    In an arthroscopic-MRI correlation study of acute injuries to the knee it was found that anterolateral meniscocapsular separations of the lateral aspect of the knee were missed on MRI reporting. Eighty sports-related injuries of the knee were seen by experienced orthopaedic surgeons at the University of Malaya Medical Centre and at the National Sports Centre, Malaysia from January 1996 to July 1997. Fifty of the patients were suspected to have meniscal tears that were either lateral or medial on clinical examination and they were sent for MRI. Many of these patients were tertiary referrals. Magnetic resonance imaging examinations in 27 of the 50 patients were reported as not showing any intrasubstance or obvious meniscocapsular tears, but arthroscopy performed on them revealed anterolateral meniscocapsular tears of the lateral meniscus of varying degrees in nine of these patients. In retrospect the tears could be seen on MRI, and a pattern to the tears was noted and classified as follows. Type 0, normal; type 1, torn inferior or superior meniscocapsular attachment; type 2, both meniscofemoral and meniscotibial ligaments torn but with minimal separation of meniscus and capsule by fluid or synovitis; and type 3, marked separation of meniscus and capsule by fluid (> 3 mm). Ten patients who did not undergo arthroscopy for various personal and financial reasons underwent MRI which showed type 1 and type 2 tears, and were treated conservatively. These patients were all asymptomatic after 4-6 weeks with regard to clinical signs, suggesting a lateral meniscal tear. Magnetic resonance imaging therefore does reveal minor degrees of meniscocapsular tears anterolaterally when one understands the normal anatomy in this region.

    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.

    This study evaluates the outcome of anterior cruciate ligament (ACL) reconstruction with arthroscopy using the bone–patella tendon-bone method. We performed this procedure in 24 patients with the average age of 33.1 years (range: 17-51 years ) between 2004 and 2006. Sixteen of the 24 patients were available for evaluation using the Lysholm Knee Score and International Knee Documentation Committee (IKDC) system. Based on the Lysholm score, there was a statistically significant improvement in knee function when comparing pre- and post-surgical scores (p

    Traumatic rupture of the popliteus tendon is a rare type of knee injury. Most reported cases had occurred in athletes or following high impact trauma. We report a case of a 23-year-old male with an isolated complete popliteus tendon rupture that was diagnosed arthroscopically. The patient worked as a general labourer in a sawmill. He fell at his workplace and presented with acute painful fixed flexion of the right knee. Initially he was suspected to have a meniscus tear. Diagnostic arthroscopy of the knee was carried out; and diagnosis of popliteal tendon rupture was established. The patient was subsequently managed conservatively by arthroscopic debridement. He was allowed to mobilize the knee as tolerated after the surgery. He was well with a full knee range of movement and was able to walk normally at six weeks after surgery. This article highlights the possibility of complete popliteus tendon rupture following a minor occupational injury in a previously normal knee.

    We present an unusual case, where the medial meniscus does not coincide with the embryological development of the formation of a discoid cartilage. A fairly, careful perusal of English literature since 1945 to date makes us feel that the following case merits recording. The meniscus had a normal anterior horn attached to the intercondylar area, in front of the anterior cruciate ligament. Medially, it was attached to the capsule and the condylar surface of the medial tibial plateau. The posterior horn was rounded, smooth, and floating free of any attachments. It was approximately 2 cms in length, semilunar in shape, and extended posteriorly up to the anterior margin of the medial collateral ligament. The rest of the medial tibial plateau had no other protective covering.

    BACKGROUND: This study aimed to report the outcome of patients who underwent arthroscopic rotator cuff repair (ARCR) and to determine the factors associated with return to work and activity.
    MATERIALS: Three hundred sixty-five patients who underwent ARCR were prospectively evaluated. The cohort was divided into 2 groups based on clinical results at 6 months. Group A consisted of patients who were considered to have a satisfactory outcome based on return to their previous professional or spare-time activities. Group B consisted of patients with an unsatisfactory outcome based on a lack of return to normal work or activities.
    RESULTS: Of the patients, 305 had a satisfactory outcome (group A) and 60 were categorized as having an unsatisfactory outcome (group B). On multivariate analysis, preoperative factors associated with group B included female gender and heavy manual labor. Postoperative bursitis on ultrasound at 6 months was associated with being in group B. Lack of tendon healing was not associated with group B. However, if a patient without healing had persistent pain at 6 months, the pain persisted at 9 months.
    CONCLUSION: ARCR is an effective procedure that leads to significant improvement in pain, function, and tendon healing in most cases. However, in 1 of 5 cases, patients were unable to resume normal activity at 6 months postoperatively. Persistent limitation at 6 months was associated with female gender, heavy manual workers, and the presence of postoperative persistent bursitis.

