Unicompartmental Knee Arthroplasty vs High Tibial Osteotomy (HTO)

Both indicated for isolated medial compartment OA in younger active patients. HTO: joint-preserving, shifts weight-bearing axis, delays arthroplasty. UKA: joint-replacing, preserves kinematics, faster recovery. HTO better for younger, high-demand, ligament-intact; UKA better for older, lower-demand. Revision: UKA easier conversion to TKA than failed HTO.
