Objective : In France, an increase in numbers of total hip arthroplasty (THA) and total knee arthroplasty (TKA) has been predicted for the future. In 2018, half the patients were hospitalized in orthopedic rehabilitation post-surgery. Some factors may influence the length of stay (LOS) in rehabilitation, intrinsic to the patients or environmental, pre-, per- or post-operative.

Material / Patients and Methods : Adult patients post-THA or post-TKA surgery hospitalized in our center from January 2018 to December 2020 were included (variables collected from the medical records). Pearson’s correlations or a univariable analysis of variance were first performed depending on the variable type. Variables yielding a p<0.2 were included in a multivariable model. Correlation between any variable and the LOS was validated for those with p<0.05.

Results : 96 patients post-THA and 73 patients post-TKA were identified. The median LOS was 29[21;42] days for THA and 28[24;36] days for TKA patients. Regarding THA patients: body mass index (β=0,180 CI[0,009;0,351] p=0.039), maximal passive hip flexion upon admission in rehabilitation (β=-0,188 CI[-0,376;-0,001] p=0.049), no psychiatric background (β=-0,160 CI[-0,316;-0,003] p=0.046), prior surgery for inflammatory arthritis (β=0,706 CI[0,409;1,003] p<0.0001) and the absence of a postoperative complication (β=-0,239 CI[-0,407;-0,070] p=0.006) were correlated with LOS. No factors were identified for TKA.

Discussion - Conclusion : The study highlitghted direct correlation between some factors and the LOS post-THA surgery. Crucial findings for pre-operative care: comorbidities should be optimally treated before a THA surgery. However, a longer LOS may not be deleterious for patients if hospital rehabilitation is beneficial. A prospective study is required to assess the difference between THA inpatients and outpatients.
