In reply to Martin Bagshaw:
Hi Martin,
I had this procedure (arthroscopy and debridement) on my right ankle in early March. I was in a similar situation to you - rarely experiencing acute pain but regular discomfort and stiffness in the ankle. I was advised that without the surgery there was little chance of improvement, so decided to get it done as soon as possible.
The surgery itself went well, and initial recovery was promising. I aggressively followed the prescribed exercises post-op, as I was keen to regain ROM and prevent unnecessary scar tissue. The first three weeks went well and despite catching the foot it a lot – proprioception takes a while to regain - the ankle improved significantly. Unfortunately I sprained the same ankle three weeks post-op, which has put progress back a lot. I was unable to do any rehab exercises for two weeks, and I would say the condition of the ankle is roughly where it was just prior to the sprain. I’m unsure of the long-term prospects of the ankle, and haven’t yet returned to climbing, running etc.
This is obviously a fairly uncommon situation, so take my experience with a pinch of salt. I don’t regret undergoing the procedure and would do so again in the same circumstances. As I understand it, the op is relatively straightforward and low risk. Of course, only you can decide what’s best for you in your circumstances.
If you have any questions feel free to PM me.
