[Purpose] The purpose of this study is to provide fundamental information for efficient management of patients after a total knee replacement (TKR) through the evaluation of changes of range of motion, pain, functional level, and quality of life. [Subjects and Methods] For a total of 63 knee osteoarthritis patients, VAS, KSKS, KSFS, HSS, WOMAC scores and quality of life were evaluated for funct...

Correct positioning and alignment of components during primary total knee replacement (TKR) is widely accepted to be an important predictor of patient satisfaction and implant durability. This retrospective study reports the effect of the post-operative mechanical axis of the lower limb in the coronal plane on implant survival following primary TKR. A total of 501 TKRs in 396 patients were divi...

Many studies have shown that computer navigation in total knee arthroplasty aids the surgeon to place the prosthesis in a more accurate overall alignment. Bony resection creates the flexion and extension gaps; important in balancing the knee and implant selection in TKR. The computer plans the bone cuts but has variables that it cannot control: the surgeon, the saw blade thickness and oscillati...

Bilateral simultaneous total knee replacement (TKR) has been considered by some to be associated with increased morbidity and mortality. Our study analysed the outcome of 150 consecutive, but selected, bilateral simultaneous TKRs and compared them with that of 271 unilateral TKRs in a standardised fast-track setting. The procedures were performed between 2003 and 2009. Apart from staying longer...

Appropriate reconstruction of the bone anatomy is necessary to obtain a good functional outcome after total knee replacement (TKR) (1, 2). Restoration of the native posterior femoral offset has been described as a significant prognostic factor, mainly for completion of a good range of motion in flexion (3). The measurement of the posterior offset prior to the TKR on standard X-ray or CT-scan ma...

Total knee replacement (TKR) is an increasingly common surgery among individuals with osteoarthritis (OA). The outcomes of this surgery are positive; yet, many individuals do not fully resume their pre-TKR occupations. Literature is limited to describing the activity changes that occur but does not investigate the significance of those changes. A secondary analysis of eight purposively extracte...

Background: Patients with degenerative knee joint disease may ultimately undergo Total Knee Replacement (TKR) surgery. However, they need enough knowledge about self-care. The current study aimed at determining the knowledge score of patients undergoing TKR. Methods: The current descriptive, cross sectional study was conducted on 140 patients underwent TKR referring to selected hospitals affil...

We analysed the results of both simultaneous and staged total knee replacements (TKR) and compared them to unilateral TKR. The bilateral procedures have significantly higher rates of complications than unilateral cases, almost entirely due to thrombo-embolic problems. This does not however correspond to an increase in mortality rate. If a bilateral procedure is indicated then a simultaneous pro...

Prothrombin fragment 1+2 is excreted in urine (uF1+2) as a result of in vivo thrombin generation and can be a marker of coagulation status after an operative procedure. This study compared uF1+2 levels in patients with symptomatic and non-symptomatic venous thromboembolism (VTE) after total knee replacement (TKR) and in event-free sex- and age-matched controls. Significantly higher median uF1+2...

Between 1992 and 1994 we performed a prospective study of the effect of total knee replacement (TKR) on the health status of 119 patients over the age of 80 years who had had a primary unilateral TKR. The Nottingham Health Profile was used to assess this before and at three and 12 months after operation. We found a significant improvement in the scores for pain, emotional reaction, sleep and ph...
