相反，鉗形病變與髖臼過度覆蓋有關(guān)，通常與先前存在的髖臼成熟有關(guān)11)。然而，應(yīng)該注意的是，同時(shí)伴有凸輪和鉗形病變的混合型FAI綜合征非常常見。Fromabiomechanicalpointofview,asystematicreviewwasconductedon12studiesoncam-typeFAIsyndrome(173cam-lesionsvs.177controls)andreportedthatcamlesionsreducethesagittalrangeofmotionofthehipjoint,maximumextensionangle,andabductionangleofthehipjointanddecreaseiliopsoasmusclepowerandwalkingspeed.13)VanHouckeetal.30)reportedthatincamtypeFAIsyndrome,thepeakcontactstressduring20°ofinternalrotationnearlydecreasedbyhalf(26.6–11.4MPa)afterarthroscopiccamresection.Anotherstudyusingfiniteelementmodelingonpincerlesionsshowedthatthemaximumstress-strainincreased2to3.4timesintheanterosuperioracetabularrimcomparedtothatinthecontrolgroup.31)從生物力學(xué)的角度，對12項(xiàng)關(guān)于凸輪型FAI綜合征的研究進(jìn)行了系統(tǒng)回顧(173例凸輪病變與177例對照)，并報(bào)道凸輪病變降低了髖關(guān)節(jié)矢狀面運(yùn)動(dòng)范圍、髖關(guān)節(jié)最大伸展角和外展角，并降低了髂腰肌力量和步行速度13)。VanHoucke等人報(bào)道，在凸輪型FAI綜合征中，關(guān)節(jié)鏡下凸輪切除后，20°內(nèi)旋時(shí)的峰值接觸應(yīng)力下降了近一半(26.6~11.4MPa)。另一項(xiàng)對鉗形病變進(jìn)行有限元建模的研究顯示，與對照組相比，髖臼前上緣的最大應(yīng)力應(yīng)變增加了2至3.4倍。ArecentsystematicreviewconcludedwhenarthroscopicsurgeryisperformedforFAI,flexionandinternalrotationofthehipjointoftenimproveaftersurgery,butexternalrotationanglemaynotincreasesignificantly.20)ThesestudiesprovideabiomechanicalbackgroundonhowarthroscopicsurgerycouldaidinpainandfunctionalimprovementinFAIsyndrome.最近的一項(xiàng)系統(tǒng)綜述得出結(jié)論，當(dāng)關(guān)節(jié)鏡手術(shù)治療FAI時(shí)，髖關(guān)節(jié)的屈曲和內(nèi)旋通常在手術(shù)后得到改善，但外旋角度可能不會顯著增加20)。這些研究為關(guān)節(jié)鏡手術(shù)如何幫助FAI綜合征的疼痛和功能改善提供了生物力學(xué)背景。?PatientSelectioninArthroscopicSurgeryforFAISyndromePatientselectionintreatingFAIsyndromeisespeciallyimportantinthatthecomplicationratecouldvaryamongdifferentpatientdemographics.ItiscommonlyacceptedthatobesepatientswhodevelopedarthritisarenottheidealcandidatesforsurgicalprocedurestotreatFAIsyndrome.Somestudieshaveconstructedevidenceonidealfeaturesofpatientstobetreatedwitharthroscopicsurgery.21,22)治療FAI綜合征的患者選擇尤其重要，因?yàn)椴煌颊叩牟l(fā)癥發(fā)生率可能不同。人們普遍認(rèn)為，患有關(guān)節(jié)炎的肥胖患者并不是手術(shù)治療FAI綜合征的理想人選。一些研究已經(jīng)為關(guān)節(jié)鏡手術(shù)患者的理想特征提供了證據(jù)21,22)。Kayetal.21)reportedfactorsaffectingpain,function,andqualityoflifeinpatientswhoareincludedintheFIRST(FemoroacetabularImpingementRandomisedControlledTrial)studyin2021.Theresultsofthestudyshowedthat1yearaftersurgery,theimprovementinqualityoflifewasgreaterinyoungerpatients,andtheimprovementinpainwasgreaterinpatientswithlowerbodymassindex(BMI).Nofactorsshowedanassociationwithreoperation,whichoccurredin13%.21)Kayetal.21)報(bào)道了2021年FIRST(股骨髖臼撞擊隨機(jī)對照試驗(yàn))研究中患者的疼痛、功能和生活質(zhì)量的影響因素。