    PURPOSE: Arthroscopic-assisted stabilization surgery for acute acromioclavicular joint (ACJ) disruption shows excellent and reliable clinical outcomes. However, characteristic complications such as fracture of the clavicle and coracoid have been reported to occur during the early post-operative period. The main goal of this study was to highlight the occurrence of fractures as a late post-operative complication. The secondary goals were to describe possible fracture morphologies and treatment outcomes.

    METHOD: Patient records from a single surgery centre were searched for all patients presenting with late fracture complication following arthroscopically assisted acromioclavicular stabilization. Medical reports including the operative notes and pre- and post-operative X-rays were reviewed. A telephone interview was conducted with each patient to access the American Shoulder and Elbow Surgeons shoulder score.

    RESULTS: A total of four patients presented with late fracture complication following arthroscopic-assisted ACJ stabilization surgery. All patients were males and presented following trauma at a median duration of 19.5 months after the index surgery. Fracture morphology differed between patients; the treatment was conservative in three patients, while one patient underwent osteosynthesis.

    CONCLUSION: Traumatic peri-implant fractures can occur, even 2 years after arthroscopically assisted ACJ reconstruction. This needs to be considered when planning for surgical intervention in acute ACJ disruption, especially in a high-risk population.

    BACKGROUND: This study compares the outcomes of calcaneal fracture surgery after open reduction internal fixation and plating (ORIF) versus arthroscopic assisted percutaneous screw fixation (APSF).

    METHODS: Group I (N=12) underwent ORIF. Group II (N=15) underwent APSF. Anthropometric data, pre and post-operative stay, complications and duration off work were recorded in this retrospective case cohort study. Radiographs were analyzed for Bohler's, Gissane's angle and Sanders' classification. AOFAS Hindfoot and SF 36 scores were collected at final follow-up.

    RESULTS: Anthropometric data, Bohler's and Gissane's angles, AOFAS and SF 36 scores were not significantly different. Pre-operative duration was 12.3 days in ORIF and 6.9 days in APSF. Post-operative duration was 7.3 days vs 3.8 days. Duration off work was 6.2 months vs 2.9 months.

    CONCLUSION: The APSF group was able to have surgery earlier, go home faster, and return to work earlier. This study was not powered to demonstrate a difference in wound complication rates.

    Arthroscopic posterior cruciate ligament (PCL) reconstruction carries some risk of complications, including injury to the neurovascular structures at the popliteal region. We describe a delayed presentation of the right leg and foot compartment syndrome following rupture of popliteal artery pseudoaneurysm, which presented 9 days after an arthroscopic transtibial PCL reconstructive surgery. Fasciotomy, surgical exploration, repair of an injured popliteal vein and revascularisation of the popliteal artery with autogenous great saphenous vein interposition graft were performed. Owing to the close proximity of vessels to the tibial tunnel, special care should be taken in patients who undergo arthroscopic PCL reconstruction, especially if there is extensive scarring of the posterior capsule following previous injury. Emergency fasciotomy should not be delayed and is justified when the diagnosis of compartment syndrome is clinically made.

    Posterolateral corner (PLC) laxity of the knee results in rotatory instability, in association with posterior cruciate ligament (PCL) laxity led to a grossly unstable knee. This is a series of eight patients with chronic PLC and PCL laxity treated with arthroscopic quadriceps tendon PCL reconstruction and extraarticular hamstring PLC reconstruction. Seven cases had high tibial osteotomy to address associated genu varus deformity. With prospective pre- and post-operative assessments, there was a significant improvement in the 2000 International Knee Documentation Committee (IKDC) subjective assessment and knee examination, Lysholm-Gillquist and Tegner activity scores, as well as KT-1000 arthrometry measurement after one year in all knees. Surgical treatment of PLC laxity must address coexisting problems of the PCL and mechanical alignment for a successful outcome.

    Post Arthroscopic intra-articular analgesia is a better method to avoid post-operative pain after arthroscopic surgery, thus avoiding the adverse effects of systemic analgesics. In this prospective randomized double blind study conducted on 90 patients, 30 patients in group A received 20 ml of intra-articular saline, 30 patients in Group B received 10 ml of intra-articular saline and 10 ml of 0.25% bupivacaine and 30 patients in Group C received 10 ml of 0.25% bupivacaine, 1 ml (30 mg) of ketorolac and 9 ml of saline intra-articularly. Ambulatory status, duration of analgesia and requirement for supplemented analgesia were compared in these three groups. Patients receiving this intra-articular analgesic combination of bupivacaine and ketorolac required significantly less supplemental postoperative analgesics. This combination significantly prolonged the duration of analgesia. Patients receiving this combination of drugs for intra-articular analgesia ambulated earlier.

