Nowadays, chronic deep periprosthetic joint infections (PJIs) are typically treated with 2-stage exchange arthroplasty, but what about acute PJIs? In the December 6, 2017 edition of JBJS, Bryan et al. report on a retrospective cohort study of acute infections after hip arthroplasty. The results suggest we’ve come a long way in identifying patients with early infections and that contemporary irrigation-and-debridement protocols are more successful than older methods.
The researchers studied 6-year outcomes in 90 hips that had undergone either total or hemiarthroplasty and that were determined to have either acute early postoperative infections (n=66) or acute hematogenous infections (n=24). All the infected hips were managed with either irrigation, debridement, and modular head and liner exchange (70%) or with irrigation and debridement alone (30%). The authors stratified the patients into those without comorbidities (A), those with 1 or 2 comorbidities (B), and those with >2 comorbidities (C). Postoperatively, patients were treated with broad-spectrum intravenous antibiotics, followed by targeted therapy administered by infectious disease specialists.
Of the 90 acute infections, failure—defined as uneradicated infection, subsequent removal of any component for infection, unplanned second wound debridement for ongoing infection, or infection-related mortality—occurred in 15 hips (17%). Of those 15, 9 required component removal. The chances of treatment failure were slightly higher in cases of hematogenous infection (21%), compared with acute early postoperative infection (15%), but that difference was not statistically significant. Significant comorbidity-related failure-rate differences were found: failure occurred in 8% of the grade-A patients, 16% of grade-B patients, and 44% of grade-C patients. The most common infecting organism was methicillin-sensitive Staphylococcus aureus (MSSA).
From this overall 6-year success rate of 83%, the authors conclude that “with modern inclusion criteria for acute infection, modern surgical techniques, and modern antibiotic therapy…the rate of success was higher than in most historic reports.”
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 15, 2017 Specialty Update on Orthopaedic Rehabilitation, summarized the most clinically compelling findings from among the nearly 50 noteworthy studies summarized in the article.
–Results from a retrospective review1 of patients with noncancer pain highlighted that the risks of long-acting opioids extend beyond overdose, and include increased risks of cardiovascular death and all-cause mortality.
–A randomized prospective trial2 comparing celecoxib, ibuprofen, and naproxen for treating arthritis pain found no significant difference in the hazard ratios for those medications as related to risk of cardiovascular events.
Cost & Quality
–An assessment of a value-improvement initiative3 that examined hip and knee arthroplasty and hip fracture outcomes in a large regional health-care system found reduced costs and improvements in quality of care from 2012 to 2016.
–A literature review4 of 7 studies determined that the long-term cognitive and neurogenerative effects of multiple concussions in patients ≤17 years of age remain inconclusive.
–A randomized trial5 found no difference between anesthetic-only and anesthetic-plus-steroid epidural injections in the treatment of lumbar spinal stenosis.
–A prospective cohort study6 by the MOON Shoulder Group found that the strongest predictor of failure of nonoperative treatment for symptomatic atraumatic rotator cuff tears was lower patient expectations that such treatment would be successful. Pain level, duration of symptoms, and tear anatomy did not predict treatment failure.

In the December 6, 2017 issue of The Journal, Arshi et al. report on a detailed analysis of a large administrative database, looking specifically at one-year complications associated with outpatient versus standard inpatient knee replacement. This type of analysis is crucial because of the rapidly growing interest in outpatient joint replacement among patients, payers, and the orthopaedic community.
The data convince me that these outpatient procedures should proceed, but with a little more caution. Although the absolute complication rates in both surgical settings were very low, after adjusting for age, sex, and comorbidities, the authors found a higher relative risk of several surgical and medical complications among outpatients—including component failure, infection, knee stiffness requiring manipulation under anesthesia, and deep vein thrombosis.
One important element that is lacking in this analysis is adjustment for surgeon/hospital volume. We know from important work by Katz and others that patients managed at centers and by surgeons with greater volumes of total knee replacement have lower risks of perioperative adverse events.
These results from Arshi et al. are definitely not a call to stop the expansion of outpatient joint replacement protocols. Instead, I think this study should prompt every joint-replacement center to analyze its risk-adjusted inpatient and outpatient outcomes—and to ensure, as these authors emphasize, that outpatients receive the same level of attention to rehabilitation, antibiotic administration, and thromboprophylaxis as inpatients.
Enhancing outpatient knee-replacement protocols will serve local communities well, and the nationwide orthopaedic community will receive further confirmation that outpatient joint replacement is a move in the right direction.

In 2015, JBJS launched an “article exchange” collaboration with the Journal of Orthopaedic & Sports Physical Therapy (JOSPT) to support multidisciplinary integration, continuity of care, and excellent patient outcomes in orthopaedics and sports medicine.
During the month of December 2017, JBJS and OrthoBuzz readers will have open access to the JOSPT article titled “Hip Abductor Muscle Volume and Strength Differences Between Women With Chronic Hip Joint Pain and Asymptomatic Controls.”
This cross-sectional study demonstrated that women with chronic hip joint pain had larger gluteal muscle volume but decreased hip abductor strength, compared to asymptomatic controls.
An estimated 300,000 ACL surgeries are performed in the US annually, at an estimated cost of up to $1 billion, but we still have many unanswered questions about patient satisfaction after these procedures. Among them:
- Does the cost of postoperative physical therapy affect patient satisfaction?
- What are the rates and predictors of return to play after ACL reconstruction? Does graft choice play a role?
- What is the relationship between return to play and patient satisfaction?
On Wednesday, December 13, 2017 at 8:00 PM EST, the Journal of Orthopaedic & Sports Physical Therapy (JOSPT) and The Journal of Bone & Joint Surgery (JBJS) will host a complimentary* LIVE webinar that addresses these and other important questions.
JOSPT co-author Caitlin J. Miller, PT, DPT and JBJS co-author Benedict U. Nwachukwu, MD, MBA, will discuss findings from their respective studies, and the webinar will include additional insights from Mark V. Paterno, PT, PhD, MBA, SCS, ATC, and Elizabeth Matzkin, MD. Moderated by Tara Jo Manal, PT, DPT, OCS, SCS, FAPTA, the webinar will conclude with a live Q&A session between the audience and panelists.
Seats are limited so REGISTER NOW.
*All registrants will have free access to the webinar for 24 hours following the live broadcast.
