Testosterone replacement therapy is associated with increased odds of Achilles tendon injury and subsequent surgery: a matched retrospective analysis. J Foot Ankle Res 2023; 16:76. [PMID: 37950322 PMCID: PMC10638827 DOI: 10.1186/s13047-023-00678-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 10/27/2023] [Indexed: 11/12/2023] Open
Abstract
BACKGROUND Prescription of testosterone replacement therapy (TRT) has increased in the United States in recent years, and though anabolic steroids have been associated with tendon rupture, there is a paucity of literature evaluating the risk of Achilles tendon injury with TRT. This study aims to evaluate the associative relationship between consistent TRT, Achilles tendon injury, and subsequent surgery. METHODS This is a one-to-one matched retrospective cohort study utilizing the PearlDiver database. Records were queried for patients aged 35-75 who were prescribed at least 3 consecutive months of TRT between January 1, 2010 and December 31, 2019. Achilles tendon injuries and subsequent surgeries were identified using ICD-9, ICD-10, and CPT billing codes. Multivariable logistic regression was used to compare odds of Achilles tendon injury, Achilles tendon surgery, and revision surgery, with a p-value < 0.05 representing statistical significance. RESULTS A sample of 423,278 patients who filled a TRT prescription for a minimum of 3 consecutive months was analyzed. The 2-year incidence of Achilles tendon injury was 377.8 (95% CI, 364.8-391.0) per 100,000 person-years in the TRT cohort, compared to 245.8 (95% CI, 235.4-256.6) in the control (p < 0.001). The adjusted analysis demonstrated TRT to be associated with a significantly increased likelihood of being diagnosed with Achilles tendon injury (aOR = 1.24, 95% CI, 1.15-1.33, p < 0.001). Of those diagnosed with Achilles tendon injury, 287/3,198 (9.0%) of the TRT cohort subsequently underwent surgery for their injury, compared to 134/2,081 (6.4%) in the control cohort (aOR = 1.54, 95% CI, 1.19-1.99, p < 0.001). CONCLUSIONS There is a significant association between Achilles tendon injury and prescription TRT, with a concomitantly increased rate of undergoing surgical management. These results provide insight into the risk profile of TRT and further research into the science of tendon pathology in the setting of TRT is an area of continued interest.

Abstract
Bilateral spontaneous quadriceps tendon rupture is a rare condition characterized by the simultaneous tear of the fibrous tissue connecting the quadriceps muscle to the patella bone. Prompt diagnosis is crucial for appropriate treatment and optimal outcomes. We present a case of a 70-year-old male with bilateral knee pain and an inability to walk, resulting from a trivial fall. Despite initial misdiagnosis, a thorough evaluation, including physical examination and imaging, revealed bilateral quadriceps tendon rupture. Surgical repair was performed, followed by a comprehensive rehabilitation program. At the four-month follow-up, the patient showed significant improvement in pain and function. This article provides a comprehensive review of the existing literature on bilateral quadriceps tendon rupture, emphasizing the challenges in the diagnosis and management of this rare condition. Early diagnosis, prompt surgical intervention, and a tailored rehabilitation program are crucial for successful outcomes.

Clin Orthop Relat Res 2023; 482:00003086-990000000-01253. [PMID: 37404114 PMCID: PMC10723858 DOI: 10.1097/corr.0000000000002744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 04/24/2023] [Accepted: 05/30/2023] [Indexed: 07/06/2023]
Abstract
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. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Triceps tendon avulsion is a rare but debilitating condition and the least frequent of all tendon injuries, but it is receiving increasing attention in the literature. The most common mechanism of injury is resisted extension, which is typically seen in a fall onto an extended hand. Such injuries are easily overlooked and should be considered a differential diagnosis in all patients who describe pain and swelling at the posterior aspect of the elbow following a traumatic event. Non-operative management is the general principle for partial rupture as opposed to a variety of surgical treatments for a complete avulsion. The goal of this meta-analysis is to analyse the current literature on triceps avulsion and provide a detailed overview of the occurrence, diagnosis, treatment options and outcomes, comparison of various repair techniques, and consequences of this injury.

Abstract
ResumoO tecido muscular esquelético possui a maior massa do corpo humano, correspondendo a 45% do peso total. As lesões musculares podem ser causadas por contusões, estiramentos ou lacerações. A atual classificação separa as lesões entre leves, moderadas e graves. Os sinais e sintomas das lesões grau I são edema e desconforto; grau II, perda de função, gap e equimose eventual; grau III, rotura completa, dor intensa e hematoma extenso. O diagnóstico pode ser confirmado por ultrassom (dinâmico e barato, porém examinador-dependente); e ressonância magnética (RM) (maior definição anatômica). A fase inicial do tratamento se resume à proteção, ao repouso, ao uso otimizado do membro afetado e crioterapia. Anti-inflamatórios não hormonais (AINHs), ultrassom terapêutico, fortalecimento e alongamento após a fase inicial e amplitudes de movimento sem dor são utilizados no tratamento clínico. Já o cirúrgico possui indicações precisas: drenagem do hematoma, reinserção e reforço musculotendíneos.

