Return to activity following revision total hip arthroplasty

Area of Science:

• Orthopedic Surgery
• Arthroplasty Research
• Patient Outcomes

Background:

• Global demand for revision total hip arthroplasty (RTHA) is rapidly increasing.
• RTHA is projected to more than double in the next 1-2 decades.
• This study investigates functional recovery after RTHA in a UK population.

Purpose of the Study:

• To evaluate the return to function following revision total hip arthroplasty (RTHA).
• To identify factors influencing outcomes and patient satisfaction after RTHA.
• To assess the impact of RTHA on physical activity and daily living.

Main Methods:

• 118 patients (132 RTHAs) were assessed at a mean follow-up of 7.9 years.
• Preoperative and postoperative data collected included UCLA scores, Oxford Hip Scores (OHS), EQ-5D, and satisfaction.
• Univariate and multivariate analyses were performed to identify predictors of outcomes.

Main Results:

• Mean UCLA activity scores improved significantly post-RTHA, with 37% showing improvement and 49% achieving moderate activity levels.
• Preoperative UCLA scores predicted long-term activity levels. Social deprivation, revision for periprosthetic fracture, and lower preoperative OHS predicted poorer hip function.
• Difficulties with activities of daily living were linked to deprivation, comorbidities, and revision for fracture or infection. 79% of patients were satisfied.

Conclusions:

• Revision total hip arthroplasty (RTHA) enables a return to preoperative activity levels for most patients.
• One-third of patients experience an increase in activity levels post-RTHA.
• Revision for periprosthetic fracture or dislocation is associated with worse outcomes and lower patient satisfaction.
