The cental transpatellar tendon arthroscopic approach and the standard lateral approach were compared in 200 unselected cadaver knees. A 5-mm arthroscopic dummy was used in the investigation. In 198 knees, using the transpatellar tendon approach, the dummy passed through the infrapatellar fat pad. In 7 cases with the transpatellar approach and in 22 cases with the lateral approach, we were unable to reach the medial posterior compartment of the knee joint. It was usually easier to insert the arthroscopic dummy into the posterior fossa if the knee joint was held at 35 to 40 degrees of flexion of the knee than at 90 degress of flexion. In 88 of 100 knees, the dummy could be passed from the transpatellar approach into the lateral posterior fossa and in 77 of 100 knees from the lateral approach. Patella baja was found in 16 knees (8%). Since the transpatellar tendon approach should not be used in these cases, it means that this technique cannot be used in all cases. From an anatomical point of view, the transpatellar tendon method thus does not offer any major advantages compared to the standard lateral one.
在200个未经挑选的尸体膝关节上比较了经髌腱中央关节镜入路和标准外侧入路。研究中使用了一个5毫米的关节镜模拟物。在198个膝关节中，经髌腱入路时，模拟物穿过髌下脂肪垫。在7例经髌腱入路和22例外侧入路的病例中，我们无法到达膝关节的内侧后室。如果膝关节保持在35至40度屈曲，通常比在90度屈曲时更容易将关节镜模拟物插入后窝。在100个膝关节中的88个中，模拟物可从经髌腱入路进入外侧后窝，在100个膝关节中的77个中可从外侧入路进入。16个膝关节（8%）发现髌骨低位。由于在这些病例中不应使用经髌腱入路，这意味着该技术并非在所有情况下都能使用。从解剖学角度来看，与标准外侧入路相比，经髌腱方法没有任何主要优势。
