Motivation: Snowfall is an important component of the Earth's precipitation and hydrological cycle. Remote measurements of frozen hydrometeor properties have been limited because coincident measurements of microphysical and electromagnetic properties of snowfall have rarely been available. Ground-based radars have been widely used to monitor snowfall(More)
To assess the potential recovery rate of a minimally invasive total hip replacement technique with minimal soft tissue disruption, an accelerated rehabilitation protocol was implemented with weightbearing as tolerated on the day of surgery. One hundred consecutive patients were enrolled in this prospective study. Ninety-seven patients (97%) met all the(More)
BACKGROUND Femoral stems with dual-taper modularity were introduced to allow additional options for hip-center restoration independent of femoral fixation in total hip arthroplasty. Despite the increasing availability and use of these femoral stems, concerns exist about potential complications arising from the modular neck-body junction. METHODS This was(More)
The effect of total knee arthroplasty (TKA) on the Insall-Salvati ratio (ISR) and the effect of the ISR on the outcome of TKA have not been clearly established. A retrospective review of 1055 primary TKAs performed in 1997 to 1998 was performed. Radiographic measurements were made preoperatively and postoperatively, and the ISR was calculated. Regression(More)
BACKGROUND There is a renewed interest in unicompartmental knee arthroplasty. The present report describes the minimum ten-year results associated with a unicompartmental knee arthroplasty design that is in current use. METHODS Sixty-two consecutive unicompartmental knee arthroplasties that were performed with cemented modular Miller-Galante implants in(More)
Decreased muscle damage is a reported benefit of minimally invasive surgical (MIS) approaches in total hip arthroplasty (THA). We compared the extent and location of muscle damage during THA using the MIS anterior Smith-Petersen and MIS posterior surgical approaches. THA was performed in six human cadavers (12 hips). One hip was assigned to the(More)
This study examined the role that flexion contracture plays in postoperative outcomes after total knee arthroplasty using a retrospective database review. The relationships between preoperative and postoperative knee extension, walking ability, stair climbing ability, Knee Society scores, pain scores, and knee function scores were studied in 5,622 knees. A(More)
There is a renewed interest in cementless total knee arthroplasty (TKA) due to improved biomaterials, desire for decreased surgical times and the potential increased longevity. Seventy-three cementless TKAs (AGC, Biomet, Warsaw, Ind) were performed from 1984 to 1986. All components were implanted without cement and without screws and obtained minimum 10(More)
The most common previously reported modes of failure of unicompartmental knee arthroplasty (UKA) in the first and second decades are polyethylene wear, progression of arthritis, and component loosening. The purpose of this study is to describe an early mechanism of failure of the medial UKA. Thirty-two consecutive revisions from UKA to total knee(More)
Excision of the fat pad is common in total knee arthroplasty to enhance surgical exposure. However, the effect of this has not been clearly established. A retrospective review of 1055 primary total knee arthroplasties was preformed in 720 patients from 1997 to 1998. Regression analysis was performed to determine the effect of excising the fat pad on(More)
