What’s New in Sports Medicine 2022

Co-author Rachel M. Frank, MD summarizes the 5 most compelling findings from among the studies highlighted in the new What’s New in Sports Medicine” in JBJS. 

Anterior Cruciate Ligament (ACL) Injuries 

– A recent systematic review and meta-analysis evaluated the incidence of radiographic posttraumatic osteoarthritis after transtibial vs. anteromedial femoral tunnel positioning during ACL reconstruction¹. A total of 16 studies with 1,546 patients were included (783 patients who underwent transtibial and 763 who underwent anteromedial ACL reconstruction). Patients were followed for a mean of 10.9 years. Higher overall rates of radiographic posttraumatic osteoarthritis were found for transtibial ACL reconstruction, including when stratified by the duration of follow-up. 

– Another systematic review and meta-analysis compared the outcomes of early operative treatment (≤12 weeks from the time of injury), delayed operative treatment (>12 weeks), and nonoperative treatment of ACL injuries in pediatric and adolescent patients². The analysis included 30 studies with a total of 1,176 patients ≤19 years of age. Overall, the authors recommended ACL reconstruction within 3 months of the initial injury, as this leads to better return-to-sport rates and can play an important role in preserving the joint. 

Anterior Shoulder Instability 

– A randomized controlled trial (RCT) evaluated arthroscopic Bankart repair with and without remplissage for the treatment of anterior shoulder instability with a Hill-Sachs lesion of any size and <15% of anterior glenoid bone loss³. Fifty-four patients were in each group and were followed for 2 years. The patients who underwent Bankart repair with remplissage had significantly lower rates of redislocation and revision procedures. The 2 groups did not differ significantly in terms of patient-reported outcomes, posterior shoulder pain, and the ability to participate in sports at 24 months. 

–A systematic review and meta-analysis evaluated arthroscopic Bankart repair (2,791 patients) vs. the Latarjet procedure (484 patients) in the treatment of recurrent anterior shoulder instability4. Follow-up ranged from 30 days to 10 years. Bankart repair was associated with a higher incidence of recurrence, and when taking into consideration the durations of follow-up, the Latarjet procedure was superior between 6 and 10 years after the initial surgery. Bankart repair was associated with a higher risk of dislocation, particularly between 6 and 10 years. 

Acetabular Labral Tears 

–  A recent RCT compared arthroscopy with physical therapy vs. physical therapy alone in the treatment of symptomatic acetabular labral tears in patients >40 years of age with little to no evidence of femoroacetabular osteoarthritis5. Of the 90 included patients (46 in the arthroscopy group and 44 in the physical therapy group), a total of 81 patients completed 1-year follow-up and were included in the analysis. Of note, 28 of the 44 in the physical therapy group crossed over to arthroscopy, at a mean of 190 days. The intention-to-treat analysis showed significantly higher mean overall scores on the iHOT-33 (International Hip Outcome Tool) and mHHS (modified Harris hip score) in the arthroscopy group. The authors concluded that an age of >40 years should not be considered a contraindication to arthroscopic acetabular labral repair.
