| Re: Ankle Ligament Reconstruction
Lisa:
I am kind of obsessive and did a lot of reading and researching prior to my surgery. There are a number of different surgical techniques to repair ankle ligaments. They surgeries fall into two camps: repairative and reconstructive.
I had a repairative surgery (Modified Brostrom). WIth this surgery the ATFL and CFL (two main lateral ligaments) are cut then reattached shorter to the fibula. The extensor recalcanium (sp?) which is ligament like tissue that holds the ligaments tight to the foot is moved up into the ankle joint and attached to the fibula. This gives greater support. No tendons are used to reconstruct the ankle. With a repair surgery the anatomy basically stays the same - its just tighter. Near full range of motion is acheived in the future and you can go back to an almost normal ankle. Long-term studies show 85% -90% of patients report "excellent" outcomes. In a small number of cases instability and sprains continue and another repair surgery is necessary or often a reconstructive surgery will be done. The Brostrom procedure has a quicker recovery time.
Reconstructive surgery involves harvesting a tendon to tighten the ankle ligaments. The most common is Christman-Snook which harvests (usually) part of the peroneus brevis tendon and wraps it around the fibula and attaches it. No repair of the ligaments is made. The tendon will provide the support. Reconstructive surgery is more invasive - the incision is bigger. Recovery is a bit longer (a few more weeks non-weight bearing, move from a cast/boot is a few weeks longer) and likely is more painful. After recovery the ankle is tighter and a full range of motion cannot be achieved again. There is less chance of further instability or sprains (in return for less range of motion). From what I read and what my OS told me, Christman-Snook is usually used only if (a) the ligaments are too damaged to do a Brostrom, or (b) the patient is in a profession where increased tightness or stability is needed (e.g. football linemen), (c) the patient is heavy, (d) a prior Brostrom failed.
In my case I had an MRI and an arthrscopic debridement prior to my ligament surgery so the OS knew that the ligaments could be repaired. Its difficult to tell from just an examination. My OS said that I had one of the looser ankles he has seen, yet was able to repair the ligaments rather than do a reconstructive procedure. Without an MRI or prior look often the Dr. won't know which type of surgery until they see the ligaments. My OS (who is a foot and ankle specialist) said that he is able to do a Brostrom in the vast majority of cases.
So far (8 weeks after surgery) I am really happy with my surgery. Prior to the surgery it felt as if my ankle just didn't fit together right. It feels much better now. PT is going great. My limp is getting less and less each day. I am swimming, doing light yoga and using the exercise bike. My range of motion is getting close to my left ankle. I am getting pretty excited about returning to normal life. Realize though, especially on top of your prior fracture, that your injured ankle will never be like the other one.
Good luck. Keep us informed.
