Abstract: Total knee arthroplasty (TKA) is one of the commonly performed procedure for osteoarthritis knee, rheumatoid arthritis, post traumatic arthritis etc. with a main goal of providing a pain free, stable and functional joint. Assessment of clinical outcomes should be done by both objective findings and by taking into account the patients point of view and his/her own evaluation of the functional trends of the treated joint. Forgotten Joint Score (FJS) is one such recently developed patient reported outcome measure (PRO), with better discriminatory power. The main aim of our study was to evaluate the patient reported outcomes in our patients who underwent TKA for osteoarthritis knee using FJS system and to analyse the temporal relationship of the outcomes of the time since surgery. Though there are various scoring systems, the “forgotten joint score” system is a disease specific and joint specific scoring system . We concluded that the best scores among our patients was obtained in patients operated 12months and 24months before the conduct of study. Therefore we can conclude that the maximum improvement in functional status of patients can be expected between 6months to 12months after sugery. Age, gender had no affects on the outcomes and the FJS score. Patients with unilateral TKR as well as bilateral TKR both had equally better functional outcomes and FJS scores.