    PURPOSE: To histologically evaluate the quality of articular cartilage regeneration from the medial compartment after arthroscopic subchondral drilling followed by postoperative intra-articular injections of autologous peripheral blood stem cells (PBSCs) and hyaluronic acid with concomitant medial open-wedge high tibial osteotomy (HTO) in patients with varus deformity of the knee joint.
    METHODS: Eight patients with varus deformity of the knee joint underwent arthroscopic subchondral drilling of International Cartilage Repair Society (ICRS) grade 4 bone-on-bone lesions of the medial compartment with concomitant HTO. These patients were part of a larger pilot study in which 18 patients underwent the same procedure. PBSCs were harvested and cryopreserved preoperatively. At 1 week after surgery, 8 mL of PBSCs was mixed with 2 mL of hyaluronic acid and injected intra-articularly into the knee joint; this was repeated once a week for 5 consecutive weeks. Three additional intra-articular injections were administered weekly at intervals of 6, 12, and 18 months postoperatively. Informed consent was obtained at the time of hardware removal for opportunistic second-look arthroscopy and chondral biopsy. Biopsy specimens were stained with H&E, safranin O, and immunohistochemical staining for type I and II collagen. Specimens were graded using the 14 components of the ICRS Visual Assessment Scale II, and a total score was obtained.
    RESULTS: Second-look arthroscopy showed satisfactory healing of the regenerated cartilage. Histologic analysis showed significant amounts of proteoglycan and type II collagen. The total ICRS Visual Assessment Scale II histologic scores comparing the regenerated articular cartilage (mean, 1,274) with normal articular cartilage (mean, 1,340) indicated that the repair cartilage score approached 95% of the normal articular cartilage score. There were no infections, delayed unions, or nonunions.
    CONCLUSIONS: Chondrogenesis with stem cells in combination with medial open-wedge HTO for varus deformity correction of the knee joint regenerates cartilage that closely resembles the native articular cartilage.

    We studied 95 patients who underwent knee Arthroscopy under local anaesthesia between JANUARY 1995 till 1997. Materials used were 1% Xylocaine and 0.25% Bupivacaine of 20 mls each combined with midazolam 2 mg and IV pethidine 30 mgm for sedation. The patients were attached to monitors (pulse Oxymeter, ECG and BP and pulse recorders) and blood less field was created using a tornquet. The procedures lasted about 45 minutes. 90 out of 95 patients completed the procedures successfully without any complications. 2 developed respiratory embarrassments and were intubated and ventilated. 3 procedures abandoned and converted to general anaesthesia. The range of procedures done include meniscectomy, meniscal repair, synovial biopsy, debridement for osteoarthrosis, shaving of osteophytes, drilling of cartilage and bones and removal of loose bodies. This study is to show that knee arthroscopy under LA is a safe alternative in hospitals where GA time is limited.

    PURPOSE: To compare clinical and radiological outcomes and failure rates between anatomical and high femoral tunnels in remnant-preserving single-bundle posterior cruciate ligament (PCL) reconstruction.

    METHODS: 63 patients who underwent remnant-preserving single-bundle PCL reconstruction between 2011 and 2018 with a minimum 2-year follow-up were retrospectively reviewed. Patients were divided into two groups according to the femoral tunnel position: group A (33 patients with anatomical femoral tunnel) and group H (30 patients with high femoral tunnels). The femoral tunnel was positioned at the center (group A) or upper margin (group H) of the remnant anterolateral bundle. The position of the femoral tunnel was evaluated using the grid method on three-dimensional computed tomography. Clinical and radiological outcomes and failure rates were compared between the groups at the 2-year follow-up.

    RESULTS: The position of the femoral tunnel was significantly high in group H than in group A (87.4% ± 4.2% versus 76.1% ± 3.7%, p

    A 38-year-old female presented with a 10-month history of right shoulder pain with impingement symptoms. She was diagnosed on magnetic resonance (MR) imaging to have supraspinatus tendon tear and degenerative changes contributing to subacromial impingement. She also had lipoma arborescens of the subacromial-subdeltoid bursa, an uncommon condition in a particularly rare location. Lipoma arborescens is a benign intra-articular condition characterized by lipomatous proliferation of synovium with replacement of subsynovial tissue by mature adipocytes. It is typically a monoarticular process affecting the knee. Due to the presence of pathognomonic fat, diagnosis is usually straightforward with MR as the preferred imaging modality.

