Arthroscopic treatment of iliopsoas tendinitis after total hip arthroplasty with acetabular cup malposition: Two case reports

Figure 6 Arthroscopic findings in Case 2. A: Copious metal transfer on the ceramic head might have originated from a previous dislocation-and-reduction maneuver (anterolateral viewing portal); B: This metal transfer was demonstrated on the margin of the ceramic liner (anterior viewing portal); C: Metal transfer was also observed at the bottom of ceramic head, which might indicate impingement of the implants on one another (anterolateral viewing portal); D: Chronic synovitis around the iliopsoas tendon (arrow in B) was identified, and tendon release with partial synovectomy was performed (anterolateral viewing portal).
