Risk factors for arthroscopic popliteal artery laceration.

A case report is presented in which a patient with well-documented pigmented villonodular synovitis sustained a disruption of the popliteal artery without evidence of penetration of the posterior capsule. The patient had had several extensive open synovectomies in the prior 20 years. These included popliteal space exposure and dissection. At the time of open arterial repair, multiple nodules of pigmented scar were noted densely binding the popliteal artery to the surrounding muscle and fascial tissues. The arthroscopist should be aware that distension and instrumentation of the knee joint in such patients should be performed with extreme care to avoid arterial disruption.

Arthroscopic posterior cruciate ligament repair.

This article presents a classic case of posterior cruciate ligament disruption, as an isolated entity, with avulsion of the cruciate from the tibia origin. The treatment is an arthroscopic technique for reimplantation of the posterior cruciate ligament, using the Instrument Maker staple for fixation to facilitate proper reduction of the posterior cruciate, and presents a follow-up with excellent range of motion and stability of the knee.

Anterior cruciate ligament reconstruction using silastic rod technique.

A five-year follow-up of a reconstruction of anterior cruciate ligament technique is presented. The study involved a total of 18 patients, all evaluated by Feagin's criteria to assess stability and function. Overall assessment showed 83.3% of patients perfect, or near perfect; and 11.1% of patients good. On subjective evaluation, 93.5% had good to excellent results. Objective evaluation showed 94.4% overall had good to excellent stability. The microsurgical technique is also presented. Eighteen patients, approximately 32.9 months postreconstruction, showed over 90% good to excellent results. Although the series is small, the results are encouraging.

A technique for lateral retinacular release.

The following article does not intend to present indications or contraindications for lateral retinacular release as a therapeutic measure; it presents a simple, effective method of doing a complete lateral retinacular release with a minimal degree of effort for the surgeon, if he or she decides on release as a therapeutic measure. A carefully designed scissors that allows a complete release of the lateral retinaculum in a matter of moments is described, as well as a basic technique for a complete release. This method has given the author satisfactory release in all cases, with a minimal degree of complications. The instrumentation is basic, effective, and readily available.
