How to Know I Have an Achilles Tendon Injury
A thorough evaluation after an Achilles tendon rupture is important. The diagnosis can usually be made clinically, without the use of advanced imaging modalities such as MRI. The patient usually has a palpable gap at the area of the Achilles tendon rupture. While ruptures are usually located 2-3 inches above the Achilles attachment to the heel bone, the rupture occasionally tears off at its attachment to the heel bone (calcaneus) – termed an insertional rupture. A Thompson test is utilized to confirm the diagnosis of an Achilles tendon rupture. The test is done by laying a patient on his or her belly and squeezing the calf. If the tendon is intact, there is brisk downward movement (plantar flexion) of the foot. On the other hand, if the tendon is ruptured, there is no motion of the foot when the calf muscle is squeezed. X-rays are sometimes required to confirm that there has been no avulsion, or bone being pulled off of the heel bone.
How to Treat an Achilles Rupture
Once the diagnosis has been confirmed as an acute rupture of the tendon in its midsubstance, treatment can be determined. Both operative and nonoperative solutions are possible. In general, younger, healthy, and more athletic individuals are typically treated surgically while older, unhealthy, and less active patients are treated non-operatively. Surgical treatment involves making a small incision and repairing the tendon with suture, and non-operative treatment places a patient in a cast with the foot in a downward position. Both forms of treatment can be effective, but surgery results in earlier resumption of weight bearing, motion, and ability to ambulate and gain strength. Surgical patients return to work or sports participation with less risk of re-rupture. Non-operative treatment, on the other hand, has less risk of infection and the other complications related to surgery yet still produces a good clinical outcome at 1 year that is comparable to that of surgical repair. The single biggest risk with non-operative treatment is that of a re-rupture, which is 2-3 times that of an Achilles tendon treated surgically. The best treatment option is determined by an open discussion with the patient about individual recovery goals, as well as risks and benefits of each procedure.
