Aims. Day-case knee and hip replacement, in which patients are discharged on the day of surgery, has been gaining popularity during the last two decades, and particularly since the COVID-19 pandemic. This systematic review presents the evidence comparing day-case to inpatient-stay surgery. Methods. A systematic literature search was performed of MEDLINE, Embase, and grey literature databases to include all studies which compare day-case with inpatient knee and hip replacement. Meta-analyses were performed where appropriate using a random effects model. The protocol was registered prospectively (PROSPERO CRD42023392811). Results. A total of 38 studies were included, with a total of 83,888 day-case procedures. The studies were predominantly from the USA and Canada, observational, and with a high risk of bias. Day-case patients were a mean of 2.08 years younger (95% CI 1.05 to 3.12), were more likely to be male (odds ratio (OR) 1.3 (95% CI 1.19 to 1.41)), and had a lower mean BMI and American Society of Anesthesiologists grades compared with inpatients. Overall, day-case surgery was associated with significantly lower odds of readmission (OR 0.83 (95% CI 0.73 to 0.96); p = 0.009), subsequent emergency department attendance (OR 0.62 (95% CI 0.48 to 0.79); p < 0.001), and complications (OR 0.7 (95% CI 0.55 to 0.89) p = 0.004), than inpatient surgery. There were no significant differences in the rates of reoperation or mortality. The overall rate of successful same-day discharge for day-case surgery was 85% (95% CI 81 to 88). Patient-reported outcome measures and cost-effectiveness were either equal or favoured day-case. Conclusion. Within the limitations of the literature, in particular the substantial risk of selection bias, the outcomes following day-case knee and hip replacement appear not to be inferior to those following an inpatient stay. The evidence is more robust for unicompartmental knee replacement (UKR) than for total knee replacement (TKR) or

components were outside the safe zone The transverse acetabular ligament may be used to obtain the

Revision of a cemented hemiarthroplasty of the
hip may be a hazardous procedure with high rates of intra-operative complications.
Removing well-fixed cement is time consuming and risks damaging
already weak bone or perforating the femoral shaft. The cement-in-cement
method avoids removal of intact cement and has shown good results
when used for revision total hip arthroplasty (THA). The use of
this technique for the revision of a hemiarthroplasty to THA has
not been previously reported. A total of 28 consecutive hemiarthroplasties (in 28 patients)
were revised to a THA using an Exeter stem and the cement-in-cement
technique. There were four men and 24 women; their mean age was
80 years (35 to 93). Clinical and radiographic data, as well as
operative notes, were collected prospectively and no patient was
lost to follow-up. Four patients died within two years of surgery. The mean follow
up of the remainder was 70 months (25 to 124). Intra-operatively
there was one proximal perforation, one crack of the
femoral calcar and one acetabular fracture. No femoral components
have required subsequent revision for aseptic loosening or are radiologically loose. Four patients with late complications (14%) have since undergone
surgery (two for a peri-prosthetic fracture, and one each for deep
infection and recurrent dislocation) resulting in an overall major
rate of complication of 35.7%. The cement-in-cement technique provides reliable femoral fixation
in this elderly population and may reduce operating time and rates
of complication. Cite this article:
