Clinical trials

Surgical wound complications following primary total hip arthroplasty remain a significant clinical challenge despite advances in wound care technologies. The optimal choice of dressing and frequency of dressing changes remain insufficiently investigated, particularly regarding their influence on wound healing and the wound microenvironment. This prospective, randomized, controlled clinical trial aims to evaluate the impact of dressing type and dressing change frequency on surgical wound healing in patients undergoing primary total hip arthroplasty. Ninety patients will be allocated into three treatment groups receiving either a capillary-action dressing system (VACUTEX™) or standard dressings with different dressing change intervals. The study will assess time to complete wound epithelialization, postoperative wound complications, pain intensity, wound temperature, exudate pH, length of hospital stay, and time to suture removal. In addition, the study will investigate the potential role of wound temperature and exudate pH as early indicators of impaired healing and postoperative complications.

This study investigates whether cooling the knee after total knee replacement surgery can reduce pain and improve early recovery. After surgery, patients are randomly assigned to one of three groups: cooling with a liquid cooling bandage, cooling with an ice pack, or standard postoperative care without cooling. Cooling begins 24 hours after surgery and continues for two weeks. Pain levels, use of pain medication, blood values, knee swelling, knee movement, and length of hospital stay are recorded. The goal is to determine whether postoperative knee cooling provides additional benefits compared with standard care.
