Abstract Objectives Approximately 20% of knee osteoarthritis patients undergoing total arthroplasty (TKA) report chronic postoperative pain. Studies suggest that preoperative variables such as impaired descending pain control, catastrophizing, function, and neuropathic pain–like symptoms may predict 12 months after TKA, but the combined prediction value these factors has not been tested. The cu...

BACKGROUND Physical activity levels are decreased and sedentary behaviour levels are increased in patients with knee osteoarthritis (OA). However, previous studies have shown that following total knee arthroplasty (TKA), objectively measured physical activity levels do not change compared to before the surgery. Very few studies have objectively assessed sedentary behaviour following TKA. This s...

AIM The aim of this study was to evaluate whether intensity of state anxiety before operation depends on knee function. MATERIAL AND METHOD The study was conducted among 81 patients qualified to knee arthroplasty because of severe arthrosis. A knee function was evaluated with Knee Society score and Oxford questionnaires, and level of anxiety - with State-Trait Anxiety Inventory by C.D. Spielb...

BACKGROUND In a prospective cohort study, we wanted to detect thresholds distinguishing between patients with a satisfactory and an unsatisfactory outcome after total knee replacement (TKR) based on Patient-Reported Outcome Measures (PROMs), namely the Oxford Knee Score (OKS), using patient satisfaction and patient-perceived function as global transition items. METHODS Seventy-three TKR patie...

PURPOSE To report the short-term outcome of the low contact stress (LCS) patellofemoral prosthesis in 51 knees. METHODS 12 men and 37 women aged 23 to 79 (mean, 53.4) years underwent 51 consecutive LCS patellofemoral replacements. All patients had symptomatic isolated arthritis in the patellofemoral joint with well-preserved tibiofemoral compartments. All knees were evaluated pre- and post-op...

Mobile-bearing (MB) total knee replacement (TKR) was introduced to reduce the risk of aseptic loosening and wear of polyethylene inserts. However, no consistent clinical advantages of mobile- over fixed-bearing (FB) TKR have been found. In this study we evaluated whether mobile bearings have an advantage over fixed bearings with regard to revision rates and clinical outcome scores. Furthermore,...

BACKGROUND The focus in the reporting of results after total knee replacement (TKR) has changed from surgeon/radiologist-based scores to patient-reported outcome measures (PROMs). The questionnaires used in subjective outcome are often originally published in English and need to be validated in different languages. The aim of our study was to investigate the feasibility, validity, reliability, ...
