Exercise Recommendations for Adults with Mild Hip Arthritis from Legg-Calvé-Perthes Disease
Adults with mild hip arthritis secondary to Legg-Calvé-Perthes disease should perform a daily individualized exercise program consisting of strengthening exercises for both legs (especially quadriceps and hip girdle muscles), low-impact aerobic activities, and range of motion/stretching exercises, while avoiding high-impact activities that rapidly load the joint. 1
Core Exercise Components
Strengthening Exercises
- Perform sustained isometric exercises for both legs, targeting quadriceps and proximal hip girdle muscles regardless of which hip is affected 1
- Include gluteal strengthening exercises (gluteal squeezes held for 6-7 seconds, repeated 5-7 times, 3-5 times daily) 1
- Quadriceps exercises should include quad sets and short-arc quad sets performed in lying or sitting positions 1
- Start at manageable levels within your capability and gradually increase intensity over several months 1
Aerobic Activity
- Choose low-impact aerobic exercises such as swimming, cycling, walking, aquatic exercise, or Tai Chi 1
- Aquatic exercise in warm water (86°F) is particularly beneficial as buoyancy reduces joint loading while providing resistance for strengthening 1
- Moderate-intensity training (70% of maximal heart rate) for 45 minutes per day, 3 days per week is effective 1
- Avoid high-impact activities like running, trampolining, ball sports, and gymnastics as rapid joint loading may accelerate damage 1, 2
Range of Motion and Stretching
- Perform daily stretching exercises to maintain hip mobility 1
- Range of motion exercises are critical given that Legg-Calvé-Perthes disease commonly results in restricted hip motion 3
- These exercises should be adjunctive to strengthening and aerobic components 1
Exercise Implementation Principles
Pacing and Integration
- Follow a "small amounts often" approach rather than prolonged single sessions 1
- Link exercises to daily activities (before morning shower, before meals, before bed) so they become habitual rather than additional burdens 1
- Perform strengthening exercises 5-7 repetitions, 3-5 times daily at key transition points 1
Supervision and Delivery
- Supervised exercise programs are more effective than unsupervised home programs, often delivered by physical therapists or in group settings 1
- The mode of delivery (individual sessions, group classes, pool facilities) should match your preferences and local availability 1
- Initial professional instruction is essential, but the goal is independent performance in your own environment 1
Joint Protection Strategies
Mechanical Considerations
- Use appropriate comfortable footwear with shock-absorbing properties to minimize joint stress 1
- Consider a walking cane on the contralateral (opposite) side to reduce hip joint loading 1
- Implement home modifications: raised chairs/beds/toilet seats, hand-rails for stairs, walk-in shower instead of bath 1
Activity Modification
- Avoid excessive loading of the affected hip which may accelerate arthritis progression 4
- Swimming, short walks, cycling, and horseback riding can typically be performed without restrictions 2
- Utilitarian activities like walking the dog, mowing the lawn, or playing golf count as beneficial aerobic exercise 1
Weight Management
- If overweight, implement weight loss strategies including increased physical activity, structured meal planning starting with breakfast, and regular self-monitoring 1
- Reduce saturated fat and sugar intake, limit salt, increase fruit and vegetables (at least 5 portions daily), and control portion sizes 1
Critical Caveats
Disease-Specific Considerations
- Adults with Legg-Calvé-Perthes disease frequently develop femoroacetabular impingement, which is associated with pain and poorer functional outcomes 5
- Pain and radiographic arthritis are common long-term sequelae, with 44% showing moderate-to-severe osteoarthritis at 20-year follow-up 5
- The Stulberg classification (hip shape after healing) significantly predicts outcomes, with types III-V having worse prognosis 5
Exercise Tolerance
- While pain should not automatically preclude exercise, use shared decision-making about when to initiate or modify programs 1
- Clinical trials demonstrate that patients with OA pain and functional limitations still achieve improvements with exercise 1
- Never hold your breath during exercises 1
Long-term Monitoring
- Re-evaluate at 4 weeks for pain reduction and improved function 1
- Continue monitoring at 4-6 month intervals 1
- Regular follow-up allows adjustment of the exercise program based on response 1
Vocational Considerations
- If experiencing work-related difficulties, seek vocational rehabilitation counseling about modifying work tasks, hours, or workplace environment 1
