What exercises are recommended before hip replacement surgery due to osteoarthritis to promote faster recovery?

Pre-Hip Replacement Exercises to Promote Faster Recovery in Osteoarthritis Patients

Progressive strength training and aerobic exercises performed at least 2 days per week for 8-12 weeks before hip replacement surgery are strongly recommended to improve post-surgical recovery and reduce pain in patients with osteoarthritis. 1

Evidence-Based Exercise Recommendations

Strength Training

• Lower limb strengthening: Focus on hip and quadriceps muscles
  • Perform at moderate to vigorous intensity (60-80% of one repetition maximum)
  • Complete 8-12 repetitions per exercise
  • Exercise at least 2 days per week 1
  • Both dynamic and isometric exercises are beneficial, with dynamic exercises showing stronger evidence

Aerobic Exercise

• Moderate-intensity aerobic training: 30 minutes daily, up to 60 minutes for greater benefit 1
• Options include: Walking, stationary cycling, or aquatic exercises if tolerated

Specific Hip Exercises

• Hip abductor strengthening: Particularly important as these muscles support hip stability 2
• Hip external rotation exercises: Shown to significantly improve range of motion before and after surgery 2
• Quadriceps strengthening: Improves functional outcomes and reduces pain 1

Implementation Strategy

Exercise Progression

1. Begin with supervised sessions: Research shows 12 or more supervised sessions produce better outcomes for pain reduction (ES 0.46) and physical function (ES 0.45) 1
2. Gradually increase intensity: Start with lighter resistance and increase as tolerated
3. Maintain consistency: Exercise program should be maintained for 6-12 weeks before surgery 3

Additional Beneficial Components

• Weight management: If overweight or obese, weight loss programs with explicit goals should be incorporated 1
• Patient education: Combined exercise and education programs improve activity after hip replacement and reduce time to reach functional milestones during hospital stay 4
• Appropriate footwear: Use shoes with proper support and shock absorption 1

Benefits of Pre-Surgical Exercise

Research demonstrates that pre-operative exercise programs for hip osteoarthritis:

• Reduce pain before surgery (SMD = 0.52) 4
• Improve physical function (SMD = 0.47) 4
• Lead to faster achievement of functional milestones after surgery (SMD = 0.50 for first day walking) 4
• Reduce the need for post-operative physical therapy sessions (5.2 vs 6.85 sessions) 5
• Improve independence in basic activities like stair climbing, toilet use, and transfers 5

Common Pitfalls and How to Avoid Them

1. Overexertion: Exercise should not increase pain or swelling

   • Solution: Modify intensity to stay within pain-free range

2. Inconsistency: Sporadic exercise provides minimal benefit

   • Solution: Create a regular schedule and gradually integrate exercises into daily routine

3. Poor technique: Incorrect form can reduce effectiveness and increase injury risk

   • Solution: Begin with supervised sessions to learn proper technique

4. Inadequate progression: Failing to increase difficulty as strength improves

   • Solution: Gradually increase resistance, repetitions, or duration as tolerated

5. Ignoring pain signals: Continuing through significant pain

   • Solution: Distinguish between muscle fatigue (acceptable) and joint pain (signal to modify exercise)

For patients unable to perform the recommended exercise intensity, they should remain as physically active as their abilities and condition allow 1. The evidence clearly shows that customized pre-operative exercise programs are well-tolerated by patients with end-stage hip arthritis and effectively improve early recovery of physical function after total hip arthroplasty 6.
