Knee slide!!

[erinjames]

Hey all! wonder if anyone can shed any light for me..
About 8 weeks ago i was rugby training in the mud and i slipped and managed to do a massive knee slide! didnt feel anything initially but when at home i was getting up from kneeling on the floor and my knee gave way underneath me and i immediately felt sharp pain around the lateral aspect of my knee joint. I developed a big effusion and could not actively fully extend my knee for 14 days afterwards. The pain is around the postero-lateral aspect of the knee, around biceps fem insertion so i initially thought i had damaged my hamstrings. Now 2 months later i still get pain at the very extremes of flexion (ie deep squat) and compression around that area, although the swelling has gone and i can fully extend now without any problems. However If i sitwith my knees flexed for any long period the knee get very stiff and i struggle to extend again! All ligaments are fine, the knee is not locking or clicking but the only conclusion i could come to was that mhen sliding on my knee i had possibly pinched and damaged the posterior area of my meniscus but i really dont know- can anyone help??? thanks!

Sounds like you may well be on the right track. A meniscal injury will cause a slow effusion (swelling) inside the joint over say a 24 hr period.

There are only two major structures (not including a fracture) that would cause a large, rapidly developing effusion. They are the anterior cruciate ligament and the dislocation of the patella. Both could have an impact at end of range flexion of the knee.

It's best to see a good sports physio of sports medicine doctor who can assess and "feel" the range of the knee and try to ascertain what they think is blocking it. Perhaps they might refer you for an MRI.
