Hip conditions encompass various disorders affecting the hip joint, surrounding muscles, tendons, ligaments, and bones. The hip joint is one of the body’s largest weight-bearing joints, consisting of a ball-and-socket structure where the femoral head fits into the acetabulum. This complex joint enables a wide range of motion while supporting body weight during standing, walking, and other activities. Hip conditions can develop due to wear and tear, injury, genetic factors, or underlying medical conditions. In Singapore, hip problems affect approximately 15% of adults over 45, with prevalence increasing with age.
Hip osteoarthritis represents the most common degenerative hip condition, characterised by gradual cartilage breakdown leading to bone-on-bone contact. This condition typically develops over years and primarily affects older adults, though younger individuals with previous hip injuries may develop early-onset arthritis.
