Tibial Tuberosity-Posterior Cruciate Ligament Distance.
نویسندگان
چکیده
When trochlear dysplasia is present, it is difficult to measure the tibial tuberosity to trochlear groove (TT-TG) distance. A new measurement to assess tuberosity position was recently described by Seitlinger et al, which avoids the difficulty of identifying the TG as it references the posterior cruciate ligament (PCL). To evaluate the reproducibility of the Seitlinger et al findings, 42 knees in 41 patients with a documented history of recurrent patellar instability and 84 knees in patients with no history of patellar instability or patellofemoral symptoms were evaluated with magnetic resonance imaging. The TT-PCL distance was increased in the instability group (mean, 21.6 mm) compared with the control group (mean, 19.0 mm). The TT-PCL distance is an independent risk factor for patients with recurrent patellar instability. Its role in surgical planning remains to be determined.

Avulsion fracture of the tibial tuberosity is an uncommon lesion generally seen in adolescents. Intra-articular lesions combined with a tibial tuberosity fracture reported in the literature are; 3 patellar tendon ruptures, 2 anterior cruciate ligament tears, 2 medial collateral ligament tears, 2 medial meniscus tears, one arcuate ligament tear, and one lateral meniscus tear. In our study, both ...

BACKGROUND Cranial cruciate ligament insufficiency is a common orthopaedic problem in canine patients. This cadaveric and radiographic study was performed with the aim of determining the effect of proximal translation of the tibial tuberosity during tibial tuberosity advancement (TTA) on patellar position (PP) and patellar ligament angle (PLA). RESULTS Disarticulated left hind limb specimens ...
