PURPOSE OF THE STUDY:
The purpose of this study was to evaluate clinical and functional results for a series of patients undergoing unicompartmental knee arthroplasty (UKA) at mid-term follow-up.

MATERIAL AND METHODS:
This study included 32 patients with isolated medial compartment arthritis who underwent unilateral UKA. Outcomes were assessed using pre- and postoperative Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) scores and Knee Society Score (KSS) metrics.

RESULTS:
On physical examination at a follow-up of at least 5 years, mean knee flexion was 121° , mean knee extension was 2°, and mean varus angulation was 2°. At post-operative evaluation, the mean WOMAC score was 96.12 and the mean KSS score was 93. Pre- and postoperative WOMAC and KSS scores were evaluated by paired Student's t-tests; p < 0.001 determined a highly significant difference.

DISCUSSION:
Early UKA designs had poor outcomes. Newer implant designs and specific patient selection criteria have been reported to be associated with improved outcomes. This study examined mid-term outcomes (mean duration of follow-up, 5 years).

CONCLUSION:
The clinical and functional results of UKA at 5-year follow-up were shown to be satisfactory. Longer follow-up is needed to determine whether UKA provides satisfactory long-term outcomes.
