ACL Study Group presents the global trends in ACL reconstruction: biennial survey of the ACL Study Group.

Objectives: The primary objective of this survey was to gauge the current global trends in anterior cruciate ligament reconstruction (ACLR) as reported by the members of the Anterior Cruciate Ligament (ACL) Study Group (SG).

Methods: A survey was created and distributed among the members of the ACL SG consisting of 87 questions and 16 categories related to ACLR, including member demographics, preoperative management, primary ACLR techniques and graft choice, use of concomitant procedures and biological augmentation, postoperative rehabilitation, and more.

Results: The survey was completed by the 140 members of the ACL SG.

ACL Study Group survey reveals the evolution of anterior cruciate ligament reconstruction graft choice over the past three decades.

Purpose: Anterior cruciate ligament reconstruction (ACLR) aims to restore knee function and stability, allowing patients to return to the activities they enjoy and minimize further injury to the meniscus and cartilage and their ultimate progression to osteoarthritis. This study aims to present the evolution of graft choice over the last three decades according to members of the ACL Study Group (SG).

Methods: Prior to the January 2020 ACL SG biannual meeting, a survey was administered consisting of 87 questions and 16 categories, including ACLR graft choice.

Methods: Subjects in this 52-week, phase IIa, multicenter, randomized, double-blind, placebo-controlled, dose-ranging trial received a single 2-ml intraarticular injection of lorecivivint (dose of 0.03 mg, 0.

An analysis of specific lower extremity injury rates on grass and FieldTurf playing surfaces in National Football League Games: 2000-2009 seasons.

Background: Players in the National Football League (NFL) sustain injuries every season as the result of their participation. One factor associated with the rate of injury is the type of playing surface on which the players participate.

Hypothesis: There is no difference in the rate of knee sprains and ankle sprains during NFL games when comparing rates of those injuries during games played on natural grass surfaces with rates of those injuries during games played on the artificial surface FieldTurf.

Potential market for new meniscus repair strategies: evaluation of the MOON cohort.

This study aimed to determine the incidence of meniscal tears and describe the tear morphology and selected treatment in patients undergoing anterior cruciate ligament (ACL) reconstruction. We also will discuss the potential market for future tissue engineering aimed at preserving meniscal function. A multicenter cohort of 1014 patients undergoing ACL reconstruction between January 2002 and December 2003 was evaluated.

Success of meniscal repair at anterior cruciate ligament reconstruction.

Background: Meniscal repair is performed in an attempt to prevent posttraumatic arthritis resulting from meniscal dysfunction after meniscal tears. The socioeconomic implications of premature arthritis are significant in the young patient population. Investigations and techniques focusing on meniscus preservation and healing are now at the forefront of orthopaedic sports medicine.

A systematic review of anterior cruciate ligament reconstruction rehabilitation: part II: open versus closed kinetic chain exercises, neuromuscular electrical stimulation, accelerated rehabilitation, and miscellaneous topics.

Anterior cruciate ligament (ACL) reconstruction is a common surgical knee procedure that requires intensive postoperative rehabilitation by the patient. A variety of randomized controlled trials have investigated aspects of ACL reconstruction rehabilitation. A systematic review of English language level 1 and 2 studies identified 54 appropriate randomized controlled trials of ACL rehabilitation.

A systematic review of anterior cruciate ligament reconstruction rehabilitation: part I: continuous passive motion, early weight bearing, postoperative bracing, and home-based rehabilitation.

Anterior cruciate ligament (ACL) reconstruction is a common surgical knee procedure that requires intensive postoperative rehabilitation by the patient. A variety of randomized controlled trials have investigated aspects of ACL reconstruction rehabilitation. A systematic review of English language level 1 and 2 studies identified 54 appropriate randomized controlled trials of ACL rehabilitation.

Risk of tearing the intact anterior cruciate ligament in the contralateral knee and rupturing the anterior cruciate ligament graft during the first 2 years after anterior cruciate ligament reconstruction: a prospective MOON cohort study.

Background: The risk of tear of the intact anterior cruciate ligament in the contralateral knee after anterior cruciate ligament reconstruction of the opposite knee and the incidence of rupturing the anterior cruciate ligament graft during the first 2 years after surgery have not been extensively studied in a prospective manner. Clinicians have hypothesized that the opposite normal knee is at equal or increased risk compared with the risk of anterior cruciate ligament graft rupture in the operated knee.

Hypothesis: The risk of anterior cruciate ligament graft rupture and contralateral normal knee anterior cruciate ligament rupture at 2-year follow-up is equal.

Pronation-external rotation ankle fractures in 3 professional football players.

We found no reports of ankle fracture management in professional football players in the orthopedic literature. In this small series of ankle fractures in professional football players, all 3 had the same pronation-external rotation injury pattern. Given the high demands placed on the ankle by these professional athletes, we chose to use a 4.

Return to play issues in upper extremity injuries.

Objective: The purpose of this paper is to outline general treatment and return to play (RTP) strategies as they pertain to athletes with various upper extremity injuries. It is not intended to be a comprehensive review of these injuries.

Data Sources/synthesis: A review of the literature plus expert opinion served as the basis for recommendations made regarding management strategies for returning the athlete to play after upper extremity injury.

A biomechanical comparison of posterior cruciate ligament reconstructions using single- and double-bundle tibial inlay techniques.

Background: The efficacy of using a double-bundle versus single-bundle graft for posterior cruciate ligament reconstruction has not been demonstrated.

Hypothesis: A double-bundle graft restores knee kinematics better than a single-bundle graft does in tibial inlay PCL reconstructions.

Study Design: Controlled laboratory study.

Evaluation and treatment of posterior cruciate ligament injuries: revisited.

Current knowledge and treatment of posterior cruciate ligament injuries continue to lag behind that of anterior cruciate ligament injuries. This is the result of the relative infrequency of posterior cruciate ligament injuries and the lack of consensus with respect to its natural history, surgical indications, technique, and postoperative rehabilitation. Recent anatomical and biomechanical studies have improved our understanding of the posterior cruciate ligament in an attempt to reproduce its anatomy and function during reconstruction.

Plantar ganglion cyst associated with stress fracture of the third metatarsal.

Ganglion cysts of the foot and ankle occur relatively infrequently. Metatarsal stress fractures occur in a variety of athletes who subject their lower extremities to repetitive loading. In this article, we report the case of a professional football player with a plantar forefoot ganglion cyst associated with a stress fracture of the third metatarsal.

Jumping versus nonjumping anterior cruciate ligament injuries: a comparison of pathology.

Objective: To compare pathology in knees with an anterior cruciate ligament (ACL) injury as a result of a jumping mechanism with knees injured from a nonjumping mechanism.

Design: This was a prospective study of 263 consecutive patients with a complete ACL tear and no subsequent giving way episodes nor reinjuries prior to undergoing an ACL reconstruction. The patients were placed into one of two groups: those with knees injured as a result of a jumping injury, and those with knees injured as a result of a nonjumping injury.

Non-linear fitting of mechanical data for efficacy determination of single versus double bundle Achilles tendon grafts for PCL reconstructions.

The Posterior Cruciate Ligament (PCL) consists of two primary bundles and is the primary restraint to posterior tibial translation. The emergence of the Posterior Tibial Inlay Technique (PTIT) has demonstrated a mechanical advantage over the commonly used Tibial Tunnel Method (TTM). This study was designed to investigate the effects on knee mechanics from both a Single-bundle (SB) and Double-bundle (DB) Achilles tendon PCL reconstruction using a PTIT.
