Overview
Hip osteoarthritis is a wear-and-tear type arthritis that affects the hip joint, where the thigh bone meets the pelvis. Over time, the joint cartilage thins and the bone underneath can become thicker and form bony growths, which can irritate the joint and surrounding tissues. This process can cause pain and stiffness, especially when you start moving or after activity. As the joint becomes less comfortable and mobile, muscles around the hip may weaken and walking can feel more difficult.
Symptoms
Pain is usually felt in the groin, front of the hip, or outer hip and often worsens with walking, climbing stairs, getting in and out of a car, or standing for long periods. Many people notice morning stiffness or stiffness after sitting, along with reduced hip range of motion. You may develop a limp to protect the painful side, and nighttime pain can occur as the joint becomes more irritated. Some patients also experience difficulty putting on shoes or socks due to limited motion.
Causes
Hip osteoarthritis typically develops when the joint's cartilage gradually deteriorates due to mechanical stress over years. Prior joint injury, abnormal hip shape, or altered biomechanics can increase load on the hip and speed up degeneration. Inflammation related to cartilage breakdown can further increase pain and stiffness during flare-ups.
Risk Factors
Risk increases with age, and it is more likely if you have a prior hip injury or long-term joint overload from certain activities or jobs. Having excess body weight adds extra stress to the hip joint. Genetics, abnormal hip anatomy such as impingement patterns, and dysplasia can also make hip osteoarthritis more likely. Hip strength and movement patterns can influence symptoms, even when the underlying joint changes are similar.
Prevention
You can reduce risk and slow progression by maintaining a healthy weight and staying physically active with joint-friendly strengthening and range-of-motion work. Low-impact aerobic exercise, hip and core strengthening, and improving movement mechanics can reduce unnecessary stress on the joint. Using supportive footwear, pacing activity, and avoiding repetitive high-impact loading during flare-ups can help. Early treatment when symptoms start can make it easier to preserve mobility and function.
How the Diagnosis Is Evaluated
Clinicians typically diagnose hip osteoarthritis based on your history of pain location, stiffness pattern, activity triggers, and functional limitations. A physical exam helps assess hip range of motion, pain with rotation, strength, and how you walk. X-rays are commonly used to confirm joint-space narrowing and bone changes, but not every test is needed for every patient. If symptoms are unusual or severe, additional imaging such as MRI or ultrasound may be considered.
Nonsurgical Treatment Options
Non-surgical care aims to reduce pain, improve mobility, and help you return to everyday activities safely. Physical therapy often focuses on strengthening the hip abductors and core, improving flexibility, and teaching movement strategies to unload the joint. Weight management, activity modification, and low-impact conditioning can decrease joint stress and flare frequency. Medications may include topical or oral anti-inflammatory drugs (as appropriate), acetaminophen for pain, and short courses of anti-inflammatory medication under clinician guidance. Assistive devices like a cane in the opposite hand and well-fitted footwear can improve walking mechanics. If pain persists, a clinician may offer image-guided corticosteroid injections, and some patients consider hyaluronic acid such as Orthovisc or platelet-rich plasma (PRP); in selected cases, adipose allograft or stem cell injections may be discussed, understanding that evidence varies and results can be unpredictable.
When to Seek Medical Attention
Seek medical attention promptly if you cannot bear weight, have severe or rapidly worsening hip pain, or notice a new deformity after an injury or fall. Get urgent care if you have fever, chills, or a hot swollen joint, because this can suggest infection or another serious problem. Contact a clinician soon if pain wakes you consistently at night, you develop progressive weakness, or you have numbness, bowel or bladder changes, or other neurologic symptoms. If your symptoms are not improving with conservative care, you should be re-evaluated to confirm the diagnosis and adjust treatment.
Frequently Asked Questions
Hip osteoarthritis usually cannot be fully cured, but symptoms often improve significantly with conservative treatment and the right activity and strengthening plan.
You may need to limit high-impact activities during flare-ups and avoid movements that repeatedly trigger deep groin pain, while staying active with low-impact options like cycling, swimming, or walking with pacing.
Many people notice improvement within several weeks, but durable gains typically require consistent exercise and joint management over a few months.
Next Steps
If you have persistent hip pain and stiffness, start with an evaluation to confirm the diagnosis and rule out other causes. Follow a conservative plan that includes strengthening, activity modification, and pain control measures, and reassess your progress with your clinician. Seek care sooner if symptoms worsen or you develop trouble bearing weight.
