MSK: Posterior Cruciate Ligament Tear: Free MSRA Podcast

⚕️FREE MSRA PODCAST –Posterior Cruciate Ligament (PCL) Tear🎧 Your high-yield revision audio for mastering PCLtears — for the MSRA, exams, or on the go. 🧠Key Learning Points📌Definition• Posterior cruciate ligament (PCL) tear = injuryto the main ligament that stabilises the back of the knee, preventing the tibiafrom moving backwards relative to the femur• PCL provides up to95% of posterior knee stability 📌Causes & RiskFactors• Direct blow to the front of the knee (e.g.“dashboard injury” in car crashes)• Hyperextension injuries• Falling hard onto a bent knee• High-impact/contact sports (football, rugby)• Previous PCLinjury increases re-injury riskMnemonic: DHFSA — Dashboard, Hyperextension,Fall (bent knee), Sports, Accidents 📌Pathophysiology• Force exceedsPCL’s tensile strength → partial or complete tear• Posterior tibialdisplacement = loss of knee stability• Hamstrings/gravitypull tibia backwards in absence of PCL 📌Symptoms &Clinical Features• Knee pain, often with swelling and a sensation of instability(“knee might buckle”)• Difficulty bearingweight• Instability especially with walkingdownhill/stairs• May be lessdramatic than ACL tears (often less “pop”) 📌DifferentialDiagnosis• ACL tear• Medial/Lateralcollateral ligament tears (MCL/LCL)• Meniscal tear• Patellardislocation• General kneeinstability• Osteoarthritis (inchronic cases) 📌Diagnosis• Physical exam: – Posterior drawer test (most sensitive) – Posterior sag test (Godfrey’s test)• MRI: gold standard for assessingligament/tissue injuries and grading severity• X-ray: rules out fractures (especially tibialplateau avulsion) 📌Management• Conservative for most isolated, mild/moderatetears: – PRICE/PRICER: Pain relief, Rest, Ice,Compression, Elevation, early Rehabilitation – Physiotherapy: emphasise quadriceps strengthening (quads = key fordynamic stability) – Bracing orcrutches for some injuries• Surgical: – Reserved forsevere/complete tears, multi-ligament injuries, avulsion fractures, orpersistent instability – Procedure = PCLreconstruction (using tendon grafts)Mnemonic: "Quadsfor PCL" — quad strength is vital in rehab! 📌Prognosis &Complications• Good prognosis with early, focused rehab — manyregain full function• Untreated/unstableknees risk chronic pain, instability, and earlyosteoarthritis• Complications: Patellofemoral/medial arthrosis,chronic knee pain• Commitment torehab is crucial for long-term outcome 📎MSRA Resources forPosterior Cruciate Ligament Tear📝 Revision Notes: https://www.passthemsra.com/topic/posterior-cruciate-ligament-tear-revision-notes/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/posterior-cruciate-ligament-tear-accordion-qa-notes/🧠 Flashcards: https://www.passthemsra.com/topic/posterior-cruciate-ligament-tear-flashcards/🚀 Rapid Quiz: https://www.passthemsra.com/topic/posterior-cruciate-ligament-tear-rapid-quiz/🎓 Full Quiz: https://www.passthemsra.com/quizzes/posterior-cruciate-ligament-tear/ #MSRA #PCLTear#PosteriorCruciateLigament #MSRARevisionNotes #MSRAQuiz #MSRAFlashcards#MSRAQandANotes #MSRAAccordions #MSK #KneeInjury #Orthopaedics#MSRAOnlineRevision
