Bilateral Quadriceps Rupture in an Elite Weight Lifter: A Case Report and Review of Literature

Bilateral Traumatic Rupture of the Quadriceps Tendon - A Case Report

Introduction

Quadriceps tendon rupture is a traumatic injury where the quadriceps detaches from the patella, disrupting the knee's extensor mechanism. Bilateral ruptures, first documented in 1949, are rare, with an incidence of 0.17-2.5% Diagnosis involves a clinical examination, revealing a palpable defect above the patella and inability to perform a straight leg raise. Risk factors include metabolic disorders, rheumatoid arthritis, connective tissue diseases, and steroid use. In younger patients, it often results from direct trauma. Magnetic resonance imaging is the preferred diagnostic tool. While partial tears may be managed non-operatively, surgical repair is typically required for complete disruption of the extensor mechanism.

Case Report

A young man presented with an inability to walk for 1 month after a fall. He was diagnosed with bilateral quadriceps tendon rupture. Primary open repair was performed, followed by the application of bilateral long knee braces. The patient was advised delayed weight-bearing and initiated on quadriceps strengthening exercises.

Conclusion

After 12 months of follow-up, the patient showed significant improvement in function and range of motion compared to preoperative status. Primary open repair of bilateral quadriceps tendon ruptures proved to be an effective treatment, leading to satisfactory recovery and a return to good functional outcomes.

Testosterone Therapy Is Associated With Increased Odds of Quadriceps Tendon Injury

BACKGROUND

Anabolic steroid use at supraphysiologic doses has been associated with an increased risk of tendon injury. However, the musculoskeletal effects of testosterone therapy in the clinical setting are not well understood.

QUESTIONS/PURPOSES

(1) Is prescription testosterone associated with a higher odds of subsequent quadriceps muscle or tendon injury? (2) Is prescription testosterone associated with a higher odds of surgical repair of the quadriceps tendon?

METHODS

The PearlDiver Database, which contains data on Medicaid, Medicare, and commercially insured patients, allows for a large representative sample of the US population including both publicly and privately insured patients. The database was queried for all patients between 2011 and 2018 who filled a testosterone prescription. Additionally, all quadriceps injuries using ICD-9 and ICD-10 codes between 2011 and 2018 were queried. Propensity score matching based on age, sex, Charlson comorbidity index, and specific comorbidities allowed us to create matched control groups. We used the t-test and chi-square analysis to compare the unmatched and matched cohorts. A total of 151,797 patients (123,627 male patients and 28,170 female patients) with a history of filled testosterone prescriptions were included in the study after matching with the control group, which was of equal size and representation of age, male-female proportions, and comorbidities. Chi-square and logistic regression analyses were performed to compare odds of quadriceps injury and quadriceps tendon repair among the testosterone groups to that of their respective control groups by age and sex.

RESULTS

Within 1 year of filling prescriptions for testosterone, 0.06% (97 of 151,797) of patients experienced a quadriceps injury compared with less than 0.01% (18 of 151,797) of patients in the control group (OR 5.4 [95% CI 3.4 to 9.2]; p < 0.001). Within the sex-specific matched groups, filling a testosterone prescription was associated with an increase in the odds of quadriceps injury in male patients within 1 year of the prescription (OR 5.8 [95% CI 3.5 to 10.3]; p < 0.001). Additionally, patients who filled a testosterone prescription were at increased risk of having quadriceps tendon repair within a year of the injury than were patients in the matched control group (OR 4.7 [95% CI 2.0 to 13.8]; p = 0.001).

CONCLUSION

Considering these findings, it is important for physicians to counsel patients receiving testosterone replacement therapy of the substantially increased odds of quadriceps tendon injury. Future investigations into the mechanisms of influence of exogenous anabolic steroids on tendon injury remains of interest.

Popular Gym Fitness Sport: An Analysis of 1387 Recreational Athletes Regarding Prone to Pain Exercises and the Corresponding Localisations

BACKGROUND

Recreational fitness sports are popular worldwide and rank first among organised sports. This study aims to bridge a knowledge gap by examining which exercises are most prone to causing pain symptoms, as a possible precursor for injury, and analysing the body regions that are most frequently affected.

