Wang P, Baek S. Early Warning of Basketball Injury Risk Based on Attribute Reduction Algorithm. COMPUTATIONAL INTELLIGENCE AND NEUROSCIENCE 2022; 2022:6981246. [PMID: 35463287 PMCID: PMC9020901 DOI: 10.1155/2022/6981246] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Revised: 03/20/2022] [Accepted: 04/04/2022] [Indexed: 12/02/2022]
Abstract
Basketball is one of the students' favorite ball games, and it is also one of the most popular sports for college students to carry out after class. Especially in recent years, with the spread of NBA culture around the world and the extensive development of CUBA in domestic colleges and universities, Yao Ming has appeared in China to compete in the NBA and achieve brilliant achievements. With the increasing investment in the number of basketball venues, basketball itself, as a sport with low dependence on venues, equipment, and people, has the characteristics of economy, convenience, and remarkable sports effect compared with other sports. College students' basketball skills, basketball awareness, and love for basketball are increasing day by day. Attribute reduction algorithm is one of the core contents of knowledge discovery, which describes whether every attribute in the attribute set of information system is necessary and how to delete unnecessary knowledge. Based on the attribute reduction algorithm, this paper studies the early warning of basketball injury risk. The basketball injury can not only make athletes unable to participate in training or competition, but even cripple or lose their lives, which hinders the normal development of sports. Therefore, we should make a comprehensive and objective analysis of sports training to find out the causes of sports injuries, so as to prevent sports injuries. This algorithm takes the attribute frequency as the heuristic information and solves the attribute selection problem when the attribute frequency is the same.

Abstract
Purpose The aim this study was to provide an epidemiological injury analysis of the National Basketball Association, detailing aspects such as frequency rate, characteristics and impact on performance (missed games), including COVID-19 related and non-related injuries. Methods A retrospective study was conducted from the 2017–18 to 2020–2021 season. Publicly available records from the official website of the National Basketball Association were collected, including player’s profiling data, minutes played per game until the injury occurred, unique injuries and injury description [location (body area), diagnosis (or mechanism)], and missed games due to injury. Results A total of 625 players and 3543 unique injuries were registered during the period analyzed. There was an increased incidence of missed games and unique injuries ratios, from 2017–18 until 2020–21, even when excluding COVID-19 related cases. The main body areas of injuries corresponded to lower body injuries, specifically knee, ankle and foot. The tendon/ligament group, for both games missed and unique injuries, showed the higher ratios (1.16 and 0.21, respectively), followed by muscle (0.69 and 0.16, respectively) and bones (0.30 and 0.03, respectively). Irrespective of season, the higher percentage of unique injuries occurred in the group of players playing in the 26–35 minutes, followed by the 16–25 minutes played. Guards showed the highest injury ratios compared to other playing positions. Most injuries and missed games due to injury occurred from mid-season to the end of the regular season. The majority of both injuries and missed games were concentrated in the two central experience groups (from 6 to 15 years). Conclusions Despite previous efforts to better understand injury risk factors, there has been an increase in unique injuries and missed games. The distribution by body area, type of injury, when they occurred, minutes played and outcomes by play position, age a or years of experience vary between season and franchises.

Abstract
Sports injury is a subject that every athlete will face, and it is the easiest to happen in training and competition, especially for basketball players. Moreover, the excessive fatigue caused by sports not only reduces the person's ability to play sports, but also it reduces the person's participation in normal training and competition. Sugar and fat play a dominant role in energy metabolism, while protein only plays an auxiliary role. For competitive sports, sugar is the most important energy, and the main components of honey are glucose and fructose. Therefore, this paper attempts to explore the effect of honey on the physical recovery and nutritional supplement of basketball players. In this paper, 10 basketball players in our city were selected as the experimental objects and the data of their physiological and biochemical indexes were analyzed. The results showed that the average hemoglobin of the experimental group decreased from 14.45 g·100 ml-1 in the first week to 13.23 g·100 ml-1 in the second week, increased to 14.25·100 ml-1 in the third week, and increased to 15.79.100 ml-1 in the fourth week. Adding honey can improve the content of HB and CK of basketball players in higher vocational colleges and reduce the increase of BUN, to slow down fatigue and accelerate the speed of physical recovery.

Abstract
IMPORTANCE There is limited research investigating injury and illness among professional basketball players during their rookie season. By improving the understanding of injury incidence and risk specific to rookie players, sports medicine clinicians may be able to further individualize injury mitigation programs that address the unique needs of rookie players. OBJECTIVE To compare incidence and rate ratio (RR) of injury and illness among professional National Basketball Association (NBA) players in their rookie season with veteran players and to explore the association of sustaining an injury rookie season with career longevity. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study used an online data repository and extracted publicly available data about NBA players between the 2007 and 2008 season to the 2018 and 2019 season. Available data for initial injury and all subsequent injuries were extracted during this time frame. EXPOSURES Injury and illness based on injury status during the rookie season of professional NBA players. MAIN OUTCOMES AND MEASURES Injury and illness incidence and RR. Association of injury during the rookie season with career longevity was assessed via Poisson regressions. RESULTS Of the 12 basketball seasons analyzed, 904 NBA players were included (mean [SD] age, 24.6 [3.9] years; body mass index, 24.8 [1.8]). The injury and illness incidence for rookie players was 14.28 per 1000 athlete game exposures (AGEs). Among all body regions, ankle injuries had the greatest injury incidence among players injured during their rookie season (3.17 [95% CI, 3.15-3.19] per 1000 AGEs). Rookie athletes demonstrated higher RR compared with veterans across multiple regions of the body (ankle: 1.32; 95% CI, 1.12 to 1.52; foot/toe: 1.29; 95% CI, 0.97 to 1.61; shoulder/arm/elbow: 1.43; 95% CI, 1.10 to 1.77; head/neck: 1.21; 95% CI, 0.61 to 1.81; concussions: 2.39; 95% CI, 1.89 to 2.90; illness: 1.14; 95% CI, 0.87 to 1.40), and demonstrated a higher rate of initial injuries compared with veteran players (1.41; 95% CI, 1.29 to 1.53). Players who sustained an injury rookie season demonstrated an unadjusted decrease in total seasons played (-0.4 [95% CI, -0.5 to -0.3] log years; P < .001), but this decrease was not observed within adjusted analysis (0.1 [95% CI, -0.1 to 0.2] log years; P = .36). CONCLUSIONS AND RELEVANCE In this study, rookie athletes demonstrated the highest injury incidence at the ankle and increased RR across multiple regions. These findings may reflect differences in preseason conditioning or load variables impacting rookie athletes and warrant further investigation. Future research is needed to determine the association of cumulative injury burden vs a singular injury event on career longevity.

[PMID: 34086814 PMCID: PMC8177521 DOI: 10.1371/journal.pone.0252839] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2021] [Accepted: 05/23/2021] [Indexed: 11/18/2022] Open
Abstract
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.

Abstract
The ideal timing to implement anterior cruciate ligament injury prevention programs with respect to maturation is unclear. The purpose of this study was to investigate the effects of an injury prevention program on knee mechanics in early-, late-, and post-pubertal females. In the study, 178 adolescent female basketball players were assigned to six groups: early-pubertal training, early-pubertal control, late-pubertal training, and late-pubertal control, post-pubertal training, and post-pubertal control. The training groups performed an injury prevention program for six months. Medial knee displacement, knee flexion range of motion, and the probability of high knee abduction moment were assessed before and after the training period. After the six-month training period, medial knee displacement was significantly increased in the early-pubertal control group whereas it was unchanged in the early-pubertal training group. Knee flexion range of motion was significantly decreased in the early-pubertal control group whereas it did not change in the early-pubertal training group. The probability of high knee abduction moment was increased in the early-pubertal control group whereas it was unchanged in the earl-pubertal training group. The probability of high knee abduction moment was also decreased in the post-pubertal training group whereas it did not change in the post-pubertal control group. The program limited the development of high-risk movement patterns associated with maturation in early puberty while improving the knee mechanics in post-pubertal adolescents. Therefore, an injury prevention program should be initiated in early puberty and continue through the post-puberty years.

