BACKGROUND Historically, a lateral retinacular release was one of the primary surgical interventions used to treat lateral patellar instability. However, disruption of the lateral structures during this procedure has been associated with medial instability of the patella. HYPOTHESIS We hypothesize that good to excellent outcomes can be achieved at midterm follow-up after lateral patellotibial...

BACKGROUND Options for surgical correction of acquired flexible flatfoot deformity involve bone and soft-tissue reconstruction. We used an advanced cadaver model to evaluate the ability of key surgical procedures to correct the deformity and to resist subsequent loss of correction. METHODS Stage-IIB flatfoot deformity was created in ten cadaver feet through ligament sectioning and repetitive ...

Lateral tissue releases in valgus total knee arthroplasty frequently produce asymmetric flexion-extension gaps and ligamentous instability. This study compared 2 lateral-release sequences and quantified the effects of sequential lateral capsular ligamentous structure release. One knee from 7 paired specimens was released according to a 4-step sequence: posterior cruciate ligament (PCL), ibiotib...

We present the case of an 80-year-old man with a tumor recurrence on his right arm 6 years after initial treatment. The lateral aspect of the elbow joint, involving overlaying skin, muscles, tendons, joint capsule, lateral collateral ligament complex, the lateral 1/3 of the capitellum, and lateral epicondyle of humerus were excised in the tumor resection. Intraoperative assessment revealed mult...

Background: The role of magnetic resonance (MR) imaging in patients with lateral ankle instability remains unclear. This study reports the MR findings in patients with asymptomatic ankles.Materials and Methods: A total of 14 ankles in 11 asymptomatic patients were evaluated using 3.0 Tesla MR scanners. Imaging planes included axial PD and T2 weighted sequences, coronal fatsaturated PD fast spin...

Introduction Complete or partial ossification of the pterygospinous ligament that connects the posterior border of the lateral pterygoid plate to the spine of the sphenoid bone occurs in 1-31.2% of people [1,2]. The ossified pterygospinous ligament is detected on the lateral or medial side or crossing over the foramen ovale on the radiographs of the dry scull in the axial projection with the be...

PURPOSE The purpose of this study was to evaluate the relative importance of the different static stabilizers of the posterolateral corner of the knee in cadavers. METHODS Tests were performed with the application of a varus and external rotation force to the knee in extension at 30 and 60 degrees of flexion using 10 cadaver knees. The forces were applied initially to an intact knee and then ...

Description of the surgical anatomy of the superficial fascia of the face must include its deep attachments. These attachments have been mapped out for the forehead, temple, and cheek as retaining ligaments. The deep attachments of the orbicularis oculi of the lower lid and lateral canthus have long been recognized in canthopexy surgery but have yet to be properly defined. Six fresh cadavers we...

Posterolateral rotatory instability (PLRI) of the elbow is the most common type of chronic elbow instability and is principally due to lateral ulnar collateral ligament injury. We describe a novel surgical technique for the treatment of PLRI using the Surgilig/ LockDown. Using this tensioned double-braided polyester synthetic ligament to reconstruct the lateral ulnar collateral ligament it is p...

The meniscofibular ligament is an anatomically defined ligament of the knee in humans. However, there are no data regarding the prognosis following injury to this ligament. Our case was a 42-year-old man who presented at our clinic with pain of the lateral side of his left knee. MRI of his left knee revealed the rupture of the meniscofibular ligament. The mechanism of injury was consistent with...
