Survival and failure analysis of 167 medial opening wedge high tibial osteotomy with a locking titanium plate.

Introduction: This retrospective study investigated the survival rate and complications of medial opening wedge high tibial osteotomy (MOWHTO) with a precountered titanium locking plate.

Hypothesis: Advanced age (≥50years), gender, body mass index (BMI), type of osteotomy cut (monoplanar or biplanar), osteoarthritis (OA) grade, the use of bone grafting or substitution and preoperative hip-knee-ankle (HKA) have impact on MOWHTO survival.

Material And Methods: A total of 167 knees (155 patients) were consecutively operated during the study period of 01.

Long-term follow-up results of medial opening wedge high tibia osteotomy with a pre-countered non-locking steel plate.

Introduction: This retrospective study investigated the long-term follow-up results of medial opening wedge high tibial osteotomy (MOWHTO) with a pre-countered non-locking steel plate implant (Puddu plate = PP) used for medial knee osteoarthrosis (OA) treatment.

Materials And Methods: Consecutive 70 MOWHTOs (66 patients) were performed between 01.01.

Health-Related Quality of Life after Hip and Knee Arthroplasty Operations.

Background And Objective: The aim of this study was to investigate the health-related quality of life before and after a hip and a knee arthroplasty operation using a 15D instrument and to compare these scores to the Finnish control population 15D scores.

Methods: The pre- and post-operative data of 15D were prospective collected from the patients undergoing total hip arthroplasty or total knee arthroplasty at the Kuopio University Hospital. Post-operative data were collected at 6 and 12 months after the operation.

Periprosthetic bone mineral density changes after unicondylar knee arthroplasty.

Background: Unicompartmental knee arthroplasty (UKA) has received renewed interest in the last decade. UKA involves minor injury to soft tissues, limited removal of bone and delicate preservation of knee anatomy and geometry. In theory, UKA provides an opportunity to restore post-surgical knee kinematics to near normal.

Bone mineral density in the proximal femur and contralateral knee after total knee arthroplasty.

Osteoarthrosis (OA) is often associated with pain and disability, which are relieved after total knee arthroplasty (TKA), but the nature of bone changes associated with OA is controversial. We examined preoperative hip and contralateral knee bone mineral density (BMD) in patients requiring TKA and monitored the BMD changes postoperatively. Sixty-nine patients, scheduled to have TKA for osteoarthrotic knees, had both hips and contralateral knee BMD measured by dual-energy X-ray absorptiometry (DXA) at the time of operation (baseline) and at 1 yr after operation.

Periprosthetic tibial bone mineral density changes after total knee arthroplasty: one-year follow-up study of 69 patients.

Background: The critical structure supporting the prosthetic components in total knee arthroplasty (TKA) is tibial trabecular bone. The quality of tibial bone can be evaluated by bone mineral density (BMD) measurements.

Patients And Methods: We prospectively measured changes in BMD in the proximal tibia after cemented TKA in osteoarthrotic knees.

Periprosthetic femoral bone loss after total knee arthroplasty: 1-year follow-up study of 69 patients.

The clinical survival of joint arthroplasties is related to the quality of the surrounding bone environment. Bone mineral density (BMD) is an important measure of bone strength and quality. The aim of this prospective study was to measure the quantitative changes in BMD in the distal femur after cemented total knee arthroplasty (TKA) in osteoarthrotic knee joints.

Periprosthetic bone loss after cemented total hip arthroplasty: a prospective 5-year dual energy radiographic absorptiometry study of 15 patients.

In this prospective 5-year study, we determined the periprosthetic bone loss after cemented total hip arthroplasty (THA) in 15 patients using dual energy X-ray absorptiometry (DXA). A reduction in the periprosthetic bone mineral density (BMD) of 5-18% occurred in all Gruen regions, or regions of interest (ROI), during the first 3 months after THA. The bone loss continued up to 6 months in almost all ROIs.
