Comparative Study
Wear Characteristics of Conventional Ultrahigh-Molecular-Weight Polyethylene Versus Highly Cross-Linked Polyethylene in Total Ankle Arthroplasty.
The aim of this study was to compare the polyethylene wear rate, particle size, and particle shape of primary semiconstrained, fixed-bearing, bone-sparing total ankle arthroplasty using conventional ultrahigh-molecular-weight polyethylene (CPE) versus highly cross-linked polyethylene (HXLPE) by applying a level walking input using a joint simulator. ⋯ Polyethylene wear particles have been linked to osteolysis after total ankle arthroplasty. There is no consensus on the importance of highly cross-linked polyethylene in total ankle arthroplasty with regard to implant wear. This is the first nonindustry study to compare the polyethylene wear rate, particle size, and particle shape of fixed-bearing total ankle arthroplasty conventional polyethylene versus highly cross-linked polyethylene. The lower wear rate and different particle size/morphology of highly cross-linked polyethylene could be beneficial in vivo to decrease osteolysis.

Comparative Study
Comparison of 2-Octyl Cyanoacrylate Topical Skin Adhesive and Simple Interrupted Nylon Sutures for Wound Closure in Ankle Fracture Surgery.
Multiple options are available for closure of incisions in ankle fracture surgery. The aim of our study was to compare postoperative outcomes between conventional simple interrupted nylon sutures and 2-octyl cyanoacrylate as a topical skin adhesive to close the incision after ankle fracture surgery. ⋯ Level III, retrospective comparative study.

Acute hematogenous periprosthetic joint infection (PJI) is defined in the literature as infection diagnosed and treated within 2 to 4 weeks from the onset of symptoms. In total hip and knee arthroplasty, irrigation and debridement (I&D) and polyethylene exchange with component retention has been studied extensively. However, there is minimal literature evaluating this treatment method for PJI in total ankle arthroplasty (TAA). The purpose of this study was to evaluate both the clinical and patient-reported outcomes and survivorship of TAA acute hematogenous PJIs treated with I&D and polyethylene exchange. ⋯ Level IV, case series.

We initiated a retrospective study on ankle fractures to assess (1) the time needed for fracture union; (2) the incidence of adverse radiographic outcomes (AROs); (3) factors that might lead to AROs; and (4) whether AROs were associated with worse function and higher incidence of post-trauma osteoarthritis (PTOA). ⋯ Level III, retrospective cohort study.

In an effort to minimize narcotic analgesia and its potential side effects, anti-inflammatory agents offer great potential provided they do not interfere with bone healing. The safety of ketorolac administration after foot and ankle surgery has not been well defined in the current literature. The purpose of this study was to report clinical healing and radiographic outcomes for patients treated with a perioperative ketorolac regimen after open reduction and internal fixation (ORIF) of ankle fractures. ⋯ Level IV, case series.
