Margin convergence vs. superior capsular reconstruction for massive irreparable rotator cuff tears: outcomes are equivalent unless there is preoperative pseudoparesis.

Background: Margin convergence (MC) and superior capsular reconstruction (SCR) are common treatment options for irreparable rotator cuff tears in younger patients, although they differ in associated costs and operative times. The purpose of this study was to compare range of motion, patient-reported outcomes (PROs), and reoperation rates following MC and SCR. We hypothesized superior outcomes after SCR relative to MC regarding functional outcomes, subjective measures, and reoperation rates.

The impact of the COVID-19 pandemic on frozen shoulder incidence rates and severity.

Background: Although there is evidence that the COVID-19 pandemic had profound physiological and psychological effects, there is no research aimed at understanding if the pandemic has had an impact on the incidence or severity of frozen shoulder (FS). The aim of this study was to compare the incidence and severity of idiopathic FS before and during the pandemic.

Methods: A retrospective cohort study was performed to establish the incidence of FS during the pandemic, from March 2020 to January 2021 (pandemic study period), compared to the same time period 1 year earlier, before the pandemic (control group).

One-stage revision anterior cruciate ligament reconstruction in cases with excessive tunnel osteolysis. Results of a new technique using impaction bone grafting.

Background: This level IV study describes a new one-stage procedure for revision ACL reconstruction in cases with extreme tunnel widening.

Methods: Eight consecutively treated subjects requiring ACL revision and presenting with excessive tunnel widening (87.5% to 250% tunnel enlargement) were included in this study.
