BACKGROUND: The debate over the use of cemented or cementless fixation in total knee arthroplasty (TKA) has never stopped since cementless fixation was introduced. We undertook a systematic review and meta-analysis to evaluate the optimal mode of fixation (full-cementless vs. full-cemented) in TKA. METHODS: PubMed, Embase, and the Cochrane Library databases up to July 2017 were searched to identify randomised controlled trials (RCTs) and quasi-RCTs comparing full-cementless TKA and full-cemented TKA...

Background: Total hip (THA) and knee arthroplasty (TKA) are two of the most successful procedures in orthopedics. Current evaluation trends focus on patient-reported outcomes. We sought to compare the changing WOMAC scores from various time points from pre-operative to 1-year follow-up between separate THA and TKA cohorts. In addition, we compared THA and TKA patients' joint perception, satisfaction, and function via a questionnaire. Methods: One hundred elective THA (n = 50) and TKA (n = 50) patients at one institution were randomly selected and contacted between 2 and 4 years after the index surgery...

BACKGROUND: Obesity remains the strongest predictor of knee osteoarthritis (OA). Studies have reported improvement in knee pain and function post-bariatric surgery secondary to weight loss and reduced mechanical loading, yet others found increased rates of total knee arthroplasty (TKA) in that patient population. To address this controversy, our study aimed to further assess the effect of surgically induced, "rapid" weight loss on knee pain and function. METHODS: Obese patients with chronic knee pain, who were undergoing bariatric surgery, were enrolled and surveyed preoperatively and 3 months postoperatively...

BACKGROUND: The number of physically active individuals who develop knee and hip arthritis and who undergo arthroplasties of these joints ie ever increasing. It has become necessary to develop evaluation scales which address the specific issues raised by such individuals. The High Activity Arthroplasty Score is one such scales, originally developed in English. METHODS: The HAAS-I was developed by means of forward-backward translation, a final review by an expert committee and a test of the pre-final version to establish its correspondence with the original English version...

Aims Primary (or spontaneous) and secondary osteonecrosis of the knee can lead to severe joint degeneration, for which either total or unicompartmental arthroplasty may be considered. However, there are limited studies analyzing outcomes of unicompartmental knee arthroplasties (UKAs) for osteonecrosis involving an isolated compartment of the knee. The aims of this study were to analyze outcomes of UKAs for osteonecrosis with specific focus on 1) survivorship free of any revision or reoperation, 2) risk factors for failure, 3) clinical outcomes, and 4) complications...

D W Murray, R W Parkinson
Unicompartmental knee arthroplasty (UKA) has numerous advantages over total knee arthroplasty (TKA) and one disadvantage, the higher revision rate. The best way to minimize the revision rate is for surgeons to use UKA for at least 20% of their knee arthroplasties. To achieve this, they need to learn and apply the appropriate indications and techniques. This would decrease the revision rate and increase the number of UKAs which were implanted, which would save money and patients would benefit from improved outcomes over their lifetime...

Introduction: A tourniquet is used during the total knee replacement surgery to improve the visibility, to reduce the blood loss and for better cementation. Indirectly it decreases the duration of surgery and enhances the recovery of the patient. Their use however is controversial due to some side effects associated with the use of tourniquet. They may increase the risk of deep vein thrombosis and pulmonary embolism by causing venous stasis, endothelial damage and increased platelet adhesion secondary to distal limb ischemia...

BACKGROUND: There has been a debate regarding the outcomes of 2-stage revision total knee arthroplasty (TKA) when debridement, antibiotics, irrigation, and implant retention (DAIR) had been carried out previously. The purpose of this study is to evaluate the influence of prior failed DAIR (F-DAIR) on the outcomes of 2-stage revision TKA done for periprosthetic joint infection (PJI). METHODS: This is a retrospective study of a consecutive series of 184 knees that completed 2-stage revision TKA for PJI, operated by a single surgeon between January 2000 and July 2011...

Alignment of the prosthesis is one of the most significant factors that affect the long-term clinical outcome following total knee arthroplasty (TKA). There is conflicting evidence whether patient-specific instrumentation (PSI) for TKA improves the component position compared to standard instrumentation. This study aimed to compare the rotational alignment of the femoral and tibial components in TKA patients when performed with either conventional or PSI. Sixty patients with primary knee osteoarthritis were randomly divided into two groups treated surgically with TKA: one with conventional instrumentation and the other with the Visionaire PSI system (Smith and Nephew, Memphis, TN)...

Liposomal bupivacaine is a novel method for pain control after total knee arthroplasty (TKA), but recent studies showed no advantage for patients undergoing TKA compared with traditional periarticular injection (PAI). The purpose of this analysis was to compare the clinical outcomes between liposomal bupivacaine treatment and traditional PAI. We retrospectively reviewed data from 16 clinical trials in published databases from their inception to June 2017. The primary outcome was postoperative Visual Analogue Scale (VAS) score and secondary outcomes included opiate usage, narcotic consumption, range of motion, and length of stay...

Risk factors for adverse events after total knee arthroplasty (TKA) relating to malignancy have not been well studied. Thus, the purpose of this study was to conduct a retrospective case-control outcome and cost analysis after TKA in this population. Patients with a history of breast cancer (BrCa) were identified based on the International Classification of Disease 9th revision codes. An age- and sex-matched cohort was also identified of patients without a history of BrCa. Complications, length of stay, comorbidity burden, and reimbursements were tracked at 90 days...

Total Knee Arthroplasty (TKA, also known as total knee replacement) is a highly effective surgical intervention for the restoration of physical function and improving quality of life in patients with disabling knee osteoarthritis. Recent data suggest that obesity is a major risk factor in the pathogenesis and progression of knee osteoarthritis, with increases in body mass index (BMI, kg/m2 ) directly correlating with the prevalence of knee osteoarthritis. However, recent data also suggest that there are increased risks associated with TKAs when performed in patients with morbid obesity (BMI > 40 kg/m2 )...

PURPOSE: Patients with known hypersensitivity to metals often require hypoallergenic TKA implants. Coating of a standard implant is a common solution, and although in vitro tests have demonstrated reduction of polyethylene wear for these coatings, it is still unknown whether these implants have any clinical benefit. This study was initiated to investigate metal ion concentrations, knee function and patient-reported outcome (PRO) after coated and uncoated TKA. METHODS: One hundred and twenty-two (122) patients were randomized to receive a coated or a standard TKA and, after exclusions, 59 patients were included in each group...

INTRODUCTION: Unicompartmental knee arthroplasty (UKA) is a commonly used procedure for patients suffering from debilitating unicompartmental knee arthritis. For UKA recipients, robotic-assisted surgery has served as an aid in improving surgical accuracy and precision. While studies exist detailing outcomes of robotic UKA, to our knowledge, there are no studies assessing time to return to work using robotic-assisted UKA. Thus, the purpose of this study was to prospectively assess the time to return to work and to achieve the level of work activity following robotic-assisted UKA to create recommendations for patients preoperatively...
