Abstract
The purpose of this study was to investigate the association of stress fractures with age, sex, sport level, sporting activity, and skeletal site in athletes seen at our sports medicine clinic between September 1991 and May 2001. During these 10 years, 10 726 patients (6415 males, 3861 females) visited our clinic because of sport-related injuries, and 196 patients [125 males (1.9%), 71 females (1.8%)] sustained stress fractures. The average age of the patients with stress fractures was 20.1 years (range 10-46 years); 84 patients (42.6%) were 15-19 years of age, and 68 (34.7%) were 20-24 years of age. Altogether, 74 patients (37.8%) were active at the high recreational level and 122 (62.2%) at the competitive level. The sites of the stress fractures varied from sport to sport. The ulnar olecranon was the most common stress fracture site among baseball athletes and the rib among the rowing athletes. Classical ballet, aerobics, tennis, and volleyball athletes predominantly sustained stress fractures of the tibial shaft. Basketball athletes predominantly sustained stress fractures of the tibial shaft and medial malleolus and the metatarsal bone, whereas track and field and soccer athletes predominantly sustained stress fractures of the tibial shaft and pubic bone. Our results show that stress fractures are seen even in high-level adolescent athletes, with similar proportions for males and females, and that particular sports are associated with specific sites for stress fractures.

Abstract
The purpose of the present study was to evaluate the occurrence of oral and dental injuries in young Israeli population engaged in diverse sport activities. The participants' awareness of the use of protective devices, such as mouthguards, during sport activities was also evaluated. A population of 943 young adults, 95% males and 5% females (ages 18-19), was surveyed. A questionnaire was distributed relating to the type of sport activity practised, past oral and dental injuries over their lifetime, specifying the time and type of sports in which the injury occurred and the use and awareness of the protective devices. Of the total population examined, 850 (90%) were active in at least one type of sport, either as professionals or as amateurs. The analysis included the population that regularly participated in at least one sporting activity. The most commonly practised sports were soccer (54% of all active participants) and basketball (50%). The total number of dental and oral injuries experienced during all sport activities was 229, affecting 27% of the participants of whom 73 (9%) suffered dental injuries. Most dental injuries occurred during the basketball and soccer training sessions and matches reaching 42 and 41% of the total number of injuries, respectively, and affected 7.2 and 6.6% of the basketball and soccer players. Traumatic dental injuries in other sports occurred in less than 7% of the participants in these activities. Only 27% of the participants were aware of the protective devices, such as a mouthguards, and only 3% actually used these devices. These results point to the high risk of potential dental and oral injury during sport activities, the little knowledge about the benefits of using mouthguards and their limited utilization. The importance of public health education to increase the awareness of protective measures and devices and their actual use in Israel is the main focus. It should be a combined duty of dentists and sports physicians and of the coaches to encourage the use of protective devices during training and games.

Abstract
Basketball is a popular sport in Australia. Although orofacial injuries are common, mouthguard (MG) wear in basketball appears to be low. The purposes of this study were: to measure mouthguard wear by basketball players before and after a promotional intervention; to assess players' knowledge of the value of mouthguards for prevention of injury; and to describe their experience of orofacial injury. Two questionnaires (baseline and follow-up) were administered to a convenience sample of 496 basketball players in Victoria, Australia. Players recruited were youths (12-15-year olds, n = 208) and adults (18 years and over, n = 288), from all basketball levels (social to elite). Completion of the baseline questionnaire was followed immediately by an intervention comprising written and verbal information, a mouthguard blank and instructions on mouthguard construction. The follow-up questionnaire was mailed to all respondents 10-12 weeks later; 135 youths (65%) and 157 adults (54%) completed this. Mouthguard wear at baseline was low but was more frequent at games (62%) than at training (25%). Despite 90% of players acknowledging the protective value of a mouthguard, wear by youths did not increase following the intervention, and wear by adults increased by only 14% for training and 10% at games. Previous orofacial injury was recorded at baseline by 23% of players, but few had requested compensation from Basketball Australia (youths, 17%; adults, 30%). Two predictor variables were statistically identified as related to mouthguard wear: previous orofacial injury and age group. Mouthguard wear was significantly more frequent amongst players with previous injury; such players were 2.76 times more likely to be wearers than those without previous injury. Youths were 2.31 times more likely to wear mouthguards than adults. Only 34 players (12% of respondents at follow-up) had a mouthguard constructed from the blank provided. Although youth and adult groups differed, the overall extent of mouthguard use was disappointingly low. Despite wide recognition of mouthguard value, the intervention had little effect on promoting their use.

