Partial lateral patellar facetectomy for treatment of arthritis due to lateral patellar compression syndrome.

Purpose: The purpose of this study was to investigate the intermediate-term results of a retrospective clinical trial designed to establish the value of lateral retinaculum release of the patella in conjunction with partial lateral patella facetectomy in patients with stage III or stage IV patellofemoral arthritis.

Methods: Between October 1992 and January 2005, all patients undergoing arthroscopy, lateral patellar retinaculum release, and lateral patella facetectomy were evaluated. In total, 66 knees in 63 patients (89%) were available for evaluation at a mean of 60 months after the index surgery.

Endoscopic ACL reconstruction using stryker biosteon cross-pin femoral fixation and interlock cross-pin tibial fixation.

Hamstring tendon autografts have, over the past decade, increasingly become the graft of choice for anterior cruciate ligament (ACL) reconstructions. Studies have shown that multiply stranded hamstring grafts have superior biomechanical characteristics when compared to patellar tendon autografts. Harvests of hamstring tendons have been shown to cause less donor-site morbidity than the harvest of patellar bone-tendon-bone grafts.

Current status of meniscal transplantation.

The current status of meniscal transplantation is reviewed. Results of 36 meniscal transplants carried out by the authors are also presented.

Complications of thermal energy in knee surgery--Part II.

With the theoretical and reported complications of thermal energy use in the knee, an analysis of potential risks and benefits should be done on a case-by-case basis. Many of the basic science studies may not be directly applicable to clinical practice because they use normal (i.e.

Clinical and biomechanical evaluation of the unloading brace.

A study based on the biomechanical study of the OAdjuster unloading brace (dj Orthopedics, Vista, Calif) was conducted clinically in 28 patients. Mechanical axis of the knees tested ranged from 100 valgus to 15 degrees varus. Patients were then assessed using a questionnaire, and technician bone scans at 1-, 3-, and 6-month follow-up.
