Objective: To see the effects of posterior femoral condylar osteophytes removal on range of motion in primary total knee arthroplasty.Study Design: Quasi-experimental studyPlace and Duration of Study: Department of Orthopedics, Combined Military Hospital, Rawalpindi Pakistan, from Dec 2020 to Sep 2021.Methodology: We studied 78 patients [18 males (23.0%) and 60 females (76.9%)]. All of these patients were followed for threemonths. The primary outcome was knee range of motion at 03 months following treatment. Following total knee arthroplasty,the knee range of motion was measured using a goniometer. Results: The mean age of the patient was 63.05±4.98 years. The knee range of motion showed that the effect of posteriorosteophyte removal significantly improved at one-month, 2-months, and 3-months of follow-up. At the one-month follow-up,the average knee range of motion was 10.29±3.06 degrees to 95.69±2.87 degrees. At the three-months follow-up, the knee rangeof motion was 0±0.54 degrees to 110.47±3.12 degrees. Conclusion: Total knee arthroplasty aims to improve quality of life by reducing knee pain and improving function. Range ofmotion is an important part of knee function. This study showed that measurements improved at each follow-up. Removing osteophytes in primary knee arthroplasty positively influenced the range of motion.
