<p>Quadriceps tendon rupture is the rarest injury with an incidence of 1.37/1,00,000/year. A patellar fracture is the most common injury associated with extensor mechanism lag, but it is rarely found to have quadriceps rupture rather than patellar tendon rupture. Normally when patella fracture occurs the force is disseminated at the bone level rather than at the muscular level. In this case, the force has disseminated at both muscle and bone leading to fracture of patella and quadriceps tendon rupture. Here we report a case of patellar fracture along with quadriceps tendon rupture.<strong></strong></p>

Abstract Background The partial articular supraspinatus tendon avulsion (PASTA) lesion repair remains a topic of debate. We have performed in situ repair of PASTA lesions using a potentially viable threading lasso fixation technique. This retrospective case series aimed to evaluate the clinical outcomes of PASTA lesion repair using threading lasso fixation. To the best of our knowledge, this is the first study to review this technique and its outcomes in terms of pain and upper extremity function. Methods Twenty-five patients with PASTA lesions who were treated with threading lasso fixation were reviewed. All patients were followed up for at least 1 year. Preoperative and follow-up data were retrospectively collected and reviewed. Clinical outcomes were assessed to evaluate the efficacy of the surgery. Results There were no postoperative complications. The average follow-up period was 25.7 (22–27) months. At the last follow-up, all patients underwent follow-up magnetic resonance imaging; only two cases showed a partially healed tendon and no case converted to full-thickness tear. Furthermore, shoulder pain decreased and mobility was recovered, with statistically significant differences in all scoring measures. Specifically, the mean visual analog scale score decreased from 5.4 ± 1.2 before surgery to 1.1 ± 0.8 at the last follow-up (t = 14.908, P < 0.01), and the mean American Shoulder and Elbow Surgeons Shoulder Assessment Form score improved significantly from 51.6 ± 6.4 to 89.3 ± 5.2 (t = 22.859, P < 0.01). Additionally, the mean University of California Los Angeles score improved from 17.8 ± 3.5 preoperatively to 32.3 ± 1.4 (t = 19.233, P < 0.01). Conclusions Arthroscopic repair using threading lasso fixation is a novel transtendinous technique for patients with partial articular supraspinatus tendon avulsion. Tendon integrity is preserved with this method, which may result in improved function. Overall, threading lasso fixation technique is an effective treatment.

Introduction. Patellar instability (PI) is a common finding in children. Current parameters describing patellofemoral joint alignment do not account for knee size. Additionally, most parameters utilize joint-crossing tibiofemoral landmarks and are prone to errors. The aim of the present study was to develop a knee size-independent parameter that is suitable for pediatric or small knees and determines the malpositioning of the distal patellar tendon insertion solely utilizing tibial landmarks. Methods. Sixty-one pediatric knees were included in the study. The tibial tubercle posterior cruciate ligament distance (TTPCL) was measured via magnetic resonance imaging (MRI). The tibial head diameter (THD) was utilized as a parameter for knee size. An index was calculated for the TTPCL and THD (TTPCL/THD). One-hundred adult knees were analyzed to correlate the data with a normalized cohort. Results. The THD was significantly lower in healthy females than in males (69.3 mm ± 0.8 mm vs. 79.1 mm ± 0.7 mm; p<0.001) and therefore was chosen to serve as a knee size parameter. However, no gender differences were found for the TTPCL/THD index in the healthy adult study cohort. The TTPCL/THD was significantly higher in adult PI patients than in the control group (0.301 ± 0.007 vs. 0.270 ± 0.007; p=0.005). This finding was repeated in the PI group when the pediatric cohort was analyzed (0.316 ± 0.008 vs. 0.288 ± 0.010; p=0.033). Conclusion. The TTPCL/THD index represents a novel knee size-independent measure describing malpositioning of the distal patellar tendon insertion determined solely by tibial landmarks.

Strong Suspicion

Distal patellar tendon avulsions are rare injuries in healthy individuals, and to date, no case affecting skeletally mature teenagers and adolescents has been reported. In the majority of cases, distal patellar tendon avulsions are associated with severe intra-articular knee lesions, signifying a high-energy trauma. We present the case of a 15.5-year-old female who was admitted to the emergency department after a knee injury. The mechanism of injury was a combination of landing after a jump off a scooter and sudden deceleration with a fixed foot. Lateral radiographs revealed a distal patellar tendon avulsion. An MRI was conducted to accurately diagnose concomitant lesions. The MRI revealed a complete tear of the ACL, and associated bone bruises on the lateral femoral condyle, and also on the posterolateral tibial plateau. A knee joint exam under general anesthesia demonstrated good stability during valgus stress testing and only a grade 1 positive Lachman test. Therefore, we decided to only reconstruct the extensor mechanism and to abstain from a primary ACL reconstruction. The presented case and review of the literature demonstrate the clinical relevance of this atypical lesion. In fact, a distal patellar tendon avulsion after physeal fusion of the proximal tibia should raise a strong suspicion of severe associated intra-articular knee lesions and requires prompt MRI investigation. However, controversy still exists regarding the management of these injuries, in particular concerning the question of whether to address both injuries in a single stage or in 2 stages.
