“…Prior work has shown that increased posterior–inferior directed slope of the tibial plateau is associated with increased risk of suffering an ACL and ACL graft injury, and the increased lateral compartment posterior–inferior directed slopes found in the current study (3.6° for the ACL‐LM group and 1.6 for the ACL group) further exacerbates the chance of a second injury to the ACL graft . In addition, there is evidence that geometry of the articular cartilage and tibial plateau subchondral bone are associated with worsening cartilage degenerative changes in the lateral tibial plateau .…”

“…posterior-inferior directed slopes found in the current study (3.6°for the ACL-LM group and 1.6 for the ACL group) further exacerbates the chance of a second injury to the ACL graft. [24][25][26] In addition, there is evidence that geometry of the articular cartilage and tibial plateau subchondral bone are associated with worsening cartilage degenerative changes in the lateral tibial plateau. 27 Considered in combination, these findings introduce the hypothesis that once ACL injury has occurred, the same geometric characteristics associated with increased risk of suffering the index injury-increased posterior-inferior directed slope of the articular surfaces of the tibia 10,[17][18][19] -are also associated with increased risk of developing PTOA.…”

Combined injury to the anterior cruciate ligament (ACL) and meniscus is associated with earlier onset and increased rates of post‐traumatic osteoarthritis compared with isolated ACL injury. However, little is known about the initial changes in joint structure associated with these different types of trauma. We hypothesized that trauma to the ACL and lateral meniscus has an immediate effect on morphometry of the articular cartilage and meniscus about the entire tibial plateau that is more pronounced than an ACL tear without meniscus injury. Subjects underwent magnetic resonance imaging scanning soon after injury and prior to surgery. Those that suffered injury to the ACL and lateral meniscus underwent changes in the lateral compartment (increases in the posterior–inferior directed slopes of the articular cartilage surface, and the wedge angle of the posterior horn of the meniscus) and medial compartment (the cartilage‐to‐bone height decreased in the region located under the posterior horn of the meniscus, and the thickness of cartilage increased and decreased in the mid and posterior regions of the plateau, respectively). Subjects that suffered an isolated ACL tear did not undergo the same magnitude of change to these articular structures. A majority of the changes in morphometry occurred in the lateral compartment of the knee; however, change in the medial compartment of the knee with a normal appearing meniscus also occurred. Statement of clinical significance: Knee injuries that involve combined trauma to the ACL and meniscus directly affect both compartments of the knee, even if the meniscus and articular cartilage appears normal upon arthroscopic examination. © 2019 Orthopaedic Research Society.

“…The included articles had the following designs: five retrospective cohort studies [5,8,[20][21][22], six prospective cohort studies [2,[23][24][25][26][27], four case series studies [28,-31], five controlled laboratory studies [32-36], three retrospective case control studies [13,15,37], and two prospective case control studies [16,38]. The risk factors catalogued in these studies are grouped into factors the patient can alter against factors the patient has no control over (Table 2).…”

“…While prevention of primary ACL injury has been heavily studied, it is of interest to study the factors associated with recurrent and subsequent contralateral ACL reconstructions. A review of the literature reveals numerous reports of associated modifiable and nonmodifiable factors [2][3][5][6][7][8][12][13][14][15][16][17][18][19]], but no comprehensive evaluation. Awareness of modifiable and non-modifiable factors allows for intervention to decrease rates of recurring ACL rupture.…”

Background: Numerous studies have reported factors associated with recurrent or subsequent contralateral anterior cruciate ligament disruption, but a comprehensive review of the literature has not been performed. Purpose: This study attempts to systematically review the literature and provide an overview of the currently reported risk factors for recurrent and subsequent contralateral ACL reconstructions in order to allow for more efficient identification and intervention of high-risk patients. Study Design: Systematic Review. Methods: The Pubmed and Embase databases were searched using a combination of keywords such as "ACL reconstruction" and "bilateral or recurrent" and "risk factors" and medical subject headings. All studies were screened by two independent reviewers, and articles that met inclusion criteria (non-contact ACL injury, study analyzed risk factors for contralateral ACL injury or graft rupture) were downloaded and read. Results: The initial search yielded 129 articles, of which 36 met inclusion criteria. After duplicates Kakalecik et al.; JAMMR, 29(6): 1-12, 2019; Article no.JAMMR.47906 2 were removed, 23 articles remained. The reference lists of included articles were cross-referenced, and an additional 2 articles were included. Conclusion: Graft harvest site, allograft usage, return to sport, younger age, a positive family history, increased posterior tibial slope, and the number of previous ACL reconstructions are wellreported risk factors for second ACL injury. Recent studies suggest a patients who have negative psychological states in the perioperative periods have worse long-term functional outcomes. Review Article

ACL injuries place the knee at risk for post-traumatic osteoarthritis (PTOA) despite surgical anterior cruciate ligament (ACL) reconstruction. One parameter thought to affect PTOA risk is the initial graft tension. This randomized controlled trial (RCT) was designed to compare outcomes between two graft tensioning protocols that bracket the range commonly used. At 7 years postsurgery, we determined that most outcomes between the two tension groups were not significantly different, that they were inferior to an uninjured matched control group, and that PTOA was progressing in both groups relative to controls. The trial database was also leveraged to gain insight into mechanisms of PTOA following ACL injury. We determined that the inflammatory response at the time of injury undermines one of the joint's lubricating mechanisms.We learned that patients continue to protect their surgical knee 5 years postinjury compared to controls during a jump-pivot activity. We also established that presurgical knee function and mental health were correlated with symptomatic PTOA at 7 years, that there were specific anatomical factors associated with poor outcomes, and that there were no changes in outcomes due to tunnel widening in patients receiving hamstring tendon autografts. We also validated a magnetic resonance imaging technique to noninvasively assess graft strength. In conclusion, the RCT determined that initial graft tensioning does not have a major influence on 7-year outcomes. Therefore, surgeons can reconstruct the ACL using a graft tensioning protocol that is within the window of the two graft tensioning techniques evaluated in this RCT.