    A 29-year-old man, who was a medical intern presented with history of recurrent shoulder dislocation. Radiographs
    and computed tomography imaging revealed a bony bankart lesion with glenoid bone loss of 25% with moderate
    Hill- Sachs lesion. Latarjet surgery was performed. At post-operative 8 months, the patient experienced pain and
    clicking in the left shoulder while performing cardiopulmonary resuscitation. At post-operative 1 year, magnetic resonance arthrography showed a united coracoid graft and intact posterior labrum. Left shoulder diagnostic arthroscopy and removal of Latarjet screws through a limited anterior deltopectoral approach were performed. The symptoms
    pain, clicking and instability sense was caused by either the prominent distal screw or the remnant suture material
    from the anchor which resulted in impingement of the infraspinatus muscle. We recommend the use of image intensifier to check on the position and length of the screw at the end of the surgery to avoid this complication

    Synovial osteochondromatosis is an unusual, rare and benign tumour. This disease is characteristically monoarticular, most commonly found in knee joint, however it is rarely found in the elbow. A 49-year-old Indian man presented to hospital with a 6-month history of pain, swelling, intermittent locking, loss of range of motion of right elbow and a considerable size of elbow with no recollection of associated trauma. Plain radiographs of right elbow showed numerous radiopaque round and oval loose bodies within the right elbow joints. Computer Tomographic (CT) scan showed multiple bony mass within the right elbow joint. Arthroscopic synovectomy, debridement, excisional biopsy and loose body removal combined with miniarthrotomy of the right elbow was performed due to limited exposure for removal of larger loose bodies. Histopathological examination of the tissue sample is consistent with the diagnosis of synovial osteochondromatosis. The clinical and radiological evaluation at 6th month postoperatively showed marked reduction in the volume of the elbow, further improvement of elbow range of motion of this patient and the Mayo elbow performance score before surgery and at 6 months postoperative, with an increase from 50 to 80 points. Synovial osteochondromatosis of the joints is a rare condition. The signs and symptoms are not specific and may be suggestive of other pathology conditions. Arthroscopic synovectomy and removal of loose body is the standard operative procedure till today. However, combination of arthroscopy and miniarthrotomy in cases of large loose bodies may provide a good clinical and functional outcome.

    Mesenchymal stem cells (MSCs) exert potent immuno-regulatory activities on various immune cells and also differentiate into various mesodermal lineages besides retaining a distinct self-renewal ability. Such exclusive characteristics had enabled MSCs to be recognised as an ideal source for cell-based treatment in regenerative medicine and immunotherapy. Thus, considering MSCs for treating degenerative disease of organs with limited regenerative potential such as cartilage would serve as an ideal therapy. This study explored the feasibility of generating human cartilage-derived MSCs (hC-MSCs) from sports injured patients and characterised based on multipotent differentiation and immunosuppressive activities. Cartilage tissues harvested from a non-weight bearing region during an arthroscopy procedure were used to generate MSCs. Despite the classic morphology of fibroblast-like cells and a defined immunophenotyping, MSCs expressed early embryonic transcriptional markers (SOX2, REX1, OCT4 and NANOG) and differentiated into chondrocytes, adipocytes and osteocytes when induced accordingly. Upon co-culture with PHA-L activated T-cells, hC-MSCs suppressed the proliferation of the T-cells in a dose-dependent manner. Although, hC-MSCs did not alter the activation profile of T cells significantly, yet prevented the entering of activated T cells into S phase of the cell cycle by cell cycle arrest. The present study has strengthened the evidence of tissue-resident mesenchymal stem cells in human cartilage tissue. The endogenous MSCs could be an excellent tool in treating dysregulated immune response that associated with cartilage since hC-MSCs exerted both immunosuppressive and regenerative capabilities.

    This report illustrates five cases of patients admitted to medical ward in HUKM, diagnosed and treated as septic arthritis over the course of two months. Their age ranged from 32 to 67 years old with one patient had history of monoarticular pain and the other four had polyarticular pain. Two of these patients had pre-existing joint disease, namely gouty arthritis and rheumatoid arthritis, and another patient with background history of mixed connective tissue disease on long term steroid therapy. The diagnosis of septic arthritis was made mainly from clinical assessment, supported by synovial fluid assessment and blood investigations. All patients received minimum of two weeks intravenous antibiotic followed by one month course of antibiotic. All of them had arthrocentesis for diagnostic and therapeutic purposes and two had laparoscopic arthroscopy with wash out done.
