I recently saw a patient who suffered a ankle severe sprain wake boarding. The sprain recovered, but the ankle continued to "snap". on closer examination, the snapping sensation was actually the peroneal tendon snapping around the lateral malleolus.
You can see how the tendons (in the image to the left) are held in place by connective tissue. When this connective tissue is stretched sufficiently, it will allow the tendons to "snap" over the lateral malleolus. It really is a snapping sensation and it is often painful. You can almost see this snapping in the following two images.
While is it is possible to treat this condition conservatively, in a cast boot for example, when the tendons snap over the ankle repeatedly, then sadly, surgery is the only option. The post surgical course is pretty much the same as it would be for any ankle surgery - the repair has to heal, then the joints and muscles need to be rehabilitated for the athlete to return to their sport.
It is important to repair this injury though, because the peroneal muscles play a very important role in normal foot mechanics. Peronus longus, for example, crosses over the bottom of the foot and inserts at the base of the big toe, while the brevis attaches on the lateral border of the mid foot at the base of the fifth metatarsal. Both plantar flexion, eversion and plantar flexion with eversion are impacted by this injury.
My patient who suffered the injury had a surgical repair and is back on the water without restriction.
