“…Patellar tendon rupture after ACL reconstruction may occur during the first month after the operation, usually as a result of trauma [43], or it may occur much later, 7 months to 10 years after the procedure, as a result of a very strenuous physical activity (strong kick or high jump). In our three patients, the rupture of patellar ligament occurred after 10 months on average (7)(8)(9)(10)(11)(12) during the jump and in one patient in a car accident 60 months after ACL reconstruction. One patient received corticosteroids due to the pain in the top of the kneecap.…”

Introduction. Patellar tendon rupture is a rare injury which, if missed, leads to delayed surgical treatment and may result in the loss of the knee joint function. The aim of this study was to report our results of operative treatment of the patellar tendon rupture and point out the significance of timely diagnosis and surgical procedure. Material and Methods. This retrospective tenyear study included 20 patients, 15 males and 5 females, their mean age being 42 (20-84) years. Seven participants had an injury on the right side and 13 had an injury on the left side. Thirteen participants had the diagnosis set in the first seven days after the injury. The applied techniques were surgical suture of the tendon, bone-tendon-bone ligamentoplasty using allograft from a bone bank and bone-tendon-bone ligamentoplasty using contralateral autograft, and they were performed in 12, 5 and 3 patients, respectively. The treatment results were assessed by using the Lysholm score, measuring the range of movement in the knee joint and measuring the girth of the thigh 10 cm above the patella. Results. The follow-up period after the surgery was 4 years on average (1-10 years) and the average value of the Lysholm score was 83 (27-100). The result was found to be excellent in 11 cases, satisfactory in 5 cases and unsatisfactory in 4. A statistically significant difference (p=0.0197 p<0.05) was found in the average values of the Lysholm score between the group of patients with risk factors (71.78) and the subjects without risk factors (92.18). A statistically significant difference (p=0.008 p<0.01) was found in the Lysholm score between the patients with timely diagnosis (91.62) and cases of chronic tendon tear (67). Conclusion. Timely diagnosis and early surgical reparation are the basic imperatives in the treatment of this injury. Comorbidity and risk factors are related to a poorer postoperative Lysholm score. The method of choice is early surgical treatment.

Background: Low-cycle fatigue damage accumulating to the point of structural failure has been recently reported at the origin of the human anterior cruciate ligament under strenuous repetitive loading. If this can occur in a ligament, low-cycle fatigue damage may also occur in the connective tissue of muscle-tendon units. To this end, we reviewed what is known about how, when, and where injuries of muscle-tendon units occur throughout the body. Purpose: To systematically review injuries in the muscle-tendon-bone complex; assess the site of injury (muscle belly, musculotendinous junction [MTJ], tendon/aponeurosis, tendon/aponeurosis–bone junction, and tendon/aponeurosis avulsion), incidence, muscles and tendons involved, mechanism of injury, and main symptoms; and consider the hypothesis that injury may often be consistent with the accumulation of multiscale material fatigue damage during repetitive submaximal loading regimens. Methods: PubMed, Web of Science, Scopus, and ProQuest were searched on July 24, 2019. Quality assessment was undertaken using ARRIVE, STROBE, and CARE (Animal Research: Reporting In Vivo Experiments, Strengthening the Reporting of Observational Studies in Epidemiology, and the Case Report Statement and Checklist, respectively). Results: Overall, 131 studies met the inclusion criteria, including 799 specimens and 2,823 patients who sustained 3,246 injuries. Laboratory studies showed a preponderance of failures at the MTJ, a viscoelastic behavior of muscle-tendon units, and damage accumulation at the MTJ with repetitive loading. Observational studies showed that 35% of injuries occurred in the tendon midsubstance; 28%, at the MTJ; 18%, at the tendon-bone junction; 13%, within the muscle belly and that 6% were tendon avulsions including a bone fragment. The biceps femoris was the most injured muscle (25%), followed by the supraspinatus (12%) and the Achilles tendon (9%). The most common symptoms were hematoma and/or swelling, tenderness, edema and muscle/tendon retraction. The onset of injury was consistent with tissue fatigue at all injury sites except for tendon avulsions, where 63% of the injuries were caused by an evident trauma. Conclusion: Excluding traumatic tendon avulsions, most injuries were consistent with the hypothesis that material fatigue damage accumulated during repetitive submaximal loading regimens. If supported by data from better imaging modalities, this has implications for improving injury detection, prevention, and training regimens.
