Patellar Tendon–Trochlear Groove Angle Measurement
Methods: Three PT-TG angle measurements and the PT-TG distance were measured in 82 participants with patellar instability and 100 controls using magnetic resonance imaging (MRI). Measurement landmarks were the line tangent to the posterior femoral condyles, the deepest point of the trochlea, the transepicondylar line, and the patellar tendon center. All measurements were recorded once by 1 exam...
متن کاملPatellar groove replacement in patellar luxation with severe femoro-patellar osteoarthritis.
OBJECTIVE To report a novel method of treating femoro-patellar instability in association with severe femoro-patellar osteoarthritis, by substituting the femoral trochlear with a patellar groove replacement prosthesis. STUDY DESIGN Retrospective case series. METHODS Preoperative lameness was scored from 0-4, and radiographic studies including standard positions for patellar luxation were ob...
متن کاملPatellar instability in Indian population: relevance of tibial tuberosity and trochlear groove distance
INTRODUCTION The tibial tuberosity to trochlear groove (TTTG) distance in the western population is extensively studied through various modalities such as X-rays, computerised tomography and magnetic resonance imaging. However, to our knowledge there is very little or no literature support to indicate that TTTG distance has been studied in the Indian population. METHODS We therefore undertook...
متن کاملValue of the tibial tuberosity-trochlear groove distance in patellar instability in the young athlete.
BACKGROUND A lateralized tibial tubercle may be a relevant anatomic factor in patients with patellar instability and can be used as an indication for a distal realignment procedure. However, parameter values for the tibial tuberosity-trochlear groove (TT-TG) distance in the young patient have not been defined. It also remains to be determined how this parameter contributes to patellar instabili...
متن کاملSingle beam interferometric angle measurement
We present a new application of the Nomarski interferometer, to measure the angular position of a parallel laser beam with interfero-metric precision. In our experimental realization we reach a resolution of 3 × 10 −9 rad (6 × 10 −4 ′′) for 1 kHz bandwidth in a 2 × 10 −2 rad (1 •) range. This alternative to the optical lever technique features absolute calibration, independence of the sensitivi...
