BACKGROUND Cruciate-retaining (CR) prostheses have been considered to produce more physiologic femoral rollback, provide better proprioception, and result in better quadriceps recovery than posterior-stabilized (PS) prostheses after total knee arthroplasty (TKA). However, there are very few studies demonstrating these benefits in an objective manner. We investigated whether CR-TKA could result ...

BACKGROUND We describe the features of modern and historical bicruciate-retaining (BCR) total knee arthroplasty (TKA) implants compared with other TKA implant designs, reviewing kinematics, proprioception, operative technique, and clinical results. METHODS We performed a review based on PubMed, Embase, CINAHL Plus, and Cochrane databases from January 1990 to April 2016 using combinations of t...

BACKGROUND The objectives of this study were to describe changes in physical activity profiles of Korean patients after TKA and to determine whether the postoperative physical activity level is influenced by patient socio-demographic factors and postoperative functional outcomes. We also sought to determine whether regular postoperative physical activity is associated with greater patient satis...

OBJECTIVES The aim of this study was to describe work status and time to return to work in patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA) and to determine which factors are associated with work status. METHODS A systematic search strategy in various databases through April 2013 was performed. All clinical studies concerning patients undergoing THA or TKA pro...

BACKGROUND To evaluate whether clinical, radiographic or MRI findings are associated with long term risk for total knee arthroplasty (TKA) in persons with knee osteoarthritis. METHODS We performed a follow-up analysis of 100 persons with knee osteoarthritis who participated in a clinical trial between 2000 and 2002. Clinical data as well as radiography and MRI of the inclusion knee were obtai...

BACKGROUND Mechanical alignment guides are designed to compensate for variations in the valgus alignment angle; however, these guides may not be adequate when a patient has coronal alignment with marked bowing deformity. Previous study demonstrates better radiographic results, but the clinical benefits are a matter of speculation. The aim of this study was to investigate whether radiographic be...

BACKGROUND Excellent results have recently been reported for both total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA), but there have been few reports about which has a better long-term outcome. The preoperative and postoperative results of TKA and UKA for osteoarthritis of the knee were thus compared. METHODS The results of 48 patients who underwent TKA and 25 patients...

PURPOSE This study is to identify preoperative cautions for revision of infected total knee arthroplasty (TKA) by understanding the differences in hematologic and hemodynamic changes between primary TKA and revision of infected TKA. MATERIALS AND METHODS The study included 40 patients in each of the two groups: one group with patients who underwent TKA and the other group with patients who un...

Background: Effective postoperative multimodal analgesia facilitates early physical rehabilitation to maximize the range of motion and prevent joint adhesions following total knee arthroplasty (TKA). Adductor canal block has been reported as a supplement protocols in patients undergoing TKA. The use ultrasound (US) guidance improved success rates blocks compared with blind approaches. Case Pres...
