Abstract:
Objective Toexploretheriskfactorsofchronicinjuryofmedialcollateralligament(MCL)inpatientswithosteoarthritis(OA). Methods Thestudywasconductedretrospectivelyandatotalof191patientsinourhospitalfromFebruary2017toApril2018were collected,amongthem,86casesofOApatientswithchronicinjuryofMCLastheobservationgroup,42casesofpatientswithacute MCLinjurycausedbytraumaasthecontrolgroup1,63casesofOApatientswithoutMCLinjuryascontrolgroup2.TheMRImanifestationsof kneejointsintheobservationgroupandthecontrolgroup1werecompared,thedifferencesofthedamagemechanismsbetweenthe twogroupswereanalyzed.TheMRImanifestationsandrelatedclinicaldataoftheobservationgroupandthecontrolgroup2wereanalyzed,and thefactorsthatmightcausethechronicinjuryofMCL wereidentifiedbyunivariateregressionanalysis,thenwereincludedinthe non-conditional L o g istic regression m odel for m ultivariate analysis and the risk factors and protective factors of chronic injury of MCLwerefinallyscreenedout.Results Thedifferencesinthe MRImanifestationsbetweentheobservationgroupandthecontrol group1,includingthegradingoftheMCLinjury,thegradingandthedislocationofmedialmeniscus,thedistributionofbonemarrow edema,theanteriorandposteriorcruciateligamentinjuriesandthestenosistypesofthejointspacewerestatisticallysignificant(P<0.05).The resultsrevealedthatthechronicinjuryofMCLwasrelatedtoage,sex,medialmeniscusdislocation,thegradingofmedialmeniscus, osteophyte,anteriorcruciateligamentinjury,posteriorcruciateligamentinjury,andthestenosistypeofthejointspaceusingtheunivariateanalysis (P<0.05).Theresultsrevealedthatosteophyte(OR=38.231,95%CI:6.573-222.370),medialmeniscusdislocation (OR=6.504, 95%CI:1.508-28.046),anteriorcruciateligamentinjury(OR=7.236,95%CI:1.188-44.090)wereriskfactorsforchronicinjury ofMCLinOApatientsandlateraljointspacestenosis(OR=0.014, 95%CI:0.002-0.092)andpatella-femoraljointspacestenosis (OR=0.006,95%CI:0.000-0.071)wereprotectivefactorsusing multiple L o g istic regression model.Conclusion Thepathogenicfactorsaredifferentbetweenchronicinjuryof MCLin OA patients andacuteinjuryofMCL.Osteophyte,medialmeniscusdislocation,anteriorcruciateligamentinjuryareriskfactorsforchronicinjury ofMCLinOApatients,andlateraljointspacestenosisandpatella-femoralspacestenosisareprotectivefactors.
