To investigate the clinical application and curative effect of isoionic microtrauma arthroscope on treatment of knee arthropathy.
From May 2003 to November 2004, 52 cases of knee joint injury were cured by using isoionic microtrauma arthroscope, including 30 cases of knee osteoarthritis, 10 cases of meniscus injury, 5 cases of knee-cap dislocation, 5 cases of laxity of anterior cruciate ligation and 2 cases of rheumatoid arthritis. In accordance with Lysholm criterion for knee joint function, the scores were 35.5 +/- 4.9 before operation.
All of these patients were followed up for 2-17 months. The scores of knee joint function was 86.4 +/- 5.3 after operation, and there was significant difference (P < 0.001).
Isoionic microtrauma arthroscope is characterized by low-temperature hemoagglutination, crimping, boiling, cutting and hemostasis, which makes knee joint arthroscope operation easier-to-do, miner histological scathe and lighter side effect; so it is favourable for functional recovery and its curative effect is satisfactory.
