Long term outcome of total knee replacement in patients with osteoarthritis a prospective observational study

Abstract

Osteoarthritis is not an immediate lethal disease by itself but has led to rise in global years lived with disability. Over the past one decade the indication for knee replacement has increased tremendously. Cases of arthritis who have undergone total knee replacement (TKR) in past one decade were collected from the medical record department and were studied thoroughly on the age, gender, along with its association with other diseases to find out its risk factors. This is primarily a record-based study was carried out at Department of Orthopedic Surgery, BSMMU, Dhaka, Bangladesh from January 2022 to December 2023. Cases were taken from the medical record department. A total of 146 cases were studied. Each of the cases were studied in terms of age, gender, type of deformity, as well the associated co-morbid conditions to know the significant risk factors. Statistical analysis was done to find if there is any significant association between the above parameters and osteoarthritis (OA). The commonest indication for TKR was found to beOA. There was a strong positive correlation between increased number of cases and rising year trend (r 0.934). A strong positive correlation was also found between - (1) Increase in OA cases and female sex (r 0.998) and male sex (r 0.9822). (2) Increase number of OA cases with age (r 0.994). (3) OA and varus deformity (r 0.991, p
