Background : Mobile bearings in total knee arthroplasty reduce wear of polyethelene and mechanical loosening of components. Method : Non-cemented Low Contact Stress (LCS) femoral implant and cemented LCS rotating platform tibial tray and polyethylene insert was used in 100 knees. Pre-operative diagnosis was osteoarthritis (OA) in 85 and rheumatoid arthritis (RA) in 15 knees. Results : Ninetyeight knees were available for follow-up at a mean interval of 38 months. Minimum of 90 flexion was achieved in all the cases. All patients were females with a mean age of 67 years. Non progressive radiolucent lines of 1-2mm were seen in 6 femoral components. Twelve tibial components also showed similar radiolucent lines in 2 or less zones. Knee Society Knee Score improved from 32 to 93 and function score from 47 to 79. Results were good to excellent in 95 knees. There was no case for bearing spin out or revision. Conclusion : Results of this study suggest that the hybrid fixation can reliably provide excellent or good results in selected patients. Key-words: Mobile bearing knee; Arthroplasty; Porocoat; Hybrid.
