Hip and knee pain can stem from various origins, and the specific cause can vary among individuals. Common culprits include osteoarthritis, which is a degenerative joint disease affecting these joints and causing pain and inflammation. Traumatic injuries, like fractures and ligament tears, can result in acute pain in the hips and knees. Overuse, strain, or improper body mechanics may lead to overuse injuries, such as tendinitis or bursitis, manifesting as pain in these areas. Muscle imbalances, particularly weak or disproportionate muscle groups surrounding the hip and knee joints, can result in joint instability and discomfort. Other factors like iliotibial band syndrome, hip impingement, labral tears, meniscus tears, sciatica, bursitis, nerve compression, and conditions like rheumatoid arthritis can also contribute to hip and knee pain.
