Knee Hyperextension injury causing pain standing up for 3.5 years
My knee hyperextension injury 3.5 years ago pulled my inner distal hamstring tendon. MRI of the knee did not show any noticeable tendon tear in that area. The ATG program did not help. Leg press, prone leg curls, and seated leg curls are extremely dangerous for me and cause compression at the front of the knee and continue to prevent me from standing up without extreme pain at the front of the knee. The pain is only with a straight leg, not a bent one. Heavy Leg extensions, kneeling hamstring curls, and hip thrusts do not activate my symptoms, but do not fix anything. The hamstring tendon can handle any amount of eccentric load during the exercise. However if i go to heavy with eccentrics it causes delayed anterior knee pain. the tendon cannot handle moderately heavy concentric loads and starts twitching. light, 15lb concentric seated curls, which do not cause twitching, cause a delayed anterior knee pain to standing up. The more I decrease the range of motion on the curls, the more stress is put on the hamstring tendon and the worse the leg extension symptoms while standing become. There have been times I went too far and curled too much weight which resulted in extreme guarding this time in the hamstring tendon itself. This issue was fixed by doing 10lb prone eccentric curls. Only 10lb seated concentric curls have given any kind of relief to standing, weight above that just limits my leg extension. Many PTs, Doctors, PhDs I have seen did not have any clue whatsoever of how to fix it and they downplayed my 3.5 year injury. Desperately seeking help.
