To map literature on prognostic factors related to outcomes of revision total knee arthroplasty (rTKA), to identify extensively studied factors and to guide future research into what domains need further exploration. We performed a systematic literature search in MEDLINE, Embase, and Web of Science. The search string included multiple synonyms of the following keywords: "revision TKA", "outcome" and "prognostic factor". We searched for studies assessing the association between at least one prognostic factor and at least one outcome measure after rTKA surgery. Data on sample size, study design, prognostic factors, outcomes, and the direction of the association was extracted and included in an evidence map.Aims
Methods
Aseptic loosening is the most common cause of failure following cemented total knee arthroplasty (TKA), and has been linked to poor cementation technique. We aimed to develop a consensus on the optimal technique for component cementation in TKA. A UK-based, three-round, online modified Delphi Expert Consensus Study was completed focusing on cementation technique in TKA. Experts were identified as having a minimum of five years’ consultant experience in the NHS and fulfilling any one of the following criteria: a ‘high volume’ knee arthroplasty practice (> 150 TKAs per annum) as identified from the National joint Registry of England, Wales, Northern Ireland and the Isle of Man; a senior author of at least five peer reviewed articles related to TKA in the previous five years; a surgeon who is named trainer for a post-certificate of comletion of training fellowship in TKA.Aims
Methods
This study aims to identify the top unanswered research priorities in the field of knee surgery using consensus-based methodology. Initial research questions were generated using an online survey sent to all 680 members of the British Association for Surgery of the Knee (BASK). Duplicates were removed and a longlist was generated from this scoping exercise by a panel of 13 experts from across the UK who provided oversight of the process. A modified Delphi process was used to refine the questions and determine a final list. To rank the final list of questions, each question was scored between one (low importance) and ten (high importance) in order to produce the final list.Aims
Methods
A patient-centred approach, usually achieved through shared decision
making, has the potential to help improve decision making around
knee arthroplasty surgery. However, such an approach requires an
understanding of the factors involved in patient decision making.
This review’s objective is to systematically examine the qualitative literature
surrounding patients’ decision making in knee arthroplasty. A systematic literature review using Medline and Embase was conducted
to identify qualitative studies that examined patients’ decision
making around knee arthroplasty. An aggregated account of what is
known about patients’ decision making in knee arthroplasties is
provided.Objectives
Methods
Previous genome-wide association studies (GWAS) have reported significant association of the single nucleotide polymorphism (SNP) rs8044769 in the fat mass and obesity-associated gene (FTO) with osteoarthritis (OA) risk in European populations. However, these findings have not been confirmed in Chinese populations. We systematically genotyped rs8044769 and evaluated the association between the genetic variants and OA risk in a case-controlled study including 196 OA cases and 442 controls in a northern Chinese population. Genotyping was performed using the Sequenom MassARRAY iPLEX platform.Objectives
Methods
Obesity is an epidemic across both the developed
and developing nations that is possibly the most important current
public health factor affecting the morbidity and mortality of the global
population. Obese patients have the potential to pose several challenges
for arthroplasty surgeons from the standpoint of the influence obesity
has on osteoarthritic symptoms, their peri-operative medical management,
the increased intra-operative technical demands on the surgeon,
the intra- and post-operative complications, the long term outcomes
of total hip and knee arthroplasty. Also, there is no consensus
on the role the arthroplasty surgeon should have in facilitating
weight loss for these patients, nor whether obesity should affect
the access to arthroplasty procedures.
