A short-term study of clinical and radiological outcomes of total knee replacement using all polyethylene tibial component: A prospective observational study

Abstract

Osteoarthritis (OA) of bone peripherally is frequently associated with pain, physical disability and worsening quality of life, which in turn leads to a considerable burden on the society and individuals. The surgical management of OA comprises of arthroscopy, high tibial osteotomy (HTO), unicompartmental knee arthroplasty and total knee arthroplasty (TKA). High tibial osteotomy and unicompartmental knee arthroplasty are potential alternatives if only a single compartment is involved with more data supporting unicompartmental knee arthroplasty as a good treatment option in this scenario. To conclude, early tibial component designs were almost uniformly all polyethylene and still continue to dominate the market. The total condylar designs using these tibial components have continued to show greater than 90% survivorship. No statistically significant improvement was seen in the radiological outcomes in patients undergoing All-Polyethylene tibial component at short term follow up. In this study, there was a significant improvement in the Knee society score, WOMAC score and Oxford score post operatively.
