Abstract:
This meta-analysis compared the therapeutic effect of cable pin system (CPS) with K-wire tension band (KTB) in the treatment of patella fractures among Chinese Han population.The databases of PubMed,Cochrane library,China National Knowledge Infrastructure (CNKI),Chinese WanFang and Chinese VIP were searched for studies on CPS versus KTB in the treatment of patella fractures among Chinese Han population.Literatures were screened according to the inclusion and exclusion criteria.The quality of the studies was assessed,and meta-analysis was performed using the Cochrane Collaboration's REVMAN 5.3 software.A total of 932 patients from 15 studies were included in this meta-analysis (426 fractures treated with CPS and 506 fractures treated with KTB).There were significant differences in duration of hospital stay [mean difference (MD)=-1.07;95％ confidence interval (CI):-1.71 to-0.43],fracture healing time (MD=-l.23;95％ CI:-1.68 to-0.77),flexion degree of knee joint at 6th month after operation (MD=14.82;95％ CI:10.93 to 18.71),incidence of postoperative complication [risk ratio (RR)=0.16;95％ CI:0.09 to 0.27] and excellent-good rate of B(o)stman score (RR=1.09;95％ CI:1.03 to 1.16) between the CPS group and KTB group,while no significant difference was found in operative time between the two groups (MD=-4.52;95％ CI:-11.70 to 2.67).For the treatment of patella tractures among Chinese Han population,limited evidence suggests that the CPS is more suitable than the KTB when considering the hospital stay,fracture healing time,flexion degree of knee at 6th month after operation,incidence of postoperative complication and excellent-good rate of B(o)stman joint score.Due to the limitation of high quality evidence and sample size,more large-scale randomized controlled trials are needed to validate the findings in the future.
