patient’s ability to perform normal
prayers for BPTB (3.56+1.16) and HT (3.30+1.05) was found insignificant. The average number of patients in
both groups was able to pray between 3 to 4 months post operatively as full range of motion of knee is
allowed within this period. Total 49 patients (BPTB 23, HT 26) out of 60 were able to pray normally within 4
months post-operation. Mostly delayed due to anterior knee pain. Conclusion: There is no different in term of
knee pain during kneeling while performing Islamic prayer between those who had their ACL reconstructed
either using BPTB or HT autograft.

MyJurnal

Critical size defects (CSD) in the long bones of New Zealand White rabbits (Oryctolagus cuniculus) have been used for years as an experimental model for investigation of the effectiveness of a new bone substitute material. There are varieties of protocols available in the literature. This technical note attempts to present an alternative surgical technique of a CSD in the New Zealand white rabbit tibia. Methods: Thirty-nine New Zealand White rabbits were used in this study. A CSD of approximately 4.5 mm (width) X 9.0 mm (length) was surgically drilled at the proximal tibial metaphysis, approximately 1 cm from the knee joint. The surrounding of soft tissue was repositioned and sutured layer by layer with bioabsorbable surgical suture. Two x-rays of anteroposterior and lateral were taken before assessed under computed tomography scan at 6, 12 and 24 weeks. Results: This alternative method created CSD with less bleeding from the muscle observed. No mortality or other surgical complications observed within 6 weeks, 12 weeks and 24 weeks following surgery. Conclusion: A simple and safe method for performing CSD was demonstrated and recommended as an alternative approach for surgery on New Zealand White rabbits.

Leelasestaporn C, Thuwapitchayanant M, Sirithanapipat P, Sa-Ngasoongsong P, Ruengsilsuwit P

Malays Orthop J, 2021 Mar;15(1):79-84.
PMID: 33880152 DOI: 10.5704/MOJ.2103.012

Introduction: The aim of this study was to evaluate the reliability of the femoral component rotation on intra-operative data recorded in a computer-assisted navigation system (CAN-FRA) compared with the post-operative femoral component rotation observed on computed tomography (CT-FRA).
Material and method: Computer-assisted total knee arthroplasty (TKA) or primary osteoarthritis of the knee was performed in 51 knees in 36 patients with a mean age of 69.51 years. All procedures were performed by a single surgeon using the same implant design. The intraclass correlation coefficient (ICC) was used to compare the intra-operative CAN-FRA with the post-operative CT-FRA. The angle between the anatomical epicondylar axis and the posterior condylar axis of the implant (CT-FRA) was measured at two separate timepoints by three observers who were blinded to the intra-operative CAN-FRA. Internal rotation was defined as rotation in the negative direction, while external rotation was defined as positive.
Results: The mean intra-operative CAN-FRA was 0.1° ± 2.8° (range -5.0° to 5.5°). The mean post-operative CT-FRA was -1.3° ± 2.1° (range -4.6° to 4.4°). The mean difference between the CAN-FRA and the CT-FRA was -1.3° ± 2.2° (range -7.9° to 2.4°). The respective ICC values for the three observers were 0.92, 0.94, and 0.93, while the respective intra-observer coefficients were 0.91, 0.85, and 0.90. The ICC for the intra-operative CAN-FRA versus the post-operative CT-FRA was 0.71.
Conclusion: This study shows that using a computer-assisted navigation system in TKA achieves reliable results and helps to achieve optimal positioning of the femoral component and rotation alignment correction.

