Socio-professional Categories and Return to Work After Hip or Knee Replacement Surgery

A significant proportion of patients (15 to 45%) who have benefited from a total hip or knee replacement surgery (THKA), are put on sick leave (SL). This SL allows these patients who had a professional activity at the time of the intervention (age \<65 years) to enhance the healing, improve the quality of life and ensure a functional return to work. The number of patients returning to work and the time taken to return to work after the intervention are d depending on the intervention (hip or knee) and are linked to socio-demographic factors, to the patient's general condition (comorbidity, presence of other arthritis joints...) and the type of professional activity.

Studies evaluating the impact of the type of professional activity on the return to work after THKA are nonexistent in France, rare in the literature, mostly retrospective and methodologically weak. In addition, the individual and socioeconomic impact of the cessation of work after an THKA, the absence of national data assessing the predictive nature of socio-professional categories on the return to work using a multivariate analysis motivated us to set up this study.

The data usually collected in the medical file will be collected as part of the preoperative and 3 months postoperative study. As part of this study, a phone call will be made to contact patients who have had a prolonged SL

The data collected are as follows:

During hospitalization Socio-demographic data: sex, age, title of the profession, the joint concerned, family situation, place of life, postoperative availability of a caregiver or home help if necessary.

Clinical data: Comorbidities, weight, height, date of the arthroplasty, per and or postoperative complications of the arthroplasty, date of prescribed work stoppage

3 months postoperative: medical consultation Date of the 3-month consultation, date and method of resumption of work, if applicable, otherwise the duration of the extension of the duration of the SL, the doctor prescribing the extension and the causal link of this extension to the arthroplasty

4 months postoperative: telephone call This phone call will relate to patients whose work stoppage has been extended. Will be collected, the date and the mode of resumption of work, if not the cause of not resumed.

For patients whose prolongation of SL has been prescribed by the attending physician, the doctor of the rehabilitation center (knee prostheses) or by the occupational physician, the latter will be contacted by telephone to collect the reason for prolongation of the TA.
