The present invention relates to a knee trial that is coupled in advance prior to transplantation of an implant in connection with knee joint replacement so as to confirm the movability of the implant. More particularly, the present invention relates to an attachable/detachable a knee trial comprising a plate trial, an insert trial, and an adapter for easily attaching/detaching the two trials. The adapter comprises an elastic member on one side thereof such that both ends thereof pressurize the plate trial and the insert trial, respectively, thereby firmly coupling the two trials, and the same can be attached/detached simply by pressing the adapter with hand and thereby compressing the elastic member. Accordingly, during the knee joint replacement process, an implant with an appropriate size can be selected while applying various trials in a fast and accurate manner, thereby shortening the operation time and lessening the burden on the practitioner and the patient. One side of the adapter is made of plastic such that coupling is enabled without leaving scratches or the like on the plate trial. La présente invention concerne un composant d'essai de genou accouplé à l'avance avant une transplantation d'un implant en rapport avec le remplacement de l'articulation du genou de façon à confirmer la mobilité de l'implant. Plus particulièrement, la présente invention concerne un composant d'essai de genou pouvant être assemblé/séparé comprenant un composant d'essai sous forme de plaque, un composant d'essai sous forme d'insert et un adaptateur permettant d'assembler/séparer facilement les deux composants d'essai. L'adaptateur comprend un élément élastique sur l'un de ses côtés tel que ses deux extrémités mettent respectivement sous pression le composant d'essai sous forme de plaque et le composant d'essai sous forme d'insert, accouplant ainsi fermement les deux composants d'essai, ces deux derniers composants pouvant être assemblés/séparés simplement par pression de la main sur l'adaptateur et compression ainsi de l'élément élastique. Par conséquent, pendant le processus de remplacement de l'articulation du genou, il est possible de sélectionner un implant de taille appropriée en appliquant rapidement et précisément divers composants d'essai, ce qui permet de raccourcir ainsi le temps d'opération et de réduire la charge pour le praticien et pour le patient. Un côté de l'adaptateur est en plastique, ce qui permet un accouplement sans laisser de rayures, ou analogues, sur le composant d'essai sous forme de plaque. 본 발명은 슬관절 치환술에 있어 임플란트의 이식 전에 미리 결합하여 상기 임플란트의 운동성을 확인하기 위한 무릎 트라이얼에 대한 것으로, 더욱 상세하게는 플레이트 트라이얼과, 인서트 트라이얼과, 상기 두 트라이얼의 용이한 탈부착을 위한 어댑터를 포함하며, 상기 어댑터는 일측에 탄성부재를 포함하여 그 양단이 플레이트 트라이얼과 인서트 트라이얼을 각각 가압함으로써 두 트라이얼을 견고히 결합시킴과 동시에, 손으로 상기 어댑터를 눌러 탄성부재를 압축시키는 간단한 동작만으로 탈부착을 가능하게 하여, 슬관절 치환술 과정에서 여러 트라이얼을 적용해가며 적당한 사이즈의 임플란트를 선정하는 작업을 신속하고도 정확하게 진행할 수 있도록 해 시술시간을 단축 시킴으로써 시술자와 환자의 부담을 경감시킬 수 있고, 상기 어댑터의 일측은 플라스틱으로 형성하여 상기 플레이트 트라이얼에 흠집 등을 남기지 않고 결합 가능하게 하는 탈부착 가능한 무릎 트라이얼에 대한 것이다.
