Different patient and activity-related characteristics result in different injury profiles for patients with anterior cruciate ligament and posterior cruciate ligament injuries. Knee Surg Sports Traumatol Arthrosc 2023; 31:308-315. [PMID: 36029316 PMCID: PMC9859844 DOI: 10.1007/s00167-022-07131-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Accepted: 08/17/2022] [Indexed: 01/25/2023]
Abstract
PURPOSE To compare patient characteristics including patient sex, age, body mass index (BMI), activities at the time of injury and injury profiles in patients with anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) injuries. METHODS Data were obtained from the Swedish National Knee Ligament Registry. Two study groups were created: (1) index ACL reconstruction (ACL group) and (2) index PCL reconstruction (PCL group). Between-group differences were investigated using Fisher's exact test and Fisher's non-parametric permutation test for dichotomous variables and continuous variables, respectively. RESULTS Of 39,010 patients, 38,904 were ACL injuries. A larger proportion of patients with combined injuries to the PCL, meniscus and cartilage were female, aged > 25 years and with a BMI of > 35 kg/m2 compared with patients with combined injuries to the ACL, meniscus and cartilage. An isolated ACL injury was more commonly found in males, while all other injury profiles of ACL, including combined injuries with meniscus, cartilage and collateral ligament injuries, were more frequently observed in females. The PCL injuries were sustained either during pivoting sports, non-pivoting sports or were traffic-related. CONCLUSION Different patient characteristics (BMI, age and sex), and activities at the time of injury (sport- versus traffic-related activities), resulted in distinct injury profiles for the ACL and PCL groups. These findings provide valuable information of the way specific injury patterns of cruciate ligament injuries occur, and subsequently may help clinicians with the diagnostic process of ACL and PCL injuries.

Return to Play and Player Performance After Meniscal Tear Among Elite-Level European Soccer Players: A Matched Cohort Analysis of Injuries From 2006 to 2016. Orthop J Sports Med 2022; 10:23259671211059541. [PMID: 35047646 PMCID: PMC8761888 DOI: 10.1177/23259671211059541] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Accepted: 08/24/2021] [Indexed: 11/17/2022] Open
Abstract
Background: Meniscal injuries are extremely common in soccer athletes, and little is known about postrecovery performance. Purpose: To (1) identify characteristics associated with return to play (RTP) to the same league level and (2) evaluate long-term effects that injury and management approach may have on player performance. Study Design: Cohort study; Level of evidence, 3. Methods: Using publicly available records, we identified athletes who sustained meniscal tears across the 5 major European soccer leagues (English Premier League, Bundesliga, La Liga, Ligue 1, and Serie A) between 2006 and 2016. Injured athletes were matched to controls 1:2 by demographics and performance. Investigations included rate of RTP to the same league level, reinjury, player characteristics associated with RTP within 2 seasons, long-term availability, field time, and performance metrics standardized to 90 minutes of play during the next 4 seasons. Results: A total of 250 players sustaining meniscal tears were included, of which 106 (42%) received surgical management. Median absence was 57.5 days (interquartile range [IQR], 35-92) or 7 games (IQR, 4-12). Rate of RTP was 70%, and the reinjury rate 5% if a player could RTP. Age greater than 30 years was a negative predictor for RTP (odds ratio [OR], 0.62; P = .002), whereas higher preinjury goals per game (OR, 2.80; P = .04) and surgical management (OR, 1.38; P = .002) were positive predictors for RTP. Surgical management was associated with higher long-term availability (P < .01). As compared with the control, there were no significant differences in field time or performance metrics after RTP, either overall or by player position. As compared with nonoperative management, defenders undergoing surgery demonstrated decreased field time. Attackers and midfielders demonstrated similar field time and performance regardless of management. Conclusion: RTP of elite soccer athletes sustaining meniscal tear is contingent on age, preinjury performance, and management approach. Those who RTP to the same league level can be expected to demonstrate equivalent field time, performance, and long-term availability as noninjured athletes.