Abstract
Background and Objectives: Androgens play a significant role in the development of male reproductive organs. The clinical use of synthetic testosterone derivatives, such as nandrolone, is focused on maximizing the anabolic effects and minimizing the androgenic ones. Class II anabolic androgenic steroids (AAS), including nandrolone, are rapidly becoming a widespread group of drugs used both clinically and illicitly. The illicit use of AAS is diffused among adolescent and bodybuilders because of their anabolic proprieties and their capacity to increase tolerance to exercise. This systematic review aims to focus on side effects related to illicit AAS abuse, evaluating the scientific literature in order to underline the most frequent side effects on AAS abusers’ bodies. Materials and Methods: A systematic review of the scientific literature was performed using the PubMed database and the keywords “nandrolone decanoate”. The inclusion criteria for articles or abstracts were English language and the presence of the following words: “abuse” or “adverse effects”. After applying the exclusion and inclusion criteria, from a total of 766 articles, only 148 were considered eligible for the study. Results: The most reported adverse effects (found in more than 5% of the studies) were endocrine effects (18 studies, 42%), such as virilization, gynecomastia, hormonal disorders, dyslipidemia, genital alterations, and infertility; cardiovascular dysfunctions (six studies, 14%) such as vascular damage, coagulation disorders, and arteriosus hypertension; skin disorders (five studies, 12%) such as pricking, acne, and skin spots; psychiatric and mood disorders (four studies, 9%) such as aggressiveness, sleep disorders and anxiety; musculoskeletal disorders (two studies, 5%), excretory disorders (two studies, 5%), and gastrointestinal disorders (two studies, 5%). Conclusions: Based on the result of our study, the most common adverse effects secondary to the abuse of nandrolone decanoate (ND) involve the endocrine, cardiovascular, skin, and psychiatric systems. These data could prove useful to healthcare professionals in both sports and clinical settings.

Abstract
Quadriceps tendon rupture is an uncommon injury and mostly occurs among middle aged individuals that are involved in sports such as running or jumping. Spontaneous bilateral quadriceps tendon rupture is a rarer injury, however, can be debilitating. Patients with such injuries usually present with history of minor trauma, swelling and inability to actively extend the knee. Its occurrence secondary to minor trauma is mostly associated with chronic diseases and long-term use of certain medications. Occurrence of simultaneous bilateral quadriceps tendon rupture in the absence of trauma in a healthy patient with no known medical condition is yet to be reported and therefore requires a high index of suspicion for early diagnosis and effective management to avoid complications. The aim of this case report is to create awareness of the spontaneous occurrence of this injury in the absence of the reported risk factors. We report the unusual case of a 60-year old healthy man who presented with a spontaneous simultaneous bilateral quadriceps' tendon rupture in the absence of trauma and no medical risk factors. We report the unusual case of a 60-year old healthy man who presented with a spontaneous simultaneous bilateral quadriceps tendon rupture in the absence of trauma and no medical risk factors. Consent was taken from him to be used as a case report being a rare case. The man had full recovery after surgery and physiotherapy and was discharged home. Spontaneous bilateral quadriceps tendon rupture is a rare occurrence. The index case report is important as there was no history of trauma and it was bilateral.

Abstract
Simultaneous bilateral extensor mechanism disruption (BEMD) is a rare condition, for which the relationship between comorbid conditions, complications, and clinical outcomes has not been well defined. We hypothesized that patients with BEMD would have more comorbidities, more repair failures, and worse clinical outcomes compared with patients with unilateral extensor mechanism disruption (UEMD). We performed a retrospective review of all adult patients seen at our institution for either a quadriceps or patellar tendon rupture between 2012 and 2017. Statistical analysis was conducted using Student's t-tests and Fisher's exact tests. Significance was defined as p < 0.05. Fourteen patients with BEMD and 221 patients with UEMD were included for comparison. The average length of follow-up was 268 days. Patients with BEMD had higher body mass indexes and higher American Society of Anesthesiologists scores than patients with UEMD. They also had worse Patient-Reported Outcomes Measurement Information System physical function scores, nearly four times the length of stay, and three times the rate of repair failures as patients with UEMD. At final follow-up, all 14 patients in the BEMD group were ambulatory and 9 of the 10 patients who were working prior to injury had returned to work. Simultaneous BEMD are rare injuries, occurring in only 6% of the current series. When treating these patients, orthopaedic surgeons should have a heightened awareness that they have more comorbidities, more failures, and worse functional outcomes than their unilateral counterparts.

