The incidence of anterior cruciate ligament injury in youth and male soccer athletes: an evaluation of 17,108 players over two consecutive seasons with an age-based sub-analysis
ConclusionA total of 336 ACL injuries were identified in 17,108 youth soccer players from 63 professional clubs with an overall incidence of 2% over 2 seasons of competition. ACL injury rate ranged from 0.3% to 3.8% and was higher in the older and more competitive club divisions.Level of evidenceIV. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

A practical guide to the development and deployment of deep learning models for the orthopedic surgeon: part II
AbstractDeep learning has the potential to be one of the most transformative technologies to impact orthopedic surgery. Substantial innovation in this area has occurred over the past 5  years, but clinically meaningful advancements remain limited by a disconnect between clinical and technical experts. That is, it is likely that few orthopedic surgeons possess both the clinical knowledge necessary to identify orthopedic problems, and the technical knowledge needed to implement dee p learning-based solutions. To maximize the utilization of rapidly advancing technologies derived from deep learning models, orthopedic surgeons...

Fulfilment of patients ’ mandatory expectations are crucial for satisfaction: a study amongst 352 patients after total knee arthroplasty (TKA)
ConclusionPatients ’ expectations of TKA outcomes were high with equal emphasis on knee-related and general health-related aspects. Their fulfilment was positively associated with satisfaction. Surgeons should ask patients about mandatory expectations for successful TKA and counsel them about the likelihood of their fulfilment to avoid unrealistic expectations.Level of evidenceII.

Less than 1% risk of donor-site quadriceps tendon rupture post-ACL reconstruction with quadriceps tendon autograft: a systematic review
ConclusionsQT ACL-R resembles other graft types in its rates and types of postoperative complications. In this exploratory systematic review, no complications of QT ACL-R were found to be disproportionately represented in the literature. This graft type should remain an option with comparable complication rates to other graft choices.Level of evidenceLevel IV.RegistrationThis study was preregistered under PROSPERO with preregistration code CRD42022302078.

Surgeon ’s experience, sports participation and a concomitant MCL injury increase the use of patellar and quadriceps tendon grafts in primary ACL reconstruction: a nationwide registry study of 39,964 surgeries
ConclusionAn HT autograft was used in the vast majority of cases, but PT/QT autografts were used more frequently by experienced surgeons. Prior research has demonstrated significant differences in autograft characteristics. For this reason, patients might benefit if surgery is performed by more experienced surgeons.Level of evidenceLevel III. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

General, spinal or regional anaesthesia does not affect strength performance 6 months after ACL reconstruction
ConclusionsThe findings of this study support the interpretation that the type of anaesthesia has no significant effect on the ability to recover thigh muscle strength 6  months after isolated hamstring ACL reconstruction. With regard to the recovery of athletic performance and return-to-sports testing criteria, there is no reason to avoid regional anaesthesia.Level of evidenceIII.

Arthroscopic centralization reduces extrusion of the medial meniscus with posterior root defect in the ACL reconstructed knee
ConclusionsIn ACL reconstruction, cases involving irreparable medial meniscal posterior root tears, applying arthroscopic centralization for avoiding the meniscal extrusion should be considered. Clinically, in ACL reconstruction cases with irreparable medial meniscal posterior root tears, applying arthroscopic meniscal centralization for avoiding the meniscal extrusion should be considered. Meniscal centralization decreases the extrusion of the MM and offers improvements in knee laxity. (Source: Knee Surgery, Sports Traumatology, Arthroscopy)

No difference in clinical outcome after rotator cuff repair performed within or later than 3  months after trauma: a retrospective cohort study
ConclusionIn this retrospective cohort study, no differences in clinical outcome were found when RC repair was performed between 3  weeks and 3 months or later than 3 months after injury in patients describing their onset of symptoms as traumatic.Level of evidenceIII.

Effect of mediolateral gap difference on postoperative outcomes in navigation-assisted total knee arthroplasty using an ultracongruent insert and the medial stabilising technique
ConclusionThe clinical, functional, and radiographic outcomes, including joint line distance, were comparable between the tight medial and balanced group after mechanical alignment-targeted UC TKA with MST.Level of evidenceLevel III, retrospective comparative study.

Persistent knee extension deficits are common after anterior cruciate ligament reconstruction: a systematic review and meta-analysis of randomised controlled trials
ConclusionsThis review examined the definitions for the measurement and interpretation of postoperative knee extension and established the trajectory of knee extension deficit after ACL injury and reconstruction. While factors associated with loss of extension were identified, the exact trajectory of knee extension deficits was difficult to infer due to discrepancies in measurement techniques and patient variation. On average, 1 in 3 patients may present with loss of extension of at least 3 degrees at 12-month follow-up, decreasing to 1 in 4 at 2  years. These results may be used by clinicians as an upper threshold for ac...
