BACKGROUND Various surgical techniques to treat posterolateral knee instability have been described. To date, the recommended treatment is an anatomic form of reconstruction in which the 3 key structures of the posterolateral corner (PLC) are addressed: the popliteofibular ligament, the popliteus tendon, and the lateral collateral ligament. PURPOSE/HYPOTHESIS The purpose of this study was to ...

We describe a case of isolated proximal tibiofibular joint dislocation in a 20 years old girl following trauma. Dislocation was reduced through a new and simple reduction technique after failure of classic reduction maneuver. This technique by using isokinetic movements lead to relax the fibular collateral ligament and allow the biceps tendon to snap the proximal end of the fibula back into the...

BACKGROUND/AIM Aggressive benign or malignant tumors in the proximal fibula may require en bloc resection of the fibular head, including the peroneal nerve and lateral collateral ligament. Here, we report the treatment outcomes of 12 patients with aggressive benign or malignant proximal fibula tumors. PATIENTS AND METHODS Four patients with osteosarcoma and 1 patient with Ewing's sarcoma were...

BACKGROUND Consensus has been lacking as to how to reconstruct the posterolateral corner (PLC) of the knee in patients with posterolateral instability. We describe a new reconstructive technique for PLC based on Larson's method, which reflects the physiological load-sharing pattern of the lateral collateral ligament (LCL) and popliteofibular ligament (PFL). FINDINGS Semitendinosus graft is ha...

Knee ligament reconstruction can be performed with autograft or allograft. The use of an has been shown to improve outcomes in primary anterior cruciate for young, active patients, and also revision surgery. A systematic review posterior showed no difference between allograft tissue. There is a paucity data comparing versus fibular collateral posterolateral corner reconstructions, alone combine...

The purpose of this study was to contrast the magnetic resonance imaging appearance of uninjured components of the posterolateral knee with that of injured structures, and to assess the accuracy of magnetic resonance imaging in identifying posterolateral knee complex injuries. Thin-slice coronal oblique T1-weighted images through the entire fibular head were used to identify the posterolateral ...

Snapping biceps femoris tendon (BFT) over the fibular head is an uncommon cause of lateral knee pain, with few case reports in the literature.1–12 Reported causes include anomalous tendon insertion, tears at the tendon insertion site, abnormality of the fibular head, and tendon subluxation despite normal anatomy. When nonoperative management fails, various surgical treatment techniques have bee...

OBJECTIVE To verify the incidence and characterize morphologically the anterolateral ligament of the knee (ALL) in cadaveric samples of the collection of the Laboratory of Anatomy of the Department of Morphology of the Universidade Federal do Espírito Santo. METHODS Dissections and cross sections were performed for mesoscopic analysis of the anterolateral region of 15 knees preserved in 4% fo...

Background: Injuries to the fibular collateral ligament (FCL) seldom occur in isolation and may present with a concomitant injury biceps femoris tendon anterior cruciate (ACL). structures of posterolateral corner (PLC) lead varus rotational instability knee, subjecting ligaments increased forces that result graft failure. Therefore, reconstruction these should be performed concurrently ACL. Ind...

BACKGROUND Increased stability of posterolateral corner knee injuries has been observed clinically after proximal tibial medial opening wedge osteotomies. HYPOTHESIS Static varus and external rotatory stability will be significantly improved in a knee with a grade 3 posterolateral knee injury after a proximal tibial medial opening wedge osteotomy. STUDY DESIGN Controlled laboratory study. ...
