Patellar tendon rupture is a catastrophic complication following total knee arthroplasty (TKA). Though revision TKA has been suspected of being a predisposing factor for the occurrence of patellar tendon rupture, there are few reports on patellar tendon rupture after revision TKA. Here, we present a case of acute patellar tendon rupture that occurred after TKA revision. In the patient, the pate...

Dear Editor-in-Chief, Many techniques have been described for the treatment of cranial cruciate ligament rupture in dogs. The most commonly used of the corrective osteotomies are: tibial plateau levelling osteotomy, tibial tuberosity advancement (TTA), and more recently the Maquet technique has been described (1). Complications from TTA can be divided into major and minor complications. Major c...

Objectives: The quadriceps angle (Q-angle) measures the force vector of pull extensor mechanism knee. A larger Q-angle is thought to be a predisposing factor for patellar dislocation, but previous literature has reported poor reliability and validity clinically measured Q-Angle. In response reliability, new “Standard Q-Angle” (SQA) was developed by Merchant et al. (Merchant 2020) in an attempt ...

background: prevalence of recurrent shoulder dislocation in patients taking tramadol has not been studiedyet so, this study aims to study the recurrent shoulder dislocation following tramadol induced seizure. methods: in this cross-sectional study, 205 patients with recurrent shoulder dislocation complaints (2 or more) referred to shafa orthopedic and iranmehr hospitals tehran, iran, from octob...

BACKGROUND In sum, 1-, 2-, and 4-stranded allografts are used for soft tissue anterior cruciate ligament reconstruction; however, the fixation properties of fixation devices are not well assessed. HYPOTHESIS There are no differences in the biomechanical characteristics of 1 (Achilles)-, 2 (posterior tibialis)-, and 4 (semitendinosus)-stranded allograft tibial fixation. STUDY DESIGN Controll...

The EndoButton is a commonly used device for femoral fixation of anterior cruciate ligament grafts. Complications from its usage remain rare. Incorrect femoral tunnel placement may increase the risk of intra-articular displacement of the EndoButton. We present a case of anterior femoral tunnel placement resulting in intra-articular displacement of the EndoButton after failure. A 24-year-old man...

BACKGROUND Habitual patellar dislocation is not common in clinical practice, but it has a deep impact on the patient's lifestyle and movement. There has been no large case-control study on habitual patellar dislocation, and the management of it is still controversial. The aim of this study was to observe the efficacy of the modified Fulkerson procedure on patients with habitual patellar disloca...
