Quad muscles not firing, unable to do leg raise or lift foot from bent sitting position

[mathewvarghese]

You have not mentioned the type and site of injury. Is there any wasting of the Quadriceps muscle ? It looks like that there is a Quadriceps lag . The locking mechanism of the knee joint is not functioning. Hence a detailed clinical examination and evaluation is necessary before coming to final conclusion.

I am your twin..I had a meniscus tear repaired and debridment of plica and fat pad. I had a fall on a concrete block twisted knee. June 2016 was the surgery. I struggled had cortisone and SYNVISC injections no help. Did my PHYSIO took 1 1/2 years to do a leg raise...I still limp and have lots of pain. My leg went weak..Muscle atrophy my leg was straight unable to bend at the beginning. No infection. It's one night mare. How are you doing have you healed. I'm seeing a neurologist he did some tests couldn't find much. I found on my own I have flare ups which I think is CRPS. At night I got restless leg syndrome knee jerk twitching more to it band side and best was burning pain entire knee which woke me up. I could tell it was as all morning I could not get out of bed cause of no energy. I was reactive for Epstein Barr Virus. I still suffer from fatigue...I walk with a cane and use a scooter for distance. I can't sit long my hamstrings cause pain goes towards knee. I've learnt one thing injections don't help me. I do a simple calf exercise with reduces the 10/10 pain immediately...so I don't get no more injections. My knee is very stiff. I do my PHYSIO but when I get worm down I take 1-2-3 weeks off until my energy back. My last flare took 20 days before I was able to do anything. I still don't have a diagnosis for this. It's crippling.
