The use of artificial turf in American football continues to grow in popularity, and the effect of these playing surfaces on athletic injuries remains controversial. Knee injuries account for a significant portion of injuries in the National Collegiate Athletic Association (NCAA) football league; however, the effect of artificial surfaces on knee injuries remains ill-defined. ⋯ Artificial turf is an important risk factor for specific knee ligament injuries in NCAA football. Injury rates for PCL tears were significantly increased during competitions played on artificial turf as compared with natural grass. Lower NCAA divisions (II and III) also showed higher rates of ACL injuries during competitions on artificial turf versus natural grass.

It is unclear which patients with recurrent patellar instability require a bony procedure in addition to medial patellofemoral ligament (MPFL) reconstruction. ⋯ At early follow-up of 1 and 2 years, isolated MPFL reconstruction is an effective treatment for patellar instability and provides significant improvements in outcome scores with a low redislocation/instability rate regardless of bony pathologies, including TT-TG distance, Caton-Deschamps index, and trochlear dysplasia. Future data from this cohort will be used to assess long-term outcomes.

The decreased hip range of motion seen in femoroacetabular impingement syndrome (FAIS) may lead to compensatory increased motion at the symphysis pubis (SP) with resultant increased stress on the joint, which can subsequently lead to osteitis pubis. ⋯ A low prevalence (1.8%-2.6%) of SP joint abnormality is seen on imaging in patients with FAIS. These patients may demonstrate significantly inferior clinical outcomes and persistent postoperative pain after FAIS treatment.

The Patient Reported Outcomes Information System (PROMIS) is an efficient metric able to detect changes in global health. ⋯ PROMIS PF and PI can be accurately used to determine improvement or lack thereof with clinically important changes after knee arthroscopy.

Recent evidence has demonstrated a high rate of return to running after hip arthroscopy for femoroacetabular impingement at short-term follow-up. The midterm outcomes and rates of continued running of these patients are unknown. ⋯ Hip arthroscopy for all levels of runners is associated with a significant increase in PROs and a low risk of complications. The rate of return to running is moderately high after hip arthroscopy at midterm follow-up. Hip arthroscopy may be considered for runners presenting with symptoms of femoroacetabular impingement that fail nonoperative treatments. Patients should be educated on the rate of return to running over time and the risks of continued running after hip arthroscopy.