Clinical outcomes of combined anterior cruciate ligament and anterolateral ligament reconstruction: a systematic review and meta-analysis. Knee Surg Relat Res 2021; 33:33. [PMID: 34556187 PMCID: PMC8461945 DOI: 10.1186/s43019-021-00115-1] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 09/08/2021] [Indexed: 01/04/2023] Open
Abstract
OBJECTIVES To compare the clinical outcomes of isolated anterior cruciate ligament (ACL) reconstruction with combined reconstruction of the ACL and anterolateral ligament (ALL) of the knee. METHODS A search was conducted on the PubMed, Medline, Google Scholar, EMBASE, and Cochrane library databases, in line with the PRISMA protocol. The indexation terms used were "anterior cruciate ligament" OR "acl" AND "anterolateral ligament" AND "reconstruction." Articles that compared patients submitted to combined ACL and ALL reconstruction with those submitted to isolated reconstruction of the ACL, with levels of evidence I, II, and III, were included. Studies with follow-up of less than 2 years and articles that did not use "anatomical" techniques for ALL reconstruction, such as extraarticular tenodesis, were excluded. A meta-analysis with R software was conducted, with a random effects model, presented as risk ratio (RR) or mean difference (MD), with a 95% confidence level (CI) and statistically significant at p < 0.05. RESULTS Ten articles were selected, with a total of 1495 patients, most of whom were men, of whom 674 submitted to ACL and ALL reconstruction and 821 to isolated ACL reconstruction. Combined ACL and ALL reconstruction exhibited a statistically significant advantage in residual pivot shift (RR 0.34, 95% CI 0.24-0.47, I2 = 0%, p < 0.01), rerupture rate (RR 0.34, 95% CI 0.19-0.62, I2 = 0%, p < 0.01), Lachman test (RR 0.59, 95% CI 0.40-0.86, I2 = 21%, p < 0.01), and postoperative Lysholm score (MD 2.28, CI 95% 0.75-3.81, I2 = 73%, p < 0.01). CONCLUSIONS Combined ACL and ALL reconstruction obtained better postoperative clinical outcomes when compared with isolated ACL reconstruction, especially in reducing residual pivot shift and rerupture rate.

Return-to-Play Times and Player Performance After ACL Reconstruction in Elite UEFA Professional Soccer Players: A Matched-Cohort Analysis From 1999 to 2019. Orthop J Sports Med 2021; 9:23259671211008892. [PMID: 34104662 PMCID: PMC8165856 DOI: 10.1177/23259671211008892] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Accepted: 01/04/2021] [Indexed: 11/17/2022] Open
Abstract
Background: Anterior cruciate ligament (ACL) rupture is one of the most common injuries afflicting soccer players and requires a lengthy recovery processes after reconstructive surgery. The impact of ACL reconstruction (ACLR) on return to play (RTP) time and player performance in professional soccer players remains poorly studied. Purpose/Hypothesis: To determine player performance and RTP rate and time after ACLR in elite professional soccer players with a retrospective matched-cohort analysis. We expected that the RTP time and rate will be similar to those of other professional-level athletes. Study Design: Cohort study; Level of evidence, 3. Methods: Included were 51 players from 1 of the 5 elite Union of European Football Associations (UEFA) soccer leagues who suffered a complete ACL rupture between 1999 and 2019. These athletes were matched by position, age, season of injury, seasons played, and height and compared to uninjured control players. Change in performance metrics for the 4 years after the season of injury were compared with metrics 1 season before injury. Univariate 2-group comparisons were performed using independent 2-group t tests; Wilcoxon rank-sum tests were used when normality of distributions was violated. Results: Overall, 41 players (80%) returned to play after ACL rupture, with 6 (12%) experiencing a subsequent ipsilateral or contralateral ACL tear. The mean (±SD) RTP time for soccer players after ACLR was 216 ± 109 days (26 ± 18 games). Injured athletes played significantly fewer games and minutes per season and recorded inferior performances for 2 seasons after their injury (P < .001). However, the game performance of injured players equaled or exceeded that of their matched controls by season 3 after injury, with the exception of attackers, who demonstrated a continued decline in performance (P < .001). Conclusion: Results indicated that the mean RTP time for soccer players after ACLR is short in comparison with other major sports leagues (216 days). However, RTP rates were high, and rerupture rates were comparable with those of other sports. With the exception of attackers, player performance largely equaled or exceeded that of matched controls by the third postinjury season.

