Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of OrthoBuzz summaries of these “What’s New” articles. This month, co-author Christopher Y. Kweon, MD selected the 5 most clinically compelling findings from the 40 studies summarized in the April 15, 2020 “What’s New in Sports Medicine.”
ACL Graft Choice
—A randomized controlled trial (RCT) comparing bone-tendon-bone autograft, quadrupled hamstring tendon autograft, and double-bundle hamstring autograft for ACL reconstruction in young adults found the following:
- No between-group differences in patient-reported quality-of-life scores at 5 years
- Significantly higher rates of traumatic graft reinjuries in the hamstring-tendon and double-bundle groups
- Relatively low (37%) return to preinjury level of activity for the entire population, with no significant between-group differences
Meniscal Repairs with Bone Marrow Venting
—A double-blinded RCT1 of patients with complete, unstable, vertical meniscal tears compared isolated meniscal repair to meniscal repair with a bone marrow venting procedure (BMVP). Meniscal healing, as assessed with second-look arthroscopy at a mean of 35 weeks, was 100% in the BMVP group and 76% in the control group (p = 0.0035). Secondary pain and function measures at 32 to 51 months were also better in the BMVP group.
Rotator Cuff Repair Rehab
—A multisite RCT2 among >200 patients who received arthroscopic repair of a full-thickness rotator cuff tear compared standard rehabilitation (patients wore a sling at all times except when performing prescribed exercises) and early mobilization (patients wore a sling only when needed for comfort). Early mobilizers showed significantly better forward flexion and abduction at 6 weeks, but no subjective or objective differences (including retear rate) were found at any other time points.
Remplissage for Anterior Shoulder Instability
—A systematic review3 of studies investigating arthroscopic Bankart repair with and without remplissage found significantly higher instability-recurrence rates with isolated Bankart repair. Overall, the addition of remplissage appears to yield better patient-reported function scores compared with isolated Bankart repair alone.
Syndesmotic Ankle Injuries
—A meta-analysis of 7 RCTs (335 patients)4 comparing dynamic versus static fixation for syndesmotic injuries of the ankle found that the overall risk of complications was significantly lower in the dynamic fixation group. Reoperation rates were similar in the two groups, but implant breakage or loosening was reduced with dynamic fixation devices. Compared with static fixation, the dynamic fixation group also had higher AOFAS scores and lower VAS scores at various time points.
