Clinical Trial Summary

Negative pressure dressings are currently widely used in wound management. Their use is gradually being extended to surgical scars. However, studies demonstrating a clear benefit are rare, particularly in terms of postoperative discharge, the need for surgical revision due to prolonged oozing and cost. The aim of this study is to evaluate the benefit of such a device in post-operative revision prosthesis surgery (hip and knee), as well as lower limb amputations.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Discharge after 7 days	Presence of discharge at 7 days postoperatively (Day 7) Condition of the dry dressing applied on Day 7 and evaluated at least 24 hours after application (Day 8)	Day 7- Day 8
Secondary	Complications	Occurrence of post-operative complications from Day 0 to hospital discharge (or max Day 14)	Day 0 - Day 14
Secondary	Revision surgery	Occurrence of revision surgery due to persistent discharge from the day of the operation (Day 0) until discharge from hospital (or max Day 14)	Day 0 - Day 14
Secondary	Hospitalisation	Duration of hospitalisation from Day 0 to end of hospitalisation (in days)	Day 0 - Day 14
Secondary	Patient satisfaction	Reported patient satisfaction based on the responses obtained from the "Patient Evaluation Form" questionnaire completed by the patient. A numeric pain scale is included: the patient rates his pain on a scale of 0 to 10 when the last dry dressing (Opsite TM) is changed or when Prevena system (TM) is removed. Zero means "no pain," and 10 means "the worst possible pain."Participant will complete the questionnaire on Day 7.	Day 7
Secondary	Costs	Dressing repair costs (sum of the price of all dressings and materials needed for dressing repair) from Day 0 to Day 7 (in Swiss francs)	Day 0 - Day 7
Secondary	AE & ADE	Occurrence, intensity, severity, causal link with the medical device and the procedure, and characteristics of the adverse events (AEs) considered to be at least possibly related to the medical device or the procedure (= adverse events, ADEs), occurring from the day of the operation (Day 0) until discharge from hospital (or max Day 14).	Day 0 - Day 14