Abstract
OBJECTIVE To compare the epidemiology of concussion between athletes who are deaf or hard-of-hearing (D/HoH) and athletes who are hearing. DESIGN Descriptive epidemiology study. SETTING Data were collected from 2 Division III athletic programs. One institution is the world's only university designed to be barrier-free for students who are D/HoH. PARTICIPANTS Six hundred ninety-three athletes who are D/HoH and 1284 athletes who are hearing were included in this study. Athletes participated in collegiate athletics during the 2012 to 2013 through the 2016 to 2017 academic years. INTERVENTIONS Concussion data were provided by the athletic training staff at each institution. MAIN OUTCOME MEASURES Concussion counts, concussion rate, and injury rate ratios (IRRs) with 95% confidence intervals (95% CIs). RESULTS Thirty athletes who are D/HoH and 104 athletes who are hearing suffered concussions. Athletes who are hearing had an increased injury rate compared with athletes who are D/HoH for all sports combined (IRR = 1.87, 95% CI, 1.26-2.78). Football athletes who are hearing also had an increased injury rate compared with football athletes who are D/HoH (IRR = 3.30, 95% CI, 1.71-6.37). Concussion rate was higher for male athletes who are hearing than male athletes who are D/HoH (IRR = 2.84, 95% CI, 1.62-4.97). No other significant differences regarding concussion risk were identified. CONCLUSIONS Athletes who are D/HoH in sex-comparable sports may not have a higher rate of concussion than athletes who are hearing. Rate of concussion in football may be greater among athletes who are hearing compared with athletes who are D/HoH.

Abstract
BACKGROUND Shoulder injuries are common in individuals who use wheelchairs. OBJECTIVES This study investigated the presence of mechanical pain hypersensitivity and trigger points in the neck-shoulder muscles in elite wheelchair basketball players with/without shoulder pain and asymptomatic able-bodied elite basketball players. METHODS Eighteen male wheelchair basketball players with shoulder pain, 22 players without shoulder pain, and 20 able-bodied elite male basketball players were recruited. Pressure pain thresholds were assessed over C5-C6 zygapophyseal joint, deltoid muscle, and second metacarpal. Trigger points in the upper trapezius, supraspinatus, teres minor, infraspinatus, teres major, latissimus dorsi, subscapularis, pectoralis minor, pectoralis major and deltoid muscles were also examined. RESULTS Wheelchair basketball players with shoulder pain showed lower pressure pain thresholds over the C5-C6 joint and second metacarpal than elite wheelchair basketball players without pain (between-groups differences: 1.1, 95%CI 0.4, 1.8 and 1.8, 95%CI 0.8, 2.8, respectively) and able-bodied basketball players without pain (between-groups differences: 0.8, 95%CI 0.4, 1.2; 1.6, 95%CI 0.8, 2.4, respectively). The mean number of myofascial trigger points for wheelchair basketball players with unilateral shoulder pain was 4.8±2.7 (2±1 active, 2.9±2.2 latent). Wheelchair basketball players and able-bodied basketball players without shoulder pain exhibited a similar number of latent trigger points (2.4±2.0 and 2.4±1.8, respectively). Wheelchair basketball players with shoulder pain exhibited higher number of active myofascial trigger points than those without pain (either with or without wheelchair), but all groups had a similar number of latent trigger points (P<0.05). CONCLUSIONS The reported mechanical pain hypersensitivity suggests that active trigger points may play a role in the development of shoulder pain in elite male wheelchair basketball players.

