Background There are sparse data available regarding outcome of meniscal repair performed at the time of ACL reconstruction in the pediatric and adolescent population. Purpose To review the results of meniscal repair performed at the time of ACL reconstruction in pediatric and adolescent patients. Study Design Case series; Level of evidence, 4. Methods The records of all patients age 18 years or younger who underwent meniscal repair at the time of ACL reconstruction between 1990 and 2005 were reviewed. Ninety-nine patients (56 female, 43 male) with an average age of 16 years (range, 13-18) were included. Average injury to surgery interval was 107 days (range, 2-1109). Clinical outcomes were assessed at a mean of 8 years postoperatively (range, 2-19). A multivariate model was used to compare this cohort with a previously published cohort of patients with isolated meniscal tears. Results The clinical success rate of meniscal repair was 84% for simple tears, 59% for displaced bucket-handle tears, and 57% for complex tears (74% overall). Twenty-six menisci (26% overall) failed repair and 25 patients underwent repeat arthroscopic surgery (19 partial meniscectomies, 6 re-repairs). The average Tegner and International Knee Documentation Committee scores were 6.2 (range, 2-10) and 90.3 (range, 52-100), respectively. Risk factors for failure included complex and bucket-handle tear (P = .01), medial meniscal tears (P = .03), and skeletal immaturity (P = .01). Compared with isolated meniscal repairs in a similar pediatric and adolescent population, complex tears repaired in combination with ACL reconstruction did significantly better (57% vs 13%; P = .004). Conclusion Clinically successful repair of meniscal tears treated at the time of ACL reconstruction in patients 18 years or younger depends on tear type, with complex and bucket-handle tears being negative prognostic factors. Complex tears have a higher rate of clinical success when repaired at the time of ACL reconstruction versus when repaired in isolation.

Following the death of a youth hockey coach in a fight with a parent in 2000, the Mayo Clinic Sports Medicine Center and Minnesota Hockey collaborated to implement a three-component Hockey Education Program (HEP). HEP was initiated in 2003 to ensure youth players develop sportsmanship, skills, and a Fair Play approach to the game. Another goal was to decrease attrition of players, coaches, and officials. Coaching Excellence, a component of HEP, is based on 25 years of youth sport research. The HEP manuals Coaches Who Never Lose and Sports and Your Child contain the philosophy, objectives, and guidelines to ensure implementation of HEP components across players, coaches, and parents. The Skill Development component emphasizes learning age-appropriate hockey skills though skill progression. Increasing the practice-to-game ratio to 3–4 practices per game greatly increases the maximum time players skate with the puck during developmental years. Pre- and post-season Skills Challenges allow coaches, players, and parents to gauge improvement, and structure practices to address identified skill deficits. The Fair Play (FP) component emphasizes sportsmanship. Teams earn a FP point each game if they incur less than a preset number of penalty minutes. A coach receiving a game misconduct or a parent∕spectator asked to leave the game will cause the team to forfeit their FP point. FP points are factored into league standings across the state. This past season, 17 678 records of game data were obtained and 25 % (4420) were randomly selected for analysis. The data analysis permits comparison across seasons and changes are made accordingly. Based on four years of data, most Minnesota youth hockey games are played in a sportsmanlike manner. Checking from behind and head contact penalties have decreased since the penalty minutes for these dangerous infractions were increased.

Ice hockey is a fast-paced, aggressive sport whose participants are subject to relatively high rates of injury. Although there is a growing emphasis on the epidemiology of ice hockey research and its application towards reducing injuries, the literature has never been organized into an accessible database. Ice hockey is played in North America, Europe, Scandinavia, the U.K., and several other non-English speaking countries, yet injury reports not written in English are often ignored in review articles. The purpose of this project was to synthesize the existing world literature on ice hockey injuries into a framework of epidemiologic criteria, accessible in an organized, retrievable library. An extensive search of the following databases was done: MEDLINE, BIOSIS, EMBASE, NTIS, CURRENT CONTENTS, DISSERTATION ABSTRACTS, SPORT DISCUS, CINAHL, and WEB OF SCIENCE. Key words used were “ice hockey” and “injuries,” and the search range was 1966 to July 2007. Endnote X (Thompson Corp., Stamford, CT) was used for reference compilation. Eight hundred sixty seven documents were catalogued, from 27 countries in 8 languages. Documents were first categorized by type, including injury (226), equipment (45), case reports (94), review articles (294), editorials (39), or as focusing on the physiological, psychological, or medical aspects of ice hockey (169). Documents were then subdivided by study type and whether they were prospective (117) or retrospective (109). Further subdivisions beyond these levels were based on the inclusion of certain critical epidemiological criteria, including exposure time, a clear definition of “injury,” and the level of play, among others. This comprehensive database should make future ice hockey research more efficient, as well as promote sound epidemiology and a more global perspective.

