bone, joint, and muscle disorders
Tibialis Posterior Tendinosis and Tibialis Posterior Tenosynovitis
Symptoms
Intibialis posterior tendinosis,early on people have occasional pain behind the inner ankle with increased activity. In time, the pain becomes severe, and swelling occurs. Normal standing and walking become more difficult. Standing on the toes is usually painful and may be impossible if the tendon is completely torn. If the tendon tears completely, the foot may suddenly flatten (called arch collapse) and pain may be felt in the sole. Intibialis posterior tenosynovitis,pain typically occurs suddenly and the tendon may feel thick and swollen as it winds around the bump on the inside of the ankle (medial malleolus). In some cases when the tendinosis has been long-standing, the arch of the foot may gradually fall, and the foot will appear flatter. These bony changes can also cause osteoarthritis in some of the bones of the foot and may progress to the ankle.
