Morphological and Morphometric Study on Stifle Joint of Dromedary Camel (Camelus dromedarius)

Abstract

Morphological and morphometric study was conducted on 10 freshly collected stifle joints from cadaver of adult dromedary camels (Camelus dromedarius) of local breed. In morphological study all the important anatomical structures were identified. The medial patellar ligament could not be evidenced but a medial femoropatellar ligament running between the medial epicondyle of femur and patella was found. Another strap like ligament like structure originating from medial femoral fascia and inserted on the tibial tuberosity was evidenced and it was supposed to support the patella in its normal position. The medial collateral ligament was present but its lateral counterpart could not be evidenced. The medial intercondylar tubercle of tibia was found to be somewhat elevated and larger than the lateral one. Morphometric data (length, width and thickness) of the important ligaments and anatomical structures (articular surfaces) were measured. The orientation of the medial femoro patellar ligament was at an angle of 113.8° ± 1.93° with the middle patellar ligament. There was an angle of 82.7° ± 1.77° between the meniscofemoral ligament and the ligament connecting the menisci caudally. Descriptive statistics were given as Mean ± SD (standard deviation) along with coefficient of variation to show variability of a particular dimension.
