Overview
Brief Summary
Unicompartmental Knee Arthroplasty (UKA) is the principal surgical alternative to Total Knee Arthroplasty (TKA) in patients with end-stage unicompartmental tibiofemoral osteoarthritis (OA) of the knee. The current post-marketing surveillance study aims to monitor GMK-UNI monocompartmental knee prosthesis performances over a 10-year time period.

Outcomes
Primary Outcomes
New Knee Society Score (KSS)
Time Frame: Preoperative, 3 months, 1, 2, 3, 5, 7 and 10 years
The new Knee Society Knee Scoring System is both physician and patient derived. It includes versions to be administered preoperatively and postoperatively. It has an initial assessment of demographic details, including an expanded Charnley functional classification. The objective knee score, completed by the surgeon, includes a VAS score of pain walking on level ground and on stairs or inclines, as well as an assessment of alignment, ligament stability, and ROM, along with deductions for flexion contracture or extensor lag. Patients then record their satisfaction, functional activities, and expectations. Given the diverse activity profiles of many contemporary patients, the functional component of the score was improved to include a patient-specific survey, which evaluates features such as standard activities of daily living, patient-specific sports and recreational activities, patient satisfaction, and patient expectations
Secondary Outcomes
- Kujala Score(3 months, 1, 2, 3, 5, 7 and 10 years)
- Survival of the implant(3 months, 1, 2, 3, 5, 7 and 10 years)
- Safety of the implant(Intraoperative, 3 months, 1, 2, 3, 5, 7 and 10 years)
