exudates and Knee-Injuries

A high incidence of joint laxity has been reported among Asians compared with Western populations, but clear differences between more specific ethnic populations have not been established. This study aimed to determine the average knee laxity in the Malaysian and Jordanian populations.. Jordanian and Malaysian medical students from our institution were invited to participate in the study. General demographic data and factors affecting joint laxity were obtained from each participant using a printed questionnaire. Both knees were examined using the anterior drawer test while in 90° of flexion. Knee laxity was measured by three separate independent investigators through a knee laxity tester.. One hundred and eighty-six participants (95 females) were enrolled in the study. Among them, 108 Malaysians participated. The Jordanians had significantly higher knee laxity in both knees compared with the Malaysians. The mean average right knee laxity for Jordanians was 2.98 mm vs. 2.72 mm for Malaysians (P = 0.005). Similarly, the mean average left knee laxity for Jordanians was 2.95 mm, while for Malaysians, it was 2.62 mm (P = 0.0001). Furthermore, smokers had significantly more laxity in both knees. After performing a multivariate linear regression analysis for all factors, race was the only independent factor that affected knee laxity in both knees.. Race is directly associated with knee laxity. Jordanians tend to have more laxity in knee joints compared with Malaysians. Larger multi-center and genetic studies are recommended to establish the racial differences between different ethnic groups.

To evaluate the outcome of reconstruction for chronic grade-II posterior cruciate ligament (PCL) deficiency in Malaysian military personnel.. Medical records of 16 male military personnel aged 25 to 41 years who underwent reconstruction for chronic grade-II PCL deficiency using the quadruple hamstrings tendon by a single surgeon were reviewed. The mean time from injury to surgery was 43.6 (range, 3-104) months. 10 patients had grade-I (n=4), grade-III (n=2), and grade-IV (n=4) lesions of the medial femoral condyles. Seven patients had medial (n=6) and lateral (n=1) meniscus tears. At the 2-year follow-up, patients were asked to complete a questionnaire consisting of the Lysholm score, Tegner activity level, and International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form. Posterior drawer test, KT-2000 arthrometer test for posterior translation of the tibia, and military health grade (MHG) were assessed by an independent assessor.. At the 2-year follow-up, the mean Lysholm score was 83; the score was excellent in 2 patients, good in 9, fair in 4, and poor in one. The mean IKDC subjective score was 74. The median Tegner activity level increased from 5.5 to 6. The posterior drawer test of 11 patients improved to grade I and the remaining 5 remained at grade II. The mean posterior translation of the tibia was 2.4 mm postoperatively; the posterior translation was normal in 8 patients, nearly normal in 7, and abnormal (≥ 6 mm) in one. The MHG improved in 14 patients and remained unchanged in 2. The latter 2 patients had no chondral lesion or meniscus injury. The first one was 40 years old with a postoperative IKDC score of 55 and a Tegner activity level of 2. The second one was 34 years old with a postoperative IKDC score of 65 and posterior translation of the tibia of 6 mm.. Surgical reconstruction for chronic grade-II PCL injury achieved satisfactory outcome and may be appropriate for military personnel.

Between January 1994 to December 1998, 133 patients had a meniscal surgery at University Malaya Medical Centre. Fifty-four patients were assessed and scored with the Lysholm and Tegner scoring system. Twenty-nine patients had partial meniscectomies and 25 had meniscus repair. The outcome was successful in 80% with meniscal repair and 51.7% with partial meniscectomy. The outcome of meniscal repair in this study is comparable to other reported series. However, the failure rate for partial meniscectomy was high.