Background Treatment of the multiligament-injured knee remains controversial. Purpose To compare clinical and functional outcomes of a consecutive series of multiligament-injured knees that underwent repair of the fibular collateral ligament (FCL) and posterolateral corner (PLC), followed by delayed cruciate ligament reconstructions, with those that had single-stage multiligament reconstruction. Study Design Cohort study; Level of evidence, 3. Methods Patients with multiligament knee injury treated by a single surgeon were identified in our prospective database. Between February 2004 and May 2005, patients underwent repair of medial- and lateral-sided injuries, followed by delayed cruciate ligament reconstructions. Between May 2005 and February 2007, patients underwent single-stage multiligament knee reconstruction. All patients followed a standard rehabilitation protocol. Inclusion criteria were minimum 2-year follow-up and multiligament knee injury including the FCL/PLC. International Knee Documentation Committee subjective and Lysholm scores and objective clinical data were documented. Results We identified 45 knees (42 patients); 17 knees (14 patients) were excluded, leaving 28 knees (28 patients) in the study. The repair/staged group (10 knees in 10 patients) had a mean follow-up of 34 months (range, 24-49 months). The reconstruction group (18 knees in 18 patients) had a mean follow-up of 28 months (range, 24-41 months). Four of the 10 FCL/PLC repairs (40%) and 1 of the 18 FCL/PLC reconstructions (6%) failed (P = .04). After revision reconstructions, there were no statistically significant differences between mean International Knee Documentation Committee subjective scores (79 vs. 77, P = .92) and mean Lysholm scores (85 vs 88, P = .92). Regression analysis showed no effect on failure based on age, sex, injury mechanism, time to surgery, interval between stages, total number of ligaments injured, or location of tear. Conclusion Our series demonstrated a statistically significant higher rate of failure for repair compared with reconstruction of the FCL/PLC. Reconstruction of the FCL/PLC structures is a more reliable option than repair alone in the setting of a multiligament knee injury.

AbstractWhile it is generally accepted that most partial and isolated medial collateral ligament (MCL) injuries can be treated non‐operatively, ideal treatment of the MCL in multi‐ligament knee injuries remains controversial. High failure rates with repair of the posterolateral corner in the multi‐ligament injured knee have been recently reported, favoring reconstruction instead. The same maybe true for MCL injuries, however evidence‐based treatment recommendations are lacking in the current orthopedic literature. The purpose of this study was to perform an evidence‐based systematic review of the operative management (repair and/or reconstruction) of the MCL in the setting of multi‐ligament knee injuries. A comprehensive search of MEDLINE and the Cochrane databases for all relevant articles published in English from 1978 to 2008 on the outcomes of surgical management (repair and/or reconstruction) of the MCL in the setting of combined ligament injuries was performed. Inclusion criteria included articles published in (1) English, (2) on human subjects, (3) between the years of 1978 and 2008, (4) had minimum 12‐month follow‐up, with a mean of at least 24 months, (5) on surgical management of MCL injuries, (6) associated with multi‐ligament injuries (three or more ligaments) and/or knee dislocation, and (7) reported objective outcome data on the respective patient cohorts. Exclusion criteria consisted of technique papers, case reports, studies that included fractures associated with MCL injury and those that included pediatric patients. The review identified eight relevant studies. Five articles focused on MCL repair, while three articles focused on MCL reconstruction. No prospective studies compared MCL repair or reconstruction with non‐operative treatment or directly compared MCL reconstruction with MCL repair. Currently there is a paucity of objective data on the outcomes regarding surgical management of MCL tears in the combined ligament injured knee. This systematic review demonstrated satisfactory results in both repair and reconstruction groups. Future objective outcome‐based studies as well as comparative studies are needed to further evaluate the optimal treatment modality before evidence‐based recommendations can be made. Therefore, individual treatment decisions for each patient should be based on the characteristics and nature of the injury.

Purpose The purpose of this systematic review was to address the treatment of multiligament knee injuries, specifically ( 1 ) surgical versus nonoperative treatment, ( 2 ) repair versus reconstruction of injured ligamentous structures, and ( 3 ) early versus late surgery of damaged ligaments. Methods Two independent reviewers performed a search on PubMed from 1966 to August 2007 using the terms “knee dislocation,” “multiple ligament–injured knee,” and “multiligament knee reconstruction.” Study inclusion criteria were ( 1 ) levels I to IV evidence, ( 2 ) “multiligament” defined as disruption of at least 2 of the 4 major knee ligaments, ( 3 ) measures of functional and clinical outcome, and ( 4 ) minimum of 12 months' follow‐up, with a mean of at least 24 months. Results Four studies compared surgical treatment with nonoperative treatment. There was a higher percentage of excellent/good International Knee Documentation Committee (IKDC) scores (58% v 20%) in surgically treated patients, as well as higher rates for return to work (72% v 52%) and return to full sport (29% v 10%). Two studies compared repair with reconstruction of damaged structures, with similar mean Lysholm scores (88 v 87) and excellent/good IKDC scores (51% v 48%). However, repair of the posterolateral corner had a higher failure rate (37% v 9%). Similarly, repair of the cruciates yielded decreased stability and range of motion and a lower return to preinjury activity levels (0% v 33%). There were 5 studies comparing early surgery (≤3 weeks) with late surgery. Early treatment resulted in higher mean Lysholm scores (90 v 82) and a higher percentage of excellent/good IKDC scores (47% v 31%), as well as higher sports activity scores (89 v 69) on the Knee Outcome Survey. Conclusions Our review suggests that early operative treatment of the multiligament‐injured knee yields improved functional and clinical outcomes compared with nonoperative management or delayed surgery. Repair of the posterolateral corner may yield higher revision rates compared with reconstruction.
