Background: Following transfemoral amputation (TFA), contralateral limb overuse leads to osteoarthritis (OA). Explanations include gait abnormalities, increased knee load, and hopping activities without prosthesis. Unilateral TFA patients may require total knee arthroplasty (TKA) to improve function.

Purpose: Determine benefits of standard physical therapy (PT) and augmented by high intensity, whole-body strengthening program.

Case Description and Methods: Patient with TFA, limited community ambulator and left knee OA, underwent TKA to restore function. PT examinations, interventions, and outcomes at 1-week pre-TKA to 1-year post-TKA; outcomes measures were Single Leg Stance Test (SLST), Four Square Step Test (FSST), Timed Up and Go Test (TUG), and Six Minute Walk Test (6MWT).

Finding: Patient achieved functional independence, gait, lower extremity strength and active range of motion (AROM) goals.

Outcomes and Conclusion: Outcomes in TUG and FSST equaled age and sex matched non-amputees. Standard TKA PT protocols contributed to patient success, while high intensity, whole-body strengthening program contributed to patient achievements.
