Hip osteoarthritis is the most common diagnosis I give patients who come in describing a gradual ache in the groin, stiffness that takes 20 minutes to shake off in the morning, and a hip that has quietly started limiting what they're willing to do. It often arrives slowly enough that people assume it's just aging — that tightening up and slowing down is the natural next step.It isn't. And physical therapy, started at the right time with the right approach, changes the trajectory of hip OA in ways that most patients don't realize are available to them.
What Is Hip Osteoarthritis?
Hip osteoarthritis (OA) is a degenerative joint disease involving the progressive loss of articular cartilage within the hip joint, accompanied by subchondral bone changes, osteophyte formation, and low-grade synovial inflammation. The hip joint is a ball-and-socket formed by the femoral head and acetabulum, and it depends on healthy cartilage to distribute load evenly and allow smooth, pain-free movement across its full range. As that cartilage degrades, the joint loses its capacity to tolerate load without triggering pain and protective muscle guarding. Over time, this creates a vicious cycle: pain inhibits movement, reduced movement accelerates disuse, disuse leads to further strength and mobility loss, which in turn increases joint stress and pain.
The classic clinical picture of hip OA includes:
- Groin pain that may radiate to the anterior thigh or knee
- Morning stiffness lasting less than 60 minutes (longer stiffness suggests inflammatory arthritis)
- Restricted hip range of motion, particularly internal rotation and flexion
- Pain with prolonged weight-bearing (walking, standing, stairs) that improves with rest
- Gradual onset over months to years, often without a specific injury event
Hip OA is confirmed on clinical exam; X-ray findings (joint space narrowing, osteophytes) are used to grade severity but should always be interpreted alongside symptoms. Imaging changes do not linearly predict pain or function, as many patients with significant radiographic OA are minimally symptomatic, and vice versa.
Does Physical Therapy Actually Work for Hip OA?
Yes. This is one of the better-supported conclusions in musculoskeletal rehabilitation. A 2023 systematic review and cumulative meta-analysis by Teirlinck and colleagues, published in Osteoarthritis and Cartilage Open, analyzed randomized controlled trials evaluating supervised exercise therapy for hip OA versus no treatment or usual care. The review found that exercise therapy produces clinically worthwhile improvements in both pain and function at the end of treatment, meeting or exceeding the pre-specified threshold for clinical meaningfulness (SMD ≤ −0.37). This finding was stable across cumulative analysis, meaning that adding new trials over time has not changed the conclusion: supervised exercise works.The most current professional guideline from the 2025 APTA Clinical Practice Guideline on Hip Osteoarthritis (Journal of Orthopaedic & Sports Physical Therapy, September 2025) synthesizes RCT-level evidence from 2016 through August 2025 and recommends a combination of supervised therapeutic exercise and manual therapy as first-line, evidence-based interventions for hip OA. This is the most up-to-date clinical standard physical therapists are expected to practice. Exercise does more than reduce pain. It improves:
- Hip flexor and abductor strength, reducing compressive joint loading
- Neuromuscular control and proprioception,which deteriorate with OA
- Gait mechanics, reducing asymmetrical loading patterns that accelerate degeneration
- Functional performance on tasks like the 30-second chair stand and timed up-and-go
- Quality of life and psychological wellbeing, which are significantly affected by chronic joint pain
What About Injections and Surgery?
Corticosteroid injections can provide short-term pain relief and are sometimes useful as an adjunct to enable participation in exercise but they are not a good long term primary treatment strategy. The 2023 AAOS Clinical Practice Guideline on Hip OA advises against relying on it as a standalone management approach. Hyaluronic acid (HA) injections are not recommended for hip OA. Five high-quality RCTs show no improvement in pain or function compared to placebo. The AAOS guideline rates this a strong recommendation against use. Total hip arthroplasty (THA) is an excellent procedure with strong outcomes for end-stage hip OA. The goal of physical therapy is not to prevent surgery in patients who genuinely need it, it is to maximize function and quality of life first, and to ensure that patients who do proceed to surgery are as strong and mobile as possible going in (which significantly improves post-operative outcomes). For patients who are not yet at end-stage OA, the right question is not "surgery or PT?" — it is "how well can we optimize this hip with conservative management before considering surgery?" For many patients, the honest answer is: very well.
