Prosthetic joint infection (PJI) remains a devastating complication of arthroplasty. Today, most displaced femoral neck fractures in the elderly are treated with arthroplasty. We estimated the incidence of and risk factors for PJI in primary arthroplasty after femoral neck fracture. ⋯ We found a high incidence of PJI in this elderly population treated with arthroplasty after hip fracture, with possibly devastating outcome. The length of stay preoperatively increased the risk of developing PJI.

Patient-reported outcome measures (PROMs) are used by some arthroplasty registries to evaluate results after surgery, but non-response may bias the results. The aim was to identify a potential bias in the outcome scores of subgroups in a cohort of patients from the Danish Shoulder Arthroplasty Registry (DSR) and to characterize non-responders. ⋯ Non-responders did not appear to bias the overall results after shoulder replacement despite a trend of worse outcome for a subgroup of non-responders. As response rates rose markedly by the use of postal reminders, we recommend the use of reminders in arthroplasty registries using PROMs.

High age is associated with increased postoperative mortality, but the factors that predict mortality in older hip and knee replacement recipients are not known. ⋯ Postoperative mortality is low in healthy old joint replacement recipients. Comorbidities and functional limitations preoperatively are associated with higher mortality and warrant careful consideration before proceeding with joint replacement surgery.

Our unit started to use routine multimodal techniques to enhance recovery for hip and knee arthroplasty in 2008. We have previously reported earlier discharge, a trend toward a reduction in complications, and a statistically significant reduction in mortality up to 90 days after surgery. In this study, we evaluated the same cohort to determine whether survival benefits were maintained at 2 years. ⋯ This large prospective case series of unselected consecutive patients showed a reduction in mortality rate at 2 years following elective lower-limb hip and knee arthroplasty following the introduction of a multimodal enhanced recovery protocol. This survival benefit supports the routine use of an enhanced recovery program for hip and knee arthroplasty.

Instrumented and non-instrumented methods of fusion have been compared in several studies, but the results are often inconsistent and conflicting. We compared the 2-year results of 3 methods of lumbar fusion when used in degenerative disc disease (DDD), using the Swedish Spine Register (SWESPINE). ⋯ In comparison with instrumented interbody fusion, uninstrumented fusion was associated with higher levels of back pain 2 years after surgery. We found no evidence for differences in QoL between uninstrumented fusion and instrumented interbody fusion.
