BACKGROUND Patients from rural background in India have high demands for flexion at knee because many depend on kneeling and squatting in day to day activities post total knee replacement. We wanted to study the amount of flexion achieved in cases of Total Knee Arthroplasty using Rotating Platform (PS 150) High Flexion Knee. METHODS The present study is a prospective analysis of grade III to grade lV osteoarthritis, and rheumatoid arthritis presenting to our hospital from July 2016 to July 2017, and treated with Total Knee Arthroplasty using Rotating Platform (PS 150) High Flexion Knee. The present study included 30 pts. (39 knees) operated with rotating platform high flexion knee, total knee arthroplasty and followed up for a period of 1 year. RESULTS As graded with the knee society score, finally, 36 of the total knees (92.31) had excellent outcome, and 2 knees had good outcome. There was one knee which required revision total knee arthroplasty as a two-stage procedure, because of the deep infection. CONCLUSIONS Rotating Platform (PS 150) High Flexion Knee is intellectually interesting option in younger and active patients. Hyperflexion is easier in these patients and hence useful in Asian population for social custom.
