Knee joint

The largest and most complicated joint in the body: two condylar joints between the femoral and tibial condyles (with the menisci) and a gliding joint between the patella and femur. The fibula takes no part.

اہم نکات

• Hinge + rotation; patellofemoral gliding.
• MCL flat, attached to the medial meniscus; LCL cordlike, free of the lateral meniscus.
• Locking: femur medially rotates; unlocking: popliteus.
• Suprapatellar bursa communicates with the joint.
• Quadriceps tone = main stabilizer.
• Joint: from mesenchyme between bone ends.
• Synovial cavity forms in the middle layer.
• Synovial membrane: type A (phagocytic) + type B (secretory) cells.
• Joint surfaces: hyaline cartilage, no perichondrium.
