Functional problems and treatment solutions after total hip arthroplasty.

Area of Science:

• Orthopedics
• Physical Therapy
• Biomechanical Engineering

Background:

• Dissatisfaction post-total hip arthroplasty (THA) is often attributed to comorbidities, loosening, or malalignment.
• Some THA patients experience functional deficits without clear radiographic or mechanical causes.

Purpose of the Study:

• To identify soft tissue abnormalities contributing to THA dysfunction.
• To evaluate the effectiveness of tailored physical therapy interventions for these issues.

Main Methods:

• Seventy-eight THA patients with functional complaints at 3 months post-surgery underwent detailed physical exams.
• Utilized gait analysis (videotape, 3D), and isokinetic strength testing to assess function.
• Interventions included physical therapy, electrical stimulation, shoe lifts, and injections.

Main Results:

• Identified muscle weakness (57), tightness (32), limb length discrepancy (11), and malalignment (10) as common issues.
• At a mean 61-month follow-up, 94% of patients achieved good to excellent outcomes.
• Average patient satisfaction was 8.7/10.

Conclusions:

• Comprehensive assessments, including 3D gait analysis, are crucial for diagnosing post-THA functional problems.
• Customized rehabilitation strategies based on identified abnormalities yield significant improvements in function and satisfaction.