Fulltext Single-Bundle Versus Double-Bundle Arthroscopic Anterior Cruciate Ligament Reconstruction: Comparison of Long-Term Functional Outcomes

Anandan V, Goh TC, Zamri KS

Cureus, 2020 Dec 23;12(12):e12243.
PMID: 33500862 DOI: 10.7759/cureus.12243

Objective To compare long-term functional results of ACL reconstruction with a single bundle (SB) and double bundle (DB). Methods Sixty patients who underwent ACL reconstructions from January 2007 to December 2008 were retrospectively evaluated (30 SB and 30 DB ACL reconstructions). Clinical and functional outcomes were measured pre- and postoperatively in terms of anterior drawer test, Lachman's test, pivot shift test, KT1000 side-to-side difference, range of motion, International Knee Documentation Committee Scoring, Lysholm knee scoring scale (LKS), and Tegner activity level scale. The period of follow-up was 10 years. Results Clinical outcome measured showed that anterior drawer test result were equally normal for both groups (93.3%; p > 0.995); however, the Lachman test was 76.7% in the DB group and 56.7% in the SB group (p > 0.100), the pivot shift was 83% in the DB group and 50% in the SB group (p < 0.001), and KT1000 was 76.7% in the DB group and 56.7% in the SB group (p > 0.100). Regarding the functional outcome, it favored the DB group of patients, with the LKS being statistically significant (p < 0.007) and the Tegner activity level scale p-value being <0.001 Conclusions DB ACL reconstruction produces better rotational stability and gives superior functional outcome in terms of return to pre-injury activity level in comparison to SB reconstruction. DB ACL reconstruction using hamstring tendon autograft produces better functional results at 10 years follow-up.

Muhammad Hanif Ramlee

Malaysian Journal of Medicine and Health Sciences, 2020;16(3):262-271.
MyJurnal

Most orthopaedic cases that involved with bone fracture are normally treated with medical implants. To be noticed that some precautions in terms of biomechanical and biomaterial properties are necessary for a successful post-sur- gery process. The biomechanical evaluation of implants could be carried out using computing and engineering technologies. However, in the computer simulation, some assumptions are needed as the limitations on computer resources and data input. This review focuses on the current method of developing the finite element model for patients with specific values of material properties for lower limb part such as hip, knee and ankle joint. Previous literature was reviewed from which keywords and search engines were identified. In this review, inclusion and exclusion criteria were used to limit the literature search. We reviewed the state-of-the-art in this area and provide recommendations for future research. In conclusion, the previous published reports illustrated different methods to develop numerical models.

Malays Orthop J, 2008;2(2):40-42.
MyJurnal

In comminuted patellar fractures, a combination of cerclage wiring and tension band fixation is said to provide good mechanical stability. This is a retrospective review of four patients treated with this method. All fractures described herein were classified as 45-C3 (based on Orthopaedic Trauma Association classification) and were fixed with a 1.25mm cerclage wire and tension band wire proximally looped through the quadriceps tendon and distally through the patellar ligament in a figure-of-eight configuration. The average follow-up period was 10 months. The Activity of Daily Living Scale (ADLS) of the Knee Outcome Survey was used to assess symptoms and functional capability of the knee. In all the cases, fracture union was achieved at an average of 11 weeks. The average ADLS score was good (92.5 %). Full range of knee motion was achieved by end of the third postoperative month. None of the patients had complications, such as infection and implant failure.

Fulltext Treament of tibial plateau Schatzker type VI fractures with the Ilizarov technique using ring external fixators across the knee: a retrospective review

Ranatunga, I.R., Thirumal, M.

Malays Orthop J, 2010;4(2):34-39.
MyJurnal

This is a retrospective review of 18 patients with tibial plateau fractures Schatzker type VI. These cases were performed in our medical centre from January 2003 to December 2004. The Ilizarov technique (Russian technique) using the ring external fixator was the technique performed. Articular reconstruction and joint alignment were achieved with traction and olive wires with washers. One case required percutaneous elevation of the articular surface and bone grafting through a cortical window. Average clinical union was achieved within 4 months of trauma. Mean final knee flexion was 85Â°, which is compatible with walking. All patients successfully returned to their previous occupations. In conclusion, the Ilizarov technique has been shown to be a good option and a viable tool in the management of these complex and unstable injuries.
