Intraoperative Arthroscopic Cold Irrigation Solution Does Not Affect Postoperative Pain and Swelling

Area of Science:

• Orthopedic Surgery
• Pain Management
• Sports Medicine

Background:

• Postoperative pain and swelling are common after arthroscopic knee surgery.
• Cold therapy is often used to manage pain and inflammation.
• The efficacy of cold irrigating solutions during arthroscopic knee surgery is not well established.

Purpose of the Study:

• To evaluate the effect of cold (4°C) versus room-temperature (18°C) irrigating saline on postoperative pain intensity.
• To assess the impact on pain-medicine consumption following arthroscopic knee surgery.
• To determine the influence on knee joint swelling in the early postoperative period.

Main Methods:

• A randomized, controlled trial involving 93 physically active patients undergoing arthroscopic knee surgery.
• Patients were blinded and assigned to either cold or room-temperature saline irrigation groups.
• Postoperative pain was measured using a visual analog scale, and swelling was assessed by girth measurements.

Main Results:

• No statistically significant or clinically meaningful differences were observed between the cold-saline and control groups.
• Pain intensity, pain-medicine consumption, and knee joint swelling showed no significant variation.
• These findings were consistent across the first four postoperative days.

Conclusions:

• Intra-articular cold saline irrigation during arthroscopic knee surgery does not appear to offer significant benefits for pain, medication use, or swelling.
• The study suggests that the use of cold irrigating solutions may not be a clinically relevant intervention for managing early postoperative outcomes in knee arthroscopy.
• Further research may explore different irrigation temperatures or durations to ascertain any potential benefits.