Abstract
Medial malleolar stress fractures are relatively uncommon injuries that can be quite debilitating and disabling. This article discusses the symptoms, diagnostic aids, pathomechanics, and management of medial malleolar stress fractures. Using three cases, the authors illustrate nonoperative versus operative treatments in an athlete and the influence of an in-season versus an off-season injury. A percutaneous cannulated screw fixation procedure is described that allowed an athlete to return to competition 24 days after sustaining a displaced medial malleolar stress fracture.

Abstract
A 16-year-old male basketball player had sustained an injury upon landing after a forceful jump. Plain radiography demonstrated bilateral tibial tubercle avulsion fracture involving partially proximal physis. Open reduction and internal fixation were performed at once. Continuous passive motion was started immediately after operation, and the patient was ambulated with hinged knee extension braces. After 27 months follow-up his knees completely regained normal range of motion except a 3 degrees extension loss in the left knee. He resumed all daily functional activities (Lysholm functional score of 99), but he slightly lost his level of activity (Tegner activity level from 7 to 6). No angular deformity at all on the frontal plane was determined upon radiological examination. Tibial slope angles were symmetrical and within the normal range. There were visible small bone fragments inside the left patellar tendon.

Abstract
BACKGROUND Previous studies of basketball injury have not been able to assess injury incidence and risk. PURPOSE To determine rates and risks of injury in Canadian intercollegiate basketball. STUDY DESIGN Prospective cohort study. METHODS Standardized data were collected with a validated instrument from 98.1% of the 318 athletes on the eight men's basketball teams in the Canada West Division of the Canadian Intercollegiate Athletic Union. RESULTS A total of 142 athletes sustained 215 injuries (44.7% of players injured) over the 2-year study period. The greatest number of injuries resulting in more than seven sessions of time loss involved the knee, whereas the most common injuries causing fewer than seven sessions of time loss involved the ankle. The most common mechanism of injury was contact with another player, especially in the "key." Injuries occurred 3.7 times more often in games than during practice. Centers had the highest rate of injury, followed by guards, and then forwards. The relative risk of reinjury was significantly increased by previous injuries to the elbow, shoulder, knee, hand, lower spine or pelvis, and by concussions. CONCLUSIONS Risk factors for injury were previous injury, games as opposed to practice, player position, player contact, and court location.

Abstract
OBJECTIVE The purpose of this epidemiologic study is twofold: first, to determine the relative frequency of sports-related injuries compared with all musculoskeletal injuries in patients 5 to 21 years of age presenting to the emergency department (ED), and second, to evaluate the sports-specific and anatomic site-specific nature of these injuries. METHODS Patterns of injury in patients 5 to 21 years of age presenting to four pediatric EDs with musculoskeletal injuries in October 1999 and April 2000 were prospectively studied. Information collected included age, sex, injury type, anatomical injury site, and cause of injury (sports-related or otherwise). Information about patient outcome and disposition was also obtained. RESULTS There were a total of 1421 injuries in 1275 patients. Musculoskeletal injuries were more common in male patients (790/62%) than in female patients. The mean age of the patients was 12.2 years (95% CI, 12.0-12.4). Sprains, contusions, and fractures were the most common injury types (34, 30, and 25%, respectively). Female patients experienced a greater percentage of sprains (44% vs 36%) and contusions (37% vs 33%) and fewer fractures (22% vs 31%) than male patients. Sports injuries accounted for 41% (521) of all musculoskeletal injuries and were responsible for 8% (495/6173) of all ED visits. Head, forearm, and wrist injuries were most commonly seen in biking, hand injuries in football and basketball, knee injuries in soccer, and ankle and foot injuries in basketball. CONCLUSIONS Sports injuries in children and adolescents were by far the most common cause of musculoskeletal injuries treated in the ED, accounting for 41% of all musculoskeletal injuries. This represents the highest percentage of sports-related musculoskeletal injuries per ED visit reported in children to date. As children and adolescents participate in sports in record numbers nationwide, sports injury research and prevention will become increasingly more important.

