Clinical information

• M17.11 diagnosis code refers to primary osteoarthritis affecting only the right knee. It develops naturally over time due to joint wear and tear, rather than from an injury or underlying condition.
• Management may begin with conservative treatments such as weight loss to reduce joint pressure, physical therapy to improve strength and flexibility, assistive devices like canes or knee braces for support, and medications like NSAIDs or corticosteroid injections to manage pain and inflammation.
• If symptoms worsen or these methods are no longer effective, surgical options may be considered, including arthroscopy to clean the joint, osteotomy to realign the bones, or partial/total knee replacement to restore joint function.
