2021 Annual Meeting Knee Access Pass-I Misplaced my MPFL Tunnel

Video Transcription

Video Summary

The speaker discusses the critical importance of accurate tunnel placement in MPFL reconstruction, emphasizing that malposition can cause patella overload, instability, arthrosis, and fractures. Using fluoroscopy (C-arm) and palpation together improves accuracy compared to palpation alone, which often leads to significant errors even among experts. If the tunnel is misplaced and causes symptoms, revision surgery may involve repositioning the graft. Sometimes, the intact graft can be mobilized and reused rather than replaced. Proper tensioning is crucial to allow normal patella movement. Techniques like graft lengthening may be needed in revisions. Accurate placement and fixation are key to successful outcomes.
