A published study showed encouraging clinical results at midterm follow-up among patients who underwent unicompartmental knee arthroplasty for osteoarthritis of the medial knee compartment.

Researchers performed survival analysis for 91 patients who underwent medial unicompartmental knee arthroplasty (UKA) with the Journey Uni prosthesis (Smith & Nephew) for OA at a minimum of 30 months postoperatively, and obtained patients’ oriented questionnaires and KOOS scores. Researchers also performed a retrospective chart review and radiological analysis of component alignment for all patients preoperatively and at 6 weeks postoperatively.
