Arthroscopic visualization before and after reverse notchplasty. Side-by-side arthroscopic images of a left knee in the supine position, viewed with a 30° arthroscope through the anteromedial portal with the knee flexed to 90°. (A) Prenotchplasty: Prior to bony resection, the medial femoral condyle (A) obstructs visualization of the posterior joint space, limiting access to the posterior root of the medial meniscus. The medial tibial plateau is labeled (B). The red outline demarcates the non-weightbearing posterior margin of the medial femoral condyle that is targeted for resection to improve access. (B) Postnotchplasty: Following reverse notchplasty, a small portion of the posterior aspect of the medial femoral condyle (A) has been resected. This allows for improved exposure of the posterior root of the medial meniscus (C). A radiofrequency ablation probe (D) is introduced through the anterolateral portal to assist in synovial and bony debridement. The medial tibial plateau (B) remains in view. This technique provides a wider visual corridor to the posterior horn, enhancing both visualization and instrumentation for meniscal root repair.
