Management of Patellar Tendinopathy.

Patellar tendinopathy is a common pathology typically seen in athletes involved in repetitive explosive jumping and running activities. Also known as jumpers' knee, it is commonly seen in high-level basketball players. Typically, athletes continue to play with symptoms, which can be aggravated and progress to partial patellar tendon tears. When partial patellar tendon tears occur, prolonged recovery and decreased performance is commonly seen. The pathology and treatment can be frustrating for both the athlete and medical provider. Patellar tendinopathy typically does not involve inflammation but rather microinjury to the tendon fibers, which leads to mucoid degeneration, necrosis, and loss of transitional fibrocartilage. When partial tendon tears do occur, the typical location is posteromedially adjacent to the patella. Treatment involves a stepwise approach starting with nonoperative means, including activity modification, nonsteroidal anti-inflammatories, and physical therapy focused on eccentrics. Extracorporeal shock wave treatments and injections with platelet-rich plasma or bone marrow aspirate concentrate should be considered, with evolving literature to support their use. Ultrasound percutaneous tendon scrapping with a needle supplemented with the aforementioned injections is an emerging treatment option that the authors have found to be helpful, although further studies are required. Surgical intervention is considered after failure of nonoperative treatments, and typically occurs in tears greater than 50% of the tendon thickness and in tendons with increased thickness (>8.8 mm). Open or arthroscopic debridement can be considered, with no studies showing superior outcomes with either technique; however, no high-quality comparison studies exist. The authors prefer an open technique where, much like a bone-patellar tendon-bone harvest, the unhealthy proximal tendon and bone are excised with then closure of the healthy tendon with absorbable sutures. Suture anchor repair may also be used when necessary. In a recent systematic review, surgical management of patellar tendinopathy has been shown to result in improved patient-reported outcomes with return to sport at high levels.1 Treatment for the difficult and sometimes frustrating pathology of patellar tendinopathy continues to evolve, with biologic and less-invasive ultrasound-based treatments showing promise, and surgical intervention providing reliable outcomes.

Facial Injuries in the National Basketball Association.

BACKGROUND: Sport injuries can negatively impact physical and psychological aspects of athletes. There is a gap in the literature regarding facial trauma present in basketball. PURPOSE: The purpose of this study is to identify and describe facial trauma present in the National Basketball Association (NBA). STUDY DESIGN, SETTING, SAMPLE: This is a retrospective cohort study in which the sample (n = 206) consists of players that missed games due to facial injuries in the NBA, the data were collected from a public access online resource. INDEPENDENT VARIABLE: The predictor variables were player position (center, point guard, shooting guard, small forward, and power forward), team conference (Eastern/Western), and if played games occurred in playoff season. MAIN OUTCOME VARIABLES: The primary outcome variable was the injury location (upper, middle, and lower facial third), and the secondary outcome was type of injury (soft tissue/bone fracture). COVARIATES: Player's age, height, weight, and body mass index were collected. ANALYSES: χ2 and logistic regression were calculated to determine associations between predictor and outcome variables. Logistic regression was used to determine if variables were predictive for injury. Odds ratio was also computed for significant results. P value less than .05 (95% confidence interval) was considered statistically significant. RESULTS: A total of 206 players missed games due to facial injuries, and a total of 212 injuries were quantified. The mean age of the injured players was 27.24 ± 4.06 years, mean height (centimeters) was 201 ± 59.31 cm, mean weight (kilograms) was 99.48 ± 12.41 kg, and body mass index was 24.52 ± 1.75 kg/m2. Of the 212 injuries, none of them occurred in the upper facial third, 158 (75%) were in the middle third, and 54 (25%) were in the lower third; 151 of them were fractures (61%) and 61 were soft tissue injuries (29%). Most injuries were concentrated in centers (23%) and power forwards (23%). The most common fracture occurred in the nasal bones (39.2%), and most soft tissue injuries occurred in the eye globes (25%). Almost all injuries occurred during regular season games (97%), and the Eastern conference was slightly predominant (52%). CONCLUSION AND RELEVANCE: Significant facial trauma in the NBA has risen in recent years. The player's position, height, and weight were the primary factors associated with facial trauma in the NBA.

