It was reported that there was revision of lcs implants.Revision due to stiffness, particularly going up and down stairs which was developed postoperatively.This wasn't an issue initially post op but developed over time.The patient underwent debridement and contracture release which increased flexion to 85 degrees but it then stiffened up again to only about 45 degrees of flexion.This was her right knee, no issues with the left knee which notes mentioned had also had a tka.No pain in left or right knee.Sizes in situ from lcs were 2.5 tibia, 10mm insert and standard femur.Initial notes post op from [year] were stable and well-balanced knee but lateral retinacular structures were tight.No wear was observed on the insert.A fracture occurred post revision surgery, this was believed to be caused due to the high bmi.Fracture occurred in the femur above the stem (which couldn't be seen in the x-ray taken), this is believed to have occurred after the torniquet was removed and the leg moved post op.
