INTRODUCTION Total knee arthroplasty (TKA) is increasingly being performed. Distal femur periprosthetic fracture is a potentially catastrophic complication following TKA and existing data document substantial distal femur bone mineral density (BMD) loss following TKA. However, distal femur BMD is virtually never measured clinically as no consensus approach exists. This pilot study's purpose was to define regional BMD variation throughout the femur, suggest standard dual-energy X-ray… Expand
DXA evaluation of femoral bone mineral density and cortical width in patients with prior total knee arthroplasty
TLDR
Distal femur BMD can be reproducibly measured using DXA and is ~ 10% lower on the TKA leg than on the non-operated leg, and medial and lateral cortices are thinner at the 25% ROI. Expand
Three dimensional bone mineral density changes in the femur over 1 year in primary total hip arthroplasty patients.
TLDR
The results showed that most of the bone loss was located around the Lesser Trochanter and some bone density gain at the distal tip of the implant and the study showed no correlation of bone loss with age. Expand

TLDR
Lower values were observed in the surgical leg, consistent with the bone loss that follows TKA, and this pilot study documents the feasibility of reproducibly obtaining distal femur TBS ORTHO values. Expand

Distal femoral bone mineral density after total knee arthroplasty: a comparison with general bone mineral density
TLDR
It is found that a significant periprosthetic distal femoral bone resorption occurred after TKA and less than 1% difference in BMD of both femoral necks and the lumbar spine on average between the preoperative and 1 year follow-up measurements (not significant). Expand
Periprosthetic tibial bone mineral density changes after total knee arthroplasty
TLDR
Tibial metaphyseal periprosthetic bone is remodeled after TKA due to mechanical axis correction, resulting in more balanced bone stock below the tibial tray, related to good component survival in this medium-term follow-up. Expand
Periprosthetic femoral bone loss after total knee arthroplasty: 1-year follow-up study of 69 patients.
TLDR
Bone loss was most rapid during the first 3 months after TKA, and it is suggested that the observed periprosthetic bone loss was mainly the result of prosthesis-related stress-shielding. Expand
A cemented mobile-bearing total knee replacement prevents periprosthetic loss of bone mineral density around the femoral component: a matched cohort study.
TLDR
Findings show that a cemented mobile-bearing TKR has a favourable effect on the BMD of the distal femur after TKR in the short term, and further study is required to determine the long-term effects. Expand
Teriparatide Administration Increases Periprosthetic Bone Mineral Density After Total Knee Arthroplasty: A Prospective Study.
TLDR
Teriparatide may be a reasonable treatment option for osteoporotic patients to preserve or improve periprosthetic BMD after TKA to inhibit BMD loss in the femoral and tibial side. Expand
Modulation and Predictors of Periprosthetic Bone Mineral Density following Total Knee Arthroplasty
TLDR
It is assumed that a large muscle mass with accompanying distribution of high mechanical load in the bones can contribute to local changes of periprosthetic BMD and concrete recommendations for preventing peri-implant bone loss therefore include exercises which have the aim of maintaining or building up muscle mass.

TLDR
The most significant BMD decrease was observed in the period between 5 and 12 weeks after the knee joint arthroplasty, which is a result of the postoperative increased bone resorption and decreased patient motor activity. Expand
Osteodensitometry measurements of periprosthetic bone using dual energy X-ray absorptiometry following total knee arthroplasty
TLDR
Results achieved in the present study demonstrate that the fundamental classification in defined ROI proved to be functional and effective, and significant gender-specific associations regarding changes in bone density were established. Expand
Outcome of periprosthetic distal femoral fractures following knee arthroplasty.
TLDR
Evaluating a consecutive series of periprosthetic supracondylar femoral fractures treated with locked periarticular plate fixation found indirect reduction and submuscular plate insertion technique reduce nonunion risk, and notching of the anterior femoral cortex should be avoided. Expand
Functional outcome of total knee arthroplasty after periprosthetic distal femoral fracture.
TLDR
It is found that periprosthetic distal femoral fracture after TKA worsens functional outcomes at the medium term, but arthroplasty complication and survival rates were similar in both groups. Expand