Abstract
Studies that analyse the epidemiology of acute injuries in basketball players in European countries are limited. The purpose is to present an overview of the incidence of injuries and injury patterns in Flanders and to correlate them to possible intrinsic and extrinsic risk factors. All acute injuries that occurred in Flanders during 2009-2013, collected by the insurance, were analysed. The incidence and parameters such as date of birth, date of occurrence of the injury, gender and diagnosis were evaluated. Injury incidence varied from 7.40% up to 8.45%. Females and players at age 16-17, 14-15 and older than 30 are at higher risk. The ankle/foot region is most frequently injured. There is a higher risk of injury after season-and Christmas break. Age, gender and chronometry are risk factors to get injured. Sprains are the most frequent, while the nkle/foot region is the most susceptible to injury. Studies that analyse the epidemiology of acute injuries in basketball players in European countries are limited. Female players and players at age 16-17, 14-15 and older than 30 are at higher risk to basketball injuries. The ankle/foot region is most frequently injured followed by lower arm and hand. There is a higher risk of injury after season-and Christmas break.

Abstract
The aim of the study was to examine the immediate effect of 1 session of extracorporeal shockwave therapy (ESWT) on patellar tendon stiffness and to explore the relationship between the change in tendon stiffness and the pain intensity. Thirty-four male athletes aged 22.2 ± 3.8 with patellar tendinopathy were recruited. The participants were randomized into ESWT and sham groups. The ESWT group received 1500 impulses of ESWT at 4 Hz with maximal tolerable pain intensity and the sham group received intensities below 0.08 mJ/mm2. Supersonic Shearwave Imaging (SSI) was used to measure tendon shear modulus (an index of tissue stiffness), and a visual analogue scale was used to quantify the pain intensity during compression with 10 lb (4.535 kg) pressure directed on the most tender part and then during a single-leg declined-squat test. A significant reduction in tendon shear modulus (from 57.4 ± 25.5 kPa to 40.6 ± 17.6kPa, p = 0.001) was detected in the ESWT receiving ESWT with an intensity from 0.13-0.33 mJ/mm2 but not the sham group (from 47.7 ± 17.1 kPa to 41.0 ± 12.7 kPa; p = 0.06). In the ESWT group, the change in tendon shear modulus was associated with the change in the intensity of pain during single-legged declined-squat test (ρ = 0.55; p = 0.023) but not pressure pain (p > 0.05). These findings suggest that one session of ESWT induces reduction of tendon stiffness in volleyball and basketball players with patellar tendinopathy. The reduction in tendon stiffness is associated with reduction in pain during single-legged declined-squat test.

Abstract
OBJECTIVES To describe injuries associated with netball and risk factors for lower limb injuries. DESIGN Prospective study. In the preseason, risk factors were investigated using self-report questionnaires and physical measurements. During the season, injuries were reported using a standardised report, verified by follow-up phone calls. Player training and game hours were recorded. SETTING Australian community netball club. PARTICIPANTS 269 players from 9 divisions, aged 7-42 years. MAIN OUTCOME MEASURES Injury incidence rates per 1000 exposure hours were calculated. The most common mechanism, nature and consequence of injury were determined from frequencies. Logistic regression was used to identify predictors of lower limb injury and determine adjusted odds ratios for each risk factor. RESULTS 169 injuries occurred with a rate of 13.8/1000 exposure hours (95% CI 11.8-16.0), majority (60%) to the lower limb. The most frequent injury mechanisms were collisions (28%) and awkward landings (27%), nature was 'Inflammation/swelling' (32%) and consequence was 'unable to continue playing/training' (50%). Previous history of injury (OR 6.9, 95% CI 3.7-13.0) and age greater than 13.5 years (OR 3.1, 95% CI 1.6-5.9) were significant risk factors for a season lower limb injury. CONCLUSION Injury rates in this community netball club were high. Results suggest that further research regarding the implementation and effectiveness of injury prevention programs for community netballers is required.

Arthroscopy 2020; 36:473-478. [PMID: 31866277 DOI: 10.1016/j.arthro.2019.09.013] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 09/05/2019] [Accepted: 09/10/2019] [Indexed: 02/02/2023]
Abstract
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).

Abstract
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.

Abstract
CASE We present the case of a 26-year-old man who sustained a right transverse-posterior wall acetabular fracture while performing a cutting movement playing basketball. CONCLUSIONS Acetabular fracture after a relatively low-energy injury in a healthy young adult male is an extremely unusual event. The cutting movement to the right likely forcefully placed the right hip in flexion, adduction, and internal rotation directing the femoral head into the posterior wall. The patient had excellent clinical and radiographic results after acetabular open reduction and internal fixation.

