In a retrospective case-cohort analysis of 364 shoulders that had primary repair of recurrent anterior instability, Zimmermann et al. conclude in the December 7, 2016 issue of JBJS that arthroscopic Bankart repairs were inferior to the open Latarjet procedure, at a mean follow-up of 10 years.
Specific 10-year outcome comparisons included:
- Redislocations in 13% of the Bankart shoulders vs 1% of the Latarjet shoulders
- Apprehension (fear of the shoulder dislocating with the arm in abduction and external rotation) in 29% of the Bankart patients vs 9% of the Latarjet patients
- Cumulative revision rate for recurrent instability of 21% in the Bankart group vs 1% in the Latarjet group
- Not-satisfied rating from 13.2% of patients in the Bankart group vs 3.2% in the Latarjet group
Overall, there were few early and almost no late failures after the Latarjet procedure, while the arthroscopic Bankart repair was associated with an increasing failure rate over time. The authors say that this study’s longer-term analysis confirms “the contention that arthroscopic Bankart reconstructions fail progressively” and supports “the observation that restoration of stability with the Latarjet procedure is stable over time.”
Every month, JBJS publishes a Specialty Update—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 all OrthoBuzz Specialty Update summaries.
This month, Nitin Jain, MD, MSPH, a co-author of the November 16, 2016 Specialty Update on Orthopaedic Rehabilitation, selected the five most clinically compelling findings from among the more than 40 studies summarized in the Specialty Update.
–A prospective cohort study1 evaluating the benefit of early imaging (within 6 weeks of index visit) for patients ≥65 years old with new-onset back pain found that those with early imaging had significantly higher resource utilization and expenditures compared with matched controls who did not undergo early imaging. One year after the index visit, authors found no significant between-group differences in patient-reported pain or disability. They concluded that “early imaging should not be performed routinely for older adults with acute back pain.”
–A randomized clinical trial2 comparing 10 days of NSAID monotherapy with 10 days of NSAIDs + muscle relaxants or opioids for acute nonradicular low back pain found no significant differences across the groups for pain, functional impairment, or use of health care resources. The authors said these findings suggest that combination therapy is not better than monotherapy in this situation, and that the use of opioids in such patients is not indicated.
Rotator Cuff Tears
–A two year follow-up of a randomized trial comparing three treatments for supraspinatus tears (physiotherapy, physiotherapy + acromioplasty, and rotator cuff repair + acromioplasty +physiotherapy) found no significant pain or function differences among the three groups. However, mean tear size was significantly smaller in the cuff-repair group than in the other two.
–A meta-analysis3 investigating the use of cannabinoids for managing chronic pain and spasticity concluded that those substances reduced pain and spasticity more than placebo, but the benefits came with an increased risk of side effects such as dizziness, nausea, confusion, and loss of balance.
–A randomized controlled trial4 comparing a phone-based cognitive-behavioral/physical therapy (CBPT) program to standard education following lumbar spine surgery found that patients in the CBPT group had greater decreases in pain and disability and increases in general health and physical performance.

In the December 7, 2016 issue of JBJS, Krause et al. analyze data from a 2013 industry-sponsored RCT to investigate correlations between nonunions of hindfoot/ankle fusions indicated by early postoperative computed tomography (CT) and subsequent functional outcomes. Whether nonunion was assessed by independent readings of those CT scans at 24 weeks or by surgeon composite assessments at 52 weeks, patients with failed healing had lower AOFAS, SF-12, and Foot Function Index scores than those who showed osseous union.
This study suggests that a CT should be obtained from patients who are at least 6 months out from a surgical fusion and are not progressing in terms of activity-related pain and function. Depending on the specific CT findings, a repeat attempt at bone grafting, with the possible addition of bone-graft substitute and/or possible modification of internal fixation, may be warranted to forestall later clinical problems.
Krause et al. imply that trusting plain radiographs that show no indication of fusion failure is not acceptable when patient pain and function do not improve in a timely fashion. Conversely, they conclude that their findings do not support “the concept of an asymptomatic nonunion (i.e., imaging indicating nonunion but the patient doing well),” because nonunions identified early by CT eventually resulted in worse clinical outcomes. The authors also noted that obesity, smoking, and not working increased the risk of nonunion, corroborating findings from earlier studies.
While advanced imaging such as CT is not necessary in foot/ankle fusion patients who are improving in terms of function, pain, and swelling , this study stresses the importance of achieving union following these fusion procedures.
Marc Swiontkowski, MD
In a November 16, 2016 JBJS study whose findings have implications for both research and practice, Katz et al. analyzed data from the MeTeOR trial to answer two questions:
- What prompts patients with meniscal tears and knee osteoarthritis who are randomized to physical therapy (PT) in trials comparing PT to arthroscopic partial meniscectomy (APM) to cross over from nonoperative therapy to APM?
- Do those who cross over to APM receive symptom relief that’s comparable to those originally randomized to APM?
After careful multivariate analysis of 48 patients who crossed over in the MeTeOR trial (representing 27% of those originally randomized to PT), the authors identified two factors associated with a higher likelihood of crossover: a baseline WOMAC Pain Score of ≥40 and symptom duration of <1 year. The authors also found that patients who crossed over to APM were just as likely to experience improvement in pain scores as those originally randomized to APM.
From a research standpoint, the authors suggest that future investigators may wish to make “special efforts” to keep patients who present with severe pain and relatively short symptom duration in nonoperative therapy. Clinically, Katz et al. say the findings “underscore the emerging treatment recommendation…to try a PT regimen before opting for APM.”