Abstract
Simultaneous bilateral quadriceps tendon ruptures (QTR) are rare injuries in sportspersons; weightlifting, involving sudden eccentric contraction of the bilateral quadriceps, has the potential to cause this injury. We present a case of an elite weightlifter with bilateral quadriceps tear occurring during the "jerk" part of clean and jerk phase of weightlifting; single stage bilateral end to end repair was done, followed by 3 weeks of cast immobilisation. He then underwent a supervised rehabilitation protocol, leading to graduated strengthening of the muscles. He went back to competitive sport after 2 years and participated in a national championship after 5 years. Detailed questioning revealed a history of anabolic steroid use in the early phase of his career; a literature review showed only seven cases of this injury pattern in weightlifting/bodybuilding sports, and five of these seven had a definitive history of anabolic steroid use. Bilateral QTR may be a pointer to predisposing factors like use of steroids, which should be diligently identified. Good outcomes are possible after early surgical repair and rehabilitation, with high rates of return to sports.

Abstract
BACKGROUND A growing body of evidence suggests that anabolic androgenic steroids (AAS) are used globally by a diverse population with varying motivations. Evidence has increased greatly in recent years to support understanding of this form of substance use and the associated health harms, but there remains little evidence regarding interventions to support cessation and treat the consequences of use. In this scoping review, we identify and describe what is known about interventions that aim to support and achieve cessation of AAS, and treat and prevent associated health problems. METHODS A comprehensive search strategy was developed in four bibliographic databases, supported by an iterative citation searching process to identify eligible studies. Studies of any psychological or medical treatment interventions delivered in response to non-prescribed use of AAS or an associated harm in any setting were eligible. RESULTS In total, 109 eligible studies were identified, which included case reports representing a diverse range of disciplines and sources. Studies predominantly focussed on treatments for harms associated with AAS use, with scant evidence on interventions to support cessation of AAS use or responding to dependence. The types of conditions requiring treatment included psychiatric, neuroendocrine, hepatic, kidney, cardiovascular, musculoskeletal and infectious. There was limited evidence of engagement with users or delivery of psychosocial interventions as part of treatment for any condition, and of harm reduction interventions initiated alongside, or following, treatment. Findings were limited throughout by the case report study designs and limited information was provided. CONCLUSION This scoping review indicates that while a range of case reports describe treatments provided to AAS users, there is scarce evidence on treating dependence, managing withdrawal, or initiating behaviour change in users in any settings. Evidence is urgently required to support the development of effective services for users and of evidence-based guidance and interventions to respond to users in a range of healthcare settings. More consistent reporting in articles of whether engagement or assessment relating to AAS was initiated, and publication within broader health- or drug-related journals, will support development of the evidence base.

Abstract
Anabolic androgenic steroids (commonly known as anabolic steroids) are synthetic derivatives of the hormone testosterone. They are being increasingly used by professional and recreational athletes to enhance performance, and by men and women to improve physical appearance. This article discusses the characteristics of such steroid ‘misusers’ and the techniques of use. It highlights the psychiatric complications associated with these steroids, including increased risk of aggression, personality disorders, psychosis and mood disorders, particularly manic symptoms. Medical complications of steroid use are common and frequently reversible. Use is associated with an increased risk of injury, cardiovascular events, gastrointestinal complications, virilisation in women, and gynaecomastia and testicular atrophy in men. Whether addiction to these steroids can occur is debatable, but there is evidence for dependence and a withdrawal syndrome. Steroid use may be a ‘gateway’ to other addictions. Users are often reluctant to seek treatment and the psychiatrist's role in the recognition and management of use is presented.

Abstract
There has recently been renewed interest in novel clinical applications of the anabolic-androgenic steroid (AAS) testosterone and its synthetic derivatives, particularly given with the rising popularity of testosterone supplementation therapy (TST) for the treatment of male hypogonadism. In this manuscript, we provide a brief review of the history of AAS and discuss clinical applications of two of the more well-known AAS: nandrolone and oxandrolone. Both agents exhibit favorable myotrophic/androgenic ratios and have been investigated for effectiveness in numerous disease states. We also provide a brief synopsis of selective androgen receptor modulators (SARMs) and postulate how these orally active, non-aromatizing, tissue-selective agents might be used in contemporary andrology. Currently, the applications of testosterone alternatives in hypogonadism are limited. However, it is tempting to speculate that these agents may one day become accepted as alternatives, or adjuncts, to the treatment of male hypogonadism.

