Abstract:

BACKGROUND: Although traditional ice bag can relieve knee joint swelling post arthroscopy, hardness, poor attachment to skin, difficult fixation, and small contact area limit its application.
OBJECTIVE: To explore the effect of Cryo/Cuff system’s swelling controlling on postoperative knee arthroscopy patients.
METHODS: 140 patients undergoing postoperative knee arthroscopy were divided into Cryo/Cuff system and traditional ice bag groups with 70 patients in each group. The perimeter of knee on two centimeter of superior patellar pole, patella center, maximum musculus gastrocnemius on uninjured side were measured pre-, and 6, 12, 24, 36 and 48 hours post-operation respectively, and the value of swelling was calculated.
RESULTS AND CONCLUSION: The two groups swelling value on preoperative, two centimeter of superior patellar pole of sixth hour post- operation and maximum musculus gastrocnemius of 6, 48 hours post-operation had not statistically significant (P > 0.05). But the two groups’ swelling value on patella center of 6 hour post-operation, on two centimeter of superior patellar pole and patella center of 12, 24, 36, 48 hours post-operation, on maximum musculus gastrocnemius of 12, 24, 35 hours post-operation were significantly lower than control group (P < 0.05). Cryo/Cuff system can relieve swelling degree on postoperative knee arthroscopy patients compared to tradition ice bag.