Editorial Commentary: Early Anterior Cruciate Ligament Reconstruction Decreases the Risk of Developing Irreparable Meniscus Tears in Female Athletes.

There has been a substantial increase in the participation of women in sports since the passage of Title IX in 1972. With increased participation has come a rise in athletic injuries, including anterior cruciate ligament (ACL) tears. Numerous factors (modifiable and nonmodifiable) contribute to the 2 to 8 times increased risk of ACL tears in female compared with male athletes. The sports with the greatest risk of ACL injury include cutting sports such as soccer (1.1% per season), basketball (0.9% per season), volleyball, and lacrosse. In addition, female patients have a 33.7% greater risk of a subsequent contralateral ACL tear. Approximately 70% of ACL tears are the result of noncontact injuries. Numerous factors contribute to the increased risk of ACL tears in female athletes, including nonmodifiable (hormonal fluctuations, sex differences in knee geometry) and modifiable risk factors (neuromuscular control). Injury-prevention programs focus on modifiable risk factors and have been shown to be incredibly effective, decreasing the risk of ACL tears up to 50%. ACL tears commonly are associated with meniscus tears, including medial meniscus ramp and lateral posterior root lesions; therefore, thorough assessment is critical to identify this pathology. Early ACL reconstruction (i.e., <12 months following injury) increases the likelihood of being able to repair meniscus tears. Given the much greater risk of ACL tears and lower rate of return to sport in female athletes, this group warrants special attention to identify and treat these injuries earlier and subsequently improve overall outcomes.

Mortality from mental disorders and suicide in male professional American football and soccer players: A meta-analysis.

OBJECTIVE: To determine the risk of mortality from mental disorders and suicide in professional sports associated with repeated head impacts. METHODS: A systematic search was performed in PubMed, Web of Science, Scopus, and SPORTDiscus (since inception to June 8, 2021) to find studies comparing the incidence of mortality from mental disorders or suicide in former or active professional athletes of sports characterized by repeated head impacts vs athletes with no such exposure or the general non-athletic population. RESULTS: Seven retrospective studies of moderate-to-high quality that included data from boxers and from basketball, ice hockey, soccer, and National Football League (NFL) players, respectively (total = 27 477 athletes, 100% male) met all inclusion criteria. Former male NFL players (n = 13 217) had a lower risk of mortality from mental disorders (standard mortality rate [SMR] = 0.30; 0.12-0.77; p = 0.012) and suicide (SMR = 0.54; 0.37-0.78; p < 0.001) than the general population. This finding was also corroborated in male soccer players (n = 13,065; SMR = 0.55; 0.46-0.67; p < 0.001). Male athletes participating in sports associated with repeated head impacts (n = 18,606) had also a lower risk of all-cause, cardiovascular disease (CVD), and cancer mortality (all p < 0.01) than the general population. CONCLUSIONS: Participation of male athletes in American football or soccer at the professional level might confer a certain protective effect against mortality from mental disorders or suicide, besides its association with a lower risk of all-cause, CVD, or cancer-related mortality.

Local dynamic stability of the lower-limb as a means of post-hoc injury classification.

Since most sporting injuries occur at the lower extremity (50% to 66%) and many of those injuries occur at the knee (30% to 45%), it is important to have robust metrics to measure risk of knee injury. Dynamic measures of knee stability are not commonly used in existing metrics but could provide important context to knee health and improve injury screening effectiveness. This study used the Local Dynamic Stability (LDS) of knee kinematics during a repetitive vertical jump to perform a post-hoc previous injury classification of participants. This study analyzed the kinematics from twenty-seven female collegiate division 1 (D1) soccer, D1 basketball, and club soccer athletes from Auburn University (height = 171 ± 8.9cm, weight = 66.3 ± 8.6kg, age = 19.8 ± 1.9yr), with 7 subjects having sustained previous knee injury requiring surgery and 20 subjects with no history of injury. This study showed that LDS correctly identified 84% of previously injured and uninjured subjects using a multivariate logistic regression during a fatigue jump task. Findings showed no statistical difference in kinematic position at maximum knee flexion during all jumps between previously injured and uninjured subjects. Additionally, kinematic positioning at maximum knee flexion was not indicative of LDS values, which would indicate that future studies should look specifically at LDS with respect to injury prevention as it cannot be effectively inferred from kinematics. These points suggest that the LDS preserves information about subtle changes in movement patterns that traditional screening methods do not, and this information could allow for more effective injury screening tests in the future.

