Video 1. Arthroscopic medial release for medial abrasion phenomenon. An example of stage III medial compartment osteoarthritic knee with medial abrasion phenomenon treated by arthroscopic medial release is shown in this video clip. This is a 78 years old female suffering from left knee pain for more than 10 years. The arthroscopic examination revealed tightness of the medial facet of the patellofemoral joint and obliteration of the inferomedial region of the patella by hypertrophied medial plica and synovitis tissue. The abrasion phenomenon between fibrotic medial plica and medial femoal condyle could be reproduced by manipulation. After arthroscopic medial release, the medial gutter and the damaged medial femoral condyle could be clearly visualized and the medial abrasion phenomenon was also eliminated.

Video 2. Evidence of cartilage regeneration after ACRFP by a second-look arthroscopy. This 56 years old lady received ACRFP and have had experienced a satisfactory outcome until three years later when she suffered from a falling down accident with the same knee injured. We therefore had the chance to perform a second-look arthroscopy and visualized the evidence of cartilage regeneration over her previous chondral defect on the medial femoral condyle.
