Object: Although pain relief is a primary goal of a total knee arthroplasty (TKA) and partial knee arthroplasty (PKA), a significant number of arthroplasty patients experience unexplained pain. This study attempts to determine preoperative or intraoperative factors that may predict pain after knee arthroplasty. Methods: 2585 primary TKAs and 423 PKAs were performed between 1993 and 2013. Infect...

Background: Knee range of motion is an essential outcome measure following total knee arthroplasty and it is important to measure this outcome with a simple and accurate tool. Measurement from digital photographs could provide a superior clinical alternative to the common goniometer as devices for capturing digital photographs are becoming more accessible, measurement accuracy is assisted with ...

INTRODUCTION The use of patient reported outcome measures (PROMs) for four elective operations is mandatory in the English NHS from April 2009. In view of some scepticism by some clinicians as to the validity of PROMs, our aim was to explore the relationship between patients' and clinicians' reports of health status before and after knee arthroplasty. METHODS A secondary analysis of linked da...

BACKGROUND Previous osteotomy may compromise subsequent knee replacement, but no guidelines considering knee arthroplasty after prior osteotomy have been developed. We describe a systematic review of non-randomized studies to analyze the effect of high tibial osteotomy on total knee arthroplasty. METHODS A computerized search for relevant studies published up to September 2007 was performed i...

Polyethylene (PE) has been used extensively in knee arthroplasty since the mid 20th century. Progress in material manufacturing and processing has led to newer polyethylenes over last few decades with different material properties. It has been established that PE wear in knee arthroplasty causes particle induced osteolysis which is the main reason for late failure and requires revision surgery....

Improved pain management techniques and accelerated rehabilitation programs are revolutionizing our patients' postoperative experience after total hip and knee arthroplasty. The process involves regional anesthesia with multimodal pain control using local periarticular injections in combination with enhanced patient education and accelerated rehabilitation provided by a dedicated team of surgeo...

In an attempt to reduce health care expenses, regulated competition between health care providers has been introduced in The Netherlands. As for total hip and knee arthroplasties, health care providers have to publish their prices to make them available for the insurance companies and the public. Eventually, competition between health care providers should result in optimal care for lower price...

Background: The role of wound drainage after total knee arthroplasty is still considered controversial as althoughclosed drainage systems have been believed to be effective in decreasing the post-operative complications, they couldalso facilitate the bleeding and increase the rate of transfusion and infection. We have conducted the current study tocompare the outcomes superficial subcutaneous, ...

The authors report three cases of unicompartmental knee arthroplasty (UKA), complicated with peri-operative periprosthetic fracture of the tibial plateau. The surgical technique was held responsible in all cases. The initial treatment was different in every case; all patients ultimately underwent revision total knee arthroplasty with a good functional outcome. The authors emphasise the importan...

INTRODUCTION Periprosthetic patellar fracture after total knee arthroplasty (TKA) is a rare complication. Their management can be very challenging with unpredictable results. Literature analysis showed few articles about this complication, but no publication has described the management of open patella fracture around total knee arthroplasty. CASE PRESENTATION We report a unique case of an op...