Analysis of different injuries of basketball players based on surface electromyography / Análise de diferentes lesões em jogadores de basquete com base na eletromiografia de superfície / Análisis de diferentes lesiones de jugadores de baloncesto basado en electromiografía superficial

ABSTRACT Assessing the performance of basketball players is very important in the implementation of technical training programs. The application of electromyography (EMG) in basketball players is still relatively small. The evaluation of athletes' muscle state index by EMG can guide sports training. This study used surface electromyography to test and compare EMG data, analyze muscle discharge timing, contribution rate and integral EMG value of the turning movement, aiming to explore the prevention mechanism of different types of injury affecting basketball players. The synchronous measurement model of EMG signal and plantar pressure curve in jump shot process of basketball players is established to deepen coaches' understanding of jump shot movement rules and guide athletes to conduct scientific jump shot training. The research shows that the incidence of knee joint injury is relatively high in basketball players. Patella strain and softening, knee meniscus injury and cruciate ligament injury are the main types of injury, and there is no difference between genders.

RESUMO A avaliação do desempenho dos jogadores de basquete é muito importante na implementação de programas de treinamento técnico. A aplicação de eletromiografia (EMG) no basquetebol ainda é relativamente pequena. A avaliação do índice de estado muscular dos atletas por EMG pode guiar o treinamento esportivo. Este estudo utilizou a eletromiografia de superfície para testar e comparar os dados da EMG, analisar o tempo de descarga muscular, a taxa de contribuição e o valor integral da EMG do movimento de rotação, com o objetivo de explorar o mecanismo de prevenção de diferentes tipos de lesões entre jogadores de basquete. O modelo de medição síncrona do sinal EMG e da curva da pressão plantar no processo de arremessos por parte de jogadores de basquete é estabelecido para aprofundar a compreensão dos treinadores sobre as regras de arremessos e guiar atletas a realizar treinamentos de arremessos com bases científicas. A pesquisa mostra que a incidência de lesão nas articulações do joelho é relativamente alta entre os jogadores de basquete. Luxação e amolecimento de patela, lesão de menisco e lesão do ligamento cruzado são os principais tipos de lesão, e não há diferença entre generosos sexos masculino e feminino.

RESUMEN La evaluación del desempeño de los jugadores de baloncesto es muy importante en la implementación de programas de entrenamiento técnico. La aplicación de electromiografía (EMG) en el baloncesto aun es relativamente pequeña. La evaluación del índice de estado muscular de los atletas por EMG puede guiar el entrenamiento deportivo. Este estudio utilizó la electromiografía de superficie para testear y comparar los datos de la EMG, analizar el tiempo de descarga muscular, la tasa de contribución y el valor integral de la EMG del movimiento de rotación, con el objetivo de explorar el mecanismo de prevención de diferentes tipos de lesiones entre jugadores de baloncesto. El modelo de medición síncrona de la señal EMG y de la curva de la presión plantar en el proceso de lanzamientos por parte de jugadores de baloncesto es establecido para profundizar la comprensión de los entrenadores sobre las reglas de lanzamientos y guiar a los atletas a realizar entrenamientos de lanzamientos con bases científicas. La investigación muestra que la incidencia de lesión en las articulaciones de la rodilla es relativamente alta entre los jugadores de baloncesto. Luxación y ablandamiento de rótula, lesión de menisco y lesión del ligamento cruzado son los principales tipos de lesión, y no hay diferencia entre los sexos.

Bilateral Popliteal Artery Entrapment Syndrome in a Young Female NCAA Division-I Collegiate Basketball Player: A Case Report.

