Limited predictive value of pre-surgical level of functioning for functioning at 3 and 12 months after TKA

Purpose A total knee arthroplasty (TKA) is a cost-effective option to relieve pain and improve knee function in patients suffering from osteoarthritis. However, results differ among patients. The predictive value of pre-surgically assessed factors on the level of functioning after 3 and 12 months was investigated in this study.
