Hip osteoarthritis
Gradual degeneration of the joint's cartilage, most common in older adults, producing groin pain, stiffness, and reduced range of motion that typically worsens over months to years.
Hip · The hip is a deep, stable ball-and-socket joint that bears several times body weight during walking and running, making it a common site of both overuse pain and degenerative change.
Hip conditions span degenerative joint disease, tendon overuse at the outer and front of the hip, labral injury, and muscle strain, with the relevant condition often varying by age and activity level.
Osteoarthritis becomes progressively more common with age, while tendon and labral conditions are seen across a wider age range, particularly among physically active individuals.
Gradual degeneration of the joint's cartilage, most common in older adults, producing groin pain, stiffness, and reduced range of motion that typically worsens over months to years.
Pain at the outer hip related to irritation of the gluteal tendons or nearby bursa, often aggravated by lying on the affected side or climbing stairs.
Abnormal contact between the femoral head and socket during certain movements, related to bone shape variation, sometimes contributing to groin pain in younger, active individuals.
Damage to the cartilage ring deepening the hip socket, which can produce deep groin pain, clicking, or a sense of catching, particularly with pivoting movements.
Irritation of the hip flexor tendon at the front of the hip, common in sports involving repetitive kicking or sprinting.
Overuse-related irritation of the hamstring tendon where it attaches near the base of the pelvis, producing deep buttock pain often aggravated by sitting or running.
Because hip and groin pain can arise from the joint, tendons, or referred sources such as the lower back, a structured assessment is important to direct treatment toward the actual source of symptoms.
The knee is the body's largest joint and one of its most frequently injured, relying on ligaments and surrounding muscles rather than bony shape for stability.
Pain frequency 65The anterior cruciate ligament stabilizes the knee against pivoting and forward-sliding forces, and its rupture is one of the most studied and rehabilitation-intensive sports injuries.
Pain frequency 50The ankle and foot absorb and redirect the full force of body weight with every step, making sprains and overuse injuries among the most common in sport and daily life.
