Long-term outcome of knee and ankle injuries in elite football.

To estimate the risk and evaluate the long-term outcome of knee and ankle injuries in former national team elite football, 69 players were randomly selected, followed by clinical and stress radiographic examinations. Thirty-nine players (49 knees) had had knee injuries and 29 ankle injuries (35 ankles). The median time from injury until study examination was 25 years. The knee injuries were tears of the medial collateral ligament (MCL) in 24 cases combined with rupture of the anterior cruciate ligament (ACL) and meniscus lesions in three. Meniscus lesions had occurred in 17 cases including three combined with ACL and MCL and another two with ACL ruptures. Isolated rupture of the ACL had occurred in four cases. The ankle lesions were in 26 of 35 cases ruptures of the lateral ligaments. In all, 12 players had completely stopped football and three had changed occupation. Signs of arthritis were present in 63% of the injured knees and in 33% of the injured ankles. The incidence of arthritis in the group of 17 uninjured players was 26% in the knee and 18% the ankle. In elite football players knee and ankle injuries seem to have a serious long-term outcome, but also uninjured players have a higher risk of developing arthritis than the normal population.

Ankle injuries in basketball players.

We carried out a retrospective study of the frequency of ankle sprains in basketball players. A questionnaire about previous ankle injuries, time off after such injuries, current ankle problems, personal data, number of practice hours and the use of prophylactic measures was sent out to 102 basketball players in a second division league in Sweden. Ninety-six players answered. 92% of them had suffered an ankle sprain while playing basketball, and of these 83% reported repeated sprains of one ankle. In the last two seasons, 78% of the players had injured at least one ankle. The injury frequency in the investigation was 5.5 ankle injuries per 1000 activity hours. 22% of the players used some kind of prophylactic support of their ankle joints. Because of the great number of ankle sprains and the disability in terms of time away from sports that they cause, prevention of these injuries is essential.

The role of fibular tape in the prevention of ankle injury in basketball: A pilot study.

STUDY DESIGN: Prospective nonrandomized controlled trial. OBJECTIVES: To determine the effect of fibular repositioning tape (FRT) on incidence and severity of ankle injury. BACKGROUND: Pain and functional disability is common following ankle sprain and a major problem in sport. A novel method of taping, FRT, which has been described to prevent ankle sprain, requires less tape than traditional methods and is easier to apply. The objective of this study was to determine the effect of FRT on the incidence and severity of ankle injury in basketball. METHODS AND MEASURES: One hundred twenty-five male basketball players were assigned at time of play to either the control (209 exposures) or FRT (224 exposures) condition in a manner of convenience. Control participants had the choice on the use and type of prophylaxis, excluding FRT. FRT participants were taped using the method described by Mulligan. Ankle injury data were collected after each exposure. Injury severity was determined by functional limitation, pain levels, and days to return to play. RESULTS: Four hundred forty-three measured basketball exposures resulted in 11 ankle injuries. All injuries occurred in subjects with a history of previous ankle sprain. Significantly less ankle injuries were sustained by members of the FRT condition (n = 2), compared to members of the control condition (n = 9) (Fisher exact test, P = .03). The odds ratio of sustaining an ankle injury was 0.20 (P = .04; 95% confidence interval [CI]: 0.04, 0.93) when taped with FRT and the number needed to treat was 22 (95% CI, 12-312). CONCLUSIONS: This study provides preliminary data regarding the prophylactic effects of FRT on ankle injury in male basketball players.

The efficacy of a semirigid ankle stabilizer to reduce acute ankle injuries in basketball. A randomized clinical study at West Point.

This randomized clinical study was designed to prospectively determine the efficacy of a semirigid ankle stabilizer in reducing the frequency and severity of acute ankle injuries in basketball. Athletic shoe, playing surface, athlete-exposure, ankle injury history, and brace assignment were either statistically or experimentally controlled. Participants in the study were 1601 United States Military Academy cadets with no preparticipation, clinical, functional, or radiographic evidence of ankle instability. Subjects experienced a total of 13,430 athlete-exposures in the 1990 and 1991 intramural basketball seasons. Ankle injury was defined as acute trauma to the ankle ligaments that resulted in an athlete's inability to participate in basketball 1 day after the injury. Use of ankle stabilizers significantly reduced the frequency of ankle injuries. Reduction in ankle injuries, however, depended on the nature of injury (fewer contact injuries occurred among those who wore braces). Injury severity was not statistically reduced, and wearing the ankle stabilizer did not affect the frequency of knee injuries. Attitude toward ankle stabilizer use improved as use of the stabilizer increased.