Abstract
Synchronous quadriceps tendon rupture is rare. A 29-year-old man, an amateur weight lifter, taking androgenic-anabolic steroids (AAS), developed sudden onset bilateral pain and swelling of his anterior thighs when attempting to squat 280 kg (620 lb). Examination revealed gross swelling superior to the patella and palpable gaps in both quadriceps tendons. He underwent successful operative repair. MRI revealed a partial tear of the anterior cruciate ligament (ACL) of the right knee. This was not reconstructed. Only a few case reports of the association between AAS and quadriceps rupture exist in the literature, with none to the best of our knowledge in the past 10 years. ACL rupture coexisting is very rare, with only two reported cases.

Abstract
Skeletal muscle tissue has the largest mass in the human body, accounting for 45% of the total weight. Muscle injuries can be caused by bruising, stretching or laceration. The current classification divides such injuries into mild, moderate and severe. The signs and symptoms of grade I lesions are edema and discomfort; grade II, loss of function, gaps and possible ecchymosis; and grade III, complete rupture, severe pain and extensive hematoma. The diagnosis can be confirmed by: ultrasound, which is dynamic and cheap, but examiner dependent; and tomography or magnetic resonance, which gives better anatomical definition, but is static. Initial phase of the treatment can be summarized as the “PRICE” protocol. NSAIDs, ultrasound therapy, strengthening and stretching after the initial phase and range of motion without pain are used in clinical treatment. On the other hand, surgery has precise indications: hematoma drainage and muscle-tendon reinsertion and reinforcement.

Abstract
BACKGROUND Accumulating case reports have described tendon rupture in men who use anabolic-androgenic steroids (AAS). However, no controlled study has assessed the history of tendon rupture in a large cohort of AAS users and comparison nonusers. HYPOTHESIS Men reporting long-term AAS abuse would report an elevated lifetime incidence of tendon rupture compared with non-AAS-using bodybuilders. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Medical histories were obtained from 142 experienced male bodybuilders aged 35 to 55 years recruited in the course of 2 studies. Of these men, 88 reported at least 2 years of cumulative lifetime AAS use, and 54 reported no history of AAS use. In men reporting a history of tendon rupture, the circumstances of the injury, prodromal symptoms, concomitant drug or alcohol use, and details of current and lifetime AAS use (if applicable) were recorded. Surgical records were obtained for most participants. RESULTS Nineteen (22%) of the AAS users, but only 3 (6%) of the nonusers, reported at least 1 lifetime tendon rupture. The hazard ratio for a first ruptured tendon in AAS users versus nonusers was 9.0 (95% CI, 2.5-32.3; P < .001). Several men reported 2 or more independent lifetime tendon ruptures. Interestingly, upper-body tendon ruptures occurred exclusively in the AAS group (15 [17%] AAS users vs 0 nonusers; risk difference, 0.17 [95% CI, 0.09-0.25]; P < .001 [hazard ratio not estimable]), whereas there was no significant difference between users and nonusers in risk for lower-body ruptures (6 [7%] AAS users, 3 [6%] nonusers; hazard ratio, 3.1 [95% CI, 0.7-13.8]; P = .13). Of 31 individual tendon ruptures assessed, only 6 (19%) occurred while weightlifting, with the majority occurring during other sports activities. Eight (26%) ruptures followed prodromal symptoms of nonspecific pain in the region. Virtually all ruptures were treated surgically, with complete or near-complete ultimate restoration of function. CONCLUSION AAS abusers, compared with otherwise similar bodybuilders, showed a markedly increased risk of tendon ruptures, particularly upper-body tendon rupture.

Abstract
Triceps tendon disruption is a rare orthopaedic injury that can lead to poor outcomes if misdiagnosed or managed inappropriately. This case report illustrates the importance of early, precise diagnosis of triceps rupture by clinical and radiological examination with appropriate management. A weightlifter who had fallen while riding his bike presented with pain, swelling around the posterior aspect of the left arm just above the elbow. Physical examination revealed ecchymosis and weakness in elbow extension. A radiograph of the elbow showed a small fleck of bone proximal to the tip of the olecranon. The patient was initially stabilised. Early intervention in the form of primary tendon repair was performed within 3 days and rehabilitation was started. The patient improved significantly to his best possible functional status with Mayo elbow score of 85. Early intervention was the key to better prognosis.

