The adductor tubercle is a dependable milestone for investigating the level of the femorotibial joint line. The average edge of the popliteal surface closures beneath at the summit of the average condyle, in a little tubercle, the adductor tubercle, which bears inclusion to the ligament of the Adductor Magnus.
Reason of adductor tubercle
The proportion of femoral width and separation from average epicondyle to joint line helps gauge the femoral joint line position from femoral width. The roughly spiral position of the average epicondyle on femoral condyle circles is most likely in charge of this relationship, The adductor tubercle around untruths oppositely inverse to the joint line on the condylar circle. At that point, a straight relationship could likewise exist between the femoral width and separation of adductor tubercle to joint line and is the motivation behind the current investigation.
Femoral width, alongside the separation to the joint line from the average epicondyle, the adductor tubercle and fibular shaft, was estimated on 110 standard Antero-back knee radiographs. The relationship between’s femoral width and these estimations were assessed. The individual proportion of FW with adductor tubercle joint line, average epicondyle joint line and fibula joint line was ascertained utilizing straight relapse investigation. Intra-onlooker and between spectator unwavering quality was evaluated.

The direct connection was found between femoral width and separation of adductor tubercle to a joint line (r = 0.83). It was more solid than the relationship between’s femoral width and separation from average epicondyle to the joint line (r = 0.52). Between eyewitness, repeatability was better for separation from adductor tubercle to joint line than for separation from average epicondyle to the joint line.
We reason that adductor tubercle can be utilized as a morphologic milestone to decide the knee joint line position, on the grounds that a straight relationship between’s femoral width and separation from the adductor tubercle to the joint line was found.
