Abstract
Tears of the posterior horn of the menisci often call for arthroscopic surgery to the medial or lateral compartments of the knee. In osteoarthritis knees, or when there is anterior cruciate ligament deficiency or joint tightness, using conventional anterolateral and anteromedial portals can be difficult. This is so also in very large adult knees. There is a risk of iatrogenic damage to the articular surfaces and structures of the knee.
The establishment of an accessory medial and/or lateral portal for instrumentation makes it easy and safe to perform arthroscopic surgery to the posterior medial and/or lateral compartments. The author used this technique in 103 patients in whom access to the posterior compartments was problematic.
The simple but effective technique is particularly useful for the inexperienced surgeon or arthroscopist in training.
