“…The TFL can also exert a lateral force on the patella via connections to the iliotibial band, which is connected to the patella and the lateral patellar retinaculum. 24,30,31 Excessive hip internal rotation and lateral patellar displacement have been linked to conditions such as patellofemoral pain. [40][41][42]46 In addition, atrophy of the GMAX muscle relative to the TFL has been observed in persons with degenerative hip joint pathology.…”

“…Because it also attaches onto to the distal femur and has fibres that connect to the patella, it plays a role in controlling varus and internal rotation of the knee [35], and thus has a role in the mechanism of the pivot-shift [34], as well as ITB tension causing patella lateral tilt and reduced lateral stability [36].…”

Abstract:The paper describes the concepts of primary and secondary restraints to knee joint stability, and explains systematically how the tibia is stabilised against translational forces and rotational torques in different directions and axes, and how those vary across the arc of flexion-extension. It also shows how the menisci act to stabilise the knee, in addition to load-carrying across the joint. It compares the properties of the natural stabilising structures with the strength and stiffness of autogenous tissue grafts, and relates those strengths to the strength of graft fixation devices. A good understanding of the biomechanical behaviour of these various structures in the knee will help the surgeon in the assessment and treatment of single and multi-ligament injuries.Response to Reviewers: 1.

“…The ITB was also loaded in accordance with earlier studies 16,17 that showed that it affects patellar tracking. 17,31 Alterations in patellar tracking may cause abnormal retinacular tensions, and the extensor retinaculum contributes significantly to patellar stability. 15,18,32 Malrotation of the femoral component following TKR causes significant differences in length change patterns within the principal structures of the retinaculum.…”

Malrotation of the femoral component may cause patellofemoral complications after total knee replacement (TKR). We hypothesized that femoral component malrotation would cause excessive lengthening of the retinacula. Retinacular length changes were measured by threading fine sutures along them and attaching these to the patella and to displacement transducers. The knee post-TKR was flexed-extended while the quadriceps were tensed, then the measurements repeated after rotating the femoral component 58 internally and then 58 externally. Internal rotation shortened the medial patellofemoral ligament (MPFL) significantly from 1008 to 08 extension. External rotation lengthened the MPFL significantly from 908 to 08 extension. The transverse fibers of the lateral retinaculum showed no significant differences. The MPFL attaches directly from bone to bone, so it was lengthened directly by movement of the trochlea and patella, whereas the deep transverse fibers of the lateral retinaculum attach to the mobile iliotibial tract, so they were not lengthened directly. ß