CASE: Popliteal artery entrapment syndrome (PAES) is rarely on the differential for exertional lower extremity pain in the young athlete. This article illustrates a case of a 20-year-old female National Collegiate Athletic Association (NCAA) Division-I college basketball player who was diagnosed with PAES after conservative treatment of medial tibial stress syndrome and comprehensive evaluation for chronic exertional compartment syndrome. She received bilateral popliteal artery releases through a posterior approach and made an asymptomatic return to Division-I collegiate basketball. CONCLUSION: PAES is a rare potentially limb-threatening disease that must be included on the differential of young athletes who present with exertional lower extremity pain.

Performance and Return to Sport After Hip Arthroscopy in the National Basketball Association.

PURPOSE: To determine: (1) return to sport (RTS) rate in National Basketball Association (NBA) players following hip arthroscopy, (2) postoperative career length and games per season, (3) pre- and postoperative performance, and (4) postoperative performance compared with control players. METHODS: NBA athletes who underwent hip arthroscopy and matched controls were identified. RTS was defined as playing in at least 1 game after surgery. Player efficiency ratings were used for performance evaluation. Continuous variables of each group were compared using a 2-tailed paired samples Student t test for normally distributed data. χ2 was used to analyze categorical data. RTS was used as the primary outcome with statistical significance defined by a P value < .05. A Bonferroni correction was used to control for the remaining multiple comparisons with statistical significance defined by a P value ≤.008. RESULTS: Twenty-three players (24 hips) were analyzed (mean age 27.5 ± 3.1 years; mean experience in the NBA 5.8 ± 2.8 years at time of surgery). Small forwards (n = 8, 33.3%) represented the largest proportion of players that underwent hip arthroscopy. Twenty players (21 surgeries, 87.5%) were able to RTS in NBA at an average of 5.7 ± 2.6 months. The overall 1-year NBA career survival rate of players undergoing hip arthroscopy was 79.2%. Players in the control group (5.2 ± 3.5 years) had a similar career length as (P = .068) players who underwent surgery (4.4 ± 3.0 years). There was no significant (P = .045) decrease in games per season following surgery. There was no significant difference in performance postoperatively compared with preoperatively (P = .017) and compared with matched controls following surgery (P = .570). CONCLUSIONS: The RTS rate for NBA athletes after hip arthroscopy is high. There was no decrease in games played, career lengths, or performance following hip arthroscopy in NBA players versus preoperatively and matched controls. LEVEL OF EVIDENCE: Level III case-control study.

Successful fifth metatarsal bulk autograft reconstruction of thermal necrosis post intramedullary fixation.

Reamed intramedullary (IM) screw fixation for proximal fifth metatarsal fractures is technically challenging with potentially devastating complications if basic principles are not followed. A case of an iatrogenic fourth-degree burn after elective reamed IM screw fixation of a proximal fifth metatarsal fracture in a high-level athlete is reported. The case was complicated by postoperative osteomyelitis with third-degree soft-tissue defect. This was successfully treated with staged autologous bone graft reconstruction, tendon reconstruction, and local bi-pedicle flap coverage. The patient returned to competitive-level sports, avoiding the need for fifth ray amputation. Critical points of the IM screw technique and definitive reconstruction are discussed. Bulk autograft reconstruction is a safe and effective alternative to ray amputation in segmental defects of the fifth metatarsal.Level of evidence V.

Return to play and performance after shoulder instability in National Basketball Association athletes.

HYPOTHESIS: We hypothesized that players in the National Basketball Association (NBA) who sustained a shoulder destabilizing injury could return to play (RTP) successfully at a high rate regardless of treatment type. METHODS: We used publicly available data to identify and evaluate 50 players who sustained an in-season shoulder instability event (subluxation/dislocation) while playing in the NBA. Demographic variables, return to NBA gameplay, incidence of surgery, time to RTP, recurrent instability events, and player efficiency rating (PER) were collected. Overall RTP was determined, and players were compared by type of injury and mode of treatment. RESULTS: All players (50/50) returned to game play after sustaining a shoulder instability event. In those treated nonoperatively, athletes who sustained shoulder subluxations returned after an average of 3.6 weeks, compared with 7.6 weeks in those who sustained a shoulder dislocation (P = .037). Players who underwent operative management returned after an average of 19 weeks. Athletes treated operatively were found to have a longer time interval between a recurrent instability event (70 weeks vs. 28.5 weeks, P = .001). CONCLUSION: We found 100% rate of RTP after a shoulder instability event in an NBA athlete. Players who experience shoulder dislocations were found to miss more time before RTP and were more likely to undergo surgical intervention compared with those who experienced a subluxation. Surgical repair maintained a longer interval between recurrent instability. Future investigations should aim to evaluate outcomes based on surgical procedures and identify possible risk factors predictive of recurrent instability or failure to RTP.