Abstract
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.

Abstract
This case report presents entrapment with subsequent complete disruption of the median nerve in the distal ulna in a both-bone fracture of the forearm in a 9-year-old girl. Closed fractures of the radius and ulna commonly occur in pediatric populations. Postinjury nerve dysfunction is often seen. Severe nerve injury is rare. There are only 3 reports of the median nerve becoming entrapped in an ulnar fracture in a child, with no reports of entrapment in the distal forearm. Features seen on examination and the radiographs supported possible nerve entrapment. Although uncommon, nerve entrapment or transection should be considered in all forearm fractures with sensory or motor nerve dysfunction. If suspicions are high, an early diagnosis of nerve entrapment may be obtained with magnetic resonance imaging evaluation.

Abstract
Background and Objectives: Ankle joint is the most common site of injury for basketball athletes. An effective warm-up (WU) is a period of preparatory exercise to improve training performance and reduce sports injuries. Continuous examination of effective WU routines in basketball players is a necessity. The aim of this study was to investigate the effects of general and combined warm up on ankle injury range of motion (ROM) and balance in young female basketball players. Materials and Methods: A sample of 28 young female basketball players were randomly allocated to either global warm up control group (GWU) (n = 11) or combined warm up experimental group (CWU) (n = 17). All participants performed 7-min of run. The CWU group performed a single leg stance barefoot with eyes closed, plank forearm position and triceps sural stretching. Participants in GWU performed walking ball handling and core stability using a Swiss ball. Both WU routines were conducted 3 times per week for 10 weeks. Outcome measurements were the Stabilometric platform and dorsiflexion lunge test. Results: Twenty-eight young female basketball players completed the study. Participants in the experimental group improved significantly in the range of motion (ROM) in right and left ankle and the center of pressure displacement (CoP). The control group did not show any changes in ankle dorsiflexion and a significant reduction in all body balance parameters. Conclusions: An 8-min combined warm-up routine for 10 weeks improves the ankle dorsiflexion ROM and CoP displacement that plays a key role in ankle injuries prevention in basketball players. Further studies are strongly needed to verify our findings.

Abstract
INTRODUCTION Lateral ligamentous complex injury without fracture or dislocation is rare in the literature. Due to the rare injury, it is not clear yet about the proper treatment. This case report suggests a specific diagnosis of this injury as well as an appropriate surgical method. PATIENT CONCERNS In one-month period of time, 2 male soldiers participating in recreational basketball game presented with open wound on the lateral aspect of ankle without associated dislocation or fracture when they attempted to rebound the ball which consequently made them land on another player's foot. DIAGNOSIS Total rupture of the lateral ligament complex with open wound was found without any associated fracture or dislocation. INTERVENTIONS Open repair of the ruptured ligaments and capsule was performed. OUTCOMES Patients returned to his own job's duty with none to minimal limitation in sport and activities of daily living at 9 to 10 months after the injury. CONCLUSION Although open disruption of the lateral ligamentous complex without fracture or dislocation is rare, an adequate assessment and prompt surgical repair led to satisfactory outcome.