Abstract
PURPOSE Females have a disproportionately high incidence of anterior cruciate ligament (ACL) injuries compared with males in analogous sports. Although the pathogenesis of this higher frequency has not been elucidated, gender differences in neuromuscular control of the knee may play an important role. This study evaluates EMG power spectra of the quadriceps and hamstring muscles during dynamic, fatiguing exercise to examine differences between male and female intercollegiate athletes. METHODS Fifty-one collegiate basketball and soccer players (25 female, 26 male) were studied. Maximum voluntary contraction (MVC) was determined for knee flexion and extension. Three consecutive 2-min bouts of isokinetic knee flexion and extension exercise were performed at 40% MVC. EMG activity in the biceps femoris and vastus medialis obliquus was recorded using bipolar surface electrodes. RESULTS MVC normalized to body weight was significantly greater in males than in females for the quadriceps (P< 0.01). Quadriceps coactivation ratios were significantly higher in females than in males during knee flexion exercises (P< 0.01). CONCLUSIONS This study demonstrates differences in the EMG power spectra for females when compared with a matched group of males. Increased quadriceps coactivation in females may increase anterior tibial loads under dynamic conditions, thus placing the ACL at higher risk for injury in the female athlete.

Abstract
Bipartite patella fracture is an uncommon injury that has rarely been described in the literature. It can be quite debilitating in the competitive athlete and is often overlooked by the treating physician. A bone scan can be helpful in confirming the diagnosis, and appropriate treatment often results in a successful outcome.

Abstract
Multiple factors are responsible for ACL tears. The key factor in the gender discrepancy appears to be dynamic, not static, and proximal, not distal. The factors involved in evaluating the female ACL are multiple. However, it is the dynamic movement patterns ot hip and knee position with increased flexion and a coordinated proximal muscle firing pattern to keep the body in a safe landing position that are the most critical factors. An ACL injury at an early age is a life-changing event. We can very successfully reconstruct and rehabilitate an ACL, but we cannot stop there. We must now go into the prevention arena. In the United States there is tremendous variation in the exposure and acquisition of skills of physical activities in our youth. Today, children are often playing inside, using computers and watching television-missing out on the opportunity to learn safe movement patterns. Therefore, physical movement classes should occur very early in life, teaching children to land safely and in control, similar to the cry of "get down, stay down" routinely heard during youth soccer. Similarly, specific strength training programs can address landing as well as foot movements during cutting in basketball. Coaches should issue stern warnings when athletes demonstrate a high-risk movement patterns such as one-leg landings, out-of-control baseline landings, or straight-leg landings. The warnings may serve to keep the athlete from "touching the hot stove again" for fear of getting burned. No athlete feels she will be the one to get injured. Therefore, prospective analysis is likely to be received more warmly by the athletes if the program is presented with an emphasis on performance improvement rather than injury prevention. With increased participation in these programs, multiple-center analysis will have the power necessary to determine which factors significantly predispose athletes to ACL injury. The future for injury prevention is bright. We must rise to the challenge.

Abstract
OBJECTIVE The purpose of our study was to evaluate the knees of asymptomatic high-level collegiate basketball players before the beginning of the basketball season to gain an understanding of nonclinical findings in this patient population. SUBJECTS AND METHODS Bilateral knee MR imaging examinations of 17 varsity basketball players (12 men and five women) were performed before basketball season began. All of the subjects were imaged on a 1.5-T magnet. The MR imaging studies were reviewed by two musculoskeletal radiologists. Structures analyzed were the menisci, ligaments, cartilage, plicae, and bone marrow. The presence of a joint effusion was also noted. RESULTS Fourteen (41%) of the 34 knees had bone marrow edema, eight (24%) showed signal in the patellar tendon, and 14 (41%) had abnormal cartilage signal or a focal abnormality. Twelve (35%) of the 34 knees showed a joint effusion. Two knees (6%) showed abnormal signal along the infrapatellar plica. Four knees (12%) were noted to have a discoid meniscus. CONCLUSION An MR examination of the knees of high-level collegiate basketball players may show changes unique to this population. The changes seen on MR imaging in these athletes may be asymptomatic abnormalities. For instance, changes suggestive of patellar tendinopathy were identified in these asymptomatic subjects.

