BACKGROUND Transtibial drilling techniques are widely used for arthroscopic reconstruction of the anterior cruciate ligament, most likely because they simplify femoral tunnel placement and reduce surgical time. Recently, however, there has been concern that this technique results in nonanatomically positioned bone tunnels, which may cause abnormal knee function. The purpose of this study was to...

Recently, medial patellofemoral ligament reconstruction has gained popularity as a treatment modality for recurrent patellar instability.2-6 Patients who have failed surgical interventions including lateral release, medial patellofemoral ligament reefing, and distal realignment may be good candidates for medial patellofemoral ligament reconstruction. The anatomy and biomechanics of the medial p...

Lateral ankle instability may be associated with intra-articular ankle pathology and peroneal tendon pathology. This study was conducted to determine the relative incidence of associated pathology identified during lateral ligament repair. This information was analysed to determine if a standard surgical protocol of arthroscopic ankle assessment followed by ligament repair through a longitudina...

Arthrosis following rupture of the anterior cruciate ligament has been analysed in two series. The first series was derived from a review of 150 cases of reconstruction of the anterior cruciate ligament with a follow-up of 3 years or more. Arthrosis was seen to have developed in 13.3%. The second series was concerned with 64 cases of unilateral arthrosis treated by upper tibial valgus osteotomy...

background: daily increased rate of anterior cruciate ligament (acl) injuries in athletes calls for more investigation in these patients to differentiate copers from noncoper acl-deficient (acld) knees as soon as possible. objectives: the current study aims to introduce a new electromyographic protocol, named voluntary response index (vri), that might help to categorize and differentiate patien...

abstract background and aim: lack of balance in pattern and activity of quadriceps and hamstring muscles increases the risk of anterior cruciate ligament injury (acl). the purpose of the present study was to investigate the changes in pattern and activity of vastus medialis and semitendinosusmuscles in landing from different heights and to understand if these changes will increase the risk of a...

In a simplified way, one can divide the subtalar joint into two parts, an anterior and a posterior part. Anteriorly, the talar head is located on the anterior and middle facets of the calcaneus, forming the acetabulum pedis with the posterior surface of the navicular bone.1 However, it is important to mention that the talar head is not only supported by the articulating surfaces of the calcaneu...

PURPOSE To examine the anatomy of the lateral ankle after arthroscopic repair of the lateral ligament complex (anterior talofibular ligament [ATFL] and calcaneofibular ligament [CFL]) with regard to structures at risk. METHODS Ten lower extremity cadaveric specimens were obtained and were screened for gross anatomic defects and pre-existing ankle laxity. The ATFL and CFL were sectioned from t...
