Historically, poor results of open primary repair of anterior cruciate ligament (ACL) injuries have been reported. In hindsight, however, appropriate patient selection (i.e. proximal tears and good tissue quality) was not performed, because it has recently been recognized that good outcomes of primary ACL repair are possible when selectively performed in patients with proximal tears and good ti...

A 41-year-old female presented with a 3-month history of gradually worsening anterior knee pain, swelling and inability to flex the knee. Magnetic resonance imaging (MRI) revealed a large intra-articular cystic swelling anterior to the anterior cruciate ligament (ACL), extending into the Hoffa's infrapatellar fat pad. Following manipulation under anaesthesia and arthroscopic debridement of the ...

An anterior cruciate ligament (ACL) tear is one of the most common orthopaedic injuries. Optimal results are not always achieved after surgical reconstruction after a surgical technical error, namely, tunnel malposition. Understanding of the anatomy is vital, and several anatomic landmarks can be used to aid in an optimal reconstruction technique. The purpose of this Technical Note is to descri...

Anterior cruciate ligament (ACL) is among the most important ligaments in medial unicompartmental knee replacement (UKR) indication and postoperative survival. There no consensus regarding treatment options of acute ACL rupture after UKR. The debate whether total or reconstruction should be performed if patient has an instability complaint still open. In this case report, we aimed to report sur...

Background: Anatomical single bundle arthroscopic Anterior cruciate ligament (ACL) reconstruction has been the standard treatment for ACL injured patients. It is a minimally invasive procedure that allows the surgeon to understand the internal derangements of the knee joint. ACL is the commonly injured ligament in young adults. The purpose of Arthroscopic ACL reconstruction is to restore the no...

Methods: As the Multicenter ACL (anterior cruciate ligament) Revision Study (MARS) Group, we conducted a multicenter, prospective longitudinal cohort study of patients undergoing revision surgery after anterior cruciate ligament reconstruction. We followed 632 patients who underwent radiographic evaluation of the knee (an anteroposterior weight-bearing radiograph, a posteroanterior weight-beari...

We report a case of an acute pseudogout attack following single-bundle anterior cruciate ligament (ACL) reconstruction in a 35-year-old man. At the initial reconstruction surgery, he was found to have early degenerative changes mainly in the lateral compartment. He presented with acute onset pain and swelling following reconstruction of the ACL. Arthroscopic irrigation was performed and the syn...

A young female athlete suffered from the residual instability of the knee after anterior cruciate ligament (ACL) reconstruction with hamstring autograft. The 3-dimensional (3-D) CT scan showed the "high noon" positioning of the primary femoral bone tunnel. The revision surgery with anatomic double-bundle technique was performed two years after the primary surgery and the femoral tunnels were cr...
