BACKGROUND Bio-enhanced ACL repair, where the suture repair is supplemented with a biological scaffold, is a promising novel technique to stimulate healing after ACL rupture. However, the histological properties of a successfully healing ACL and how they relate to the mechanical properties have not been fully described. HYPOTHESIS/PURPOSE The purpose of the study was to determine which histol...

BACKGROUND Studies investigating the development of ACL injuries over time in football are scarce and more data on what happens before and after return to play (RTP) are needed. AIM To investigate (1) time trends in ACL injury rates, (2) complication rates before return to match play following ACL reconstruction, and (3) the influence of ACL injury on the subsequent playing career in male pro...

INTRODUCTION Anterior cruciate ligament (ACL) degeneration is observed in most osteoarthritis (OA)-affected knee joints. However, the specific spatial and temporal relations of these changes and their association with extracellular matrix (ECM) degeneration are not well understood. The objective of this study was to characterize the patterns and relations of aging-related and OA-associated chan...

Rupture of the anterior cruciate ligament (ACL) is one of the most frequent forms of knee trauma. The traditional surgical treatment for ACL rupture is single-bundle reconstruction. However, during the past few years there has been a shift in interest toward double-bundle reconstruction to closely restore the native ACL anatomy. This paper evaluates the basis for double-bundle ACL reconstructio...

BACKGROUND About 12% of patients who have undergone primary anterior cruciate ligament (ACL) reconstruction sustain a contralateral ACL injury within 5 years. PURPOSE To investigate patient-reported knee function, quality of life, and activity level in patients with bilateral ACL injuries. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A search of hospital records identified 147...

BACKGROUND There is a high incidence of anterior cruciate ligament (ACL) injuries among National Football League (NFL) athletes; however, the incidence of reinjury in this population is unknown. PURPOSE This retrospective epidemiological study analyzed all publicly disclosed ACL tears occurring in NFL players between 2010 and 2013 to characterize injury trends and determine the incidence of r...

INTRODUCTION Many case reports have documented the successful use of titanium miniscrews for orthodontic anchorage. However, the literature lacks a well-controlled study examining the effect of miniscrew diameter on anchorage force resistance. The purpose of this in-vitro study was to compare the force resistance of larger-diameter monocortical miniscrews to smaller-diameter monocortical minisc...

The geometric optimization of orthopedic screws can considerably increase their orthopedic efficiency. Due to the high geometric parameters of orthopedic screws, a finite element simulation is an effective tool for analyzing and forecasting the effect of the parameters on the load-bearing capacity of different types of screws and bones. Thus, in the present study, the tensile strength of a typi...

Study Design Mechanical study. Purpose To compare the pullout strength of different screw designs and augmentation techniques in an osteoporotic bone model. Overview of Literature Adequate bone screw pullout strength is a common problem among osteoporotic patients. Various screw designs and augmentation techniques have been developed to improve the biomechanical characteristics of the bone-...

Cidera anterior cruciate ligament (ACL) merupakan rusaknya pada yang jaringan menghubungkan tulang femur dan tibia. ACL sering terjadi saat berolahraga atau bahkan melakukan kegiatan sehari-hari. Penelitian ini menggunakan pendekatan studi kasus untuk mengetahui efektifitas penatalaksanaan fisioterapi ACL. Problematika pasien yaitu mengalami nyeri gerak tekan, keterbatasan Range of motion (ROM)...
