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

Video Transcription

Video Summary

In a video on NPFL (nonsurgical patellofemoral treatment) reconstruction, the speaker discusses the importance of properly placing tunnels to avoid complications. Tunnel malposition can lead to various issues such as patella overload, instability, arthrosis, and increased compressive forces. The femoral tunnel placement is a significant risk factor for patella fractures. The speaker suggests using a large C-arm and true lateral view when performing the reconstruction and emphasizes the importance of making sure the graft loses inflection after being attached to the patella. The speaker also mentions a study that showed errors in tunnel placement are common when relying on palpation alone. If a graft is misplaced, it should be repositioned correctly and if intact, can be mobilized within the tunnel. In conclusion, using fluoroscopy with palpation is recommended for accurate tunnel placement, and the graft should have appropriate tension and mobility. If revision is needed, graft length can be increased through various techniques. The video credits Bill Post for his assistance in the study.
