Patient presents with complaints of right knee pain consistent with osteoarthritis.  Symptoms include chronic knee pain, stiffness, and crepitus, exacerbated by weight-bearing activities and prolonged standing.  Onset of symptoms was gradual over the past six months.  Patient reports morning stiffness lasting approximately 15 minutes.  Pain is described as aching and localized to the medial aspect of the right knee, with occasional radiation to the thigh.  Patient denies any history of trauma or acute injury.  Physical examination reveals tenderness to palpation along the medial joint line, reduced range of motion with noted crepitus on flexion and extension, and mild effusion.  No instability or ligamentous laxity was appreciated.  McMurray's test was negative.  Radiographic imaging of the right knee demonstrates joint space narrowing, osteophyte formation, and subchondral sclerosis, confirming the diagnosis of right knee osteoarthritis.  Assessment: Right knee osteoarthritis, Kellgren-Lawrence grade 2.  Plan: Conservative management including weight loss counseling, regular low-impact exercise such as swimming and cycling, and over-the-counter pain relievers such as NSAIDs.  Patient education provided regarding osteoarthritis management and the importance of activity modification.  Follow-up scheduled in 4 weeks to assess response to treatment.  If symptoms persist or worsen, consider intra-articular corticosteroid injection or referral to orthopedics for further evaluation and management options including viscosupplementation or surgical intervention.  ICD-10 code: M17.11.
