Translation and cultural adaptation of the Turkish Lysholm knee scale: ease of use, validity, and reliability.
The Lysholm knee scale, first published in 1982, is an eight-item questionnaire designed to evaluate patients after knee ligament injury. However, as a tool developed in English, its use as a validated instrument has been limited to English-language populations. ⋯ The Turkish version of the Lysholm knee scale is quickly administered, valid, and reliable, and can be used for patients with various knee disorders.

Comparative StudyTreatment and displacement affect the reoperation rate for femoral neck fracture.
Femoral neck fractures (FNFs) comprise 50% of geriatric hip fractures. Appropriate management requires surgeons to balance potential risks and associated healthcare costs with surgical treatment. Treatment complications can lead to reoperation resulting in increased patient risks and costs. Understanding etiologies of treatment failure and the population at risk may decrease reoperation rates. ⋯ Overall, hemiarthroplasty resulted in fewer reoperations versus internal fixation and displaced fractures underwent reoperation more than nondisplaced. Our data suggest there are fewer reoperations when treating elderly patients with displaced FNFs with hemiarthroplasty than with internal fixation.

Comparative StudyOlder age increases short-term surgical complications after primary knee arthroplasty.
Age is a known risk factor for complications after knee arthroplasty; however, age-related risks for a variety of complications of total and partial knee arthroplasties have not been well quantified. ⋯ Age is an important independent predictor of surgical complications after knee arthroplasties. Surgeons can share these quantified age-specific risks with patients to guide management decisions.

Does radiographic beam angle affect the radiocapitellar ratio measurement of subluxation in the elbow?
Radial head alignment is the key to determine elbow reduction after treatment of subluxations or Monteggia fractures. The radiocapitellar ratio (RCR) quantifies the degree of subluxation, by evaluating radial head alignment with the capitellum of the humerus; this ratio is reproducible when measured on true lateral radiographs of nonsubluxated elbows. However, the impact of beam angulation on RCR measurement is unknown. ⋯ Identification of a subluxated elbow could be made on any lateral radiograph with a beam angulation deviation of as much as 20°. This suggests that the RCR is a useful diagnostic tool for clinical and research purposes, although for subluxated elbows, it is important to pay careful attention to the inferosuperior position of the C-arm.

pHEMA-nHA encapsulation and delivery of vancomycin and rhBMP-2 enhances its role as a bone graft substitute.
Bone grafts are widely used in orthopaedic procedures. Autografts are limited by donor site morbidity while allografts are known for considerable infection and failure rates. A synthetic composite bone graft substitute poly(2-hydroxyethyl methacrylate)-nanocrystalline hydroxyapatite (pHEMA-nHA) was previously developed to stably press-fit in and functionally repair critical-sized rat femoral segmental defects when it was preabsorbed with a single low dose of 300 ng recombinant human bone morphogenetic protein-2/7 (rhBMP-2/7). ⋯ The elasticity, osteoconductivity, and rhBMP-2/vancomycin delivery characteristics of pHEMA-nHA may benefit orthopaedic reconstructions or fusions with enhanced safety and efficiency and reduced infection risk.
