🎙️ FREE MSRA PODCAST – Osteoarthritis of the Knee (OA Knee)Essential revision for Musculoskeletal & Orthopaedics on the MSRA🧠 Key Learning Points📌 Definition• Osteoarthritis of the knee is a degenerative joint disease where the cartilage in the knee gradually breaks down, leading to pain, stiffness, swelling, and reduced movement.📌 Causes & Risk Factors• Ageing – most common cause (“wear and tear”)• Obesity – extra weight stresses the knee joint• Previous injury – fractures, ligament injuries• Repetitive stress – jobs or sports that overload the knee• Genetics – family history increases risk• Other medical conditions – e.g. rheumatoid arthritisMnemonic: AOPRGM: Age, Obesity, Previous injury, Repetitive stress, Genetics, Medical conditions📌 Pathophysiology• Cartilage thins and breaks down• Bone spurs (osteophytes) form• Joint lining may become inflamed• Whole joint involvement: cartilage, bone, synovium, ligaments📌 Clinical Features• Pain: worse with activity, better with rest• Stiffness: especially after rest or in the morning• Reduced range of motion• Swelling• Crepitus: grinding/popping sensation• Difficulty climbing stairs or walking long distances📌 Differential Diagnosis• Rheumatoid arthritis• Gout• Meniscal or ligament injuries• Traumatic injuries• Other forms of inflammatory or crystal arthropathy📌 Diagnosis• Clinical evaluation: symptoms and examination• X-ray: joint space narrowing, osteophytes (bone spurs)• MRI: if diagnosis unclear, or to assess soft tissues📌 Management• Lifestyle: weight loss, exercise to strengthen surrounding muscles• Physiotherapy: improve mobility, function• Pain relief: paracetamol, NSAIDs, topical analgesics• Assistive devices: knee braces, walking stick• Injections: corticosteroids for severe symptoms• Surgery: joint replacement (total or partial) in refractory cases📌 Complications & Prognosis• Reduced mobility & quality of life• Chronic pain• Joint deformity• Possible need for joint replacement• Prognosis: Variable, but good management can slow progression and improve function📎 MSRA Revision Resources – Osteoarthritis of the Knee📝 Revision Notes:https://www.passthemsra.com/topic/osteoarthritis-of-the-knee-revision-notes/💬 Accordion Q&A Notes:https://www.passthemsra.com/topic/osteoarthritis-of-the-knee-accordion-qa-notes/🧠 Flashcards:https://www.passthemsra.com/topic/osteoarthritis-of-the-knee-flashcards/🚀 Rapid Quiz:https://www.passthemsra.com/topic/osteoarthritis-of-the-knee-rapid-quiz/🎓 Full Quiz:https://www.passthemsra.com/quizzes/osteoarthritis-of-the-knee/#MSRA #Osteoarthritis #OAKnee #MSK #Orthopaedics #MSRARevisionNotes #MSRAQuiz #MSRAFlashcards #MSRAQandANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment #MSRAOnlineRevision