Abstract
We retrospectively reviewed 13 patellar tendon repairs done over 32 months at a tertiary care, military medical center. Early mobilization was initiated within 2 weeks postoperatively. Clinical and functional results were statistically examined with relation to age, timing of surgery, length of follow-up, quadriceps atrophy, extensor lag, patella position, and time to full duty. At an average of 24 months' follow-up, six patients (46%) had thigh girth atrophy, and one patient (8%) had an extensor lag >5 degrees. Mean Lysholm score was 84 (range, 57 to 100). Maximum postoperative Tegner activity scores averaged 7.1 (range, 5 to 10). Clinical results classified five cases as excellent, three good, three fair, and two poor. Functional results classified three cases as excellent, four good, two fair, and four poor. Time to return to duty averaged 13 months. Our results suggest that adequate extensor function can be restored after primary repair and immediate motion therapy.

Abstract
We present two rare cases of volar and dorsal fractures of the middle phalanx at the proximal interphalangeal joint (PIPJ). The first case was a 16-year-old girl. She hurt her middle finger while playing basketball. A lateral radiograph revealed volar and dorsal fractures of the middle phalanx. She underwent external immobilization of the PIPJ in 30 degrees of flexion with a splint for 3 weeks. The fractures healed 7 weeks after the injury with neither tenderness nor limitation of range of motion. The second case was a 16-year-old boy. He injured his index finger while playing basketball, and underwent immobilization of the PIPJ for 3 weeks. At 10 weeks after the injury, the dorsal fracture was almost healed, but the displacement of the volar fragment had worsened. At a 3-year follow-up, the dorsal fragment was healed, but the volar fragment remained in a site of nonunion. However, there was neither residual deformity nor restriction of movement.

Abstract
The objective of the present work was to study the occurrence of dental trauma in different sports, as well as to check if athletes used mouthguard during sport activities, and knew the significance of its utilization. The professional and semi-professional athletes who practised contact sports were interviewed, and were analyzed to determine the occurrence of dental trauma during sport practice, as well as if the athletes used a mouthguard and knew its indication. Results showed a high rate of dental trauma in athletes compared to the general population. The majority of athletes also demonstrated little utilization of mouthguard, in spite of the information about usage during sports practices and a general knowledge of its uses.

Abstract
Subtle changes in patellofemoral joint biomechanics may influence lower extremity function. The McConnell method of patellar taping has become an increasingly popular method of managing patients with various patellofemoral joint disorders. The purpose of this order effect controlled study was to assess medial patellar taping (McConnell Method) for changes in peak plantar force location and timing while running and dribbling a basketball prior to the performance of a basketball lay-up. Sixteen non-impaired, right hand dominant members of a female junior varsity basketball team (age=14.6 +/- 2 years) participated in this study. Subject bodyweight and height were 607.8 +/- 99 N and 1.67 +/- 0.10 m, respectively. All data were collected from the preferred stance limb. A series of two way analysis of variance (ANOVA) (condition, trial) were used to determine statistical significance (P < or = 0.05). During medial patellar taping, subjects displayed a more forefoot directed peak plantar force location 89.9 +/- 18 versus 81.3 +/- 21 mm and delayed peak plantar force onset 141 +/ - 23 versus 130 +/- 29 ms following initial ground contact. Medial-lateral peak plantar force location and peak plantar force magnitude did not differ between conditions, however, medial-lateral peak plantar force location displayed significant trial sequence influences with the latter trials displaying more lateral center of plantar force locations (30.4 +/- 2 vs. 32.5 +/- 3 mm). The results of this study suggest that medial patellar taping influences distal lower extremity function by shifting peak plantar force location toward the forefoot, and delaying its onset. These changes with consideration for known synergistic ankle plantar flexor-subtalar joint invertor and knee extensor function during weight bearing suggest the presence of increased muscular stiffness acting through a more rigid foot to improve the impact force attenuating capability of the lower extremity.