Abstract
Despite the high prevalence of performance-enhancing drug (PED) use, media attention has focused almost entirely on PED use by elite athletes to illicitly gain a competitive advantage in sports, and not on the health risks of PEDs. There is a widespread misperception that PED use is safe or that adverse effects are manageable. In reality, the vast majority of PED users are not athletes but rather nonathlete weightlifters, and the adverse health effects of PED use are greatly underappreciated. This scientific statement synthesizes available information on the medical consequences of PED use, identifies gaps in knowledge, and aims to focus the attention of the medical community and policymakers on PED use as an important public health problem. PED users frequently consume highly supraphysiologic doses of PEDs, combine them with other PEDs and/or other classical drugs of abuse, and display additional associated risk factors. PED use has been linked to an increased risk of death and a wide variety of cardiovascular, psychiatric, metabolic, endocrine, neurologic, infectious, hepatic, renal, and musculoskeletal disorders. Because randomized trials cannot ethically duplicate the large doses of PEDs and the many factors associated with PED use, we need observational studies to collect valid outcome data on the health risks associated with PEDs. In addition, we need studies regarding the prevalence of PED use, the mechanisms by which PEDs exert their adverse health effects, and the interactive effects of PEDs with sports injuries and other high-risk behaviors. We also need randomized trials to assess therapeutic interventions for treating the adverse effects of PEDs, such as the anabolic-androgen steroid withdrawal syndrome. Finally, we need to raise public awareness of the serious health consequences of PEDs.

Abstract
BACKGROUND Distal quadriceps tendon tears are uncommon injuries that typically occur in patients older than 40 years of age, and they have a guarded prognosis. Predisposing factors, prodromal findings, mechanisms of injury, treatment guidelines, and recovery expectations are not well described in high-level athletes. HYPOTHESIS Professional American football players with an isolated tear of the quadriceps tendon treated with timely surgical repair will return to their sport. STUDY DESIGN Case series; Level of evidence, 4. METHODS Fourteen unilateral distal quadriceps tendon tears were identified in National Football League (NFL) players from 1994 to 2004. Team physicians retrospectively reviewed training room and clinic records, operative notes, and imaging studies for each of these players. Data on each player were analyzed to identify variables predicting return to play. A successful outcome was defined as returning to play in regular-season NFL games. RESULTS Eccentric contraction of the quadriceps was the most common mechanism of injury, occurring in 10 players. Only 1 player had antecedent ipsilateral extensor mechanism symptoms. Eleven players had a complete rupture of the quadriceps tendon, and 3 had partial tears. There were no associated knee injuries. All ruptures were treated with surgical repair, 1 of which was delayed after failure of nonoperative treatment. Fifty percent of players returned to play in regular-season NFL games. There was a trend toward earlier draft status for those who returned to play compared with those who did not (draft round, 3.1 ± 2.5 vs. 6.0 ± 2.9, respectively; P = .073). For those who returned to play, the average number of games after injury was 40.9 (range, 12-92). CONCLUSION Quadriceps tendon tears are rare in professional American football players, and they usually occur from eccentric load on the extensor mechanism. Prodromal symptoms and predisposing factors are usually absent. Even with timely surgical repair, there is a low rate of return to play in regular-season games. There is a trend toward early draft rounds for those who successfully return to play.

Abstract
Simultaneous bilateral quadriceps tendon rupture is a very rare injury, which was previously only described in slightly more than 100 cases in the English literature. Occurrence after minor trauma is predominantly associated with certain medical conditions including chronic diseases and long-term use of certain drugs. We report the case of a 61-year-old healthy patient who sustained a simultaneous bilateral quadriceps tendon rupture following minor trauma. Medical history was completely clear except of a long-term nasal corticosteroid medication due to allergic rhinitis.

Abstract
Partial triceps tendon disruptions are a rare injury that can lead to debilitating outcomes if misdiagnosed or managed inappropriately. The clinician should have a high index of suspicion when the mechanism involves a fall onto an outstretched arm and there is resultant elbow extension weakness along with pain and swelling. The most common location of rupture is at the tendon-osseous junction. This case report illustrates a partial triceps tendon disruption with involvement of, primarily, the medial head and the superficial expansion. Physical examination displayed weakness with resisted elbow extension in a flexed position over 90°. Radiographs revealed a tiny fleck of bone proximal to the olecranon, but this drastically underestimated the extent of injury upon surgical exploration. Magnetic resonance imaging is essential to ascertain the percentage involvement of the tendon; it can be used for patient education and subsequently to determine treatment recommendations. Although excellent at finding associated pathology, it may misjudge the size of the tear. As such, physicians must consider associated comorbidities and patient characteristics when formulating treatment plans.

