Mild effusion. Ligaments stable. Strength 5/5 throughout. Gait antalgic on the right. Left knee: Unremarkable.
- Investigations: X-ray right knee (standing views) - September 2024 (i-Med): Moderate joint space narrowing in the medial compartment, osteophytes, and subchondral sclerosis. MRI right knee - October 2024 (PRC): Confirms medial compartment osteoarthritis with meniscal degeneration and mild bone marrow oedema.
Discussion and Plan:
- Management plan: Discussed the diagnosis of medial compartment osteoarthritis of the right knee and available treatment options, both conservative and surgical. Patient consented to a trial of conservative management. Non-surgical treatment options include regular physiotherapy focusing on strengthening quadriceps and hamstrings, improving range of motion, and activity modification. Prescribed Celecoxib 200mg daily as a trial of NSAIDs. Educated patient on potential side effects of NSAIDs and importance of taking with food. Patient advised to use ice packs for acute pain and continue with paracetamol as needed. If conservative measures prove insufficient after 4-6 weeks, a corticosteroid injection into the knee joint will be considered. Pre-operative care and surgical options (e.g., knee arthroplasty) were briefly discussed as future considerations if conservative treatment fails. Patient to follow up in 6 weeks or sooner if symptoms worsen significantly. Activity restrictions include avoiding high-impact activities for the next few weeks. Patient's concerns regarding surgical intervention were addressed.
