I am 20 wks post-op comminuted medial tib plat fx, I has 3 screws placed...I went to see new os because my knee is "locking up" and Im unable to go into extension w/my gait,(old OS wasnt concerned). New OS said my MRI before surgery states that i had mcl and pcl tears along w/meniscal tear and he thinks that meniscal tear is causing my problem now...Im 31 and was very active before injury...Why did first OS not repair the pcl/mcl and meniscal tears when he placed the hardware...not to mention i had a MUA 7 wks ago and he did not bother scoping me then either....Grateful for any advice