Abstract
Distal brachii triceps tendon rupture is rare. Partial lesions are not so well defined. If functionally they are well tolerated in patients with low functional demand, management guideline is not so clear for sportsmen. To our best knowledge, there is no reported technique for the repair of partial forms. A 28-year-old patient was operated on for a partial triceps rupture. He underwent a transosseous olecranon suture of the tricipital tendon, with a side-to-side suture to the healthy residual tendon. The patient was assessed at 2 years follow-up with the DASH score. He had painless and mobile elbow with no effusion and returned to sport 4 months after his surgical repair. The extension strength was comparable to the healthy side (5/5). The DASH score was 1,7 for global score, and 6,3 for work and sport modules. Partial rupture of brachii triceps tendon is not well tolerated in high functional demand patients. We think that patients should be operated in these situations and may achieve excellent results. Postoperative management is crucial to achieve good results as well as in complete rupture.

Abstract
INTRODUCTION There is an increase in the number of anabolic-steroid (AS)-abusing trainees, who suffer from sports injuries, needing reconstruction surgery. Rupture of the distal biceps brachii tendon is a common injury in this group. PURPOSE The study aimed to investigate the effect of AS abuse in the anatomic reconstruction of the ruptured distal biceps brachii tendon along with an immediate range-of-motion postoperative protocol. METHODS We conducted an observation study of 17 male athletes suffering from distal biceps tendon ruptures. Six of them reported that they abused AS (group A), whereas the non-users comprised group B (n=11). Both groups were treated with the modified single-incision technique with two suture anchors and an immediate active range-of-motion protocol postoperatively. Follow-up was at 4, 16 and 52 weeks postoperatively, with a final follow-up at 24 months. RESULTS Follow-up at 4, 16 and 52 weeks postoperatively showed a statistical significance in favour of group A for therapeutic outcomes concerning flexion, supination, pronation, Disabilities of the Arm, Shoulder and Hand (DASH) Disability Symptom Scores, Mayo Elbow Performance Elbow Scores and isometric muscle strength tests for both flexion and supination. Twenty-four months postoperatively, statistical significance in favour of group A was recorded in isometric muscle strength tests for both flexion and supination and also in DASH Disability Symptom Score. DISCUSSION The results of our study suggest that there is a correlation between the effect of AS and the quicker and better recuperation and rehabilitation observed in group A. Nonetheless, these results must be interpreted with caution, and further in vivo research is needed to confirm these findings.

Abstract
OBJECTIVE The relationship between musculoskeletal injuries and anabolic-androgenic steroids is not well understood. The purpose of our study was to investigate the association between self-reported anabolic-androgenic steroids use and the prevalence of musculoskeletal injuries in a unique group of retired professional football players. DESIGN A general health questionnaire was completed by 2552 retired professional football players. Survey data were collected between May 2001 and April 2003. Results of self-reported musculoskeletal injuries were compared with the use of anabolic-androgenic steroids using frequency distributions and chi2 analyses. RESULTS Of the retired players, 9.1% reported using anabolic-androgenic steroids during their professional career. A total of 16.3% of all offensive line and 14.8% of all defensive line players reported using anabolic-androgenic steroids. Self-reported anabolic-androgenic steroids use was significantly associated (P < 0.05) with the following self-reported, medically diagnosed, joint and cartilaginous injuries in comparison with the nonanabolic-androgenic steroids users: disc herniations, knee ligamentous/meniscal injury, elbow injuries, neck stinger/burner, spine injury, and foot/toe/ankle injuries. There was no association between anabolic-androgenic steroids use and reported muscle/tendon injuries. CONCLUSIONS Our findings demonstrate that an association may exist between anabolic-androgenic steroids use and the prevalence of reported musculoskeletal injury sustained during a professional football career, particularly ligamentous/joint-related injuries. There may also be an associated predisposition to selected types of injuries in anabolic-androgenic steroids users.

Abstract
A histologically normal insertion site does not regenerate following rotator cuff tendon-to-bone repair, which is likely due to abnormal or insufficient gene expression and/or cell differentiation at the repair site. Techniques to manipulate the biologic events following tendon repair may improve healing. We used a sheep infraspinatus repair model to evaluate the effect of osteoinductive growth factors and BMP-12 on tendon-to-bone healing. Magnetic resonance imaging and histology showed increased formation of new bone and fibrocartilage at the healing tendon attachment site in the treated animals, and biomechanical testing showed improved load-to-failure. Other techniques with potential to augment repair site biology include use of platelets isolated from autologous blood to deliver growth factors to a tendon repair site. Modalities that improve local vascularity, such as pulsed ultrasound, have the potential to augment rotator cuff healing. Important information about the biology of tendon healing can also be gained from studies of substances that inhibit healing, such as nicotine and antiinflammatory medications. Future approaches may include the use of stem cells and transcription factors to induce formation of the native tendon-bone insertion site after rotator cuff repair surgery.

