Question: I had an motorbike accident on 14th November (55 days back) and had injury on right knee. I had an injury in the same knee from an accident 3 years back. Initially there was pain, swelling, tenderness and knee giving away. I Have done MRI. Findings are :- Ligament -Areas of altered signal intensity visualized as isotense signals on T1WI and hyperintense signals on T2WI/STIR are noted involving posterior cruciate ligament. Posterior cruciate ligament is thickened. It is suggestive of its contusion. Joint - Minimal joint effusion is noted. Bones - Features suggestive of chondromalacia patella are noted. When visited doctor before doing MRI the findings of the doctor was ACL ligament might be torn/near to torn from the earlier injury. But after MRI s findings doctor told to do Isometric & Isotonic quadricep exercise. Wearing a knee brace. Till now I was having pain in the side ward backside of the knee and currently the pain is moving down and currently having pain in the backside just below the knee joint. When walked for around 300 metres 4 days back without knee brace and moving up on stairs the leg was slightly trembling for sometime. Doctor has told to walk normally but I am not getting confidence to walk for long and normally. Getting Confused if I continue walking and do normal activities or take rest. I can fold the knee fully. But when folding the knee on sitting on bed the knee gives a feeling like giving away a bit. When I wake up in the morning i feel pain in the side back of the knee and a stiffness which slowly goes away once i start folding the knee. This happens when i sit on bed for long keeping the leg straight. There is a click sound when I straighten the knee from folded condition. Also my another knee is giving pain, a small click sound and problem when moving up & down stairs. This may be because I am currently giving more pressure to the better knee. Please tell me how serious is the case and what to do now on.

Dear Dr Tayal, Thanks for your helpful reply. I have few things to ask. 1) Have you gone through my MRI report and prescriptions i attached because the Dr told me that his clinical findings and the MRI findings were not matching and i was a bit confused about it. 2) Is it normal for the knee pain to continue after 56 days as per the MRI report. the pain is moving downwards sometimes. 3) Can i continue walking normally for continuous 30 mins or more bcoz i tried some days back and the leg was trembling slightly for some time. 4) My leg is getting stiff and giving pain while folding when i keep my leg straight on the bed for say 30-40 mins or so, and the stiffness & problem goes away once i start folding slowly. Is this normal also? Thank you Ayanjit

Dear Dr Tayal, Thanks for the reply once again. 1 question. Someone(not a doctor) told me that cycling for sometime may be helpful for this kind of injury(PCL ligament injury). I do have pain in the knee and it increases when I do some long activity or give much pressure on the knee. Should i try cycling now or later?. Regards Ayanjit

Dear Dr, One last question. Have tried riding bike for 3 days back. But there is good pain so i left. Today I did the Quad sets more and I tried stretching my leg with small weight 1 ,2 times. But now I am feeling sharp pain in the right side of my knee. The pain is quite intense and sharp and I have never felt this type of pain in last 60 days. Should I have to rest ?? is it because of the exercise? Please advice. Regards Ayanjit
