Total knee arthroplasty has revolutionized the care of patients with end-stage knee arthritis. Expectation is defined as patient`s anticipation of events like pain, capability of performing activities and recovery following the surgery [1]. Expectation do variably influence self-rated outcome i.e. satisfaction after surgery.[2] The outcome of total knee arthroplasty should be assessed not only ...

BACKGROUND The aim of this study was to evaluate causes of unstable total knee arthroplasty and results of revision surgery. METHODS We retrospectively reviewed 24 knees that underwent a revision arthroplasty for unstable total knee arthroplasty. The average follow-up period was 33.8 months. We classified the instability and analyzed the treatment results according to its cause. Stress radiog...

The purposes of this study were to determine the probabilities of subsequent lower extremity arthroplasty after index knee arthroplasty for osteoarthritis and to evaluate the demographic as well as radiographic factors that may predict progression to arthroplasty in the contralateral knee. Between 1984 and 1994, 646 patients, aged 40 to 75 years, with a primary cruciate-retaining knee were iden...

OBJECTIVE To investigate the role of early initiation of rehabilitation on length of stay (LOS) and cost following total hip arthroplasty, total knee arthroplasty, or unicompartmental knee arthroplasty. DATA SOURCES Electronic databases PubMed, CINAHL, Pedro, Embase, AMED, and the Cochrane Library were searched in July 2016. Five additional trials were identified through reference list scanni...

OBJECTIVE To define the anthropometric profile of the knee in a Brazilian population with gonarthrosis using intraoperative measurements; and to evaluate the compatibility of three implants available for total knee arthroplasty. METHODS Morphometric data were collected prospectively from 117 subjects with gonarthrosis. Six dimensions in the distal femur and two in the proximal tibia were docu...

Total knee arthroplasty has been an effective treatment for advanced degenerative joint disease. Traditional knee designs and surgical approaches have resulted in consistently high performance, but some patients may remain dissatisfied after their surgery. Several surgical innovations, including accelerometer-based navigation, patient-specific instrumentation, and robotic-assisted total knee ar...

Metallic debris from metal-on-metal bearings is a recognized mode of failure that may lead to implant loosening and periprosthetic soft tissue reactions. The sequelae of metallosis have been most commonly reported with respect to total hip arthroplasty. The authors report a rare case of metallosis following a hybrid metal-on-polyethylene total knee arthroplasty that used a porous tantalum tibia...

BACKGROUND Thirty thousand knee replacements are performed annually in the UK. There is uncertainty as to the best surgical approach to the knee joint for knee arthroplasty. We planned a randomised controlled trial to compare a standard medial parapatellar arthrotomy with sub-vastus arthrotomy for patients undergoing primary total knee arthroplasty in terms of short and long term knee function....

OBJECTIVE Severe bone loss associated with failed revision total knee arthroplasty is a challenging scenario. The pedicled fibular flap is a method to obtain vascularized bone for use in knee arthrodesis after failure of a total knee arthroplasty, with substantial loss of bone. METHODS We report 2 successful knee arthrodeses using this method in patients with infected, failed multiply revised...