Radiographic evaluation of foot and ankle injuries in the athlete.

Injuries of the ankle and foot in athletes are quite common. They range from the extremely simple sprain to the difficult stress fracture, and may result in long-term disability. In all cases, the athlete is best treated after an accurate diagnosis is achieved.

The relevance of hearing a crack in ankle injuries.

OBJECTIVE: To examine the predictive value of a crack noise or sensation in the history of injury in the diagnosis of ankle fracture. METHODS: A short questionnaire was filled in on 464 patients with isolated ankle injuries attending the accident and emergency department in a three month period from July to September. These patients were seen in the usual way in the department and the need for x ray assessed according to clinical judgement and existing departmental guidelines. Cases which subsequently proved to be other than ankle injuries, for example, fractured calcaneus, were excluded from the study. RESULTS: A positive history of hearing or feeling a crack did not indicate the need for an x ray or increase the possibility of a fracture; indeed the history of a crack made the presence of a fracture less likely. The clinical diagnosis of absence of fracture without radiological examination may require careful explanation to the patient. CONCLUSIONS: Hearing a crack in the ankle does not suggest a fracture.

Rehabilitation of foot and ankle injuries.

Rehabilitation of foot and ankle injuries is essential for full functional recovery and prevention of chronic disease. Rehabilitation includes the usage of physical therapy modalities and rehabilitative exercise whose goals are the reduction of pain and edema and the increase of strength and proprioception. Physical therapy modalities may be classified as thermal, mechanical or electrical agents and include the use of ice, heat, ultrasound, phonophoresis, iontophoresis, intermittent compression, therapeutic massage and a variety of electrical currents. Rehabilitative exercises are primarily designed to increase flexibility, range of motion, strength, proprioception and sport-specific development prior to resumption of full activity. Proper rehabilitation of the lateral ankle (inversion) sprain is critical due to its frequency and potential for chronic pain and recurrence.

Effectiveness of an outside-the-boot ankle brace in reducing parachuting related ankle injuries.

OBJECTIVES: To examine the efficacy of an outside-the-boot parachute ankle brace (PAB) in reducing risk of ankle injury to army paratrooper trainees and to identify inadvertent risks associated with PAB use. DESIGN: The authors compared hospitalization rates for ankle, musculoskeletal, and other traumatic injury among 223,172 soldiers trained 1985-2002 in time periods defined by presence/absence of PAB use protocols. Multiple logistic regression analysis estimated adjusted odds ratios (OR) and 95% confidence intervals for injury outcomes, comparing pre and post brace periods to the brace protocol period. SETTING: A research database consisting of training rosters from the US Army Airborne training facility (Fort Benning, GA) occupational, demographic, and hospitalization information. MAIN OUTCOME MEASURES: Injuries were considered training related if they occurred during a five week period starting with first scheduled static line parachute jump and a parachuting cause of injury code appeared in the hospital record. RESULTS: Of 939 parachuting related hospitalizations during the defined risk period, 597 (63.6%) included an ankle injury diagnosis, 198 (21.1%) listed a musculoskeletal (non-ankle) injury, and 69 (7.3%) cited injuries to multiple body parts. Risk of ankle injury hospitalization was higher during both pre-brace (adjusted OR 2.38, 95% CI 1.92 to 2.95) and post-brace (adjusted OR 1.72, 95% CI 1.27 to 2.32) periods compared with the brace protocol period. Odds of musculoskeletal (non-ankle) injury or injury to multiple body parts did not change between the brace and post-brace periods. CONCLUSION: Use of a PAB during airborne training appears to reduce risk of ankle injury without increasing risk of other types of traumatic injury.

Diagnosis of ankle injuries: the essentials.

Ankle fractures following trauma may be suspected by the astute clinician. However, major disability can result from inappropriate treatment caused by unrecognized soft tissue pathology. The author reviews ankle joint anatomy and mechanisms of injury in an attempt to define the relationships between soft tissue and osseous trauma to that region.

Management of severe open ankle injuries.

