Isikhundla seProsthesis: I-UKA prosthesis Overhang iya kuzisa ziphi iziphumo?

I-Unicompartmental knee arthroplasty (UKA) yenye indlela yotyando kwi-total knee arthroplasty (TKA) kunyango lwe-unicompartmental osteoarthritis. Nangona kunjalo, idatha yezinga lokungaphumeleli kwe-UKA libonisa izinga lokusinda le-7 leminyaka engama-74%, eliphantsi kakhulu kune-TKA (92%). Nangona imiba yezigulane ezayo inyusa umngcipheko wokungaphumeleli, njengezigulana eziselula kunye ne-body mass index (BMI) inokunyusa umngcipheko wokungaphumeleli kwe-UKA, iimpazamo zobuchwephesha botyando ziye zabonwa njengemiba ebalulekileyo yomngcipheko wokusilela kwangoko. Kwi-UKA, kulucelomngeni ukufezekisa ukulungelelaniswa kweprosthetic kunye ne-overhang (overhang). I-prosthesis ye-tibial kufuneka ibe nobukhulu kwaye ifakwe ngendlela yokunciphisa ukucaphuka kwezicubu ezithambileyo, kwaye i-medial tibial overhang engaphezu kwe-3 mm ibonakaliswe njengengozi enkulu yokunciphisa i-Oxford Knee Score (OKS) kunye nokwanda kwentlungu. Eyona njongo iphambili yolu phononongo yayikukuvavanya zonke iziphumo zeklinikhi kunye nemifanekiso ye-UKA. Injongo yesibini ibikukuvavanya isiphumo sokungalungi kakuhle kweprosthetic kunye nokuxhoma kakhulu kubomi bokufakelwa.

Iindlela

Olu pho nonongo lwaluyisifundo se-single-center esibandakanya izigulane zamadoda nabasetyhini abaye bafumana i-UKA ye-medial kwiziko lethu ukususela ngoJanuwari 2008 ukuya kuDisemba 2017, kwaye zonke izigulane zafumana i-UKA ngokusebenzisa iindlela eziqhelekileyo.Iikhrayitheriya zokukhutshwa kwe-UKA zibandakanya ukukhubazeka okuphakathi ukuya kwi-valgus enzima, i-patellofemoral compartment arthritis, i-posterior tibial displacement, kunye nokungazinzi. Iziphumo zeklinikhi kunye nemifanekiso zifunyenwe kwi-retrospective review yeerekhodi zeklinikhi kunye nedatha yeziko. I-Femoral coronal kunye ne-sagittal angles (i-FCA kunye ne-FSA) kunye ne-tibial coronal kunye ne-sagittal angles (TCA kunye ne-TSA) zilinganiswe kwii-radiographs kuzo zonke i-platform-platform kunye ne-movable-platform UKAs, njengoko kubonisiwe.

Isiphumo

Ukulandelwa okulinganiselweyo kwakuyiminyaka eyi-4.9 (i-0.03 ukuya kwi-10.2 iminyaka). Sichonge utyando lohlaziyo lwe-36 kunye nexesha le-3.7 iminyaka (i-0.03 ukuya kwi-8.7 iminyaka) emva kotyando kunye nezinga lokungaphumeleli elongezelelweyo le-14.2%. Ukusinda kweminyaka eyi-5 kwakuyi-88.0% (i-95% yexesha lokuzithemba [CI] = 82.0% ukuya kwi-91.0%) kunye nokusinda kweminyaka eyi-10 kwaba ngu-70.0% (95% CI = 56.0% ukuya kwi-80.0%).

Izizathu eziqhelekileyo zokuhlaziya i-prosthesis engafanelekanga / engazinzanga (31%), ukungaphumeleli komatshini (22%), ukuqhubela phambili kwe-osteoarthritis (14%), kunye neentlungu ezingabonakaliyo (8%).

Kuphela yi-11.9% ye-UKAs ephumelele konke ukulungelelaniswa okunqwenelekayo kunye nokhuseleko lokufakelwa. I-Anterior overhang ye-prosthesis yayingeyona mngcipheko omkhulu wokungaphumeleli kwe-UKA (i-10.0% izinga lokungaphumeleli, p = 0.090), kunye ne-posterior overhang ye-prosthesis (25.0%, p = 0.006) kunye ne-medial overhang ye-prosthesis (38.2%, p <0.001) yayiyimiba ebalulekileyo yomngcipheko we-UKA.

Xoxa

Kolu phononongo, sivavanye iziphumo zeklinikhi kunye nemifanekiso ye-UKA ephakathi kunye nefuthe lokulungelelaniswa kweprosthetic kunye ne-overhang. I-5 kunye ne-10 yeminyaka yokuphila yayingama-88% kunye ne-70%, ngokulandelanayo, kwaye yayingaphantsi kakhulu kune-TKA. ezona zibonakaliso zixhaphakileyo zohlaziyo yayilulungelelwaniso olubi lweprosthetic, ukusilela kumatshini, kunye nokuqhubekeka kwe-osteoarthritis. Ukulungelelaniswa okungahambi kakuhle kweprosthesis kunye ne-posterior and medial overhang zizinto ezibalulekileyo zomngcipheko wokuhlaziywa kwe-UKA.

Kuncwadi olupapashiweyo, izizathu ezibini eziphambili zokungaphumeleli kwe-UKA kukukhulula kwe-aseptic kunye ne-osteoarthritic progression, zombini ezinokusabalalisa komthwalo ongalinganiyo, ezibonisa ukuba ezi zizathu zikhankanywe ngasentla zokungaphumeleli kwe-UKA zinokuba ngumatshini kwindalo. Obu bungqina bubonisa ukuba ulungelelwaniso olubi lweprosthesis luyimbangela enokubakho yokungaphumeleli kwe-UKA kwangoko. Ke ngoko, sikholelwa ukuba kufuneka kwenziwe iinzame zokuphucula iindlela zotyando zokuphucula ulungelelwaniso lweprosthesis ye-UKA kunye nokunciphisa ukwenzeka kwe-overhang.

Iziphumo zangoku zibonisa ukuba umbutho oqinileyo phakathi kokulungelelaniswa okungalunganga kweprosthesis / overhang kunye nomngcipheko wokuhlaziya ucebisa indlela enokuthi ibekho yezinga eliphezulu lokungaphumeleli elibonwe kolu cwaningo. Ikhono logqirha lokuchaneka ngokuqhubekayo ekubekweni kweprothesis yinto ebalulekileyo ekuncedeni ukuphucula amazinga okusinda kwe-UKA.
