No results posted yet for this study

Summary

In total knee arthroplasty (TKA), the relationship between implant design, soft tissue balance, neuromuscular contributions, and rehabilitation strategies on patient satisfaction and functional outcomes is highly complex and poorly understood. The investigators will prospectively study the effects of these factors using in vivo assessments preoperatively, and postoperatively. Computer simulation models will also be used to analyze lower extremity biomechanics.

Conditions

  • Total Knee Arthroplasty (TKA)

Interventions

BEHAVIORAL

Home Strengthening Exercises

The intervention group will perform unsupervised home strengthening exercises for the hip abductors in addition to standard physical therapy, while the control group will receive standard physical therapy alone.

OTHER

Standard Physical Therapy

Physician determined standard of care for individual TKA patients.

OTHER

Preoperative Assessments

Assessments will include: * TUG (timed up and go test) \>12 sec indicates increased fall risk * Tandem balance test \< 10 sec indicates increased fall risk * Sit to Stand test (age based norms) * Knee Range Of Motion (ROM) * Quadriceps and hamstring strength (MMT or hand held dynamometer) * Lower Extremity Functional Score (LEFS questionnaire)
