The purpose of this research study was to evaluate pain, strength, balance, and function in subjects before and after total knee arthroplasty. Thirteen subjects were tested prior to total knee arthroplasty. Seven of the original subjects returned to the laboratory and were tested one month after knee replacement surgery. At each testing session subjects completed questionnaires including a pain visual analog scale (VAS), Falls questionnaire, global rating of knee function, Western Ontario McMaster Universities (WOMAC) osteoarthritis index, and Knee Outcome Survey Activities of Daily Living Scale (KOS-ADLS). Strength was tested via unilateral, isometric squat. Knee range of motion was measured using a standard goniometer. Functional activities including walking, sit to stand transfers, and stepping on and off a curb were assessed using the Balance Master Force Plate system (Neurocom International). Balance activities including tandem walk, modified clinical test of sensory interaction on balance (mCTSIB), limits of stability (LOS), and sensory organization tests (SOT) were also assessed using the SMART Equitest (Neurocom International). There was a trend towards decreased pain on VAS post- surgery although the results were not significantly different (p = 0.0585). Subjective rating of function was improved on the composite WOMAC Osteoarthritis Index score (p = 0.0313). No differences were found after surgery for strength in the involved limb, balance tasks, or ability to perform functional activities. From this study we conclude that total knee arthroplasty does not have a deleterious effect on function or balance in the immediate post-operative period even through the knee is still in an acutely inflamed state. Further testing is needed to evaluate the effect of TKA on more strenuous functional activities and balance tasks and at larger post-operative intervals. / School of Physical Education, Sport, and Exercise Science
