“…In mammals, the evolution of the patellofemoral joint adapted to gait patterns; for instance, in ungulates where the knee never extends, the trochlea and condyles remained totally separated, while in plantigrades the trochlea became flat and in continuity with the condyles. Bipedal gait and full extension of the knee began with hominids, around 4 million years ago, favouring evolution in various ways: valgus orientation of the femur, obliquity of the joint line, extension of the lateral trochlear facet as well as anteriorisation, lateralisation and flattening of the trochlea [22, 38]. The evolution of trochlear morphology and orientation relative to the femoral condyles could thus explain the anatomic variability of the distal femur when considered as a whole.…”

Benefits of using individualised total knee arthroplasty (TKA) with kinematic alignment. With individualised TKA, the trochlea and condyles are designed independently. In the coronal plane (above), the prosthetic trochlear axis (PTA) remains aligned with the quadriceps line of force (QLF) whatever the orientation of the joint line (JL). In the axial plane (below), the prosthetic trochlea (PT) also remains aligned with the native trochlea (NT) whatever the orientation of the posterior condylar line (PCL).

Objective The aim of the present study was to determine physiological reference values for the morphology of the patella and to analyse these parameters according to patella position in healthy knee joints. Material and methods Healthy knee joints of 409 patients (mean age, 52.3 years [± 16.8]) were analysed retrospectively on MRI images for Insall-Salvati index (ISI), sagittal patella thickness (PTS) and patella length (PLS) as well as axial patella thickness (PTA) and patella width (PWA). Differences between patellar diameters were analysed depending on ISI, side, age and gender. Results Mean PTS was 20.1 mm (± 2.4), PLS 44.0 mm (± 4.4), PTA 21.8 mm (± 2.4) and PWA 44.5 mm (± 4.7). Depending on the vertical patellar position (ISI), all patellar parameters (p < 0.01) showed significant differences between patients with a patella alta, norma and baja. In general, a smaller ISI showed higher measured values for the patellar parameters. There were no significant differences for the laterality. Only PTS showed a significant age difference (p = 0.031). All parameters were significantly larger in male compared to female knees (p < 0.001). Conclusion Reference parameters for the patella morphology are reported. Concluding from the results, a relationship between vertical patellar position and patellar morphology seems to exist. This finding should be taken into account in diagnostics and therapy of patella disorders.
