Any modality that alters joint homeostasis could have a potential negative effect on cartilage. During arthroscopic knee surgery, the temperature in the knee joint decreases significantly. The use of cryotherapy after this surgical procedure could maintain or increase these temperature variations. This prospective, randomized study evaluated the change in intra-articular knee temperature with the use of the Cryo/Cuff (Aircast Inc, Summit, New Jersey) in 30 patients after arthroscopic knee surgery. In 15 patients, a Cryo/Cuff with an automatic pump was applied immediately after surgery (group 1), and in the remaining 15 patients, only a wound dressing was applied (group 2). The mean intra-articular temperature at the beginning of the procedure was 34.8+/-1 degrees C for both groups. At the end of surgery, the temperature was 26.8+/-2.2 degrees C for group 1 and 27.5+/-2.2 degrees C for group 2. One hour after the end of the procedure, the mean temperature was 34+/-1.6 degrees for group 1 and 34.8+/-1.7 degrees C for group 2. These differences were not statistically significant. These results demonstrated that the use of the Cryo/Cuff does not alter temperature recovery in the knee, thereby excluding potential damage to the articular cartilage.
任何改变关节内环境稳定的方式都可能对软骨产生潜在的负面影响。在膝关节镜手术期间，膝关节内的温度会显著下降。在此手术过程后使用冷冻疗法可能会维持或加剧这些温度变化。这项前瞻性随机研究评估了30例膝关节镜手术后使用Cryo/Cuff（Aircast公司，新泽西州萨米特）时膝关节腔内温度的变化。15例患者在手术后立即应用带有自动泵的Cryo/Cuff（第1组），其余15例患者仅进行伤口包扎（第2组）。两组在手术开始时关节腔内的平均温度均为34.8±1℃。手术结束时，第1组的温度为26.8±2.2℃，第2组为27.5±2.2℃。手术结束1小时后，第1组的平均温度为34±1.6℃，第2组为34.8±1.7℃。这些差异无统计学意义。这些结果表明，使用Cryo/Cuff不会改变膝关节的温度恢复，从而排除了对关节软骨的潜在损害。
