The aim of this study was to examine the relationship between BstUI restriction fragment length polymorphisms (RFLP) C/T (rs 12722) and DpnII RFLP B1/B2 (rs 13946) COL5A1 polymorphisms and the anterior cruciate ligament (ACL) rupture in competitive team-sport athletes. Sixty-eight team-sport players (n = 36 women and n = 32 men) with non-contact ACL rupture (ACLR) occurred during sport practices (ACLR Group) and 42 healthy players (n = 20 women and n = 22 men) (Control Group) participated in the study. Genomic DNA was extracted from buccal swab with salting out method. All samples were genotyped for the polymorphisms rs12722 and rs13946 by polymerase chain reaction (PCR) and restriction enzymes analysis. No significant difference has been found between ACRL and Control groups in age, height, weight body, mass index, sport practice (hours/week) and gender distribution among the different team sports. Control group had longer sport careers ( < 0.005). The frequency distributions of COL5A1 DpnII nucleotide polymorphisms were in Hardy-Weinberg equilibrium (HWE) in both groups ( of the Hardy-Weinberg (HW) -test > 0.005). Genotype frequencies of COL5A1 BstUI RFLP C/C was lower in the ACLR group compared to the Control group ( of the HW-test = 0.001). Combined CC, B1B1 genotypes showed a protective effect against ACL rupture (OR = 83.3 / 16.7 = 5). The COL5A1 gene may be one of the genetic factors associated with ACLR in team sport.

Exploring Rehabilitation Protocols for Primary Anterior Cruciate Ligament Repair: Insights from a Scoping Review.
Am J Phys Med Rehabil
January 2025
Department of Physical and Rehabilitation Medicine, Hacettepe University Medical School, Ankara, Turkey.
Objectives: The primary repair of the anterior cruciate ligament (ACL) has re-emerged as a treatment for acute ruptures. While numerous studies have investigated rehabilitation after ACL reconstruction, few have focused on primary repair. We aimed to describe the rehabilitation protocols for primary ACL repair, and to identify knowledge gaps and differences between primary ACL repair and reconstruction.

Importance: Patients with arthritis and ruptured cruciate ligaments typically require surgery. Following surgery, it is necessary to improve joint function in early stage.
Objective: This study aimed to investigate the impact of intraoperative intra-articular injection of the ELHLD peptide (L-glutamyl-L-leucyl-L-histidyl-L-leucyl-L-aspartic acid) on postoperative stifle function in patients with medial patella luxation grade 3 and osteoarthritis grade 2 undergoing tibial plateau leveling osteotomy due to anterior cruciate ligament (ACL) rupture.
Background: The co-occurrence of anterior cruciate ligament (ACL) rupture with medial collateral ligament (MCL) rupture is a compound injury that can be associated with meniscal tears.
Purpose: To report the characteristics of meniscal tears in knees with isolated ACL versus combined ACL and MCL injuries, analyzing their frequency, distribution by site, and lesion type.
Study Design: Cross-sectional study; Level of evidence, 3.
Patient-specific cutting guides allow 1° precision in asymmetric anterior closing-wedge osteotomy.

Purpose: Asymmetric anterior closing-wedge high tibial osteotomy (ACWHTO) allows correction of both excessive posterior tibial slope (PTS) and varus deformity. However, the complexity of this surgery requires a high degree of accuracy, which is less likely to be achieved with standard instrumentations. This study aimed to determine the accuracy of 3D patient-specific cutting guides (PSCGs) to provide the accurate planned correction in the frontal and sagittal planes.

- The study examined the epidemiology and risk factors for ACL injuries in handball, hypothesizing that the injury rates are high, akin to other sports like football.
- A total of 84 ACL injuries were reported over six seasons, with a notable 46.3% being re-ruptures; higher injury rates were found in the first division compared to the second division.
- Key risk factors identified include previous knee injuries and increased time spent in matches, indicating a significant concern for professional handball players.
