It was reported the patient underwent a right initial knee arthroplasty.Subsequently, the patient underwent a revision procedure approximately four years post-implantation due to tibial subsidence of 5-6mm due to possible lack in anterior cortical rim coverage.It was further noted that the tibia was thought to be loose/unstable.Operative reports indicate that the patient has a history of effusion in the knee which is most likely due to rheumatoid arthritis.The patient was also noted to have pain, swelling and discomfort in the right knee and the patient is unable to walk long distances.
