Multicenter StudyWhat determines length of stay after total hip and knee arthroplasty? A nationwide study in Denmark.
The goal of this study was (1) to identify logistical and clinical areas of importance for length of stay (LOS) by identifying departments with short and long LOS and to evaluate their set-up; and (2) to evaluate patient satisfaction in relation to LOS. ⋯ Nationwide implementation of fast-track THA and TKA would result in a significant decrease in the needed number of hospital beds with similar or better outcome for the patients. Implementation of updated logistical and clinical features is expected to increase rehabilitation and reduce LOS with similar or improved patient satisfaction. These results support the implementation of fast-track total hip- and knee arthroplasty.

Randomized Controlled Trial Multicenter StudyProspective, multi-centre, randomised evaluation of the safety and efficacy of five dosing regimens of viscosupplementation with hylan G-F 20 in patients with symptomatic tibio-femoral osteoarthritis: a pilot study.
Viscosupplementation by repeated intra-articular injections of hyaluronic acid (HA) is used widely in the treatment of symptomatic knee osteoarthritis (OA). The number of injections required can limit the availability of treatment and affect patient compliance. The aim of this study was to assess different dosing regimens of hylan G-F 20, a high molecular-weight cross-linked derivative of HA, in the treatment of pain due to knee OA. ⋯ This study suggests that a single 6 mL injection of hylan G-F 20 may be as efficacious, and as well tolerated, as 3 x 2 mL one week apart. A double-blind, controlled trial is needed to confirm these data.

Multicenter Study Comparative StudyFinancing in knee arthroplasty: a benchmarking analysis.
Flat rate payment and "diagnosis related groups" (DRG) in knee arthroplasty offer incentives to save expenses. A cost-benefit analysis exactly compares all expenses to revenues. This requires patient-related assessment of treatment costs in terms of cost-unit accounting. This study compared expenses of knee arthroplasty in Austrian, German and Swiss clinics. ⋯ The proportion for personnel costs (medical, nursing, med.-tech.) of total costs was higher in Germany (41%) than Austria (26.6%) and Switzerland (39.9%). Implant costs were proportionally nearly the same in Austria (29.5%) than Germany (28%) and Switzerland (28.7%). Administration was proportionally higher in Austria (26.8%) than Germany (19.1%) and Switzerland (11.3%). To lower the costs, the expenses for personnel and implants must be reduced. Ultimately, the potential for hospitals to save costs can be found here.

Multicenter StudyPosttraumatic anterior-inferior instability of the shoulder: arthroscopic findings and clinical correlations.
The main purpose of our study was to evaluate intra-articular lesions in glenohumeral-instability with arthroscopy and correlate them with clinical findings as well as history of instability. ⋯ Thus we conclude that early surgical stabilization after posttraumatic anterior-inferior shoulder dislocation is necessary to prevent increasing damage within the shoulder joint.

Multicenter Study Clinical TrialUse of the less invasive stabilization system (LISS) in patients with distal femoral (AO33) fractures: a prospective multicenter study.
The Less Invasive Stabilization System (LISS) is an internal fixator that can be inserted percutaneously by means of a minimally invasive surgical approach. This paper presents the use of this system exclusively in patients with AO33 distal femoral fractures, a group in which fracture management is often complicated by multiple trauma and soft-tissue damage. ⋯ The LISS showed good overall results in the treatment of these difficult fractures. It is a good alternative to conventional extramedullary and intramedullary stabilizing techniques, especially in more complex fracture situations.
