Knee Anatomy
| Term | Definition |
|---|---|
| Medial Femoral Condyle | Articulates with medial tibial condyle and is attachment for MCL |
| Lateral Femoral Condyle | Articulates with lateral tibial condyle and is attachment for LCL |
| Tibial Plateau | Flattened superior surface of the tibia |
| Tibial Tuberosity | Distal Attachment of Patellar tendon |
| Medial Meniscus | Cartilage which is more firmly attached to the tibia and more commonly torn |
| Lateral Meniscus | Cartilage which is freely moving in the middle and less commonly torn |
| Anterior Cruciate Ligament | Tissue preventing anterior translation of the tibia; attaches to the anterior border of the tibial plateau |
| Posterior Cruciate Ligament | Tissue Preventing posterior translation of the tibia; attaches to the posterior border of the tibial plateau |
| Lateral Collateral Ligament | Prevents Varus force to the knee; distal attachment is on the fibular head |
| Medial Collateral Ligament | Prevents Valgus force to the knee |
| Hamstrings | Semimembranosis, semitendinosis, biceps femoris; flexes knee |
| Quadriceps | Vastus lateralis, vastus medialis, vastus intermedius, rectus femoris; extends knee |
| Patella | largest sesamoid bone in body |
| "Jumper's knee" | Patellar tendonitis |
| Largest bursa in body (in knee!) | Suprapatellar bursa |
| Chondromalacia | degeneration of articular cartilage of patella; knee cap "snap, crackle & pops" |
| Jobs of the Meniscus | shock absorption, stability/support, distributes forces across knee, protects the ends of the femur and tibia |
| Osgood-Schlatter's Disease | inflammation of tibial tuberosity due to increased tension created by tight patellar tendon/quad tendon |
| Dislocation | bones move out of place and must be manually reduced |
| Subluxation | bones shift out of place and return back into place on their own |
| Knee injury that is a medical emergency | Knee dislocation |
| Angle created by the pull of the quads in the line of the patella; can predispose knee to injury | Q-angle |
| IT Band Syndrome | inflammation of the IT band at the lateral knee |
