Hip arthritis results from the breakdown of cartilage within your hip joints, causing hip stiffness and pain that can increase with inactivity, standing, and walking. Although walking can be uncomfortable and difficult with hip arthritis, walking is also incredibly important for maintaining the mobility and strength of your hips.
Chondromalacia patella, also known as runner's knee, is a knee condition that can cause pain and grinding when the knee is flexed. It's due to the breakdown in the cartilage on the undersurface of the kneecap (patella) that causes bones to rub against each other. Overuse (especially from running or cycling), trauma, such as a fracture, or a misalignment of the kneecap and femur can all cause chondromalacia.
While ACL reconstruction with an allograft was associated with a high risk of revision in younger patients, it may be an acceptable choice for older patients who are not athletes, according to a presenter here.
The Achilles tendon connects the calf muscles to the heel bone, also known as the calcaneus. If the Achilles tendon ruptures, a specific test can be done — the Achilles tendon rupture test, also called the Thompson test or calf squeeze test. Since the Achilles tendon is essential for walking and running, a tear necessitates starting treatment as soon as possible.
