Youth flag football participation has rapidly grown and is a potentially safer alternative to tackle football. However, limited research has quantitatively assessed youth flag football head impact biomechanics. ⋯ Head IRs and magnitudes varied across seasons, thus highlighting multiple season and cohort data are valuable when providing estimates. Head IRs were relatively low across seasons, while linear and rotational acceleration magnitudes were relatively high.

It is unclear whether leukocyte-poor (LP) or leukocyte-rich (LR) varieties of platelet-rich plasma (PRP) as an adjuvant to arthroscopic rotator cuff repair (ARCR) result in improved tendon healing rates. ⋯ The current study demonstrates that LP-PRP reduces the rate of retear and/or incomplete tendon healing after ARCR and improves patient-reported outcomes as compared with a control. However, it is still unclear whether LP-PRP improves the tendon healing rate when compared with LR-PRP.

There is a paucity of midterm outcome data on hip revision arthroscopic surgery. ⋯ Significant improvement in all PROMSs, including the VAS, and high patient satisfaction at minimum 5-year follow-up were reported after revision hip arthroscopy. A high proportion of patients in the revision cohort reached the MCID for the mHHS, HOS-SSS, NAHS, and VAS, with similar rates and magnitudes of improvement relative to the control group. As expected, these data indicate that patients undergoing primary hip arthroscopy have higher PROMSs before and after surgery and lower rates of conversion to arthroplasty.

While platelet-rich plasma (PRP) has been widely studied for musculoskeletal disorders, few studies to date have reported its use for adhesive capsulitis (AC). Fully characterized and standardized allogenic PRP may provide clues to solve the underlying mechanism of PRP with respect to synovial inflammation and thus may clarify its clinical indications. ⋯ Allogenic PRP could be a treatment option for the inflammatory stage of AC.

Increased posterior tibial slope (PTS) has been reported to be associated with irreducible anterior tibial subluxation in extension after anatomic anterior cruciate ligament (ACL) reconstruction (ACLR), which raises concerns about the greater risk of graft roof impingement (GRI) although the tibial tunnel is positioned anatomically. ⋯ Increased PTS (≥12°) was associated with greater risk of GRI after anatomic ACLR. This may provide additional information for counseling patients with greater risk of GRI.
