Study: Complications after Same-day Versus Rapid Hospital Discharge following TKA

A study published in the May 1 issue of the Journal of the AAOS ® determined complications after total knee arthroplasty (TKA) with same day versus longer discharge. Researchers evaluated 84,64 patients treated between 2007 to 2017 via the PearlDiver Database. Incidences of same-day (<24 hours), rapid (one to two days), and traditional (three to four days) discharge were 2.36 percent, 28.56 percent, and 69.08 percent, respectively. There were no significant differences in one-year complications and revision between same-day discharge and the other groups. After one year, rapid discharge patients were less likely to require reoperation or develop periprosthetic joint infection compared to those who were discharged traditionally.

Study: Bone-implant Stability Factors Predict Reoperation after Trochanteric Fracture Repair

A retrospective study published online in Injury evaluated the association between bone-implant stability factors and the rate of reoperation after surgery for geriatric trochanteric fractures. The study enrolled 390 patients aged ≥60 years who were treated with intramedullary nailing. Fifteen patients (3.8 percent) required reoperation. A3 fracture type and inadequate reduction quality were independent predictors of reoperation. Patients who required reoperation had significantly different T-score at the total hip and lumbar spine and cortical thickness index compared to patients who did not. Fractures with inadequate reduction and a fixation ratio ≤0.8 had the highest reoperation rate (9.3 percent).

A study published online in the Journal of Shoulder and Elbow Surgery assessed risk factors for intra- and postoperative complications and revision after total shoulder arthroplasty (TSA) or reverse TSA (RSTA). The researchers used an international database to identify 2,964 patients who underwent TSA and 5,616 who underwent RTSA patients. TSA was associated with significantly higher incidence of complications and revision compared to RTSA, though the TSA group had longer average follow-up than the RTSA group. Intra-operative complications were similar overall. Previous shoulder surgery was a risk factor of intra- and postoperative complications. Younger age was a risk factor of both postoperative complications and revision.

A retrospective study published online in Foot & Ankle International measured midterm outcomes of revision subtalar arthrodesis in 20 patients. Average follow-up was 48.93 months. Patient satisfaction and outcomes were measured via the American Orthopaedic Foot & Ankle Society Scale (AOFAS), the Foot and Ankle Outcome Score (FAOS), the Foot Function Index (FFI), and dynamic pedobarography. The overall fusion rate was 80 percent, and the remaining 20 percent of cases required additional surgery. Seventy percent of patients reported satisfaction with surgical results, 20 percent found the results “fair,” and 10 percent were not satisfied. FOAS, AOFAS, and FFI scores showed significant postoperative improvement overall.

A retrospective study published online in The Spine Journal evaluated how operative time during single-level anterior cervical discectomy and fusion (ACDF) impacts postoperative healthcare utilization and complications. The researchers used the American College of National Surgical Quality Improvement Program database to identify 24,593 ACDF procedures performed between 2012 and 2018. Operative time >100 minutes increased risk of length of stay (LOS) >2 days and non-home discharge, with a significantly higher risk if operative time was longer than 180 minutes. Operative time >200 minutes increased transfusion risk. Odds of LOS >2 days, non-home discharge, reoperation, and transfusion increased starting at an operative time >91 minutes.

Cato T. Laurencin, MD, PhD, FAAOS, Receives Kappa Delta Ann Doner Vaughn Award

This year, Cato T. Laurencin, MD, PhD, FAAOS, received the Kappa Delta Ann Doner Vaughn Award for developing a degradable matrix for bone tissue engineering. Dr. Laurencin is considered a pioneer of musculoskeletal regenerative engineering, and through his work found that a matrix system could facilitate bone regeneration, providing a framework onto which osteoblasts may bind to bridge bone defects. Dr. Laurencin and colleagues developed a novel sintered microsphere matrix resembling the structure of trabecular bone that allowed newly forming bone to occupy the pore structure while the matrix degraded, eventually leaving only the pore structure of the newly formed trabecular bone.

Submit Manuscripts for the 2022 Kappa Delta and OREF Clinical Research Awards

AAOS is soliciting manuscripts for the 2022 Kappa Delta Orthopaedic Research Awards and the Orthopaedic Research and Education Foundation (OREF) Clinical Research Award. Up to two $20,000 Kappa Delta awards (Elizabeth Winston Lanier Award and Ann Doner Vaughn Award), one $20,000 Kappa Delta Young Investigator award, and one $20,000 OREF award will be bestowed, provided manuscripts of requisite quality are submitted. Manuscripts should represent a large body of cohesive scientific work generally reflecting years of investigation. Manuscripts must be submitted by members (or candidate members) of AAOS, the Orthopaedic Research Society (ORS), the Canadian Orthopaedic Association, or the Canadian Orthopaedic Research Society. The awards will be presented at the AAOS 2022 Annual Meeting, and recipients will be invited to speak at the ORS 2022 Annual Meeting. Submissions are due by 11:59 p.m. CDT on July 1.
