Hi - had a hyperextension lateral movement injury to my right knee about 18 months ago playing rugby, pain was instant but I thought it was just meniscus injury (had 2 previous scopes for meniscus tears). Instability when the swelling went down was terrible, very lax to lateral side and very painful on the medial side. Referred to one of the UK's leading knee OS's who diagnosed after MRI and clinical exam that the posterolateral corner was damaged and LCL needed replacing. He specialises in LARS work so I was happy with his suggestion of this rather than graft.
Day 1+2 post surgery were in hospital. OS warned that it is an extremely painful surgery to have due to proximity to peroneal nerve and I struggled with pain control until oxycontin commenced during day 2. Could toe touch weight bare theoretically but honestly the pain was too great at that stage. Came home with both cricket splint and also a custom fitted PCL / LCL post op brace (well worth the £120 it cost pre-op). Cricket brace great for sleeping in but useless for mobilility and the other brace useless for sleeping in but better for mobility!
Days 3-10 - gradually more comfortable for partial weight bearing with elbow crutches, still on strong pain relief though due to the intense pain in my lower leg (screws and tunnel in fibula are the worst part of this surgery).
Day 11 - here I am today, get the stitches out this Friday from the arthroscope wounds on front and top of knee, the main wound (15cm or so on LCL) is subcutaneous stiches so no need for removal.
Will blog how it goes, if anyone has a similar proceedure planned dont hesitate to message me.
