Complicated Cases of Knee Arthroplasty

Abstract


Experience in treatment of 190 patients (mean age 61 years) with marked (> 15°) knee deformity due to various pathology (idiopathic gonarthrosis, rheumatoid arthritis, posttraumatic gonarthrosis) is presented. In 19 cases revision interventions for aseptic instability of implant were performed. In all cases «Smith & Nephew» RT-PLUS system of either standard or modular modification was used. In 183 (96.3%) cases satisfactory results were noted: steady remission of chronic pain syndrome was achieved, limb axis, joint mobility and weight bearing ability were restored, conditions for early loading and mobilization were provided. All that promoted the improvement of patients’ life quality. Complications included 1 case of periprosthetic fracture, 5 cases of deep purulent inflammation 2 of which required implant removal with creation of arthrodesis in functionally favorable position, and 3 cases of arthrofibrosis. As a whole the achieved results enable to recommend the use of RT-PLUS system in complicated cases of arthroplasty.
