TOTAL KNEE ARTHROPLASTY WITH BONE LOSS – CASE REPORT, ANALYSIS, MANAGEMENT, AND LESSONS LEARNED
Main Article Content
Abstract
Bone loss in revision total knee arthroplasty poses significant challenges, especially in cases involving infection and severe defects. We report a 77-year-old female with prior periprosthetic joint infection and extensive bone loss classified as AORI 2B–3 based on radiographs and CT. Revision surgery was performed using a hinged prosthesis with long stems and metal augmentation following thorough debridement. At 3 months, the patient achieved a range of motion of 0°–90°, stable mechanical alignment, and no recurrent infection. The Knee Society Score improved from 42 to 78. This case highlights the effectiveness of high-constraint implants and porous metal augmentation in managing advanced metaphyseal bone loss.
