Acute quadriceps tendon ruptures: A series of 50 knees with an average follow-up of more than 6 years

Introduction. Simultaneous bilateral quadriceps tendon ruptures (SBQTR) are uncommon knee injuries and most frequently occur in male patients, over 50 years of age. It can be associated with one or more predisposing risk factors like obesity, steroids use, and hyperparathyroidism. The main focus of this paper is to review SBQTR in obese patients. Case Report. We are reporting the youngest patient in the literature to date, a 24-year-old obese male patient, who presented to the emergency department complaining of bilateral knee pain and inability to walk after a fall during a basketball game. His clinical examination revealed the presence of a palpable suprapatellar gap and loss of knee extension bilaterally. Magnetic resonance imaging (MRI) confirmed that both of his quadriceps tendons were ruptured. A day after his diagnosis, the patient underwent successful operative repair followed by rehabilitation. At the two-year follow-up, the patient had full strength of both quadriceps muscles with no extension lag. Conclusion. The diagnosis of SBQTR can be challenging. Early diagnosis and treatment are associated with better functional outcome compared to delayed treatment. Physicians should have a high index of clinical suspicion in order not to miss such an injury and achieve favourable outcomes.

Background: It has been indicated that anterior cruciate ligament reconstruction (ACLR) with a quadriceps tendon (QT) graft has a higher risk of revision compared with ACLR performed with a hamstring tendon (HT) graft. Purpose/Hypothesis: To investigate whether ACLR with QT graft had a higher risk of graft failure, revision ACLR, or reoperation compared with HT graft in a high-volume center. We hypothesized that there would be no between-group differences. Study Design: Cohort study; Level of evidence, 3. Methods: This was a registry study with review of medical records. Our study cohort consisted of patients who underwent primary ACLR with either QT or HT graft performed at Copenhagen University Hospital Hvidovre between January 2015 and December 2018. The cohort was identified from the Danish Knee Ligament Reconstruction Registry and linked to the Danish National Patient Registry to identify all hospital contacts after ACLR. The outcome variables were graft failure (rerupture or >3-mm side-to-side difference in anteroposterior [AP] laxity), revision ACLR, reoperation due to cyclops lesion, reoperation due to meniscal injury, and reoperation due to any reason. AP laxity and pivot shift were assessed at 1 year. Kaplan-Meier estimates were used to evaluate the rates of events at 2 years, and comparison was performed with Cox regression analysis. Results: A total of 475 patients (252 HT, 223 QT) were included. The rate of graft failure at 2 years was 9.4% for the QT group and 11.1% for the HT group ( P = .46). For the QT and HT groups, respectively, the rate of revision ACLR was 2.3% and 1.6% ( P = .60), the rate of reoperation due to cyclops lesion was 5.0% and 2.4% ( P = .13), and the rate of reoperation due to meniscal injury was 4.3% and 7.1% ( P = .16). The rate of reoperation due to any reason was 20.5% and 23.6% ( P = .37). At 1-year follow-up, AP laxity was 1.4 mm for QT and 1.5 mm for HT ( P = .51), and the proportion of patients with a positive pivot shift was 29-30% for both groups. Conclusion: QT and HT grafts yielded similar rates of graft failure, revision ACLR, and reoperation at 2 years of follow-up after ACLR. Graft failure was found in 9% to 11% of patients. Patients with QT ACLR showed a non–statistically significant trend of higher risk for reoperation due to cyclops lesion, and those with HT showed a non–statistically significant trend of higher risk for reoperation due to meniscal injury.

Test Result

Background: The hook test is a sensitive and specific tool that has been previously described for diagnosing distal biceps tendon ruptures in an efficient, cost-effective manner. However, its application in postoperative evaluations after surgical repair of distal biceps tendon ruptures is not documented. Hypothesis/Purpose: We hypothesized that the hook test result returns to normal at some point postoperatively after distal biceps repair. This information could be used in decision making during follow-up examinations with both normal and abnormal findings. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: We retrospectively reviewed records of distal biceps repair. Between July 1, 2003, and July 1, 2016, a total of 56 patients underwent distal biceps repair and also had clear documentation of the results of the hook test during the postoperative period. Hook test results consisted of “intact,” “abnormal,” or “absent.” The timing of the return to a normal hook test result was recorded. Results: Overall, 51 of 57 (89%) repairs were documented to have the hook test result return to “intact.” The test result returned to intact by a mean of 10 weeks after surgery (range, 2 weeks to 15 months). The biceps tendon was intact according to the hook test at the 4-month follow-up in 45 of the 51 patients (88%) in whom it ultimately returned. The hook test result was abnormal in 5 repairs in 5 patients with only a short-term follow-up, ranging from 2 to 7 weeks postoperatively. One patient with an abnormal hook test result at 2 weeks postoperatively underwent revision and was confirmed to have a partial tear of the biceps insertion. His hook test result returned to intact 3 months after revision repair. Conclusion: The hook test result returns to normal in patients who undergo distal biceps repair in the primary and revision settings with adequate follow-up. The vast majority of patients have a normal hook test result by 4 months postoperatively. An abnormal hook test result at 4 months postoperatively may indicate a failed repair and should prompt further investigation.

