Aims

To identify variables independently associated with same-day discharge (SDD) of patients following revision total knee arthroplasty (rTKA) and to develop machine learning algorithms to predict suitable candidates for outpatient rTKA.

Methods

Data were obtained from the American College of Surgeons National Quality Improvement Programme (ACS-NSQIP) database from the years 2018 to 2020. Patients with elective, unilateral rTKA procedures and a total hospital length of stay between zero and four days were included. Demographic, preoperative, and intraoperative variables were analyzed. A multivariable logistic regression (MLR) model and various machine learning techniques were compared using area under the curve (AUC), calibration, and decision curve analysis. Important and significant variables were identified from the models.

Aims

Return to sport following undergoing total (TKA) and unicompartmental knee arthroplasty (UKA) has been researched with meta-analyses and systematic reviews of varying quality. The aim of this study is to create an umbrella review to consolidate the data into consensus guidelines for returning to sports following TKA and UKA.

Methods

Systematic reviews and meta-analyses written between 2010 and 2020 were systematically searched. Studies were independently screened by two reviewers and methodology quality was assessed. Variables for analysis included objective classification of which sports are safe to participate in postoperatively, time to return to sport, prognostic indicators of returning, and reasons patients do not.

Objectives

The objective of this study was to perform a meta-analysis of all randomised controlled trials (RCTs) comparing surgical and non-surgical management of fractures of the proximal humerus, and to determine whether further analyses based on complexity of fracture, or the type of surgical intervention, produced disparate findings on patient outcomes.

Methods

A systematic review of the literature was performed identifying all RCTs that compared surgical and non-surgical management of fractures of the proximal humerus. Meta-analysis of clinical outcomes was performed where possible. Subgroup analysis based on the type of fracture, and a sensitivity analysis based on the type of surgical intervention, were also performed.

Purpose: To determine if early MRI diagnosis in the acutely injured knee affects management, use of resources and patient satisfaction compared to conventional management with physiotherapy.

Methods: Patients referred to fracture clinic with acute knee injury in whom a specific clinical diagnosis could not be made were randomised to one of two groups. The MRI group had a scan within 2 weeks and were then reassessed in clinic with management according to the results. The control group received physiotherapy and then reassessed. Patients were assessed in clinic on presentation, at 2 weeks and then by a telephone questionnaire at 3 months. Electronic medical records were also reviewed.

Results: 48 patients were recruited in total: 23 in the MRI group (78.2% male, 21.8% female) and 25 in the control group (68% male, 32% female). The mean age was similar in the two groups (29 years (range 18–61) vs. 30 years (18–50)). The MRI group had significantly less physiotherapy appointments (5 ± 3.42 vs. 2.52 ±1.93, p=0.003) on average until definitive treatment but not outpatient appointments (2.72 ± 1.1 vs. 2.43 ±0.66, p=0.27). Median time to surgery was less in the MRI group (138 (31–199) vs.180 days (33–826) vs.) but not statistically significant (p=0.19). A similar number of patients returned to work in both groups (82.6% vs. 76%) but the MRI group had less time off work (15.82 ±22.26 vs. 20.56 ±25.38 days, p=0.48) and statistically better satisfaction scores (2 ±2.68 vs. 3.5 ±2.75, p=0.048) than the control group.

Conclusion: We have shown that early MRI in acute knee injury can provide early diagnosis of internal derangement and therefore allow targeted treatment. These patients had significantly less physiotherapy appointments and less time off work which may offset the cost of the MRI. Moreover these patients were significantly more satisfied with the service.
