Sports Therapy Interventions Following Total Hip Replacement

Area of Science:

• Orthopedics
• Rehabilitation Medicine
• Sports Medicine

Background:

• Osteoarthritis of the hip often necessitates total hip replacement (THR).
• Post-surgical rehabilitation aims to restore function and improve patient outcomes.
• Sport rehabilitation is a structured intervention for reintegration and self-help post-surgery.

Purpose of the Study:

• To evaluate the effects of intensive sport rehabilitation on hip muscle strength, cardiopulmonary endurance, and stance stability.
• To assess functional outcomes one year after total hip replacement (THR).

Main Methods:

• 160 patients undergoing first-time THR were randomized into an intensive sport rehabilitation group or a control group.
• Muscle strength, stance stability, and endurance were measured at baseline, 6, and 12 months post-surgery.
• Primary endpoint: change in hip extensor, abductor, flexor, and adductor strength at 12 months.

Main Results:

• No significant difference in hip muscle strength between groups at 12 months.
• Intervention group reported less pain (WOMAC score) at 1 year (small effect size).
• Improved quality of life in the intervention group at 6 months, but not sustained at 1 year.

Conclusions:

• Intensive sport rehabilitation did not demonstrate significant functional benefits for patients after total hip replacement.
• Positive trends in pain and quality of life were observed, though effects were small and not always sustained.
• Further trials with larger sample sizes are recommended due to a high dropout rate.
