Displaced femoral neck fractures in healthy elderly patients have traditionally been managed with hemiarthroplasty (HA). Recent data suggest that total hip arthroplasty (THA) may be a better alternative. A systematic review of the English literature was conducted. Randomized controlled trials comparing all forms of THA with HA were included. Three authors(More)
Anterior knee pain (AKP) following total knee replacement (TKR) is both prevalent and clinically relevant. The purpose of this study was to systematically review the peer-reviewed literature, and to identify and assess the different modifiable and non-modifiable determinants that may be associated with the development of AKP in patients following primary(More)
We have reviewed the long-term results of 22 patients (23 fusions) with fractures of the os calcis, who had subtalar arthrodesis with correction of the deformity between 1975 and 1991. The mean follow-up was nine years (5 to 20). All patients were evaluated according to a modified foot score. A radiological assessment was used in which linear and angular(More)
BACKGROUND There is a current trend in orthopaedic practice to treat nondisplaced or minimally displaced fractures with early open reduction and internal fixation instead of cast immobilization. This trend is not evidence-based. In this systematic review and meta-analysis, we pool data from trials comparing surgical and conservative treatment for acute(More)
BACKGROUND Systematic reviews published on the same topic during a similar period of time (i.e., overlapping reviews) on anterior cruciate ligament reconstruction complicate the choice between bone-patellar tendon-bone or hamstring tendon autograft. We aimed to evaluate reasons for differences among the overlapping systematic reviews and to assess the(More)
The management of the subcapital fracture of the fifth metacarpal bone, the boxer's fracture, is still a matter of debate. Besides the question of which rate of angulation is acceptable before a reduction becomes necessary, recommendations for further treatment of this fracture vary as well. Therefore, the aim of our study was to compare randomly and(More)
BACKGROUND AND PURPOSE The aim of short-stem total hip arthroplasty is to preserve proximal bone stock for future revisions, to improve biomechanical reconstruction, and to make minimally invasive approaches easier. It is therefore being increasingly considered to be a sound alternative to conventional total hip arthroplasty, especially for young and active(More)
High quality instruments are useful tools for clinical and research purposes. To determine whether an instrument has high quality, measurement properties such as reliability and validity need to be assessed, using standardised criteria. This paper discusses these quality domains and measurement properties using the standardised criteria that were recently(More)
OBJECTIVE This systematic review aims to summarise all the available evidence related to the association between pre-operative patient expectations (outcome expectations, process expectations and self efficacy expectations) and 5 different treatment outcomes (overall improvement, pain, function, stiffness and satisfaction) in patients with total knee or(More)
BACKGROUND Recommendations for cast immobilization of acute scaphoid fractures vary substantially. We reviewed data from randomized controlled trials comparing nonoperative treatment methods for acute scaphoid fractures to determine the best available evidence. METHODS A systematic search of the medical literature from 1966 to 2010 was performed. Two(More)