Abstract
CONTEXT Early sport specialization, or the participation in 1 sport year-round to the exclusion of all others, is a growing concern in youth athletics because of its possible association with musculoskeletal injury. The underlying injury risk may be the result of coordination differences that sport-specialized athletes have been speculated to exhibit relative to multisport athletes; however, little evidence exists to support or refute this notion. OBJECTIVE To examine relative hip- and knee-joint angular-motion variability among adolescent sport-specialized and multisport female adolescent athletes to determine how sport specialization may affect coordination. DESIGN Cohort study. SETTING Research laboratory. PATIENTS OR OTHER PARTICIPANTS A total of 366 sport-specialized and 366 multisport adolescent female basketball, soccer, and volleyball players. INTERVENTION(S) Drop-vertical-jump (DVJ) assessment. MAIN OUTCOME MEASURE(S) Average coupling-angle variability (CAV) for hip flexion and knee flexion, knee flexion and ankle flexion, hip flexion and knee abduction, knee flexion and knee abduction, knee flexion and knee internal rotation, and knee abduction and knee internal rotation. RESULTS The sport-specialized group exhibited increased coupling variability in dominant-limb hip flexion and knee flexion (P = .015), knee flexion and knee abduction (P = .014), and knee flexion and knee internal rotation (P = .048) while landing during the DVJ, although they had small effect sizes (η2 = 0.010, 0.010, and 0.007, respectively). No differences were present between groups for any of the other CAV measures of the dominant limb, and no differences were found for any CAV measures of the nondominant limb (all P values > .05). CONCLUSIONS Sport specialization was associated with increased variability of critical hip- and knee-joint couplings responsible for effective landing during the DVJ. Altered coordination strategies that involve the hip and knee joints may underlie unstable landings, inefficient force-absorption strategies, or greater contact forces that can place the lower extremities at risk for injury (or a combination of these).

Abstract
The primary purpose of this study was to identify potential risk factors for sports injuries in professional basketball. An observational retrospective cohort study involving a male professional basketball team, using game tracking data was conducted during three consecutive seasons. Thirty-three professional basketball players took part in this study. A total of 29 time-loss injuries were recorded during regular season games, accounting for 244 total missed games with a mean of 16.26 ± 15.21 per player and season. The tracking data included the following variables: minutes played, physiological load, physiological intensity, mechanical load, mechanical intensity, distance covered, walking maximal speed, maximal speed, sprinting maximal speed, maximal speed, average offensive speed, average defensive speed, level one acceleration, level two acceleration, level three acceleration, level four acceleration, level one deceleration, level two deceleration, level three deceleration, level four deceleration, player efficiency rating and usage percentage. The influence of demographic characteristics, tracking data and performance factors on the risk of injury was investigated using multivariate analysis with their incidence rate ratios (IRRs). Athletes with less or equal than 3 decelerations per game (IRR, 4.36; 95% CI, 1.78-10.6) and those running less or equal than 1.3 miles per game (lower workload) (IRR, 6.42 ; 95% CI, 2.52-16.3) had a higher risk of injury during games (p < 0.01 in both cases). Therefore, unloaded players have a higher risk of injury. Adequate management of training loads might be a relevant factor to reduce the likelihood of injury according to individual profiles.

Abstract
Background: Professional basketball players in the National Basketball Association (NBA) subject their lower extremities to significant repetitive loading during both regular-season and off-season training. Little is known about the incidence of lower extremity bony stress injuries and their impact on return to play and performance in these athletes. Hypothesis: Stress injuries of the lower extremity will have significant impact on performance. Study Design: Case series. Level of Evidence: Level 4. Methods: All bony stress injuries from 2005 to 2015 were identified from the NBA. Number of games missed due to injury and performance statistics were collected from 2 years prior to injury to 2 years after the injury. A linear regression analysis was performed to determine the impact of injury for players who returned to sport. Results: A total of 76 lower extremity bony stress injuries involving 75 NBA players (mean age, 25.4 ± 4.1 years) were identified. Fifty-five percent (42/76) involved the foot, and most injuries occurred during the regular season (82.9%, 63/76), with half occurring within the first 6 weeks. Among players who sustained a fifth metatarsal stress fracture, 42.9% were unable to return to professional play. Players who sustained stress injuries had reduced play performance, specifically related to number of games played (P = 0.014) and number of steals per game (P = 0.004). Players who had surgery had significantly better performance at 2 years than those who were managed nonoperatively, independent of the type of injury (β = 4.561; 95% CI, 1.255-7.868). Conclusion: Lower extremity bony stress injuries may significantly affect both short- and long-term player performance and career length. Stress injuries result in decreased player performance, and surgical intervention results in improved performance metrics compared with those treated using conservative methods. Clinical Relevance: Stress injuries result in decreased player performance, and surgical intervention results in improved performance metrics.
