Muscle rupture sports

PURPOSE: Quadriceps dysfunction is ubiquitous after anterior cruciate ligament reconstruction, especially when using bone-patellar tendon-bone (BPTB) autografts. The role of patellar tendon hypertrophy after graft harvest on knee extensor strength is unknown. The purpose of this study was to determine the predictive ability of patellar tendon (PT) and quadriceps muscle (Quad) cross-sectional area (CSA) on knee extensor strength 1-2 months after ACLR using BPTB autografts. METHODS: This is a cross-sectional analysis of a cohort 1-2 months after ACLR using BPTB autograft...

Acute distal biceps injuries clinically present with sudden pain and acute loss of flexion and supination strength. The main injury mechanism occurs during the eccentric load of the biceps. The hook test is the most significant examination test, presenting the highest sensibility and specificity for this lesion. Magnetic resonance imaging, the gold standard imaging test, can provide information regarding integrity and identify partial and/or complete tears. The surgical treatment uses an anterior or double approach and several reattachment techniques...

Arthroscopy and endoscopic hip surgery have attracted increasing attention in the orthopedic field. In the case of arthroscopy, portals and their relationships with neurovascular bundle structures at risk are well established. However, studies on endoscopic portals used for the repair of hamstring tendon injuries are insufficient. Hamstring injuries are the most common muscle injury in sports medicine, and up to 12% can present as a tendon rupture. Endoscopic surgery is advantageous because it has a lower rate of bleeding and avoids excessive handling of the gluteal muscles...

Sports medicine is generally associated with soft tissue injuries including muscle injuries, meniscus and ligament injuries, tendon ruptures, tendinopathy, rotator cuff tears, and tendon-bone healing during injuries. Tendon and ligament injuries are the most common sport injuries accounting for 30-40% of all injuries. Therapies for tendon injuries can be divided into surgical and non-surgical methods. Surgical methods mainly depend on the operative procedures, the surgeons and postoperative interventions. In non-surgical methods, cell therapy with stem cells and cell-free therapy with secretome of stem cell origin are current directions...

PURPOSE: To evaluate the clinical outcomes of primary or revision ACL reconstruction (ACLR) after contralateral hamstring autografts versus ipsilateral hamstring autograft harvest. METHODS: Three databases (MEDLINE, PubMed and EMBASE) were searched from inception to April 27th, 2023 for studies investigating contralateral hamstring autografts in primary or revision ACLR. The authors adhered to the PRISMA and R-AMSTAR guidelines as well as the Cochrane Handbook for Systematic Reviews of Interventions...

Although muscle injuries represent the most frequent injury in professional football, isolated complete distal ruptures of the rectus femoris (RF) muscle are rare, and there is no consensus on their treatment and return to play (RTP). In this article, we report a clinical case of successful non-surgical management of an RF grade 4c muscle injury in a professional football player, in which the athlete was able to RTP 21 weeks after the injury, had no re-injury >1 year after RTP, and is playing at an elite level in the Portuguese Football First League...

PURPOSE: To evaluate the current literature on the effects of anatomic changes caused by the Latarjet procedure and to identify areas for future research. METHODS: English-language studies that addressed the consequences of anatomic alterations after the open Latarjet procedure were included. Articles written in languages other than English, reviews, and case reports were excluded. Titles and abstracts were screened by 2 authors. Studies that met the inclusion criteria were screened by the same authors...

UNLABELLED: An elastic band wrapped around the distal thighs has recently been proposed as a method for reducing dynamic knee valgus (medial movement of the knee joint in the frontal/coronal plane) while performing squats. The rationale behind this technique is that, by using an external force to pull the knees into further knee valgus, the band both exaggerates the pre-existing movement and provides additional local proprioceptive input, cueing individuals to adjust their knee alignment...

PURPOSE: To investigate the combinations of variables that comprise the biopsychosocial model domains to identify clinical profiles of risk and protection of second anterior cruciate ligament injury. METHODS: One hundred and forty-five patients for return-to-sport testing after anterior cruciate ligament (ACL) reconstruction (ACLR) were contacted, and 97 were deemed eligible. All were evaluated between 6 and 24 months and followed up for 2 years. Participants answered the International Knee Documentation Committee (IKDC) and Anterior Cruciate Ligament-Return to Sport after Injury Scale (ACL-RSI), performed the postural stability assessment using the Biodex Balance System, and assessed muscle strength at 60° and 300°/s on the isokinetic dynamometer...

BACKGROUND: High tendon strain leads to sub-rupture fatigue damage and net-catabolic signaling upon repetitive loading. While high levels of tendon strain occur in adolescent athletes at risk for tendinopathy, a direct association has not yet been established. Therefore, in this prospective longitudinal study, we examined the hypothesis that adolescent athletes who develop patellar tendon pain have shown increased levels of strain in advance. METHODS: In 44 adolescent athletes (12-17 years old), patellar tendon mechanical properties were measured using ultrasonography and inverse dynamics at four time points during a season...

