Treatment of an Adductor Longus Tendon Injury
An adductor longus injury occurs when there is a simultaneous contraction of the oblique muscles and the adductor muscles. The adductor muscles are much stronger than the oblique muscles, so in this tug-of-war the oblique muscles usually tear first. Occasionally the adductor longus tendon is injured. The adductor longus has a poor blood supply. The tendon also has a very narrow attachment to the pubic bone. Because of these factors, even a minor injury to the adductor longus tendon often will not heal, resulting in chronic pain. On physical examination there is pain at the origin of the adductor longus tendon that is aggravated by active adduction of the hip against resistance. Sometimes the pain resolves with a steroid injection. If injections fail, then surgery is very effective.
The tendon is released off of the bone and then reattached. There is no loss of strength. Range of motion is often improved. The reconstruction can be done at the same time as repair of the oblique muscles.
