AANA/SOMOS Enduring Knee Program 2025-Debate: 45 y.o. MSGT With Meniscectomy x 2, Significant Medial OA and Varus

Video Transcription

Video Summary

The transcript captures a debate on treating isolated medial knee osteoarthritis in younger, active patients (often military). One speaker argues for unicompartmental knee arthroplasty (UKA/“uni”) as a technically feasible, easier-to-recover “bridge” procedure compared with high tibial osteotomy (HTO), citing similar midterm survivorship, faster return to activity, and the importance of strict indications—especially a pristine lateral compartment. Failures are typically polyethylene wear or arthritis progression elsewhere. A colleague emphasizes that UKA patients are often very satisfied; patellofemoral arthritis may be less consequential than lateral disease, and failure rates are only modestly higher than total knee arthroplasty.<br /><br />A counterpoint presentation argues HTO is preferable for very active younger patients (e.g., needing to run for military fitness), as a joint-preserving realignment that may allow broader activity and lower conversion-to-total rates, despite longer recovery and risks (hinge fracture, nonunion, difficult later TKA). Discussion highlights patient goals, activity reality, correction targets, bracing trials, and skepticism about newer “MISHA” implants.
