The Presence of a Trochlear Bump and Patella Alta May Predict the Risk of Recurrent Instability After Isolated Medial Patellofemoral Ligament Reconstruction: A Systematic Review and Meta-analysis.

Background: Medial patellofemoral ligament reconstruction (MPFLR) is an excellent surgical option for patients with recurrent patellar instability. This technique has demonstrated significant improvements in patient-reported outcomes, high rates of return to sport, and low rates of failure. However, there is debate regarding the use of isolated MPFLR in the setting of concomitant pathoanatomic features such as patella alta, trochlear dysplasia, or a lateralized tibial tubercle.

Microbial Growth Inhibition Effect, Polyphenolic Profile, and Antioxidative Capacity of Plant Powders in Minced Pork and Beef.

Consumer interest in healthier meat products has grown in recent years. Therefore, the use of plant powders as natural preservatives in the composition of pork and beef products could be an alternative to traditional meat products. This study aimed to assess the effect of different powders, such as blackcurrant, chokeberry, rowan berries, apple, tomato, garlic, and rhubarb, on the microbial growth dynamics in minced pork and beef during refrigerated storage.

When "Immersive" Learning Goes Remote: Interdisciplinary Lessons Learned in a Pandemic.

Background: Due to the COVID-19 pandemic, health professional training programs made substantial changes to shift previously in-person student training opportunities to remote settings.

Objectives: We present lessons learned from changes made to one community-engaged internship program, Bridging the Gaps (BTG)-Pittsburgh, that should prove helpful in future times of crisis.

Methods: BTG-Pittsburgh places inter-disciplinary graduate pairs of students in community-based organizations that serve marginalized populations, to work directly with program participants and develop tangible products aimed to build organizational capacity.

Comparison of Patient-Reported Outcomes for Immediate Unrestricted Weightbearing Versus Restricted Rehabilitation Protocols After Osteochondral Allograft Transplantation to the Distal Femur.

Background: There is no standardized rehabilitation protocol after osteochondral allograft (OCA) transplantation surgery to the distal femur. The spectrum of recommendations includes restrictions to toe-touch weightbearing (TTWB) for 6 weeks and immediate weightbearing as tolerated (WBAT).

Purpose/hypothesis: The purpose of this study was to compare outcomes for immediate unrestricted WBAT to restricted TTWB after OCA transplantation to the distal femur.

Osteochondral Allograft Reaming Significantly Affects Chondrocyte Viability.

Background: Chondrocyte viability is associated with the clinical success of osteochondral allograft (OCA) transplantation.

Purpose: To investigate the effect of distal femoral OCA plug harvest and recipient site preparation on regional cell viability using traditional handheld saline irrigation versus saline submersion.

Study Design: Controlled laboratory study.
