Total Knee Arthroplasty After a Previous Patellectomy: A Case Report With a Six-Month Follow-Up and a Review of the Literature.

Total knee arthroplasty (TKA) is a widely performed surgical intervention for the treatment of knee osteoarthritis. However, various patient-specific factors altering the biomechanics can influence the surgical technique and the postoperative outcomes. In this case report, a patient is presented who was admitted to our hospital with chronic left knee pain caused by osteoarthritis, with a history of patellectomy after a traumatic event 35 years ago. The surgical procedure undertaken, intraoperative findings, and clinical outcomes six months postoperatively are presented in detail. Furthermore, a review of the literature on knee prostheses utilized, and their efficacy in similar cases, is provided.
