Arthroscopic technique for the treatment of patellar chondral lesions with the patient in the supine position.

We describe an arthroscopic approach for the treatment of patellar chondral lesions with the patient in the supine position. This approach can be used to perform certain procedures such as matrix autologous chondrocyte implantation and autologous matrix-induced chondrogenesis. It is possible to perform these arthroscopic techniques working at an angle perpendicular to the patellar joint surface.

Arthroscopic treatment of unstable total hip replacement.

Hip arthroscopy may be useful in the diagnosis and treatment of apparently well-implanted but unstable total hip replacement prostheses. We present 2 cases of arthroscopically assisted capsular tightening in unstable total hip replacements. Both cases had significant capsular laxity.