METHODS

Using an online questionnaire, 20 demographic and training-specific items and 49 sport-specific exercises were recorded. Frequent exercises as well as the incidence and distribution of pain symptoms that the athletes experienced during or in relation to their training were evaluated.

RESULTS

The study assessed common exercises and documented the frequency and distribution of pain symptoms experienced by athletes during or in relation to their training. A total of 1387 respondents were included in this study. Of these, 732 (53.1%) experienced pain during their fitness training, with 333 (24.2%) being female and 397 (22.3%) being male. The method of creating a training plan showed a significant influence (p < 0.001): athletes who devised their own plans reported pain or instability more frequently than those in the comparison groups. Guided exercises on machines resulted in the lowest frequency of pain (11.54%), while exercises with free weights were associated with the highest pain rate among respondents (19.94%). Specifically, exercises such as the back squat, deadlift, bench press, and triceps dips were identified as the exercises most commonly associated with pain. The most frequently reported pain region was the shoulder, followed by the lower back and knees.

CONCLUSION

The findings reveal a significant number of unreported pain symptoms. The disparity between rigorous training volumes and the absence of professional care frequently leads to injuries and pain. It is incumbent upon sports medicine to investigate the root causes of these complaints (pain or instability) to implement preventive measures against potential injuries.

Bilateral simultaneous quadriceps ruptures in an elite bodybuilder: A case report of treatment success

Tendon injuries in weightlifters is known to be associated with steroid use. Bilateral simultaneous quadriceps tendon rupture (BSQTR) is extremely rare with few cases reported in literature in young athletes. Unlike patellar tendon ruptures, they are more common in older age individuals. These injuries can jeopardize an athlete's career. In this paper, we report a very rare case of BSQTR in an elite bodybuilder who sustained a high mechanism trauma while squatting heavyweights. He sustained bilateral anterior cruciate ligament (ACL) injury and a left ankle fracture. All injuries were treated surgically except for the left ACL as it was asymptomatic on follow-up. The challenge in this case was to treat his injuries and to regain his baseline functional status in the shortest period of time. Following treatment, the patient had a satisfactory clinical outcome with focused rehabilitation. Despite the devastating trauma, the patient was able to progress throughout the treatment plan and has regained his baseline functional status in less than 18 months and has resumed his competitive bodybuilding career. From the available literature, this is the first case to be reported with such combined injuries that was treated and showed a satisfactory outcome in a short period of time.

Exercise Selection and Common Injuries in Fitness Centers: A Systematic Integrative Review and Practical Recommendations

Weight resistance training (RT) is an essential component of physical conditioning programs to improve the quality of life and physical fitness in different ages and populations. This integrative review aimed to analyze the scientific evidence on the relationship between exercise selection and the appearance of musculoskeletal injuries in physical fitness centers (PFC). The PubMed or Medline, EMBASE or Science Direct, Google Scholar and PEDro databases were selected to examine the available literature using a Boolean algorithm with search terms. The review process was performed using the five-stage approach for an integrative review and it was reported according to the PRISMA in Exercise, Rehabilitation, Sport Medicine and Sports Science (PERSiST) guidelines. A total of 39 peer-reviewed articles (Price index = 71.7%) met the inclusion criteria and evaluated the link between exercise selection and the incidence of injuries in exercisers who regularly attend PFC. Most injuries occur to the shoulders, elbows, vertebrae of the spine, and knees. Although the injury etiologies are multifactorial, the findings of the reviewed articles include the impacts of overuse, short post-exercise recovery periods, poor conditioning in the exercised body areas, frequent use of heavy loads, improper technique in certain exercises, and the abuse of performance- and image-enhancing drugs. Practical recommendations addressed to clinical exercise physiologists, exercise professionals, and health professionals are given in this paper. The exercise selection in RT programs requires professional supervision and adhering to proper lifting techniques and training habits that consider the anatomical and biomechanical patterns of the musculoskeletal structures, as well as genetic, pedagogical, and methodological aspects directly related to the stimulus-response process to mitigate the occurrence of RT-related injuries in PFC.
