The Mayo metaphysical conservative femoral stem (Zimmer, Warsaw, Indiana) is a wedge-shaped implant designed to transfer loads proximally, reduce femoral destruction, and enable the preservation of bone stock in the proximal femur. Thus, it is a potentially preferred prosthesis for active, non-elderly patients who may require additional future surgeries. This retrospective case study analyzed the outcomes of consecutive patients who underwent total hip replacements with this stem between May 2001 and February 2013.

Methods: Seventeen TKA patients participated in the study. Patients received a biomechanical therapy AposTherapy).
Background: The articular surface replacement (ASR) total hip arthroplasty (THA) was recently recalled from the market due to high failure rates. This modality was used frequently by surgeons at our medical center.
Objectives: To assess the clinical and radiographic outcomes in patients following the surgery and determine the revision rate in our cohort.
The authors retrospectively reviewed 27 consecutive patients with 29 fractures of the distal femur treated with the new retrograde expandable nail. One 10-mm diameter nail that expands to 16 mm was used with the possibility of locking in the condylar area only. Retrieved data included single versus multiple injuries, fracture type, operation time, reaming or nonreaming, hospitalization and healing times, and intra- and postoperative complications.

Introduction: Templating is now the standard approach for preoperative planning of total joint replacement and fracture fixation. The aim of this study was to assess the accuracy of new software, TraumaCadâ„¢, for preoperative planning for total hip replacement.
Methods: This software enables the import and export of all picture archiving communication system (PACS) files from local working stations.
Background: The purpose of our investigation was to compare a digital templating system to conventional templating techniques when preoperatively planning for total hip arthroplasty.
Methods: We included 18 consecutive patients with primary osteoarthritis undergoing uncemented total hip arthroplasty in our study. At separate sittings, we independently conducted preoperative templating.

The purpose of this study was to describe the surgical technique, and evaluate and analyze the clinical outcomes of patients who underwent tibial tubercle realignment in our institution. Reported results of tibial tubercle transfer for patellofemoral malalignment vary considerably. Most authors rely mainly on the passive intraoperative patellar tracking test in determining the new location of the tibial tubercle.
View Article and Find Full Text PDFPurpose: The femoral head expandable peg offers a new concept of bone-device purchase treating proximal femur fractures. We describe the expansion influence on both the periimplant bone properties and the intraosseous pressure.
Methods: A 10 x 8 mm cannulated peg consisting of a stainless steel oval-shaped transversely sectioned rod was tested on 13 femoral heads retrieved from patients with subcapital fracture treated by hemiarthroplasty.
Objective: To evaluate and present our experience using the expandable nail system for the treatment of acute tibial shaft fractures.
Design: Retrospective study.
Setting: Two level-1 trauma centers-University teaching hospitals.
Background: Fresh osteochondral allograft transplantation is a treatment option for young patients with osteochondral lesions of the knee. The present study evaluated the surgical complexity of, and the prevalence of complications related to, total knee arthroplasty in patients who had had a previous osteochondral graft transplantation.
Methods: A retrospective analysis was performed on thirty-three consecutive patients (thirty-five knees) who underwent total knee arthroplasty from 1974 to 2000 after having had a previous transplantation of a fresh osteochondral allograft into the same knee.

Unlabelled: Posttraumatic osteochondral defects of the distal femur or proximal tibia pose a reconstructive challenge for the young active patient. Fresh osteochondral allografts have been used to reconstruct these defects and this report deals with the long-term clinical and radiographic follow-up in this patient population. This is a prospective nonrandomized study.

For post-traumatic defects recent advances in other techniques for cartilage repair and resurfacing have reduced the role of allograft tissue transplantation to defects larger than 3 cm in diameter and 1 cm in depth.A fresh osteochondral allograft that has been harvested from a donor within 24 h from death and preserved in 4 degrees C for up to 4 days shows 100% viability of the cartilage.

Structural corticocancellous allografts were used in 48 cases. Twenty-seven cases had no complications, 9 had medical complications, and 5 had complications related to femoral revision.

The goal of treatment is a pain-free range of motion of the knee that provides enduring function and enables a young patient to participate in a wide range of activities. The use of fresh osteochondral allograft transplantation for tibial plateau lesions has been well documented.
