CASE: Numerous outcome studies regarding anterior cruciate ligament (ACL) reconstruction demonstrate the ability of athletes to return to a high level of play. However, to our knowledge, there is limited literature regarding return to play following injury to both the ACL and the fibular collateral ligament (FCL). We describe the case of a National Basketball Association (NBA) player who sustained a combined ACL and FCL knee injury and subsequently underwent surgical reconstruction of both affected ligaments...

PURPOSE: The purpose of this study was to evaluate the differences in intra-articular pathology, demographic characteristics, and radiographic characteristics of the knee associated with primary anterior cruciate ligament reconstruction (ACLR) versus revision ACLR at the time of initial presentation with either a native anterior cruciate ligament tear or an anterior cruciate ligament graft tear. Secondarily, we aimed to investigate risk factors for concomitant medial and lateral meniscal tears and cartilage injuries at the time of ACLR...

BACKGROUND: Limited information in basic science and clinical trials exists to determine if ligament healing may be accelerated with the use of biological adjuvants, such as platelet-rich plasma (PRP). However, there has been widespread acceptance of PRP for use in clinical practice, despite an inadequate understanding of its biological mechanism of action. PURPOSE: To determine whether a single dose of PRP could accelerate ligament healing and correspondingly improve histological characteristics and biomechanical properties when injected immediately postoperatively into the injured medial collateral ligament (MCL) of New Zealand White rabbits...

REVIEW

With the recent "description" of the anterolateral ligament (ALL) of the knee, its role in controlling rotational stability has reemerged. An improved understanding of the anatomy of the anterolateral complex of the knee has led to an expansion of the literature on the biomechanics of many structures, including the contribution of the iliotibial band and its deep (Kaplan) fibers, the capsulo-osseous layer, the ALL, and the lateral meniscal posterior root to knee stability. This article describes the primary and secondary roles of key anatomic structures at the anterolateral aspect of the knee...

The olive (Olea europaea L.) is a typical important perennial crop species for which the genetic determination and even functionality of self-incompatibility (SI) are still largely unresolved. It is still not known whether SI is under gametophytic or sporophytic genetic control, yet fruit production in orchards depends critically on successful ovule fertilization. We studied the genetic determination of SI in olive in light of recent discoveries in other genera of the Oleaceae family. Using intra- and interspecific stigma tests on 89 genotypes representative of species-wide olive diversity and the compatibility/incompatibility reactions of progeny plants from controlled crosses, we confirmed that O...

Bervillé et al. express concern about the existence of the diallelic self-incompatibility (DSI) system in Olea europaea, mainly because our model does not account for results from previous studies from their group that claimed to have documented asymmetry of the incompatibility response in reciprocal crosses. In this answer to their comment, we present original results based on reciprocal stigma tests that contradict conclusions from these studies. We show that, in our hands, not a single case of asymmetry was confirmed, endorsing that symmetry of incompatibility reactions seems to be the rule in Olive...

The new self-incompatibility system (SI) was presented by Saumitou-Laprade, Vernet, Vekemans et al. (2017). Evolutionary Applications based on 89 crosses between varieties in the olive tree. Four main points are not clear. We are examining here as follows: (i) the assertion that the self-incompatibility system is sporophytic was not sustained by pollen germination data; (ii) surprisingly, the new model does not explain that about one-third of pairwise combinations of olive varieties leads to asymmetric fruit setting; (iii) DNA preparation from one seed may contain two embryos, and thus, embryos should be separated before seed extraction; (iv) although effective self-fertility in olive varieties was reported by many studies, the DSI model fails to explain self-fertility in some olive varieties...

BACKGROUND: Until recently, anterior cruciate ligament (ACL) tears in older patients were treated conservatively; however, these patients often experienced significant pain and instability. PURPOSE/HYPOTHESIS: The purpose of this study was to compare the patient-reported outcomes, patient satisfaction, and failure rates of primary ACL reconstruction between a younger (age 20-30 years) and older (age 50-75 years) patient cohort. It was hypothesized that patients in the older cohort could achieve comparable clinical outcomes and retear rates following ACL reconstruction with a bone-tendon-bone autograft or allograft compared with the younger patients...

BACKGROUND: Platelet-rich plasma (PRP) is a blood-derived preparation whose use has grown exponentially in orthopaedic practice. However, there remains an unclear understanding of the biological properties and effects of PRP on musculoskeletal healing. Heterogeneous processing methods, unstandardized nomenclature, and ambiguous classifications make comparison among studies challenging. A comprehensive assessment of orthopaedic clinical PRP trials is key to unraveling the biological complexity of PRP, while improving standardized communication...

BACKGROUND: Cartilage lesions are a significant cause of morbidity and impaired knee function; however, cartilage repair procedures have failed to reproduce native cartilage to date. Thus, osteochondral allograft (OCA) transplantation represents a 1-step procedure to repair large chondral defects without the donor site morbidity of osteochondral autograft transplantation. PURPOSE: To perform a systematic review of clinical outcomes and failure rates after OCA transplantation in the knee at a minimum mean 2 years' follow-up...

BACKGROUND: Magnetic resonance imaging (MRI) of the knee is a highly sensitive and specific method for diagnosing acute posterior cruciate ligament (PCL) tears, with a reported accuracy of 96% to 100%. In chronic and revision settings, these injuries may be missed on MRI because of the apparent continuity of nonfunctional PCL fibers. Posterior tibial translation (PTT) of the medial compartment has been identified as a potential secondary finding of PCL tear on routine MRI. Purpose/Hypothesis: The purpose of this study was to evaluate the sensitivity of PTT on MRI associated with PCL injuries and compare it with the sensitivity of a radiologist's MRI interpretation with preoperative posterior knee stress radiographs as the gold standard...
