Background: A potential specific problem of patellar tendon graft in ACL reconstruction is the possibility of graft-tunnel mismatch which could be more problematic with anatomic ACL reconstruction where the femoral tunnel is placed low on the lateral wall of the lateral femoral condyle. The occasional occurrence of this mismatch raises the question that whether a correlation exists between pat...

PURPOSE To assess the length of the patellar tendon in Chinese and its correlation with patient age, gender, and operated side. METHODS 109 men and 11 women aged 15 to 45 (mean, 25) years underwent arthroscopic bone-tendon-bone reconstruction for anterior cruciate ligament (ACL) insufficiency. 55 (46%) injured the left side, and 65 (54%) the right side. Each patient's age, gender, and operate...

Patellar tendon width and length are commonly used for preoperative planning for anterior cruciate ligament reconstruction (ACLR). In the study reported here, we assessed the accuracy of preoperative measurements made by palpation through the skin, and correlated these measurements with the actual dimensions of the tendons at surgery. Before making incisions in 53 patients undergoing ACLR with ...

Figure 1. Lateral knee radiograph showing patella alta. A 68-year-old male presented to the emergency department with anterior right knee pain after falling at home and directly hitting his patella on the stepladder edge while he was going upstairs. Physical examination revealed infrapatellar region painful swelling and impaired knee extension. Knee radiographs showed no fracture; however, the ...

BACKGROUND The impetus for the use of patellar straps in the treatment of patellar tendinopathy has largely been based on empirical evidence and not on any mechanistic rationale. A computational model suggests that patellar tendinopathy may be a result of high localized tendon strains that occur at smaller patella-patellar tendon angles (PPTAs). HYPOTHESIS Infrapatellar straps will decrease t...

Background: Bilateral rupture of the patellar tendon is a very rare injury, which takes place in relation to chronic systemic diseases. These injuries are known causes. Some of these causes are particular in patellar tendon rupture and another are in quadriceps tendon rupture. Case presentation: 70-year-old diabetic man with simultaneous bilateral patellar tendon disruption of proximal inser...

BACKGROUND The aim of this study was to evaluate the patellar height and degenerative changes of the knee by radiographic assessment after patellar tendon reconstruction for chronic anterior cruciate ligament deficiency. METHODS This series included 44 patients (44 knees) with an average age of 31 years and an average follow up of 58 months. The central one third of the patellar bone-tendon-b...

PURPOSE The purpose of this study was to evaluate whether a correlation exists between patient height and soft-tissue patellar tendon length. METHODS Magnetic resonance imaging (1.5 T) was performed for knee pathology on 403 patients. The patellar tendon length was measured in the midsagittal plane by a board-certified musculoskeletal radiologist. Patient height was recorded to the nearest in...