Knee Extensor Mechanism

Quadriceps ruptures are one of the pathological conditions of the knee extensor mechanism, accounting for 3% of all tendon injuries. These injuries cause substantial disability of the extensor mechanism. Primary repair is the treatment of choice in acute presentation. In the setting of chronic conditions, the treatment becomes more challenging. Available surgical options include lengthening procedures, and reconstruction with auto graft or allografts. The traditional Scuderi and Codivilla techniques are challenging to perform in degenerative or traumatic retracted ruptures. There is no standard effective treatment in these patients, which yields the best clinical and biomechanical outcomes. An 18 - year-old male patient with quadriceps re-rupture after a primary repair was managed with allograft reconstruction using suture anchors. At six years of follow-up, the patient gained a full range of motion with excellent clinical outcomes. He returned to his previous work. In conclusion, quadriceps reconstruction using suture anchor and Achilles allograft combination is a feasible technique in neglected cases who present with quadriceps tendon re-rupture after primary surgical repair.

Prompt Diagnosis

Ruptures of the extensor mechanism of the knee are serious injuries requiring prompt diagnosis and treatment. They can be divided into soft tissue and bony causes. Soft tissue tendon injuries can be either partial or complete. Rupture of the quadriceps tendon is an uncommon injury and is more frequent in patients over the age of 40 years. Patella tendon ruptures are even rarer and are more frequent in patients under the age of 40 years. Causes can be direct or indirect. Complete ruptures of the quadriceps tendon or patella tendon benefit from early surgical management, while partial ruptures may be managed non-operatively. This article gives an overview of the presentation, assessment and management of soft tissue extensor mechanism tendon ruptures for core surgical, acute care common stem and emergency medicine trainees.

Anterior Cruciate

Background: The incidence of anterior cruciate ligament (ACL) injury in the adolescent population is increasing. The quadriceps tendon–patellar bone autograft (QPA) has been established as a reliable graft choice for ACL reconstruction in the adult population. Purpose: To investigate graft failure, ability to return to sport, patient-reported functional outcomes, joint laxity, and subsequent injury among adolescent patients >2 years after primary ACL reconstruction with the QPA. Study Design: Case series; Level of evidence, 4. Methods: Consecutive patients who underwent QPA ACL reconstruction performed by a single surgeon were identified from an existing database. Information available in the database included demographics, concomitant/subsequent injuries, surgical procedures, graft failure, return to sport, and Lachman examination collected by medical record review. Pediatric International Knee Documentation Committee (Pedi-IKDC) and Lysholm scores were collected by telephone or during a clinic visit >2 years postoperatively. Results: The final cohort included 81 of 104 consecutive adolescent patients aged 10 to 18 years (mean ± SD, 15.9 ± 1.7 years at the time of surgery) for whom follow-up information was collected at >2 years after surgery. The cumulative incidence of graft failure within the 36-month follow-up period was 1.2% (95% CI, 0.1%-11.4%). The rate of ipsilateral non-ACL injuries was similar (1.2%; 95% CI, 0.2%-7.6%). Contralateral ACL and non-ACL injuries requiring surgical intervention were documented in 9.8% (95% CI, 4.9%-19.5%). The median Pedi-IKDC score was 94 (interquartile range, 89-98). The median Lysholm score was 99.5 (interquartile range, 89.0-100.0). At 36 months after surgery, 87.9% (95% CI, 81.4%-94.9%) of individuals had returned to play. Conclusion: The quadriceps tendon–patellar autograft is a novel graft that demonstrates excellent stability and favorable patient-reported outcomes. Based on these results, the QPA is a reliable choice for primary ACL reconstruction in adolescent patients.

Tendon Ruptures

Background Although a rare event, the prevalence of major tendon rupture has increased in recent decades. Identification of risk factors is important for prevention purposes. Hypothesis Race is a risk factor for major tendon ruptures. Study Design Cohort study (prevalence); Level of evidence, 2. Methods All patients admitted for surgical management of a rupture of a major tendon at Womack Army Medical Center, Fort Bragg, North Carolina, in 1995 and 1996 were identified and evaluated for risk factors. Results The authors identified 52 major tendon ruptures 29 Achilles, 12 patellar, 7 pectoralis major, and 4 quadriceps tendon ruptures. All patients were active-duty soldiers, and 1 was a female soldier. Forty-one tendon ruptures occurred among black soldiers, 8 occurred among white soldiers, and 3 occurred among Latino soldiers. The population at risk included 93 224 exposures during the 2-year period, of which 67.1% were white, 24.5% were black, and 8.4% were self-classified as other race. The rate ratio for tendon rupture, adjusted for gender and age, was 13.3 (95% confidence interval, 6.2-28.5) between blacks and whites and 2.9 (95% confidence interval, 0.8-10.9) between Latinos and whites. Conclusion The rate of major tendon rupture was 13 times greater for black men in this study population when compared with whites. Interventions among those at a higher risk for injury should be considered.

Dash Questionnaire

Purpose of this Study: The aim of this study was to evaluate the outcomes of surgical intra-osseous fixation of the distal tendon of the ruptured biceps brachii muscle using Mitek anchors. Materials and Methods: Between 2005 and 2011, seven patients underwent unilateral distal biceps tendon repair using Mitek anchors. All patients were men aged between 36 and 47 years. Six patients were assessed by physical examination and use of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. Results: Surgery was performed within 3 to 17 days of rupture with a mean follow-up of 35 months. Of the six fully completed DASH questionnaires, three patients had a score of 0, and three patients had scores of 5.8, 10 and 10.8, respectively (10.1 is the mean score for the general population). Transient paraesthesias in the lateral antebrachial cutaneous nerve region occurred in two patients and one patient experienced a transient stiffness of the elbow due to scarring of the wound. No major complicatons have occurred. Conclusion: The use of Mitek anchors for the re-insertion of the ruptured distal biceps tendon proved to be a safe and effective technique with excellent functional results in our series.
