Summary

This study is a randomized controlled trial comparing total knee arthroplasty (TKA) to unicompartmental knee arthroplasty (UKA) in patients with no to moderate anteromedial knee osteoarthritis. TKA patients will receive the Zimmer Persona (Warsaw, IN) posterior cruciate retaining total knee arthroplasty, while UKA patients will receive the Biomet Oxford (Warsaw, IN) mobile bearing unicompartmental knee arthroplasty.

Outcome measures will include Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Oxford Knee Score (OKS) questionnaires, as well as biomechanics and EMG analysis from the investigating gait lab.

The investigators hypothesize that post-operative UKA patients will display higher clinical scores using WOMAC and OKS questionnaires, and superior biomechanical analysis measures. The investigators further hypothesize that the biomechanics data will assist in the understanding of the outcome score differential both pre- and post-operatively in both groups, as well as between-groups.

Total follow up period will be two years.
