Changes of and interrelationships between performance-based function and gait and patient-reported function 1 year...

Area of Science:

• Orthopedics
• Biomedical Engineering
• Rehabilitation Science

Background:

• Hip osteoarthritis (OA) significantly impacts patient function and quality of life.
• Total hip arthroplasty (THA) is a common surgical intervention for end-stage hip OA.
• Evaluating functional recovery after THA requires comprehensive assessment methods.

Purpose of the Study:

• To assess functional improvements 1 year after THA in patients with hip OA.
• To investigate the interrelationships between performance-based function, gait, and patient-reported outcomes.
• To compare objective and subjective measures of functional recovery post-THA.

Main Methods:

• Prospective study design involving 34 patients undergoing THA for hip OA.
• Comparison with 25 age- and gender-matched healthy controls.
• Utilized performance-based functional tests, 3D gait analysis, and the Hip disability and Osteoarthritis Outcome Score (HOOS).

Main Results:

• Significant improvements observed in performance-based function and patient-reported outcomes (HOOS) 1 year post-THA.
• Moderate improvements noted in gait kinematics (operated limb) and kinetics (contralateral limb).
• Patient-reported function showed the largest improvement magnitude compared to objective measures.

Conclusions:

• Objective functional improvements post-THA may not fully align with patient-reported outcomes.
• Emphasizes the importance of integrating both subjective (patient-reported) and objective (performance, gait) assessments for a holistic evaluation of THA success.
• Findings guide clinical practice in assessing recovery and patient satisfaction after hip replacement surgery.
