MSK: Osteoarthritis: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Osteoarthritis (OA)🎧 A high-yield guide to the most common joint disease – perfect for nailing those MSRA questions and managing real-life MSK patients with confidence.🧠 Key Learning Points📌 Definition• A degenerative joint disease involving progressive cartilage loss and joint damage• Most commonly affects knees, hips, hands, and spine📌 Causes & Risk Factors• Age (most significant factor)• Obesity – ↑ mechanical stress• Previous joint injury• Genetics – family history• Occupational overuse or high-impact sports• Female sex, diabetes, gout🧠 Mnemonic: “O-A-GED JOINTS” – Obesity, Age, Genetics, Exercise (repetitive), Deformities, Joint trauma, Osteoporosis, Inflammation, No repair, Time, Sex (female)📌 Pathophysiology• Cartilage degradation triggers inflammation• Formation of osteophytes (bone spurs)• Subchondral sclerosis and cyst formation• Progressive joint space narrowing → pain & stiffness📌 Symptoms• Joint pain (worse with use)• Morning stiffness <30 mins• Reduced range of motion• Crepitus, swelling, joint deformity🧠 Think: “Stiff, Sore, and Stuck”📌 Differential Diagnosis• Rheumatoid arthritis• Gout / Pseudogout• Psoriatic arthritis• Septic arthritis• Referred pain (e.g. from spine)• Meniscal tears, bursitis, AVN📌 Diagnosis• Clinical diagnosis if ≥45y + activity-related pain + no morning stiffness >30 mins• X-ray: LO-S-SLoss of joint spaceOsteophytesSubchondral cystsSubchondral sclerosis• Bloods: to rule out RA, gout, etc.🧠 Memory Tip: “LOSS” X-ray findings📌 Management• Core = Weight loss + Exercise• Paracetamol / topical NSAIDs first line• Oral NSAIDs + PPI if needed• Steroid injections for flares• Physiotherapy + joint supports• Consider joint replacement for severe OA🧠 NICE = Core treatments first → stepwise escalation📌 Complications• Chronic pain, reduced mobility• Joint deformity, muscle wasting• Falls, deconditioning• Psychological impacts (e.g. depression)📌 Prognosis• Chronic but manageable• Outcomes depend on joint involved + treatment adherence• Early intervention = better function📎 More MSRA Resources for Osteoarthritis📝 Revision Notes:https://www.passthemsra.com/topic/osteoarthritis-revision-notes/🧠 Flashcards:https://www.passthemsra.com/topic/osteoarthritis-flashcards/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/osteoarthritis-accordion-qa-notes/🚀 Rapid Quiz:https://www.passthemsra.com/topic/osteoarthritis-rapid-quiz/🎯 Quiz Page:https://www.passthemsra.com/quizzes/osteoarthritis/🎓 Full MSK Course:https://www.passthemsra.com/courses/msk-for-the-msra/#MSRA #MSRARevision #OsteoarthritisMSRA #MSRAFlashcards #MSRAQuiz #MSRAQANotes #MSRAAccordions #MSKforMSRA #MSRAClinicalRevision #PassTheMSRA