Abstract
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.

Abstract
Bilateral simultaneous quadriceps tendon rupture is a relatively rare injury, requiring prompt diagnosis and surgical repair. It is more common in patients older than 50 years and is usually associated with underlying metabolic or inflammatory diseases. Its occurrence is very rare in healthy individuals. We report a case of bilateral quadriceps tendon rupture in a healthy young adult that occurred while he was playing tennis. This patient presented with acute knee swellings, total inability to extend the legs, and a palpable gap above the patella.

Abstract
We reviewed the records of 107 consecutive patients who had undergone surgery for disruption of the knee extensor mechanism to test whether an association existed between rupture of the quadriceps tendon and the presence of a patellar spur. The available standard pre-operative lateral radiographs were examined to see if a patellar spur was an indicator for rupture of the quadriceps tendon in this group of patients. Of the 107 patients, 12 underwent repair of a ruptured patellar tendon, 59 had an open reduction and internal fixation of a patellar fracture and 36 repair of a ruptured quadriceps tendon. In the 88 available lateral radiographs, patellar spurs were present significantly more commonly (p < 0.0005) in patients operated on for rupture of the quadriceps tendon (79%) than in patients with rupture of the patellar tendon (27%) or fracture of the patella (15%). In patients presenting with failure of the extensor mechanism of the knee in the presence of a patellar spur, rupture of the quadriceps tendon should be considered as a possible diagnosis.

Abstract
Rupture of the quadriceps tendon is a rare knee injury. In most cases the tendon ruptures spontaneously without adequate trauma in patients older than 40 years with degenerative changes of the tendon. Suture repair is the only treatment option for acute complete, older ruptures and partial ruptures that do not heal after nonoperative treatment. The type of repair depends on the time of diagnosis and localisation of the rupture. The functional outcome depends on timely repair and early initiation of knee movement and strengthening therapy.

Abstract
Steroids are used outside the realm of competitive athletics in Australia among a wide variety of groups with different motivations and goals. This paper provides an overview of the reasons for use; rates of usage; physical and psychological side effects; and sources of steroids. Issues associated with injecting steroids; their current legal status; and drug education and prevention programmes are reviewed briefly. Research involving identified sub-populations is needed to determine user profiles and prevalence rates of users and potential users. Studies of Australian users are also needed to obtain baseline information on areas of potential harm associated with steroids use, e.g. aggressive behaviour, needle-sharing behaviour, physical side effects and potential for dependency. It is concluded that future deterrence strategies should focus more on demand reduction, rather than supply.

Abstract
From January 1986 to November 1999, 35 patients with 36 traumatic ruptures of the quadriceps tendon, all without medical risk factors, were treated (33 men, 2 women; mean age 55 years). Thirty patients were operated within 14 days after trauma. With an average follow up of 55.4 months (7-168) 29 of 30 still living patients (96.7%) were studied retrospectively. Questionnaire (Lysholm score), physical examination, X-ray of both knees and isokinetic testing were performed. The outcome was significantly (P < 0.001) dependent on the time of operative procedure. Twenty-four patients treated within the first 14 days had 20 excellent and 4 good results, the other 5 one good, 1 satisfying and 3 poor results. Twenty-one of 23 patients (91%) could return to work. The type of repair (direct or transosseous suture with or without augmentation), the kind of postoperative physiotherapy, the age and the body mass index had no influence on the final outcome.

Abstract
Many athletes use drugs, especially anabolic androgenic steroids (AAS), but there are few reports on the endocrinological and pathological changes in AAS abusers. In this study we reported the results of endocrinological examinations in rats administered AAS and also physical changes. We separated 37 male Wistar rats (7 weeks old) into 3 groups: Group A was medicated with nandrolone decanoate, metenolone acetate, and dromostanolone; Group B with nandrolone decanoate and saline; and Group C was given only saline. They were given subcutaneous injections of the medications or the control vehicle once a week for 6 weeks. Medications were stopped for 4 weeks, and then resumed for another 6 weeks. After that, rats were sacrificed. Serum testosterone level in Group A was significantly higher than that in Group C. Serum dihydrotestosterone in Group A was significantly higher than that in both Groups B and C. Serum estradiol-17beta levels in Groups A and B were significantly higher than that in Group C. In pathological evaluation, heart, testis, and adrenal gland were severely damaged. These findings indicate that there is a high degree of risk related to the use of AAS.

