Repair of popliteomeniscal fascicles tear using a posterior transseptal portal fixes hypermobile lateral meniscus.

PURPOSE This study investigates the effects of the all-inside repair of posterosuperior popliteomeniscal fascicle (PMF) on lateral meniscus stabilization using a posterior arthroscopic approach. METHODS Between 2015 and 2018, 17 patients with hypermobile lateral meniscus (HLM) underwent posterior knee arthroscopy for PMF repair. The all-inside repair was performed through posteromedial transseptal and posterolateral portals using a suture hook technique. Patients were clinically assessed based on IKDC and Lysholm scores. RESULTS Both IKDC and Lysholm scores improved significantly after an average follow-up of 3.5 years (P < 0.001). No patients underwent reoperation, and no complications associated with posterior knee arthroscopy were reported. CONCLUSION The all-inside suture hook technique using posterolateral and posteromedial transseptal portals fixes HLM with excellent IKDC and Lysholm scores. LEVEL OF EVIDENCE Level IV.
