Summary

The total knee replacement (TKA) has shown excellent survival. However, some patients were up to 20%, they still had pain and make them dissatisfy after operation. The medial unicompartmental knee arthroplasty (UKA) also has shown excellent survivorship. The patient who underwent UKA fell like normal knee because restoring natural kinematic and biomechanic compare to TKA. However, The previous studies did not include the same characteristic of patient in their studies. Therefor, UKA should be better than TKA. This study will compare TKA to mobile bearing medial UKA or Oxford medial UKA. The mobile bearing UKA is different to fixed bearing UKA. The mobile bearing UKA will be back knee alignment to pre-disease stage, restore knee stability and restore natural knee kinematic and biomechanic. Therefore, patients who underwent mobile bearing UKA will feel like normal knee and restore function to near or nearly normal. The measurement of clinical outcome after knee arthroplasty is questionable. The self-report questionnaire was used in the past. However, this score can not estimate the true function of patients. The patient have shown high score, but they still had pain and did not show satisfy after operation.The performance-based test such as 2-minute walk test (2MWT), 6-minute walk test (6MWT) and Timed get-up-and-go test (TUG) should show the exactly clinical outcome of patient following knee arthroplasty compare to self-report questionnaire. Today, no randomized controlled trial study to compare performance-based test between TKA and mobile bearing UKA. Therefor, this study will compare 2MWT and TUG between TKA and mobile bearing UKA in medial OA knee.