BACKGROUND: Functional outcome after reconstruction of open ankle injuries has not been well presented in the literature. The authors present the functional results of 24 patients who sustained complex ankle injuries. METHODS: Patients were assessed using three scoring systems (a modified A/O score, the Enneking score, and the AOFAS) and subdivided into two groups: those primarily treated at Charing Cross Hospital according to strict protocols combining orthopedic and plastic surgical techniques (group P) and those secondarily treated who were transferred to Charing Cross Hospital after initial management at a remote unit (group S). RESULTS: There were nine patients (37.5 percent) in group P and 15 (62.5 percent) in group S. Eighteen patients (75 percent) underwent free-tissue transfer. Sixteen patients (67 percent) were assessed (group P, n = 7; group S, n = 9) for return of function using the Enneking score. Mean time to assessment was 10.5 months for group P and 11.4 months for group S. Mean Enneking percentage score was 75 for group P and 72.2 for group S. There were no significant differences (p > 0.05) between these scores. The mean time to union was 19 weeks (n = 5) for group P and 24 weeks (n = 7) for group S. The mean AOFAS Ankle-Hindfoot Scores were comparable to the Enneking scores when independent observers undertook this assessment. Most patients in both groups reported difficulty with descent of stairs. CONCLUSIONS: Although the authors were able to achieve a similar return of function for both groups, group S patients needed at least one more operation. In cases of ankle fracture where there is significant soft-tissue injury (either closed or open), representing a complex injury, the authors recommend making no attempt to internally fix the fracture and instead referring the patient to a specialist center for combined orthoplastic attention. If this is not immediately at hand, screw fixation of the medial malleolus should be undertaken after open reduction. The lateral malleolus should not be internally fixed, but should it require control, external fixation is the preferred method of skeletal stabilization.

Use of radiography in acute ankle injuries: physicians' attitudes and practice.

OBJECTIVES: To examine the efficiency of the current use of radiography in patients with acute ankle injury. To study the judgements and attitudes of experienced clinicians in their use of ankle radiography and to thereby assess the potential for improved efficiency. DESIGN: Two-stage study: retrospective chart review and prospective survey. SETTING: Emergency departments of two adult teaching hospitals and one community hospital. PARTICIPANTS: The records of 1831 adults presenting with acute blunt trauma to the ankle over 5 months were examined; another 732 patients were seen by 21 full-time emergency staff physicians over a subsequent 6-month period. MEASURES AND MAIN RESULTS: Of the 1831 patients with an ankle injury in stage 1, 94.9% had had at least one radiographic series; the yield for clinically important fractures was 12.8%. In stage 2, experienced physicians predicted the probability of fracture to be 0% or 10% in 57.8% of cases. The kappa (kappa) level for interobserver agreement in 98 patients seen independently by two physicians was 0.55 (95% confidence interval [CI] 0.39 to 0.72). The area under the receiver operating characteristic curve for physicians' predicted probability was 0.88 (95% CI 0.84 to 0.92), reflecting good discrimination between fracture and nonfracture cases. Likelihood ratios for predicted probabilities ranged from 0.08 for the 0% level to 151 for the 100% level. The physicians indicated that they would feel comfortable or very comfortable in not ordering radiography in 45.9% of cases (kappa level 0.52; 95% CI 0.34 to 0.70). CONCLUSIONS: Emergency physicians order radiography for most patients with ankle injury even though they can accurately discriminate between fracture and nonfracture cases and clearly expect most of the radiographs to give normal results. These findings suggest great potential for a more efficient use of radiography in patients with ankle injury, possibly through the use of guidelines.

Ultrasound examination of ankle injuries in children.

Fourteen children with ankle injuries, an open tibia and fibula physis, and negative radiographs had ultrasonography of their injured ankles. Five had an anterior talofibular ligament injury and five had an anterior tibiofibular ligament injury. Four had normal ultrasound examinations. Only two had a physeal injury, both of which were associated with a ligament injury. Eleven children had only lateral ankle tenderness. Ultrasound of these 11 revealed ligamentous injuries, normal examinations, and the two physeal injuries. Ligamentous injury was not associated with other tenderness patterns.

Acute ankle injury and chronic lateral instability in the athlete.

Ankle injuries occur frequently in sports. The lateral ligamentous complex, specifically the anterior talofibular and calcaneofibular ligaments, are most commonly injured. In acute lateral ligament injuries, a functional ankle rehabilitation program is the mainstay of treatment. Chronic ankle instability develops in a minority of patients. Surgical procedures are broadly classified into anatomic ligament repairs versus reconstructive tenodeses. Commonly performed techniques include the Brostrom-Gould procedure,the modified Brostrum-Evans procedure, and the Chrisman-Snook procedure.

Balance as a predictor of ankle injuries in high school basketball players.

