PURPOSE: The purpose of this study was to investigate how different techniques of single-bundle anterior cruciate ligament (ACL) reconstruction affect subjective knee function via the Knee injury and Osteoarthritis Outcome Score (KOOS) evaluation 2 years after surgery. It was hypothesized that the surgical techniques of single-bundle ACL reconstruction would result in equivalent results with respect to subjective knee function 2 years after surgery. METHODS: This cohort study was based on data from the Swedish National Knee Ligament Register during the 10-year period of 1 January 2005 through 31 December 2014...

The knee is one of the most commonly injured joints in the body. A thorough history and physical examination of the knee facilitates accurate diagnosis of ligament injury. Several examination techniques for the knee ligaments that were developed before advanced imaging remain as accurate or more accurate than these newer imaging modalities. Proper use of these examination techniques requires an understanding of the anatomy and pathophysiology of knee ligament injuries. Advanced imaging can be used to augment a history and examination when necessary, but should not replace a thorough history and physical examination...

Preoperative prediction of hamstring tendon lengths and graft diameter for anterior cruciate ligament (ACL) reconstruction enables better preoperative planning. Presently, no study exists for Indian population where both derivation and verification of a mathematical equation for accurate prediction of hamstring graft dimensions have been done. This study was conducted in two phases: First phase ( derivation cohort): devoted to the study of correlation of length of hamstring tendons and graft diameter with various anthropometric measurements in 123 patients undergoing ACL reconstruction...

BACKGROUND: Hypoplasia or congenital absence of the anterior cruciate ligament (ACL) is a rare disorder occurring in ∼1 in every 6000 births. Although some patients with hypoplasia or agenesis of the ACL may not complain of instability, others desire to participate in more demanding activities that require the stability of a competent ACL. There are limited reports of surgical treatment of this patient population. The purpose of this study was to report ACL reconstruction in a case series of patients with symptomatic congenital ACL deficiency...

Xenograft tendons have been used in few human studies, with variable results. With the advent of novel tissue processing techniques, which may mitigate against an immune-mediated rejection response without adversely affecting mechanical properties, there may now be a clinical role for xenograft tendons, particularly in knee ligament reconstruction. We hypothesize that 'BioCleanse®' processed bovine extensor digitorum medialis (EDM) tendons exhibit favorable time-zero pre-implantation biomechanical characteristics when compared to both unprocessed bovine EDM tendons and BioCleanse® processed human cadaveric allograft tibialis anterior tendons...

Successful posterior cruciate ligament (PCL) reconstruction surgery results from identification and treatment of associated pathology such as posterolateral instability, posteromedial instability, and lower extremity malalignment. The use of strong graft material, properly placed tunnels to as closely as possible approximate the PCL insertion sites, and minimization of graft bending also enhance the probability of PCL reconstruction success. In addition, mechanical graft tensioning, primary and back-up PCL graft fixation, and the appropriate postoperative rehabilitation program are also necessary ingredients for PCL reconstruction success...

BACKGROUND/AIM: Participation in Australian football (AF) has traditionally been male dominated and current understanding of injury and priorities for prevention are based solely on reports of injuries in male players. There is evidence in other sports that indicates that injury types differ between males and females. With increasing participation in AF by females, it is important to consider their specific injury and prevention needs. This study aimed to provide a first injury profile from existing sources for female AF...

Suspensory femoral fixation of anterior cruciate ligament (ACL) grafts with fixed loop button and variable loop button devices has gained popularity for ACL reconstruction. This study examined these 2 methods of fixation to determine their effect on graft laxity and patient-reported outcome scores. A database search was performed to identify patients who had undergone ACL reconstruction with either a fixed loop or a variable loop button technique performed by the primary surgeon. Lysholm, Tegner, and 12-Item Short Form Health Survey scores were obtained, and KT-1000 knee ligament arthrometer (MEDmetric, San Diego, California) mechanical knee testing was performed...