BACKGROUND AND PURPOSE: One of the best alternatives for the treatment of meniscal injuries in relation to surgical procedures, is exercise. This case report aimed to describe the effects of isokinetic training and a neuromuscular/proprioceptive exercise program on muscle performance and physical function in an individual after a rupture of the posterior horn of the medial meniscus. STUDY DESIGN: Case report. CASE DESCRIPTION: A 40-year-old man injured his right knee during a soccer match, with a partial lesion of the medial meniscus confirmed by magnetic resonance imaging...

INTRODUCTION: Core abdominal injury (CAI) is a broad term that describes injuries resulting from repetitive loading of the pubis that leads to inflammation, rupture, or destabilization of the core muscles from the pubic bone. There is no clear recommendation on the surgical approach to CAI. We aimed to describe how hernia surgeons within the Abdominal Core Health Quality Collaborative (ACHQC) address this problem surgically and the short-term outcomes. METHODS: We queried the ACHQC registry for patients undergoing surgery for isolated CAI and concomitant inguinal hernias (IH) and CAI...

PURPOSE: To perform a systematic review of the clinical outcomes of anterior cruciate ligament reconstruction using either contralateral or ipsilateral tendon autografts. METHODS: A systematic review of literature published from inception to December 9, 2022, in multiple databases (PubMed, Embase, Scopus, and the Cochrane Library) was conducted in accordance with the 2020 PRISMA (Preferred Reporting Items for Systematic Reviews) guidelines. Two reviewers independently screened the literature, extracted the data, performed the risk of bias assessment and assessed the study quality...

BACKGROUND: Patients report psychological barriers as important when returning to sport, however, psychological outcome measures are seldom included in return to sport (RTS) assessment. There is a need for clinical trials to integrate psychological patient-reported outcomes (PROs) in return to sport batteries assessing patients treated with ACL reconstruction. OBJECTIVE: The aim of this study was to determine the association between passing clinical tests of muscle function and psychological PROs and sustaining a second ACL injury in patients who RTS after primary ACL reconstruction...

Groin pain is a common issue in athletes, with a particularly high incidence in male soccer players. Adductor muscles are the most involved site of the groin, accounting for up to one-fourth of muscle injuries of that region. Physical therapy and rehabilitation programs for adductor-related groin pain using active exercises are effective in getting athletes back to sport. However, the return-to-play time varies according to the injury severity. Minor lesions can recover in 1-2 weeks, while severer injuries require 8-12 weeks...

Achilles' tendon (AT) injuries such as ruptures and tendinopathies have experienced a dramatic rise in the mid- to older-aged population. Given that the AT plays a key role at all stages of locomotion, unsuccessful rehabilitation after injury often leads to long-term, deleterious health consequences. Understanding healthy in vivo strains as well as the complex muscle-tendon unit interactions will improve access to the underlying aetiology of injuries and how their functionality can be effectively restored post-injury...

BACKGROUND: Animal models play an important role in studying posttraumatic osteoarthritis (PTOA) disease progression. Different models exist, such as destabilization of the medial meniscus (DMM), anterior cruciate ligament (ACL) surgical transection (ACLs), and noninvasive ACL rupture. PURPOSE: To study the effects of PTOA on nociception in 3 different murine models and to relate these findings to macroscopic and microscopic changes in joint tissues. STUDY DESIGN: Controlled laboratory study...

INTRODUCTION: Pectoralis major injury is a rare injury. Its incidence increases with sports related activities. Early diagnosis is essential to obtain a satisfactory functional outcome. We present in this paper a case of 39-year-old male patient presenting with missed chronic the right pectoralis major muscle injury treated with anatomic surgical reinsertion of the muscle tendon to the humerus. CASE REPORT: A 39-year-old male bodybuilder patient felt a snap in his right dominant shoulder while performing bench press...

The aim was to present a descriptive 10-season summary of injury data from all teams of a professional football club using a heat map approach. Injuries and exposure time were registered according to the FIFA consensus in all men's and women's teams from Athletic Club over 10 seasons. A team-by-injury table was created, showing the incidence, median severity, and burden in each cell. Cells were coloured based on the injury burden value using a green - yellow-red gradient (lowest to highest). The highest overall injury burden was found in the women's 2nd and 1st teams and the men's U(under)17 team (>200 days lost/1000 h)...

BACKGROUND: Selective neurectomy or muscle resection techniques for calf reduction conventionally focuses on the gastrocnemius muscle. Nonetheless, the underlying soleus muscle plays an important role in muscular calf hypertrophy. In our experience, the results of calf reduction have been suboptimal in patients with severe muscular calf hypertrophy who had undergone gastrocnemius muscle resection only. This study aimed to describe a new calf reduction method that employs concurrent gastrocnemius muscle resection and soleus muscle neurectomy using an endoscope-assisted single-incision approach in patients with severe muscular calf hypertrophy...
