Dynamic intraligamentary stabilization of anterior cruciate ligament repair: hardware removal has no effect on knee laxity at 2-year follow-up.
Dynamic intraligamentary stabilization (DIS) stabilizes the knee joint during anterior cruciate ligament (ACL) healing. After 6 months, tibial hardware removal is offered to the patients if local discomfort at the implant site is present. ⋯ Case-control study, Level III.

Low dislocation rate of Saturne®/Avantage® dual-mobility THA after displaced femoral neck fracture: a cohort study of 966 hips with a minimum 1.6-year follow-up.
Dislocation is a serious and common complication and a great concern with the use of total hip arthroplasty (THA) when treating displaced femoral neck fracture (FNF). Dual-mobility (DM) THA might reduce the dislocation risk. We aim to report the dislocation and revision rate of primary DM THA in patients with displaced FNF. ⋯ Overall, DM THA inserted via PLA results in an acceptable dislocation risk and low revision rate in fragile, old patients with acute FNF fracture, regardless of mental status. A unique complication in DM THA is IPD, which requires an immediate open reduction surgery.

Case ReportsIntraoperative ultrasound-guided reduction of femoral shaft fractures using intramedullary nailing: a technical note.
Intramedullary (IM) nailing is the preferred method for treatment of femoral shaft fractures. However, for the surgical staff and the patients, exposure to large dose of X-rays is inevitable during the procedure. In this paper, a new technique based on ultrasound is proposed to guide the reduction of femoral fractures, reducing radiation exposure. ⋯ Intraoperative ultrasound can guide the reduction of femoral shaft fracture using IM nailing, and reduce the radiation exposure of medical staff and patients.

Correlation of histological and microbiological findings in septic and aseptic knee implant failure.
The Musculoskeletal Infection Society (MSIS) has defined specific clinical and laboratory criteria for the diagnosis of periprosthetic joint infection (PJI). In this study we assessed the diagnostic utility of MSIS microbiological and histological criteria for PJI in 138 cases of septic and aseptic knee implant failure. ⋯ Knee PJI is more often identified by current MSIS histological than microbiological criteria. A significant proportion of SIF cases show either no growth or growth of an organism from only one sample. AIF is identified by both MSIS microbiological and histological criteria. Correlation of clinical, radiological and laboratory findings is required for the diagnosis of knee PJI.

Outcomes in 385 developmental dysplastic hips requiring total hip arthroplasty.
Patients with developmental dysplasia of the hip (DDH) require special surgical considerations for total hip arthroplasty (THA). Despite the difficulties posed by the population's anatomical abnormalities, few large evaluations of postoperative outcomes exist. This study seeks to characterize outcomes following primary THA among patients diagnosed with DDH. ⋯ Despite their surgical complexity, DDH patients on average have notably low rates of revision and dislocation. Longer follow-up is needed to better assess outcomes after THA in this complex patient population.