研究結(jié)果顯示，術(shù)后1年，年輕患者的生活質(zhì)量改善更大，體重指數(shù)(BMI)較低的患者疼痛改善更大。無因素顯示與再手術(shù)相關(guān)，再手術(shù)發(fā)生率為13%。Morerecently,Migliorinietal.22)focusedonreturntosportsafterarthroscopicsurgeryforFAIsyndromein41studies(4,063cases)andfoundthat89%wereabletoresumewithin3years.Inparticular,patientswithyoungerage,lowerbodyweight,lowerarthritisstage(T?nnisgradeI)beforesurgery,andbetterhipfunctionhadbetterpostoperativefunction.最近，Migliorini等人(22)在41項(xiàng)研究(4,063例)中關(guān)注FAI綜合征關(guān)節(jié)鏡手術(shù)后恢復(fù)運(yùn)動(dòng)，發(fā)現(xiàn)89%的患者能夠在3年內(nèi)恢復(fù)運(yùn)動(dòng)。特別是術(shù)前年齡較小、體重較輕、關(guān)節(jié)炎分期較低(T?nnisI級)、髖關(guān)節(jié)功能較好的患者，術(shù)后功能較好。?ClinicalOutcomesofArthroscopicSurgeryinFAISyndromeRecently,thereisagrowingbodyofevidencetosupporttheefficacyofarthroscopicsurgeryinFAIsyndrome.19,22,23,24,32,33)Tocomparethespecificarthroscopicproceduresintermsofefficacy,FIRSTstudywasconductedasamulticenter,blindedRCTin10institutionsinCanada,Finland,andDenmark.25)Arthroscopicosteochondroplastywascomparedwitharthroscopiclavageregardingoutcomesofpain,remainingfunctions,andqualityoflife.ThebackgroundofthisstudyreflectsthecurrentperceptionofFAIsyndrome,whichhasbecomeahugeeconomicburdenwithouttheconsensusontheeffectivenessofthesurgery.25)最近，越來越多的證據(jù)支持關(guān)節(jié)鏡手術(shù)治療FAI綜合征的療效19,22,23,24,32,33)。為了比較特定關(guān)節(jié)鏡手術(shù)的療效，F(xiàn)IRST研究在加拿大、芬蘭和丹麥的10家機(jī)構(gòu)進(jìn)行了多中心、盲法隨機(jī)對照試驗(yàn)25)。比較關(guān)節(jié)鏡下骨軟骨成形術(shù)與關(guān)節(jié)鏡下灌洗術(shù)在疼痛、剩余功能和生活質(zhì)量方面的結(jié)果。本研究的背景反映了目前對FAI綜合征的認(rèn)知，該綜合征已成為一個(gè)巨大的經(jīng)濟(jì)負(fù)擔(dān)，而對手術(shù)的有效性尚未達(dá)成共識。Almasrietal.32)soughttoreporttheclinicalcourse,especiallyintheosteochondroplastygroup,intheFIRSTtrial.Theyevaluatedpainandfunctionalscoreatbaseline,2weeks,6weeks,3months,6months,and12monthsafterthesurgery.Painvisualanalogscaleimprovedrapidlyafterthesurgeryandfunctionalscoresgraduallyrecovered,buttherewasnosignificantimprovementafter6months.32)In2022,Almasrietal.33)comparedrandomizedtolavagegroup,randomizedtoosteochondroplastygroup,thosewhodeclinedtoparticipateintheRCTbutreceivedosteochondroplasty,andthosewhodidnotfittheinclusioncriteriabutreceivedosteochondroplastyintermsofcomplicationandfunctionalscores.Painandfunctionimprovedinallpatientgroupsafter1year.ManyofthegroupsnotincludedintheRCTwerepatientswhodidnotrespondtodiagnostichipinjection,butinthisgroupofpatients,osteochondroplastyshowedalo
