I want to let you read a synopsis from the British Medical Journal that I pulled off a google search here in VA. One case report does not mean a lot other than yes the repair is done but you have to find the specialist that does it.
OK so it won' let me copy and paste. Look up Repair of rectus femoris ligament with LARS ligament by Miss Clare Taylor who is 1 of the authors and can be contacted at [email protected]. They have done it with decent outcomes if you believe 1 case study.
There are a lot of reports available but this one seems to be in your neck of the woods. Let me know if this is productive for you