OBJECTIVE: The purpose of this study was to determine if a preseason measurement of balance while in a unilateral stance could predict susceptibility to ankle injury in a cohort of high school basketball players. Predicting risk for ankle injury could be important in helping to reduce the risk of these injuries and furthermore save health care costs. DESIGN: Cohort study. SETTING: Data were collected at five high schools during the first 2 weeks of the 1997-1998 and 1998-1999 basketball seasons. SUBJECTS: 210 (119 male, age = 16.1 +/- 1.1 yr; height = 182.98 +/- 7.4 cm; weight = 76.4 +/- 10.9 kg; and 91 female, age = 16.3 +/- 1.3 yr; height = 170.9 +/- 7.8 cm; weight = 63.4 +/- 8.4 kg) high school basketball players who did not sustain a time loss ankle or knee injury within the previous 12 months served as subjects. Subjects did not use prophylactic ankle taping or bracing during the season. ASSESSMENT OF RISK FACTORS: Balance was quantified from postural sway scores measured while subjects performed unilateral balance tests with eyes both open and closed. Logistic regression analysis was carried out to determine if gender, dominant leg, and balance scores were related to ankle sprain injuries. In addition, Fischer's exact test was used to determine if the rate of ankle injuries was the same whether the subject had poor, average, or good balance. Balance was assessed by measuring postural sway with the NeuroCom New Balance Master version 6.0 (NeuroCom International, Clackamas, OR, U.S.A.). Testing to determine postural sway consisted of having subjects stand on one leg for three trials of 10 seconds with their eyes open, then repeated with their eyes closed. Subjects then underwent the same assessment while standing on the other leg. Postural sway was defined as the average degrees of sway per second (degrees S/S) for the 12 trials producing a compilation (COMP) score. OUTCOME MEASURES: Ankle injury resulting in missed participation. RESULTS: Subjects who sustained ankle sprains had a preseason COMP score of 2.01 +/- 0.32 (Mean +/- SD), while athletes who did not sustain ankle injuries had a score of 1.74 +/- 0.31. Higher postural sway scores corresponded to increased ankle sprain injury rates (p = 0.001). Subjects who demonstrated poor balance (high sway scores) had nearly seven times as many ankle sprains as subjects who had good balance (low sway scores) (p = 0.0002.) CONCLUSION: In this cohort of high school basketball players, pre-season balance measurement (postural sway) served as a predictor of ankle sprain susceptibility.

Benefits of early anti-inflammatory medication following acute ankle injury.

A total of 122 patients presenting with acute ankle injuries within 6 h of injury were entered into a double-blind study. Treatment consisted of a standardized regimen of physiotherapy and elastic support for all patients, who were then randomized into two groups. One group received immediate ibuprofen (2400 mg/day) while the other group received placebo medication for 48 h, followed by ibuprofen (2400 mg/day) from the 3rd day onwards, i.e. delayed antiinflammatory treatment. Assessments were made by means of a daily diary and also by clinical and radiological examination. The immediate treatment group demonstrated more rapid recovery by day 7 in terms of regression of swelling (P less than 0.01) and clinician's impression of severity (P less than 0.05). This group also tended to consider their ankle more able to bear weight at this stage (P = 0.05). In comparison with an earlier study, in which the only active treatment was an elastic support, a greater percentage of patients recovered earlier in the present study. The incidence of side-effects was low. Immediate high-dose ibuprofen is therefore recommended as treatment for moderate to severe acute ankle injuries.

Chronic ankle morbidity in obese children following an acute ankle injury.

OBJECTIVE: To examine the relationship between childhood obesity as measured by body mass index (BMI) and long-term morbidity after an acute ankle sprain. DESIGN: Six-month prospective cohort study with follow-up telephone questionnaires at 6 weeks and 6 months. SETTING: Cincinnati Children's Hospital Medical Center emergency department. PATIENTS: Children between the ages of 8 and 18 years who presented with a chief complaint of an acute ankle injury were enrolled in the study. Children with ankle fractures were excluded. Exposed children were defined as those with a BMI in the 85th or greater percentile for age. Nonexposed children were defined as those with a BMI in the less than 85th percentile for age. MAIN OUTCOME MEASURES: Persistent symptoms of pain, swelling, or weakness; pain during or after exercise; and recurrent ankle injury. RESULTS: A total of 199 children were enrolled. The exposed and nonexposed groups were similar in terms of sex, age, and ethnicity. A total of 164 (93%) had complete follow-up at 6 months. Six months after an ankle injury, children with a BMI in the 85th or greater percentile for age were more likely to sustain persistent symptoms (relative risk, 1.70; 95% confidence interval, 1.10-2.61). CONCLUSION: Overweight children are more likely to have persistent symptoms 6 months after an acute ankle sprain.
