INTRODUCTION Lateral instability following total knee arthroplasty (TKA) is a rare condition with limited report of treatment options. The objective of this case presentation is to demonstrate the outcomes of different surgical procedures performed in a single patient with lateral collateral ligament (LCL) deficiency. CASE PRESENTATION We present a case of chronic lateral instability due to L...

Posterolateral instability (PLI) is common with posterior cruciate ligament tears and is less common with anterior cruciate ligament tears, and isolated PLI is rare. There are varying degrees of PLI with respect to pathologic external tibial rotation, and varus laxity. Surgical treatment of PLI must address all components of the PLI (popliteus tendon, popliteofibular ligament, lateral collatera...

BACKGROUND There are little data on the incidence and patterns of injuries seen on magnetic resonance imaging (MRI) in acute inversion ankle sprains. This study may help in the understanding of the pathomechanics, natural history, and outcomes of this common injury. STUDY DESIGN Case series; Level of evidence, 4. METHODS From June 2011 to June 2013, a total of 64 consecutive patients had MR...

BACKGROUND Lateral ankle ligament injuries rank among the most frequently observed athletic injuries, requiring repair or reconstruction when indicated. However, there is a lack of quantitative data detailing the ligament attachment sites on standard radiographic views. PURPOSE To quantitatively describe the anatomic attachment sites of the anterior talofibular ligament (ATFL), calcaneofibula...

Tears to the lateral glenohumeral ligament appear to be uncommon in dogs. Two Labrador Retrievers were arthroscopically diagnosed with lateral glenohumeral ligament tears of the shoulder. Both cases failed to respond to conservative management. Surgical stabilisation of the lateral aspect of the shoulder joint was achieved using an arthroscopically placed suture using a hanging limb technique. ...

OBJECTIVE Knee ligament injuries frequently cause devastating impairment to the injured. In car-pedestrian impact accidents, lateral-medial shear displacement is one of principal mechanisms of knee ligament injuries. The current study aims to investigate injury thresholds of knee ligaments under lateral-medial shear loading to improve pedestrian safety. METHODS Ten isolated human knee joints ...

Controversy exists in the literature as to the precise anatomical location of the lateral canthal ligament. The ligament is a 3 mm-wide, two-tailed band; its average length is approximately 13 mm, while the width of the rima palpebralis is about 26 mm. The authors evaluated three different groups to pinpoint the anatomical position of the ligament's attachment to the lateral orbital wall, and t...

Thirty cadaveric knees were dissected to obtain a detailed understanding of the anatomic structures of the posterolateral aspect of the knee, and a dependable surgical approach to evaluate injuries to these structures was developed and used on 71 consecutive patients who were operated on for posterolateral knee injuries. Three fascial incisions and one lateral midcapsular incision were used to ...
