Biomechanical evaluation of the influence of posterolateral corner structures on cruciate ligaments forces during simulated gait and squatting - Fig 2

Schematic of the knee model with contact conditions and 21 ligament bundle: The anterior cruciate ligament (aACL, pACL) (anterior, a; posterior, p), posterior cruciate ligament (aPCL, pPCL), anterolateral structures (ALS), lateral collateral ligament (LCL), popliteofibular ligament (PFL), medial collateral ligament (aMCL, cMCL, pMCL) (a, anterior; c, central; p, posterior), deep medial collateral ligament (aCM, pCM), posterior capsule (mCAP and lCAP) (m, medial; l, lateral), oblique popliteal ligament (OPL), medial PF ligament (sMPFL, mMPFL, iMPFL) (s, superior; m, middle; i, interior), and lateral PF ligament (sLPFL, mLPFL, iLPFL).