Abstract
We report a case of severed sutures of the tibial bone peg during anterior cruciate ligament reconstruction. The graft retracted proximally in the bone tunnel. We describe a simple and aesthetically acceptable method to salvage this rare complication by use of a small arthrotomy through the defect in the remaining patellar tendon.

Abstract
PURPOSE Dental injuries can be permanent and disfiguring. They are also universally expensive to treat. Many dentists, sports physicians, and athletic trainers recommend mouthguards for athletes participating in certain competitive sports, including men's college basketball, because of a common perception that mouthguards afford protection from dental injuries, and even some concussions. However, there are few reliable reports of the incidence of dental injuries and concussions in men's college basketball, and good evidence that mouthguards reduce the risk of these injuries in this population of athletes is notably lacking. This study prospectively recorded dental injuries and concussions among 50 men's Division I college basketball teams during one competitive season, then compared injury rates between mouthguard users and nonusers. METHODS During the 1999 to 2000 basketball season, athletic trainers from 50 men's Division I college basketball programs used an Internet Web site to submit weekly reports of the number of athlete exposures, mouthguard users, concussions, oral soft tissue injuries, dental injuries, and dentist referrals. RESULTS Response rate was 86%. There were 70,936 athlete exposures. Athletes using custom-fitted mouthguards accounted for 8663 exposures. Injury rates were expressed as number of injuries per 1000 athlete exposures. There were no significant differences between mouthguard users and nonusers in rates of concussions (0.35 vs 0.55) or oral soft tissue injuries (0.69 vs 1.06). Mouthguard users had significantly lower rates of dental injuries (0.12 vs 0.67; P < 0.05) and dentist referrals (0.00 vs 0.72; P < 0.05) than nonusers. CONCLUSION Custom-fitted mouthguards do not significantly affect rates of concussions or oral soft tissue injuries, but can significantly reduce the morbidity and expense resulting from dental injuries in men's Division I college basketball.

Abstract
OBJECTIVES This paper examines the literature dealing with oral-facial injuries received during participation in sport and the possibilities open to athletes for their prevention. In particular, the paper examines five different aspects of this topic: the risk of dental injury while playing sports, the role of the mouthguard in preventing injury, types of athletic mouthguard, implications for patients undergoing orthodontic treatment and behavioural aspects of mouthguard wear. RESULTS It is clear from this review that participation in a number of sports does carry a considerable risk of sustaining dental injury, not only in the so-called contact sports such as rugby and hockey, but also in less obviously dangerous sports such as basketball. Although some evidence exists to the contrary, the majority of studies have found the mouthguard to be the most effective way of preventing such injuries. It is also clear that the custom-fabricated mouthguard, in particular the pressure-laminated variety, is seen to afford most protection. Athletes undergoing orthodontic treatment present a particular problem as they are potentially at greater risk of injury because of increased tooth mobility and the presence of orthodontic appliances. The fabrication of mouthguards for these patients is also problematic and the literature covering this is reviewed. As with other preventive measures, mouthguard usage is often less than the dental profession would like; the reasons for this are explored in a small number of studies. CONCLUSION While much progress has been made in this area, the profession could do much more to promote the greater use of mouthguards.

Abstract
Arthroscopy has helped greatly in understanding the nature of many intra-articular disorders of the hip. It also has provided a better understanding of the pathomechanics and natural progression. This knowledge has aided in improving interpretative clinical skills and investigative techniques. Isolated traumatic chondral injury can occur as a result of impact loading over the greater trochanter. There seems to be a particular propensity for this injury in young physically fit adult males apt to incur this type of blow as a consequence of sport or activity. Initially, this injury may appear innocuous with variable dysfunction. When present, arthroscopy can reliably discern the pathology and often result in significant symptomatic improvement. The long-term consequences of these lesions are still concerning. Although symptomatic improvement from arthroscopic intervention is encouraging, for some cases the long-term influence may only be the knowledge provided for counseling the patient. Nonetheless, arthroscopy can be valuable in both the assessment and management of chondral injuries.

