2. Fig 1
Right knee arthroplasty, viewed from anteromedial portal with 4-mm, 30° arthroscope. (A) The femoral component and (B) patella component articulation are seen. (C) Anterior scar tissue before debridement is seen within the patellofemoral joint. Anterior scar tissue can impede visualization of the lateral compartment after total knee arthroplasty.

3. Fig 2
Right knee, viewed from anterolateral portal. (C) The lateral compartment and lateral joint show synovium and scar tissue overlying the popliteus between (A) the lateral femoral component and (B) the lateral tibial polyethylene component.

4. Fig 3
Posterolateral region of right knee after scar resection. (A) The arthroscope is in the anterolateral portal, and this allows direct visualization of the popliteal tendon. Using an accessory lateral portal, (B) the arthroscopic scissors (Acufex) release the popliteal tendon off of its femoral insertion.

5. Fig 4
View of posterolateral right knee from anterolateral portal. Arthroscopic debridement has been completed, and the popliteal tendon and associated scar tissue have been removed from the knee. There is no evidence of impingement between (A) the femoral component and (B) the tibial component. The black arrow demonstrates the lateral knee after complete popliteal resection from the joint.

6. Fig 5
Arthroscopic view of transected popliteal tendon of right knee from anterolateral portal. After the release, there was significant tendinopathy with fatty infiltration and degeneration (arrow).
