Case Reports Comparative Study
Concomitant meniscal allograft transplantation and autologous chondrocyte implantation: minimum 2-year follow-up.
Although recent studies have shown intermediate-term success of both meniscal allograft transplantation (MAT) and autologous chondrocyte implantation (ACI) performed separately, there have been no peer-reviewed studies focused prospectively on the combined procedure. By potentially reestablishing a compartment contact area closer to normal, MAT may allow a more optimal environment for ACI by reducing stress (stress =force/unit area). On the other hand, the literature suggests that MAT alone in the presence of extensive chondrosis performs poorly. Restoring the articular cartilage may allow the MAT to perform more similarly to series with nearly normal articular cartilage. ⋯ At a minimum of 2-year follow-up, MAT in combination with ACI demonstrates improvement in both symptoms and knee function. However, the improvements are less than literature-reported outcomes of either procedure performed in isolation.

Comparative Study
Importance of tibial slope for stability of the posterior cruciate ligament deficient knee.
Previous studies have shown that increasing tibial slope can shift the resting position of the tibia anteriorly. As a result, sagittal osteotomies that alter slope have recently been proposed for treatment of posterior cruciate ligament (PCL) injuries. ⋯ These data suggest that increasing tibial slope may be beneficial for patients with PCL-deficient knees.

A type VIII superior labrum anterior posterior lesion represents pathologic posteroinferior extension of a type II superior labrum anterior posterior lesion with injury to the insertion of the posterior band of the inferior glenohumeral ligament. No reports in the literature describe arthroscopic treatment of a type VIII superior labrum anterior posterior lesion and its associated glenohumeral instability. ⋯ Arthroscopic capsulolabral reconstruction is an effective and reliable treatment for glenohumeral instability due to a type VIII superior labrum anterior posterior lesion in the contact, noncontact, and throwing athlete. Successful postoperative return to sport is a reasonable expectation.

Overtensioning of medial patellofemoral ligament reconstructions may lead to adverse surgical outcomes. ⋯ Overtensioning can be avoided by applying low loads to medial patellofemoral ligament reconstructions, which reestablished normal translation and patellofemoral contact pressures.

A high body mass index and previous ankle sprains have been shown to increase the risk of sustaining noncontact inversion ankle sprains in high school football players. ⋯ The increased risk of a noncontact inversion ankle sprain associated with a high body mass index and a previous ankle sprain was eliminated by the balance training intervention.
