Patient presents with complaints of knee pain, stiffness, and reduced range of motion consistent with knee osteoarthritis.  Onset of symptoms was gradual, reported as approximately six months ago, and exacerbated by weight-bearing activities such as walking, standing, and stair climbing.  Patient denies any specific injury or trauma to the knee.  Pain is described as a dull ache, localized to the medial aspect of the right knee, with occasional sharp pains.  Stiffness is most pronounced in the morning and after periods of inactivity, improving with movement and throughout the day.  Patient reports difficulty with activities of daily living, including dressing and bathing.  Physical examination reveals crepitus upon palpation of the right knee joint, mild swelling, and tenderness along the joint line.  Range of motion is restricted in flexion and extension compared to the contralateral knee.  McMurray's test is negative for meniscal tear.  Radiographic imaging of the right knee demonstrates joint space narrowing, osteophyte formation, and subchondral sclerosis, confirming the diagnosis of osteoarthritis.  Differential diagnosis includes rheumatoid arthritis, gout, and pseudogout.  Assessment:  Right knee osteoarthritis, Kellgren-Lawrence grade 2.  Plan:  Conservative management is recommended, including weight loss counseling, physical therapy for range of motion and strengthening exercises, and over-the-counter analgesics such as ibuprofen or acetaminophen for pain management.  Patient education provided regarding activity modification and joint protection strategies.  Follow-up appointment scheduled in four weeks to assess response to treatment.  If symptoms do not improve, intra-articular corticosteroid injections or viscosupplementation will be considered.  Referral to orthopedics for surgical intervention such as total knee arthroplasty may be warranted if conservative measures fail.  ICD-10 code M17.1 assigned for right knee osteoarthritis.
