BACKGROUND Limb salvage following resection of a tumor in the proximal part of the humerus poses many challenges. Reconstructive options are limited because of the loss of periarticular soft-tissue stabilizers of the glenohumeral joint in addition to the loss of bone and articular cartilage. The purpose of this study was to evaluate the functional outcome(More)
Surgery for the unstable total knee arthroplasty requires a deep understanding of the causes and a plan that specifically addresses them. Isolated ligament reconstructions and polyethylene insert exchanges generally do not work. Patients may experience "buckling" from pain, flexion contracture, recurvatum, or patellar problems. True mechanical instability(More)
BACKGROUND Multiple cell-signaling ligands and receptors-including vascular endothelial growth factor (VEGF), insulin-like growth factor (IGF), endothelial growth factor (EGF), v-akt murine thymoma viral oncogene homolog (AKT), platelet-derived growth factor (PDGF), mitogen-activated protein kinase (MAPK), and 70-kilodalton (kD) protein S6 kinase (p70S6(More)
Wound problems can often be prevented with careful planning. When transverse incisions are used for knee surgery many years prior to any anticipated knee arthroplasty, no major problems are typically encountered with a conventional, anterior longitudinal incision. We recommend lateral incisions (eg, after a previous lateral tibial plateau fracture) be(More)
We performed a retrospective study of the radiographic position of femoral and tibial components in a series of revision total knee arthroplasties using diaphyseal-engaging, press fit, modular stems. Fifty-two consecutive revision cases were performed. Femoral and tibial component alignment was measured preoperatively and postoperatively. The canal-filling(More)
UNLABELLED We propose a surgical technique for structural allograft reconstitution of the diaphysis of long bones, maximizing surface contact between host and allograft bone. This method, analogous to a telescope, overlaps the graft and host bone, theoretically increasing bone surface contact substantially. We report the outcome of 22 telescoped allograft(More)

This represents a 15-year to 19-year follow-up of 100 Insall-Burstein-I posterior-stabilized knee prostheses implanted in 86 patients from 1986 to 1989 and originally reported at 10 to 12 years (Thadani et al, 2000). In the original cohort, 6 failures occurred by 10 years. At 15 to 19 years, 55 patients (66 knees) had died; 18 patients were followed with(More)
