AI Article Synopsis
- There is evidence suggesting that genetics play a role in tendon and ligament injuries, particularly in elite rugby athletes.
- A study compared 663 elite male rugby players to 909 non-athletes, examining 13 specific gene variants associated with injury risk.
- Findings indicate certain genetic variants (like rs8090 and rs1800255) are more common in elite rugby players, suggesting they may have a genetic advantage that helps protect them from injuries, potentially aiding in their elite performance.
Article Abstract
There is growing evidence of genetic contributions to tendon and ligament pathologies. Given the high incidence and severity of tendon and ligament injuries in elite rugby, we studied whether 13 gene polymorphisms previously associated with tendon/ligament injury were associated with elite athlete status. Participants from the RugbyGene project were 663 elite Caucasian male rugby athletes (RA) (mean (standard deviation) height 1.85 (0.07) m, mass 101 (12) kg, age 29 (7) yr), including 558 rugby union athletes (RU) and 105 rugby league athletes. Non-athletes (NA) were 909 Caucasian men and women (56% female; height 1.70 (0.10) m, mass 72 (13) kg, age 41 (23) yr). Genotypes were determined using TaqMan probes and groups compared using Χ and odds ratio (OR). rs8090 AA genotype was more frequent in RA (27%) than NA (23%; = 0.006). rs1800255 A allele was more frequent in RA (26%) than NA (23%) due to a greater frequency of GA genotype (39% vs 33%). For rs4919510, RA had 1.7 times the odds of carrying the CC genotype compared to NA. rs591058 TT genotype was less common in RA (25.1%) than NA (31.2%; < 0.04). For rs4660148, RA had 1.6 times the odds of carrying the TT genotype compared to NA. It appears that elite rugby athletes have an inherited advantage that contributes to their elite status, possibly via resistance to soft tissue injury. These data may, in future, assist personalised management of injury risk amongst athletes. The elite rugby athletes we studied had differing genetic characteristics to non-athletes regarding genetic variants previously associated with soft-tissue injury risk. rs8090, rs1800255, rs4919510, rs591058 and rs4660148 were all associated with elite status in rugby.We propose that elite rugby athletes might possess an inherited resistance to soft tissue injury, which has enabled them to achieve elite status despite exposure to the high-risk environment of elite rugby.

Osteoarthritis (OA) is heterogeneous and involves structural changes in the whole joint, such as cartilage, meniscus/labrum, ligaments, and tendons, mainly with short T2 relaxation times. Detecting OA before the onset of irreversible changes is crucial for early proactive management and limit growing disease burden. The more recent advanced quantitative imaging techniques and deep learning (DL) algorithms in musculoskeletal imaging have shown great potential for visualizing "pre-OA.

Background: The aim of this study was to predict intraoperative graft diameter with our new method by evaluating the cross-sectional areas (CSAs) of the hamstrings in axial sections of MRI.
Methods: This study included 78 patients who underwent single-bundle ACLR between 2022 and 2023. MRIs of the patients were evaulated preoperatively and four CSAs of the hamstring tendons were measured in two different regions by two participants.

Anterior Cruciate Ligament Revision Using Bone-Patellar Tendon-Bone Autograft and Lateral Extra-articular Tenodesis.

Revision of anterior cruciate ligament reconstruction presents various challenges not encountered in the primary settings, including malpositioned tunnels, tunnel widening, and the lack of consensus on the ideal graft to be used. This Technical Note describes a one-stage anterior cruciate ligament reconstruction revision using a bone-patellar tendon-bone autograft combined with lateral extra-articular tenodesis. This technique represents the ideal approach to tackle complex revision cases primarily characterized by tibial and femoral tunnel osteolysis and rotational knee instability.

The medial patellofemoral complex provides the primary static restraint to lateral patellar translation and is composed of the medial patellofemoral ligament and medial quadriceps tendon femoral ligament. Multiple techniques including medial patellofemoral ligament and/or medial quadriceps tendon femoral ligament reconstruction have demonstrated good results; however, modification of the femoral fixation technique is required for skeletally immature patients or revision cases in which anatomic bony fixation on the femur is not possible. This technique describes an all-soft-tissue procedure for single-bundle medial patellofemoral complex reconstruction in which the graft is fixed on the adductor tendon while using the medial collateral ligament as a distalizing pulley, for anatomic and isometric recreation of the native ligament.
