Patient presents with complaints of chronic right knee pain, stiffness, and functional limitation, consistent with severe osteoarthritis.  Symptoms include pain exacerbated by weight-bearing activities, crepitus, limited range of motion, and morning stiffness lasting greater than 30 minutes.  Conservative treatments such as physical therapy, NSAIDs, and viscosupplementation have failed to provide adequate relief.  Radiographic imaging reveals significant joint space narrowing, osteophyte formation, and subchondral sclerosis in the right knee, confirming the diagnosis of osteoarthritis.  After discussing risks and benefits, the patient elected to proceed with total right knee arthroplasty.  The surgical plan includes right total knee replacement using a cemented prosthesis.  Preoperative assessment includes medical history review, physical examination, laboratory studies including complete blood count and coagulation profile, and electrocardiogram.  Patient education regarding postoperative care, including pain management, physical therapy, and potential complications such as infection, deep vein thrombosis, and prosthetic loosening, has been provided.  The patient understands the procedure and provides informed consent.  ICD-10 code M17.1 (primary osteoarthritis, right knee) and CPT code 27447 (total knee arthroplasty) are applicable.
