Unicompartmental Knee Arthroplasty (UKA)

Indicated in isolated medial/lateral compartment OA with intact ligaments. Advantages: smaller incision, bone preservation, faster rehab, more natural kinematics. Contraindications: inflammatory arthritis, tricompartmental OA, fixed deformity >10° varus/valgus, flexion contracture >15°, ligament deficiency. Survivorship improving with better implants and patient selection. Revision to TKA possible if progression occurs.