Hip biomechanics differ in responders and non-responders to an ACL injury prevention program.

PURPOSE: To investigate the differences in demographic, anthropometric, biomechanical, and/or performance variables between those that do (responders) and do not (non-responders) exhibit reductions in knee abduction moments after an anterior cruciate ligament injury prevention program (ACL-IPP). METHODS: Forty-three adolescent female athletes completed biomechanical (3D motion analysis of a drop vertical jump) and performance testing before and after randomization into a 6-week ACL-IPP. Participants were classified into responders and non-responders based on their level of reduction of knee abduction moment from pre- to post-test. RESULTS: Compared to non-responders, responders exhibited increased hip adduction excursion at baseline (p = 0.02) and trended towards attending more training sessions (p = 0.07) and participating in soccer and not basketball (p = 0.07). Responders also showed greater improvements in hip flexion angles (p = 0.02) and moments (p < 0.001), and knee abduction angles (p < 0.001) and excursions (p = 0.001). There were no significant differences in age or experience with prior injury prevention programs (n.s.). CONCLUSIONS: After an ACL-IPP, athletes that exhibit the greatest reduction in knee abduction moments exhibit greater hip adduction excursion at baseline and show corresponding improvements in hip flexion and knee abduction kinematics and hip flexion moments. These results can help clinicians prospectively identify individuals that may not respond to an ACL-IPP and target individualized training for those at risk of injury. LEVEL OF EVIDENCE: I. CLINICAL TRIAL REGISTRATION NUMBER: Clinicaltrials.gov NCT02530333.

Effect of Shoulder Stabilization on Career Length and Performance in National Basketball Association Athletes.

PURPOSE: Untreated episodes of shoulder instability can have major consequences on athletic careers. Operative shoulder stabilization reduces the rate of recurrent instability and allows for high rates of return to sport (RTS). Basketball players who experience an episode of instability have high rates of recurrence, though little is known about postoperative player performance. The purpose of this study was to identify the impact of shoulder instability and surgical stabilization on player performance and career lengths in the National Basketball Association (NBA). METHODS: NBA players who had episodes of shoulder instability between 1994-2014 were identified using the NBA Injury Surveillance and Analytics Database. Players were stratified according to operative versus nonoperative treatment of shoulder instability. Two demographic- and performance-matched controls were chosen for each test subject. Univariate analyses were used to compare pre- and postoperative player performance metrics. Survival analysis was used to assess the effect of shoulder surgery on postoperative career lengths. RESULTS: Fifty athletes were identified, 46 (92.0%) returned to play in the NBA. Compared to controls, there was no significant difference in postoperative performance according to either 1- or 3-year averages. Survival analysis demonstrated no significant difference in postoperative career lengths between athletes with a history of shoulder surgery for instability and matched controls. CONCLUSION: NBA players return to professional basketball in high numbers following orthopedic surgery for shoulder instability. Shoulder instability may not be a career-altering event, as there are highly effective methods of shoulder stabilization available to athletes.

Return to Play After Bipolar Patellofemoral Osteochondral Allograft Transplantation for a Professional Basketball Player: A Case Report.

CASE: Extensive and multiple symptomatic chondral lesions in the knee of a professional athlete presents unique challenges when considering optimal management. We present the case of a professional National Basketball Association player with symptomatic and extensive patellofemoral chondral lesions, who failed 24 months of nonoperative management and was treated surgically with bipolar patellofemoral osteochondral allograft transplantation (OCA) consisting of 3 large grafts to the patella, medial trochlea, and lateral trochlea. The player was able to return to his preinjury level of play 10 months postoperatively and remains asymptomatic at same level of play 3 years after surgery. Postoperative magnetic resonance imaging at 16 months demonstrated good restoration of the articular architecture of the patellofemoral joint. CONCLUSIONS: Bipolar OCA treatment for extensive chondral patellofemoral injury may be considered in high-level, high-demand athletes who wish to return to play professionally.