Abstract
BACKGROUND To date, no studies document the effect of anabolic steroids on rotator cuff tendons. STUDY DESIGN Controlled laboratory study. HYPOTHESIS Anabolic steroids enhance remodeling and improve the biomechanical properties of bioartificially engineered human supraspinatus tendons. METHODS Bioartificial tendons were treated with either nandrolone decanoate (nonload, steroid, n = 18), loading (load, nonsteroid, n = 18), or both (load, steroid, n = 18). A control group received no treatment (nonload, nonsteroid [NLNS], n = 18). Bioartificial tendons' remodeling was assessed by daily scanning, cytoskeletal organization by staining, matrix metalloproteinase-3 levels by ELISA assay, and biomechanical properties by load-to-failure testing. RESULTS The load, steroid group showed the greatest remodeling and the best organized actin cytoskeleton. Matrix metallo-proteinase-3 levels in the load, steroid group were greater than those of the nonload, nonsteroid group (P <.05). Ultimate stress and ultimate strain in the load, steroid group were greater than those of the nonload, nonsteroid and nonload, steroid groups (P <.05). The strain energy density in the load, steroid group was greater when compared to other groups (P <.05). CONCLUSIONS Nandrolone decanoate and load acted synergistically to increase matrix remodeling and biomechanical properties of bioartificial tendons. CLINICAL RELEVANCE Data suggest anabolic steroids may enhance production of bioartificial tendons and rotator cuff tendon healing in vitro. More research is necessary before such clinical use is recommended.

Abstract
Androgenic-anabolic steroids (AAS) are synthetic derivatives of the male hormone testosterone. They can exert strong effects on the human body that may be beneficial for athletic performance. A review of the literature revealed that most laboratory studies did not investigate the actual doses of AAS currently abused in the field. Therefore, those studies may not reflect the actual (adverse) effects of steroids. The available scientific literature describes that short-term administration of these drugs by athletes can increase strength and bodyweight. Strength gains of about 5-20% of the initial strength and increments of 2-5 kg bodyweight, that may be attributed to an increase of the lean body mass, have been observed. A reduction of fat mass does not seem to occur. Although AAS administration may affect erythropoiesis and blood haemoglobin concentrations, no effect on endurance performance was observed. Little data about the effects of AAS on metabolic responses during exercise training and recovery are available and, therefore, do not allow firm conclusions. The main untoward effects of short- and long-term AAS abuse that male athletes most often self-report are an increase in sexual drive, the occurrence of acne vulgaris, increased body hair and increment of aggressive behaviour. AAS administration will disturb the regular endogenous production of testosterone and gonadotrophins that may persist for months after drug withdrawal. Cardiovascular risk factors may undergo deleterious alterations, including elevation of blood pressure and depression of serum high-density lipoprotein (HDL)-, HDL2- and HDL3-cholesterol levels. In echocardiographic studies in male athletes, AAS did not seem to affect cardiac structure and function, although in animal studies these drugs have been observed to exert hazardous effects on heart structure and function. In studies of athletes, AAS were not found to damage the liver. Psyche and behaviour seem to be strongly affected by AAS. Generally, AAS seem to induce increments of aggression and hostility. Mood disturbances (e.g. depression, [hypo-]mania, psychotic features) are likely to be dose and drug dependent. AAS dependence or withdrawal effects (such as depression) seem to occur only in a small number of AAS users. Dissatisfaction with the body and low self-esteem may lead to the so-called 'reverse anorexia syndrome' that predisposes to the start of AAS use. Many other adverse effects have been associated with AAS misuse, including disturbance of endocrine and immune function, alterations of sebaceous system and skin, changes of haemostatic system and urogenital tract. One has to keep in mind that the scientific data may underestimate the actual untoward effects because of the relatively low doses administered in those studies, since they do not approximate doses used by illicit steroid users. The mechanism of action of AAS may differ between compounds because of variations in the steroid molecule and affinity to androgen receptors. Several pathways of action have been recognised. The enzyme 5-alpha-reductase seems to play an important role by converting AAS into dihydrotestosterone (androstanolone) that acts in the cell nucleus of target organs, such as male accessory glands, skin and prostate. Other mechanisms comprises mediation by the enzyme aromatase that converts AAS in female sex hormones (estradiol and estrone), antagonistic action to estrogens and a competitive antagonism to the glucocorticoid receptors. Furthermore, AAS stimulate erythropoietin synthesis and red cell production as well as bone formation but counteract bone breakdown. The effects on the cardiovascular system are proposed to be mediated by the occurrence of AAS-induced atherosclerosis (due to unfavourable influence on serum lipids and lipoproteins), thrombosis, vasospasm or direct injury to vessel walls, or may be ascribed to a combination of the different mechanisms. AAS-induced increment of muscle tissue can be attributed to hypertrophy and the formation of new muscle fibres, in which key roles are played by satellite cell number and ultrastructure, androgen receptors and myonuclei.
