Abstract
Inflammatory arthritis and extra-articular involvement remain characteristic features of the systemic autoimmune disease rheumatoid arthritis (RA). Metatarsophalangeal joints, wrists, shoulders, elbows, hips, knees, and ankles are among the joints that are most commonly infected. The patient in this case report is a 30-year-old woman with a history of deformities in both hands and legs. She approached the hospital for an examination, where she was confirmed with grade 4 RA. As the condition was severe in the bilateral knee joint, she was first managed with total knee replacement of the left side. Due to this, there was pain around the left knee joint, and also, there was a restriction in the range of motion of the knee joint; for this, the patient was advised for physiotherapy. The patient was regularly treated for 15 days. We report that physical therapy following the surgery significantly reduced pain intensity, improved the knee joint's range of motion, and increased the strength of the muscles around the knee.
