Hello ACL club
I've no experience of Prof Mackay's internal brace but have read up on it in the past. I don't know if it applies to long-standing injuries with a total rupture - I assume if you leave it too long there's no way the frayed and retracted ends can bridge that gap? (But I'd be interested to know the answer). I don't think you can be referred on the NHS to a surgeon of your choice in Scotland? At least not in my NHS area.
Here's my story for what it's worth. It is possible to live very well with no ACL - I did for 10 years, climbing, hill running, mountain marathons, orienteering etc. It took a good year of hard rehab to recover (lots of strengthening of surrounding muscles, balance work etc). Confidence takes time to fully come back too but I got there then never really thought about it other than "wow, I'm doing this without an ACL" sometimes when running down hills. It stayed entirely stable all that time (though looking back I could have run better down hills with an ACL and I didn't do any pivot sports seriously or regularly).
I'm about to have ACL repair though, following a big meniscus tear which locked my knee and needed cutting out last year. It didn't take much to do this either - just a slight/careful jump down a step in a path, no bad landing, no fall. The loss of the meniscus left my knee not stable enough to do the above (the meniscus plays a role in stability/congruity of bones as well as shock-absorbing). As meniscus does deteriorate with age and I'm nearly 50 I can't say the tear was all to do with the lack of ACL but I did put my knee through a lot considering its vulnerability and imagine it did suffer more than for someone with an ACL, even if I wasn't aware of any instability. (I think research does show a high percentage of meniscal tears as time elapses in unrepaired ACL knees). I have also got some painful wear in my right knee and maybe this has been caused by it taking more than its fair share of the load so that's also worth considering if you do a lot of hill stuff, carrying etc.
Every case is different and the decision to repair or not is not always easy to make. If ball sports had been important to me I am sure I would have had the ACL repair at the time. Now it boils down to what someone said to me more recently "is it stopping you doing what you want to do?" and, having gone through diligent rehab after last year's incident, I have still got regular instability and I can't safely do the stuff I want to do so that's why I'm belatedly having the op.
The key thing is patience (easier said than done) - rehab and time are really an amazing healer both for function and pain, whether you go down a surgical route immediately or otherwise. And whether you have surgery or not (and whether you have an ACL or not!) it's vital to keep your quads and hamstrings strong and balanced to prevent injury. Best of luck!
