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.