Abstract
The lateral notch is a radiographic sign that describes a depression in the lateral femoral condyle near the terminal sulcus. The sign was first described in association with chronic instability in an anterior cruciate ligament-deficient knee. Recently, the senior author, after a prospective study, reported that these lateral notches might occur acutely at the time of anterior cruciate ligament injury. We report such a case in which the lateral femoral condylar depression fracture resulted in symptoms of lateral compartment incongruity. Open reduction and internal fixation were required. Anterior cruciate ligament reconstruction was performed as a staged procedure 2 months after fracture reduction. The postoperative result has been excellent for over 5 years. This case is an example that lateral femoral notches may be acute and a source of symptoms. In some cases, reduction and fixation of significant depressions in association with ligament reconstruction can alleviate these symptoms and may improve the patient's long-term result.

Abstract
Three case studies of fractures are presented that demonstrate the potential morbidity that these injuries can cause as well as the acceptable outcomes if treated appropriately. Two of the cases are talar fracture dislocations; the third is an osteochondral fracture of the talus. The importance of early treatment with open reduction and internal fixation is demonstrated. Success following surgical intervention in a nonhealed osteochondral fracture of the talus is also demonstrated.

Abstract
STUDY DESIGN Case study. OBJECTIVE To compare knee kinematics and moments of nongiving way trials to a giving way trial during a combined stepping and crossover cutting activity. BACKGROUND The knee kinematics and moments associated with giving way episodes suggest motor control strategies that lead to instability and recovery of stability during movement. METHODS AND MEASURES A 27-year-old woman with anterior cruciate ligament deficiency reported giving way while performing a combined stepping and crossover cutting activity. A motion analysis system recorded motion of the pelvis, femur, tibia, and foot using 3 infrared emitting diodes placed on each segment at 60 Hz. Force plate recordings at 300 Hz were combined with limb inertial properties and position data to estimate net knee joint moments. The stance time, foot progression angle, and cutting angle were also included to evaluate performance between trials. RESULTS Knee internal rotation during the giving way trial increased 3.2 degrees at 54% of stance relative to the nongiving way trials. Knee flexion during the giving way trial increased to 33.1 degrees at 66% of stance, and the knee moment switched from a nominal flexor moment to a knee extensor moment at 64% of stance. The knee abductor moment and external rotation moment during the giving way trial deviated in early stance. CONCLUSIONS The observed response to the giving way event suggests that increasing knee flexion may enhance knee stability for this subject. The transverse and frontal plane moments appear important in contributing to the giving way event. Further research that assists clinicians in understanding how interventions can impact control of movements in these planes is necessary.

Abstract
Low back pain is a common finding in an athletically active premenopausal female population. We describe an unusual cause of persistent low back/sacroiliac pain: a fatigue-type sacral stress fracture. Plain radiographs, bone scans, computed tomography, and magnetic resonance imaging studies were obtained in the female athletes to determine the nature of the pathologic abnormality. The most significant risk factor for fatigue-type sacral stress fractures was an increase in impact activity due to a more vigorous exercise program. Potential risk factors such as abnormal menstrual history, dietary deficiencies, and low bone mineral density were examined. The clinical course was protracted, with an average 6.6 months of prolonged low back pain before resolution of symptoms. Sacral fatigue-type stress fractures did not preclude the athletes from returning to their previous level of participation once healing had occurred.

