A Mono-centre, Post CE-mark, Prospective-randomized Clinical Trial to Evaluate the Performance of a Flexible Self-adherent Absorbent Dressing Coated With a Soft Silicone Layer After Hip or Knee Arthroplasty or Primary Spine Surgery in Comparison to a Standard Wound Dressing (Cosmopor E®Steril, Fa. Hartmann) (NCT02771015)

Male or female subjects, 18 years and above, undergoing hip, knee or spinal surgery with an expected hospital stay for 4 days or more will be included in the trial. Individual trial duration will be for 7 days (follow-up). Two hundred subjects will be included in the trial, i.e. 100 subjects per arm. The treatment arm (either new or standard wound dressing) will be assigned by randomization stratified by type of surgery (i.e. hip, knee or spine).

      - Dressing change (application and removal)

      - Drainage (drainage used, application of the drainage)

      - Compression Medication (pain medication and systematic antibiotic treatment)

      - Photo (photo before and after dressing removal and if signs of infection)

      - Investigator/nurse evaluation (ease of application of the dressing, size of the dressing, shape of the dressing, visibility beneath the dressing, notice any pain at dressing change, ease of removal of the dressing, overall experience)

      - Patient evaluation (the patient's overall experience of the dressing, comfort when wearing the dressing).

      - Contentious pain - measured by Visual Analog Scale (VAS) Prüfplan: CLOSE 2.0F 28.10.2013 5(40)
