AJSM July 2026 Podcast: Association Between Preoperative Joint Line Convergence Angle and Clinical Outcomes After Isolated Medial Meniscus Posterior Root Tear Repair

While coronal malalignment influences outcomes after medial meniscus posterior root tear (MMPRT) repair, alignment parameters such as the hip-knee-ankle angle (HKAA) may not fully capture the biomechanical setting of the medial compartment. The joint line convergence angle (JLCA) reflects the intra-articular environment but has not been well studied as a prognostic factor after MMPRT repair.

 

In conclusion, the preoperative JLCA was an independent predictor of clinical outcomes after isolated MMPRT repair. Incorporation of the JLCA into a preoperative assessment may improve patient counseling and risk stratification and help identify patients who could benefit from adjunctive strategies aimed at optimizing the medial compartment's biomechanical environment.
