Physical Therapy Following Total Hip Arthroplasty

Study Overview
=================
Brief Summary
-----------------
130 patients undergoing primary unilateral total hip arthroplasty through anterior approach were enrolled and randomized into one of two groups. One group received standard of care clinic-based physical therapy postoperatively (clinic PT) while the other group underwent progressive home-based exercises to do after surgery (home PT). Patient surveys with Hip Osteoarthritis Outcome Scores (HOOS) and SF12v2 scores for both groups were obtained before surgery as well as 6, 14, and 24 weeks postop. Patients had the option to crossover into the other study group at their 6-week follow-up visit.

Inclusion Criteria: scheduled to undergo primary unilateral anterior total hip arthroplasty for the treatment of arthritis under the care of the Principal investigator available for follow ups postoperatively Exclusion Criteria: Age <18 or > 75 Preoperative BMI ≥ 40 Revision (i.e., non-primary) THA procedures Patients who have undergone THA in contralateral hip within the past 6 months Patient is scheduled for or anticipating THA on contralateral limb within 6 months Patients with an active infection (at the time of screening through surgery, as this is a surgical contraindication) Current co-morbidities such as alcohol or drug addiction, and/or mental disorders could potentially interfere with study participation Cognitive deficit or significant mental impairment that would, in the opinion of the investigator, impede patient self-reporting History of severe osteoporosis, metabolic bone disease, radioactive bone disease, or tumor in the bone surrounding the hip joint History of significant neurological and/or musculoskeletal disorders that may adversely affect gait after THA History of inflammatory hip arthritis History of septic hip arthritis in affected hip Patients requiring discharge to a rehabilitation center, skilled nursing facility, long-term care center, or convalescent home Non-English speaking Unable to give informed consent Currently enrolled in another therapeutic study for THA
