“…When compared with studies on non-amputees, PT problems have previously been demonstrated with sonography. 8,10 Although structural pathologies could be easily diagnosed, similar to our study, painful complaints of the patients were not always correlated with the gray-scale sonographic findings. 8 On the other hand, color Doppler imaging was found to be better predictive of acute and symptomatic pathologies.…”

“…7 In non-amputees, patellar tendon problems due to overuse and load bearing have been reported before. [8][9][10] The role of sonography in clearly demonstrating the relevant pathological findings -even better than magnetic resonance imaging -is again well established. 10 Further, the relationship between the sonographic findings and the painful complaints of such patients has also been shown.…”

This study aimed to provide sonographic imaging of the patellar tendon (PT) -one of the main weight bearing structures for prosthetic use -in transtibial amputees. Thirteen males, who had been under follow-up for unilateral traumatic transtibial amputations, were enrolled. After physical examination of the limb, pain was evaluated by visual analogue scale and Leeds Assessment of Neuropathic Symptoms and Signs. Sonographic evaluations were performed by using a linear array probe (Aloka UST-5524-7.5 MHz) on both sides. Measurements pertaining to the contralateral limbs were taken as controls. In three subjects (23.1%), two with a silicone liner and one with a pelite liner, cortical irregularities were detected at the tibial insertion of the PT on the amputated sides. PTs were found to be thicker on the amputated sides when compared with those of the contralateral sides (p ¼ 0.03), and this increase in thickness correlated with disease duration (r ¼ 0.67, p ¼ 0.01). Overall, our preliminary results imply that after transtibial amputation, PTs of the amputated sides tend to become thicker by time. These findings need to be complemented with future studies. In this regard, sonography seems to be promising for imaging the soft tissue problems of the stump.

“…This process may lead to chronic patellar tendinosis (Jumper's knee), which affects more than 40% of sports players (6). Approximately 10% of the athlete population becomes symptomatic at one time in their life (10).…”

“…This result is contradictory to our findings of significant differences in the thickness and area of the tendon. Pfirrmann et al (6) stated that beach volleyball causes the same amount of force on each leg, which equally loads both extremities. This equal amount of loading is in contrast to volleyball or other jumping activities on hard surfaces in which one extremity bears the majority of the impetus, which suggests an effect of loading on the development of tendinosis.…”
