PURPOSE: The aim of the present study was to compare the effect of pre-operative and post-operative physical therapy versus post-operative physical therapy alone on pain and recovery of function after total knee arthroplasty. SUBJECTS AND METHODS: Fifty patients (18 males and 32 females) ranging in age from 48 to 80 years (mean 63.28, SD 9.44) participated in a 6-week two-arm randomized rater-blinded trial. One group received pre- and post-operative physical therapy whereas the other group received only post-operative physical therapy. Pain and function were measured with a visual analogue scale and a lower extremity functional scale at baseline (pre-operative) as well as week 3 and week 6 post-operative. RESULTS: The differences in pain intensity and functional score at week 3 and week 6 post-operative remained statistically insignificant between the two groups. CONCLUSION: The reduction of pain and recovery of function was similar in subjects who received pre- and post-operative physical therapy and those who received only post-operative physical therapy after total knee arthroplasty. Additional pre-operative physical therapy did not bring about any further improvement in pain intensity or recovery of function after total knee arthroplasty.