Locked Thumb Metacarpophalangeal Joint Caused by Entrapment of the Sesamoid Bone: A Report of 2 Cases.

Locked thumb metacarpophalangeal joint caused by entrapment of the sesamoid bone is an uncommon entity. The intact volar plate, strong ligamentous attachment between the sesamoid bone and the joint, and altered axis of inserted muscle all contribute to failure of closed reduction. The patient's history, clinical presentation, and plain radiographic findings are all important clues to diagnosing this rare disease. We describe 2 patients with a similar mechanism of injury, where the sesamoid bones were displaced into the thumb metacarpophalangeal joint causing lock thumb. The anatomy, pathophysiology, and surgical management of the patients are also described and discussed. Both patients were successfully treated with meticulous open reduction.

Evaluation of the effect of elastic bandage on the ankle basketball players with and without chronic instability / Avaliação do efeito da bandagem elástica no tornozelo de jogadores de basquete com e sem instabilidade crônica / Evaluación del efecto del vendaje elástica en el tobillo de atletas de baloncesto con y sin inestabilidad crónica

INTRODUCTION: Basketball is a sport that requires good motor coordination as well as intense and multidirectional movements. Chronic ankle instability affects about 40% of patients who have sustained a sprain injury. In order to minimize the effects of this dysfunction, functional elastic tape has been widely used due to its mechanical properties, having some positive effects on athletes' functional performance. OBJECTIVE: To evaluate the effect of elastic tapes on the ankles of basketball players with and without chronic instability. METHOD: Thirteen athletes from a varsity basketball team of both sexes, aged between 18 and 30 years (23.2 ± 3.2 years), who had been playing the sport for at least one year and trained at least twice a week. The subjects were assessed using the anterior drawer test for the presence or absence of chronic ankle instability and in three different situations: placebo, elastic tape and control, and the order of use of the implements was randomly determined, using the Star Excursion Balance Test (SEBT) to assess the ankle stability of these athletes. RESULTS: Among the eight directions proposed in the SEBT, there was statistical significance in the difference in three directions for the placebo method in comparison to elastic taping and control. There was no statistical significance in the difference in four directions between the assessments, and there was no statistical significance in the difference in all directions between the control and elastic tapes. CONCLUSION: It can be inferred from the study that elastic taping does not have positive effects on joint stability in athletes with and without chronic instability, taking into account their functionality.

Femoroacetabular Impingement in Professional Basketball Players: Return to Play, Career Length, and Performance After Hip Arthroscopy.

BACKGROUND: Previous studies have demonstrated that hip arthroscopy is an effective treatment for symptomatic femoroacetabular impingement (FAI) in professional athletes across a variety of sports. However, the return-to-play rates and postoperative performance of elite basketball players after hip arthroscopy are currently unknown. PURPOSE: To determine return-to-play rates and postoperative performance among professional basketball athletes after hip arthroscopy. STUDY DESIGN: Case series; Level of evidence, 3. METHODS: Eighteen professional basketball players underwent hip arthroscopy (24 hips) for symptomatic FAI between 2001 and 2016 by a single surgeon. Return to play was defined as competing in a single professional game of equal level after surgery. Data were retrospectively obtained for each player from basketball-reference.com , ESPN.com , eurobasket.com, and individual team websites. Matched controls were selected from the websites to compare performances. RESULTS: The mean age at the time of surgery was 25.6 years, and the mean body mass index was 24.4 kg/m2. All players returned to their previous levels of competition, with a mean number of 4 seasons played after surgery (median, 3; range, 1-12). The mean ± SD time between the date of surgery and return to a professional game was 7.1 ± 4.4 months. There was no change in player efficiency rating when pre- and postinjury performance were compared. When compared with controls, players undergoing surgery also had no significant decline in player efficiency rating. CONCLUSION: Elite basketball athletes who undergo hip arthroscopy for the treatment of FAI return to their presurgical levels of competition at a high rate. These athletes demonstrate no significant overall decrease in performance upon their return to play.
