ACL Tear
An ACL tear is one of the most common knee injuries in athletes. Whether surgical or non-surgical, the path back to sport requires structured rehabilitation focused on strength, movement quality, and sport-specific loading.
Post-surgical return to sport: 9–12 months. Conservative (non-surgical): varies by activity goals.
Hip Flexor Strain
Hip flexor strains respond well to active rehabilitation. The key is progressive loading and addressing the hip mobility and strength deficits that make athletes susceptible — not prolonged rest.
Grade 1: 1–3 weeks. Grade 2: 3–6 weeks. Grade 3: 6–12 weeks or longer depending on severity. Return to full sport requires criteria-based clearance.
Low Back Pain
Low back pain is one of the most common musculoskeletal issues and responds well to physical therapy. Whether acute or recurring, a movement-first approach targets the root cause instead of only relieving symptoms.
Acute: 2–6 weeks. Chronic or recurring: 8–16 weeks. Most patients see relief within 2–3 sessions.
Hip Replacement Recovery
Physical therapy is essential before and after hip replacement surgery. A structured rehab program accelerates recovery, restores full mobility and strength, and helps you return to the activities you love, whether that’s hiking, cycling, or simply moving pain-free.
Early mobility: 1–2 weeks post-op. Daily activities: 6–12 weeks. Sport (hiking, cycling): 3–6 months. Full recovery timeline varies by age, fitness level, and activity goals.
Calf Strain
A calf strain is a partial tear of the gastrocnemius or soleus, common during sprinting, hills, or sudden acceleration. Physical therapy rebuilds strength and push-off power so you can return to running without recurring setbacks.
Grade 1: 1–3 weeks. Grade 2: 3–6 weeks. Grade 3: 6–12+ weeks.
Sciatica
Sciatica causes pain, numbness, or tingling that travels from the low back into the leg. Physical therapy identifies the source and uses targeted mobility and strength work to reduce irritation and help prevent recurrence.
Disc-related acute: 4–8 weeks. Chronic or recurrent: 8–16 weeks. Piriformis-related: 3–6 weeks.
Rehab PT to Performance PT
Consider starting with rehab PT and transitioning to performance PT as you progress.