What Physical Therapy for Hip OA Looks Like at OSO
No two presentations of hip OA are identical. A 45-year-old runner with moderate OA and excellent baseline strength is a different clinical picture from a 62-year-old who has been avoiding the stairs for two years. What we do is consistent thougth. We assess your current capacity, identify the gaps, and build a progressive program around your specific presentation and goals.
Phase 1: Restore Baseline Motion and Calm the Joint : If you're presenting in a flare or with significant movement restrictions, we begin with manual therapy techniques (hip joint mobilization, soft tissue work around the hip flexors and external rotators) combined with low-load exercise in pain-free ranges. The goal is to restore enough movement and reduce enough pain that we can begin meaningful strengthening.
Phase 2: Progressive Strength Loading : This is where the real work happens and where most patients are undertreated in standard clinic settings. Hip and lumbopelvic strengthening (particularly of the gluteus medius, gluteus maximus, hip external rotators, and quadriceps) reduces the compressive and shear forces acting on the joint during walking, running, and lifting. We treat this like a structured training block, not a set of "exercises to do at home."For weightlifters and runners specifically, we analyze your mechanics under load including your squat pattern, your deadlift setup, your running gait and identify the compensations that are overloading your hip. We then correct those patterns systematically, which often reduces pain faster than any modality.
Phase 3: Functional Integration and Long-Term Management : Hip OA is a chronic condition. Our goal is to build the habits, strength, and self-management skills that keep you moving well for the long term. We address return to sport, return to full training, and for patients who do elect THA, we prepare you physically for surgery and guide your post-operative rehabilitation.
Practical Guidance: What to Avoid and What to Keep Doing
One of the most common mistakes I see with hip OA patients is the belief that pain with activity means the activity is causing damage. In most cases, it does not. Graded, supervised exercise is safe for hip OA and essential for managing it. Loading the joint, within appropriate limits, stimulates the surrounding musculature, preserves bone density, and maintains cartilage nutrition through synovial fluid circulation.
Avoid extended periods of rest or inactivity (accelerates deconditioning and muscle loss). Avoid High-impact activities in acute flares without modification. Stop Believing that an X-ray showing "bone-on-bone" means exercise is no longer possible. Keep walking, swimming, and cycling. THey can be excellent low-impact options for maintaining joint mobility. Try Progressive resistance training. When properly supervised, this is beneficial, not harmful. Try working with your PT on gait mechanics if your walking pattern has changed
Frequently Asked Questions
Q: My X-ray shows bone-on-bone. Is it too late for physical therapy?
A: Not necessarily. The relationship between radiographic severity and functional limitation is weaker than most people assume. Many patients with advanced imaging findings respond meaningfully to a structured exercise program. The key question is your functional presentation — how much strength you have, how much motion is remaining, and what your goals are. We can give you an honest assessment.
Q: How long before I notice improvement?
A: Research suggests that exercise benefits for hip OA peak around 8 weeks and are most pronounced in patients who are younger, have not yet been listed for joint replacement, and who complete a supervised program. Most of our patients notice meaningful change within 4–6 weeks of consistent work.
Q: Should I be doing anything differently at home?
A: Yes, and we will prescribe it specifically. Home exercise programs are a core part of our protocols for OA — but they need to be appropriately loaded and progressed. Generic "hip strengthening" exercises from a handout are not equivalent to a supervised, progressive program.
Q: Do you work with patients who have already had one hip replaced and are managing the other side?
A: Absolutely. This is a common scenario, and post-THA rehabilitation and management of the contralateral hip often happen concurrently.
