Arthroscopic In Situ Fixation of Osteochondral Fragments on the Weightbearing Area of the Knee Joint With a Single Anchor.

Osteochondral fracture of knee joint occurring in the femur is a serious clinical trauma. The presence of osteochondral fragments in the knee joint often necessitates surgery. Arthroscopic repair is a minimally invasive treatment, and there are many methods, among which suture anchor is often adopted by clinicians because of its obvious advantages such as simplicity. In the past, there were many methods for fixing osteochondral fragments, but using suture anchors to fix free osteochondral fragments has become a common approach. Moreover, the local mechanical environment will also be affected because of the increase in the number of bone channels. In this report, we describe a method for fixing 1 or 2 osteochondral fragments using a single suture anchor based on the mechanical characteristics of the femoral weightbearing region of the knee joint. We use relevant case reports to introduce our technology. Through the application of our improved technique, the arthroscopic repair of osteochondral fractures in the weightbearing area of femur can be more convenient and more economical, and the rehabilitation of patients will not be affected.
