The central immunological disturbance in systemic lupus erythematosus (SLE) is autoantibody production. Some of these antibodies affecting components of the cell nucleus are the major characteristics of SLE. The present study was aimed to assess importance of anticardiolipin (ACL) antibody and its association with clinical state in SLE patients. A cross sectional study was performed on 100 pati...

methods we handed out questionnaires to 80 female soccer players with a history of acl injury (90 acl injuries). the players were asked about the injury characteristics, injury circumstance, maneuver being performed when the injury occurred, and playing type associated with the injury. the players responded to the questionnaire under the guidance of the medical staff of each team. results the 8...

BACKGROUND Skiing and snowboarding have become increasingly popular since the inception of the winter X-Games in 1997. PURPOSE To determine (1) rate of return to sport (RTS) to the winter X-Games following anterior cruciate ligament (ACL) reconstruction and (2) performance upon RTS following ACL reconstruction. HYPOTHESES There is a high rate of RTS to the winter X-Games in subjects undergo...

A 24 year old otherwise healthy male was presented with a chief complaint of giving way in the left knee. MRI reportedcomplete anterior cruciate ligament (ACL) tearing. Arthroscopy showed ACL agenesis, ring-shaped lateral meniscus,and an anomalous thick band extending from the anterior horn of the lateral meniscus to the intercondylar notch of thelateral femoral condyle, which...

Is there a correlation between increased posterior-inferior tibial slope angle and noncontact anterior cruciate ligament (ACL) injury? Does increasing the posterior-inferior tibial slope angle increase the risk of bilateral ACL injury? A computerized relational database (Access 2007; Microsoft Inc, Redmond, Washington) was used to conduct a retrospective review of patients undergoing bilateral ...

BACKGROUND Many patients who undergo anterior cruciate ligament (ACL) reconstructive surgery develop post-traumatic osteoarthritis (PTOA). ACL reconstructive surgery may not fully restore pre-injury joint biomechanics, thereby resulting in further joint damage and contributing to the development of PTOA. In an ovine model of idealized ACL reconstruction (ACL-R), it has been shown that signs of ...

The anterior cruciate ligament (ACL) is one of the most frequently injured structures during high-impact sporting activities. Gene expression analysis may be a useful tool for understanding ACL tears and healing failure. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) has emerged as an effective method for such studies. However, this technique requires the use of suitable...

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...
