[Arthroscopic surgery combined with platelet-rich plasma for meniscus injury:a Meta analysis].

OBJECTIVE

To evaluate clinical efficacy of arthroscopic with platelet-rich plasma (PRP) in treating meniscus injury.

METHODS

From January 2015 to December 2019, clinical control study on repair meniscus injury by arthroscopic with PRP between arthroscopic were searched by PubMed, Science Direct, Cochrane library, Chinese Journal Full-text Database, Wanfang and VIP database. Literature screening, data extraction and quality evaluation according to inclusion and exclusion criteria. Visual analogue scale(VAS) of knee joint and Lysholm score at 1, 6 and 12 months after opertaion between two groups were compared, and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) at 3, 6 and 12 months after opertaion between twogroups were also compared.

RESULTS

Totally 9 literatures and 329 patients with meniscal injuries were screened, include 146 patients treated by arthroscopic with PRP and 183 patients treated by arthroscopic. There were no statistical differences in VAS between two groups at 1, 6 and 12 months after opertaion. There were differences in Lysholm score at 1 and 6 months after operation between two groups [=3.85, 95% (1.25, 6.44), <0.05], [=2.88, 95% (0.13, 5.63), <0.05];while there was no difference at 12 months[=5.88, 95%(-8.72, 20.48), =0.43]. There were differneces in WOMAC score at 3 and 6 months after operation between two groups[=-8.07, 95%(-11.17, -4.89), <0.000 01], [=-7.96, 95%(-11.44, -4.48), <0.000 01];and no difference at 12 months after operation[=-6.61, 95% (-16.64, 3.41), >0.05].

CONCLUSION

Arthroscopic with PRP for repair meniscus injury has short term efficacy of knee function and delay arthritis, while has similar effect in long term clinical efficacy and relieve pain.
