To study the clinical application value of individualization portal for knee arthroscope meniscoplasty.

The clinical data of 100 patients who had underwent knee arthroscope meniscoplasty were retrospectively analyzed. In the patients, 50 cases were performed with routine portal (group A), and other 50 cases were performed with individualization portal (group B). The operation time, curative effect and incidence of complications were compared between 2 groups.

The operation time in group B was significantly lower than that in group A: (28.8 ± 3.1) min vs. (39.5 ± 5.4) min, and there was statistical difference (t= 12.151, P<0.01). There was no statistical difference in excellent and good rate between group A and group B: 94% (47/50) vs. 96% (48/50), χ²= 0.522, P>0.05. The incidence of meniscus and cartilage injury in group B was significantly lower than that in group A: 2% (1/50) vs. 14% (7/50), and there was statistical difference (χ²= 4.891, P<0.05). There was no statistical difference in incidence of hematoma between 2 groups (P>0.05). There was no ligament injury, infection, vascular and nerve injury, deep vein thrombosis, instrumentation damage and synovial fistula.

The individualization portal for knee arthroscope meniscoplasty is more convenient. It can shorten operation time and decrease meniscus and cartilage injury. But it has no influence on clinical effect and other complications.
