Abstract

PURPOSE: To report the advantages and the results of arthroscopic removal of loose bodies by posteri-or-posterior triangulation, using the posteromedial and posteroleteral portal.
MATERIALS AND METHODS
Sixteen cases in this study had loose bodies in the posterior compartment of the knee joint; nine cases in the posteromediaI, three cases in the posterolateral and four cases in the both compartments. Under the supine position, the knee is flexed to a 90 angle, and an obturator was inserted in the posterolateral compartment through the fat areolar tissue eliminating the loose bodies in the posterior compartment. RESULT: In sixteen cases we eliminated all loose bodies under arthroscopy which were in the posterior compartment of the knee joint and there was no complication such as saphenous nerve palsy, common peroneal nerve palsy, or the rupture of popliteal artery.
CONCLUSION
Arthroscopic removal of loose body in the posterior compartment of the knee joint using posterior-posterior triangulation was considered as one of the useful methods in terms of safety and good visualization.
