BACKGROUND AND OBJECTIVE In 2010, the Lithuanian Association of Arhtroplasty was established and on January 1, 2011, initiated a national study of all reoperations after total knee (TKR) and total hip replacement (THR) in Lithuania. The aim of the study was to investigate the revision rates after TKR and THR at two years follow-up. MATERIALS AND METHODS Lithuanian patients undergoing primary ...

BACKGROUND In a prospective cohort study, we wanted to detect thresholds distinguishing between patients with a satisfactory and an unsatisfactory outcome after total knee replacement (TKR) based on Patient-Reported Outcome Measures (PROMs), namely the Oxford Knee Score (OKS), using patient satisfaction and patient-perceived function as global transition items. METHODS Seventy-three TKR patie...

Abstract Aim This study represents one of the largest clinical case series' evaluating long-term outcomes following surgical fixation tibial plateau fractures over a 10-year follow-up. The primary aim is to evaluate incidence TKR and risk-factors associated with poor outcomes. Method Patients receiving between 2008 – 2012 were included. Those requiring arthroplasty or endoprosthesis post-injury...

An appropriate positioning of a total knee replacement (TKR) is a prerequisite for a good functional outcome and a prolonged survival (1). Navigation systems may facilitate the proper positioning of the implants (2). Patient specific templates have been developed to achieve at least the same accuracy than conventional instruments at a lower cost (3). The learning curve of such systems has not y...

Background To determine unicompartmental (UKR) and total knee replacement (TKR) revision rates, compare UKR rates with what they would have been had received TKR instead, assess subsequent re-revision 90-day mortality rates. Methods Using National Joint Registry data, we estimated Flexible parametric survival modeling (FPM) was used to model failure in make estimates for UKR. Kaplan-Meier were ...

background few studies have focused on patients’ characteristics that affects acute kidney injury (aki) after total knee replacement surgery (tkr). objectives the primary objective of this retrospective study was to identify patients’ characteristics associated with aki after tkr. patients and methods between january 2008 and december 2009, 659 patients with a mean age of 67.1 years (range, 39-...

A 3D finite element model has been developed to study the mechanics of total knee replacements (TKRs). In particular, this study looked at the effects of certain design parameters on the stresses found in the meniscal insert component of a TKR. A primary reason for the failure of TKRs is failure of the meniscal insert. The meniscal insert is made from Ultra High Molecular Weight Polyethylene (U...

BACKGROUND Surgical pain is managed with multi-modal anaesthesia in total hip replacement (THR) and total knee replacement (TKR). It is unclear whether including local anaesthetic infiltration before wound closure provides additional pain control. METHODS We performed a systematic review of randomised controlled trials of local anaesthetic infiltration in patients receiving THR or TKR. We sea...

Our study has determined the response of C-reactive protein (CRP) after total knee replacement (TKR). The peak level occurs on the second postoperative day and is significantly greater than that after total hip replacement (THR). The level returns to normal at similar times after both procedures. The physiological response to TKR as measured by the area under the CRP/time curve is significantly...
