[Clinical observation of effectiveness in the treatment of senile knee osteoarthritis with the inactivation of myofascial trigger points---108 cases reports].

OBJECTIVE

To study clinical treatment effects of inactivating myofascial trigger points with needling and muscle stretching for the treatment of knee osteoarthritis(OA).

METHODS

Retrospective analyses were made to investigate the clinical data of pain clinic outpatient in our hospital from 2010 to 2014, and 108 patients with knee OA, including 35 males and 73 females, were treated with acupuncturing of myofascial trigger points and stretching of muscles and structure around knee. The puncturing of trigger points, and the back and forth movement of needle were required to elicit local twitch response of muscle. After acupuncture treatment, muscle stretch around the knee joint was performed by a therapist. All patients must do homework of self stretching exercise. The extent of stretching should be to gradually increased under a tolerable pain. The ROM and walking pain VAS scores were measured before and after whole therapy and were statistically analyzed during 1 year of follow up.

RESULTS

All the patients were followed up, and 95 patients had no pain after 1 year. The VAS scores were improved from preoperative severe 7.6±0.5, moderate 4.9±0.7, to mild 1.9±0.6 and painless 0.3±0.2.

CONCLUSIONS

The walking pain of knee OA might be alleviated by the acupuncture and stretch to inactivate the myofascial trigger point.