Abstract
OBJECTIVE to examine a group of high risk athletes, for signs of inflammation in jumper's knee (JK) by gray-scale ultrasonography (US) and color/Power Doppler findings in JK. SUBJECTS AND METHODS eighteen high-elite basketball players participated in the investigation after a match. Seven players were examined by ultrasound before the match as well. The players were clinically examined for signs of JK and filled in a questionnaire concerning previous and present knee symptoms. RESULTS clinical signs of JK were found in 13 knees. Of these knees, ten had hypoechoic areas and six had Power Doppler flow. Four players reported symptoms of JK and clinical examination suspected the same. Three of them had both hypoechoic areas and Power Doppler flow. Fourteen players were asymptomatic at the time of examination but both hypoechoic areas and Power Doppler flow was found in the patellar tendons of four players. No correlation was found between clinical findings, symptoms of JK and US findings - including Power Doppler. The risk of type II error in this material is considerable. CONCLUSION an association between gray-scale US and color/Power Doppler was found in JK which may suggest an inflammatory component to be a part of the pathogenesis of JK.

Abstract
PURPOSE Recent studies have shown that female athletes suffer a higher incidence of anterior cruciate ligament (ACL) tears than comparable male athletes. The purpose of this study was to evaluate the effect gender has on outcome in ACL reconstruction using bone-patellar tendon-bone autograft. TYPE OF STUDY Retrospective case review and outcome study. METHODS A retrospective review of a single surgeon's practice revealed 279 ACL reconstructions that met our criteria for inclusion. Two-hundred forty-nine of these patients (91%) were contacted. Two-hundred (72%) were evaluated with physical examination, KT-1000 testing, functional testing, and radiographic evaluation. Outcome was assessed with Tegner, Lysholm, modified HSS, and Cincinnati Knee rating scales, as well as the SF-36 health survey and a self-administered questionnaire. There were 137 men and 63 women. Data were evaluated with Wilcoxon rank sum testing, analysis of variance testing, chi-square analysis, and the Student t test. The level of significance was set at P <.05. RESULTS Postoperatively, no differences were noted on Lachman, anterior drawer, pivot shift, or functional testing in either groups. Male patients had a significantly greater mean prone heel height difference (1.80 v 1.10 cm, P =.0018) and mean KT-1000 maximum manual side-to-side difference (0.76 v 1.73 mm, P =.014). However, no differences were noted in the percentage of patients with greater than 5-mm side-to-side difference, with 5 men (4%) and 2 women (3%) classified as arthrometric failures. No differences were noted in mean Tegner, Lysholm, Noyes Cincinnati, and modified HSS scores. Men had significantly lower HSS radiographic scores (24.98 v 26.22, P =.0016). Men and women were compared with gender-matched controls for SF-36 testing, and women scored higher compared with controls than did men in the Role Physical, Body Pain, and General Health categories. No differences were noted in either group regarding donor-site pain, patellofemoral crepitance, or problems with stair climbing. Ninety-six percent of men and 98% of women would have had the surgery over again given similar circumstances. CONCLUSIONS Objective criteria failed to detect clinically significant differences in physical examination and arthrometric results between men and women. Knee rating scale scores were similar. Comparable outcome with high satisfaction and equal success can be expected in both men and women undergoing ACL reconstruction using bone-patellar tendon-bone autograft. No basis exists for the inclusion of gender as a determining factor regarding the decision to perform ACL reconstructive surgery with bone-patellar tendon-bone autograft.

Abstract
The study aimed to determine prospectively a basketball injury profile, including severity of injury, and to compare the injury profile by gender and standard of competition. Trained observers viewed basketball games, noting the occurrence of injuries, and confirmed injuries by questioning all players on site after the game. Injured players completed a questionnaire and the progress of their injury was monitored by telephone interview. A total of 10,393 basketball participations were observed. An overall injury rate was documented of 18.3 per 1,000 participations (24.7 per 1,000 playing hours), and was comparable by gender and standard of competition. Serious injuries (missing one or more weeks of play) occurred at a rate of 2.89/1,000 participations; with the ankle joint the most common serious injury (1.25/1,000 participations), followed by the calf/anterior leg (0.48/1,000 participations) and knee joint (0.29/1,000 participations). The severity of the injury was significantly associated with the body region injured, with more serious injuries incurred to the lower limb than other body regions (p <.05). The severity of the injury incurred was not related to the standard of competition, gender, age, height, number of games played per week, amount of training undertaken, type of injury, or the mechanism of injury (p> .05).
