Multicenter StudyThe effect of pain after total knee arthroplasty on the contralateral, nonreplaced knee.
Osteoarthritis is associated with a strong biomechanical component. Persistent pain in the index knee after total knee arthroplasty could lead to pain in the contralateral knee. The purpose of the present study was to examine whether a change in the natural history of pain in the contralateral knee was related to postoperative pain in the index knee. ⋯ Pain in the index knee at three months after total knee arthroplasty did not appear to predict a symptomatic increase in pain in the contralateral knee over two years of follow-up in our cohort. The contralateral knee did not require any additional clinical surveillance over and above the patients' reports on their symptoms.

Histological study of the influence of plasma rich in growth factors (PRGF) on the healing of divided Achilles tendons in sheep.
The use of plasma rich in growth factors (PRGF) has been proposed to improve the healing of Achilles tendon injuries, but there is debate about the effectiveness of this therapy. The objective of the present study was to evaluate the histological effects of PRGF, which is a type of leukocyte-poor platelet-rich plasma, on tendon healing. ⋯ Based on the findings in this animal model, PRGF infiltration may improve the early healing process of surgically repaired Achilles tendons.

Randomized Controlled Trial Comparative StudyDo the skills acquired by novice surgeons using anatomic dry models transfer effectively to the task of diagnostic knee arthroscopy performed on cadaveric specimens?
The use of surgical simulation in orthopaedic education is increasing; however, its ideal place within the training curriculum remains unknown. The purpose of this study was to determine the effectiveness of training novice surgeons on an anatomic dry model of the knee prior to training them to perform diagnostic arthroscopy on cadaveric specimens. ⋯ Previous training utilizing an anatomic dry knee model resulted in improved proficiency for novice surgeons learning to perform diagnostic knee arthroscopy on cadaveric specimens. A CTER of 0.2 suggests that dry models can serve as a useful adjunct to cadaveric training for diagnostic knee arthroscopy but cannot entirely replace it within the orthopaedic curriculum. Further work is necessary to determine the optimal amount of training on anatomic dry models that will maximize transfer effectiveness and to determine how well skills obtained in the simulated environment transfer to the operating room.

Randomized Controlled Trial Multicenter Study Comparative StudyTRIGEN INTERTAN intramedullary nail versus sliding hip screw: a prospective, randomized multicenter study on pain, function, and complications in 684 patients with an intertrochanteric or subtrochanteric fracture and one year of follow-up.
Both intramedullary nails and sliding hip screws are used with good results in the treatment of intertrochanteric and subtrochanteric fractures. The aim of our study was to assess whether use of the TRIGEN INTERTAN nail, as compared with a sliding hip screw, resulted in less postoperative pain, improved functional mobility, and reduced surgical complication rates for patients with an intertrochanteric or subtrochanteric fracture. ⋯ INTERTAN nails and sliding hip screws are similar in terms of pain, function, and reoperation rates twelve months after treatment of intertrochanteric and subtrochanteric fractures.
