The purpose of this study is to define the clinical features and characteristics of radial tears in the root of the posterior horn of the medial meniscus and to report the outcome of arthroscopic treatment. Arthroscopic meniscus surgery was performed on 7,148 knees. Of those, 722 (10.1%) were radial tear in the root of the posterior horn of the medial meniscus. We reviewed the medical records from a random sample of 67 subjects studied (mean age 55.8 years, range 38-72, mean follow-up period 56.7 months, range, 8-123), which included surgical notes and detailed arthroscopic photographs of 70 knees. All patients were treated with arthroscopic partial meniscectomy. The age distribution, preoperative physical signs, results of magnetic resonance imaging , body mass index, and surgical findings of the study subjects were analyzed and the clinical results were graded with the Lysholm knee scoring scale and a questionnaire. Radiologic evaluation consisted of preoperative and at the latest follow-up radiographs. Eighty percent of the patients were older than 50 years, and 80.6% were either obese or morbidly obese. The mean Lysholm score improved from a preoperative value of 53 to a value of 67. The average preoperative Kellgren-Lawrence radiograph grade was 2 (range 0-3 points), a value that increased to 3 (range 2-4) at the latest follow-up, which showed a significant worsening. The preoperative MRI was reevaluated after the arthroscopic confirmation of a medial meniscal root tear. A tear could be demonstrated in only 72.9% of the patients, the rest of whom demonstrated degeneration and/or fluid accumulation at the posterior horn without a visible meniscal tear. Radial tears in the root of the medial meniscal posterior horn, which may not be visible in about one-third of the preoperative MRI scans, are common. That type of meniscal tear is strongly associated with obesity and older age and is morphologically different from the degenerative tears that often occur in the posterior horn. Partial meniscectomy provides symptomatic relief in most cases but does not arrest the progression of radiographically revealed osteoarthritis.

Closed reduction and pinning is superior to open reduction and pinning for the treatment of pediatric supracondylar humerus fractures. In the case of technical insufficiencies open reduction and pinning through a posteromedial incision is an alternative treatment for decreasing the surgical time and complications. Complications was not caused in either group by the delayed surgical timing compared to reports in the literature.

The diagnosis of necrotizing fasciitis should be considered for any individual who has unexplained limb pain, especially if that person has diabetes mellitus or chronic liver disease. There was no difference in mortality rates between patients with or without amputation. The primary treatment is early and aggressive debridement of involved skin, subcutaneous fat, and fascia.

We performed a prospective, randomized study on 76 patients (82 knees) scheduled for total knee arthroplasty to determine the effect of tourniquet release and hemostasis on the peri-and postoperative blood loss. Patients were randomly divided in two groups. Posterior cruciate retaining tricompartmental total knee prostheses were used in all. In group 1, the tourniquet was deflated intraoperatively after the prosthetic components were settled and hemostasis was done. In group 2, the tourniquet was released after the wound was closed and a compressive bandage was applied. Mean blood drainage was 880.85 ml (320-1,315) in group 1 and 745.36 ml (220-1,175) in group 2 (p=0.03). The mean number of blood transfusions given, hemoglobin and hematocrit values, operation time, and tourniquet time were similar in both groups. Intraoperative tourniquet release and hemostasis does not reduce total blood loss in total knee arthroplasty.RØsumØ Nous avons exØcutØ une Øtude prospective et randomisØe sur 76 malades (82 genoux) programmØ pour arthroplastie du genou total pour dØterminer l'effet de la levØe de garrot-hØmostase sur le perte de sang per-et postopØratoire.

Fixation with the PHILOS plate is a near-ideal technique with a high union rate in the treatment of proximal humeral fractures.

We consider the best treatment of synovial cysts originating from proximal tibiofibular joint and causing peroneal nerve palsy to be total surgical removal as soon as possible after the diagnosis is made. It should be kept in mind that despite surgical treatment the neurological symptoms may not recover.

Bone tunnel enlargement associated with anterior cruciate ligament (ACL) reconstruction has recently become a topic of interest in the literature. This association was examined, along with the effect of femoral and tibial tunnel enlargement on the clinical results of ACL reconstruction performed with either bone-patellar tendon-bone (BPTB) or hamstring (HST) autografts. Forty-six patients underwent arthroscopic ACL reconstruction (23 receiving BPTB autograft and 23 HST) between March 1999 and July 2001. Thirty patients (13 receiving BPTB autograft and 17 HST) completed the last clinical and radiologic evaluations and were included in the study. The mean age of patients in the HST group was 29.8 years (range 18-39) and that in the BPTB group was 27.6 years (range 20-37). The mean follow-up period was 24.6 months (range 12-36) in HST group and 18.5 months (range 12-40) in BPTB group. The effect of tunnel enlargement on the clinical results was evaluated by comparing preoperative and postoperative Lysholm, Tegner, and International Knee Documentation Committee scores and ligament laxity measurements between and within the groups. Postoperative femoral and tibial tunnel diameters in both groups were significantly larger than their corresponding preoperative tunnel diameters. In an intergroup evaluation, the enlargement of the tibial tunnel was similar in both groups (P=.556), but the femoral tunnel diameter was significantly larger in the HST group than in the BPTB group (P>.001). Preoperative laxity of the knees significantly improved after the operations in both groups, but no difference between the groups was evident at the final follow-up visit. No correlation between tunnel widening and the clinical results of the BPTB and HST procedures was observed.

BCP can be successfully used as a bone substitute. The radiographic remodeling and consolidation process of BCP was found to be different from that of beta-tricalcium phosphate. In our patients with more than 2 years of follow-up, BCP granules did not completely remodel. As a result, this clinical study demonstrated that calcium phosphate granules containing hydroxyapatite had a long period of "creeping substitution" that lasts longer than 2 years.
