Cross-cultural adaptation and validation of the Turkish version of Oxford hip score.
The purpose of this study was to translate the Oxford hip score (OHS) into Turkish and to evaluate the psychometric properties by testing the internal consistency, reproducibility, construct validity, and responsiveness in patients with hip osteoarthritis (OA). ⋯ The OHS-TR questionnaire is valid, reliable, and responsive for the Turkish-speaking patients with hip OA.

Redisplacement after reduction with intramedullary nails in surgery of intertrochanteric fracture: cause analysis and preventive measures.
During the implantation of intramedullary nail in surgery of intertrochanteric fracture, the fact that the originally satisfactory reduction may incur redisplacement remains a major concern. In this article, we will analyze the reasons of redisplacement and describe some methods that can improve the quality of reduction. ⋯ When reduction is achieved in the surgery of intertrochanteric fracture, surgeons tend to overlook the occurrence of redisplacement, or not to treat it that has emerged timely. Internal fixation in nonanatomic reduction may increase the likelihood of fixation failure postoperatively. For the importance of accurate reduction of the fracture, once redisplacement occurs during the surgery, some methods or tricks are applicable to it to restore the anatomic reduction.

Open debridement and prosthesis retention is a viable treatment option for acute periprosthetic joint infection after total knee arthroplasty.
Open debridement with prosthesis retention (ODPR) has been considered as a reasonable treatment option for acute periprosthetic joint infection (PJI) following total knee arthroplasty (TKA). However, multiple recent studies have challenged this contention. This study was undertaken to determine the success rate of ODPR, whether the success rate was affected by the ODPR timing or by the microorganisms. ⋯ ODPR should be considered as a viable treatment option for acute PJI following TKA. The promptness of ODPR is of paramount importance for success of ODPR, rather than the causative organism type or virulence.

Function and kinematics following unicondylar knee arthroplasty (UKA) have been reported to be close to the native knee. Gait, stair climbing and activities of daily living expose the knee joint to a combination of varus and valgus moments. Replacement of the medial compartment via UKA is likely to change the physiologic knee stability and its ability to respond to varus and valgus moments. It was hypothesized that UKA implantation would stiffen the knee and decrease range of motion in the frontal plane. ⋯ In UKA, the compressive anatomy is replaced by much stiffer components. This lack of medial compression and relative overstuffing leads to a tighter medial collateral ligament. This drives the trend towards a stiffer joint as documented by a decrease in frontal plane range of motion. Overstuffing should strictly be avoided when performing UKA.