Abstract
BACKGROUND Forces acting on the knee are different in contact and non-contact mode of injuries causing anterior cruciate ligament (ACL) tear. Purpose of this study was to determine the effect of mode of injury on the occurrence of meniscal tear and chondral damage in ACL tear. METHOD 72 athletes with acute ACL injury (<3 months) were enrolled in the study. Depending on the mode of injury, athletes were divided into two groups - group A (non-contact mode of injury) and group B (contact mode of injury). 49/72 athletes had the non-contact mode of injury (group A), and 23/72 athletes had contact mode of injury (group B). Meniscal tear and chondral damage seen at the time of ACL reconstruction surgery was noted. All athletes were assessed at 12 months follow-up for return to sports, Lysholm score, and WOMAC score. RESULTS In group A, 35/49 (71%) athletes and in group B, 9/23(39%) athletes had meniscal tear (p = 0.009). Medial meniscus was more commonly injured in group A [24/49] as compared to group B (5/23; p = 0.03). Chondral damage was also more commonly seen in group A [26/49] as compared to group B (5/23; p = 0.01). At one-year follow-up, 65% of the athletes from group B returned to sports as compared to 57% of the athletes from group A (p-value = 0.6). WOMAC score in group A and B was 95.5 ± 4.88 and 96 ± 4.39 respectively (p = 0.67). Lysholm score in group A and B was 1.02 ± 1.7 and 0.96 ± 1.2 respectively (p = 0.88). CONCLUSION Non-contact mode of injury was associated with a higher incidence of meniscal tear and chondral damage. However, the mode of injury does not affect the functional outcome of ACL reconstruction surgery.

Abstract
INTRODUCTION Elite and Olympian athletes are often stretching the upper limits of normal physiology and biomechanics of the musculoskeletal system in their efforts to excel in their sport. For them to get back to their sport at the same level after injury, the management, repair techniques, and rehabilitation protocols should be robust to permit healing of tissues to allow supra-normal loading and performance. The knee and the meniscus are commonly injured in these sports. Yet, the incidence, mechanisms, types of injuries to the meniscus, and their management are not known across different sports in the Olympics. METHODS We set out to look into the incidence and the trends of publications on meniscal injuries of the knee in Olympic games. A search of the PubMed and Scopus for these injuries using a search strategy gave 79 and 116 articles, respectively. RESULTS There were very few publications giving the incidence of meniscal injuries in the Olympics. Football is the sport with the highest rate of meniscal injuries. Different sports are popular in different countries, and depending on the popularity and the country reporting these injuries, incidences differed. There was data available from India and Brazil for Elite athlete from diverse sports, whereas most data from other countries were for football and soccer. Knee was found to be the second most commonly injured part of the body in both Winter and Summer Olympics as well as the Youth Winter Olympics. Data were not available from the Youth Summer Olympics to make any conclusions. The number of publications on this topic is low. We presented the timeline of publications and citations of articles on this topic. The top country, language, journal, university, and author were USA, English, American Journal of Sports Medicine, Hospital of Special Surgery in New York and Brophy RH, respectively. The data on the risk factors for meniscal injuries were analyzed, discussed, and presented for football, as this was the most extensively studied sport. CONCLUSIONS Even though the knee is one of the commonly injured anatomical locations in elite athletes, there is a lack of literature on meniscal injuries in this subset of population. We looked at possible reasons and made recommendations to improve data collection on these injuries.

Abstract
Background: Skeletally immature patients show a higher rate of anterior cruciate ligament
(ACL) reruptures. A better understanding of the risk factors for an ACL
rerupture in this population is critical. Purpose/Hypothesis: The objective of this study was to analyze preoperative, intraoperative, and
postoperative characteristics of pediatric patients undergoing ACL
reconstruction and determine the relationship of these factors with an ACL
rerupture. It was hypothesized that patients with worse activity scores and
knee function at the time of return to activity would have a higher rate of
ACL reruptures at midterm follow-up. Additionally, it was hypothesized that
most ACL reruptures would occur before age 20 years in the study
population. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 65 skeletally immature patients (age <16 years) with ACL
ruptures underwent reconstruction with a quadruple hamstring tendon graft
between 2002 and 2016. Of these patients, 52 were available for the study.
Patient characteristics, surgical details, Tegner and Lysholm scores, and
ACL reconstruction outcomes were recorded. Patients were analyzed and
compared according to ACL rerupture occurrence. Results: Of the 52 patients, 18 (34.6%) experienced an ACL rerupture after
reconstruction. The majority of reruptures (77.8%) occurred before age 20
years. There were 2 patients who sustained ACL reruptures during the
rehabilitation period before they returned to activity. The majority of
reruptures occurred after 12 months (83.2%), with 66.6% occurring after 24
months. Upon returning to activity between 6 and 9 months postoperatively,
patients who ended up with intact ACL grafts reported 69% higher mean Tegner
scores (P = .006) and 64% higher mean Lysholm scores than
patients who sustained ACL reruptures (P < .001). Within
the limits of this study, we could identify no statistical relationship
between the rate of ACL reruptures and different sport types, surgical
techniques, or associated injuries (P > .05). Conclusion: Skeletally immature patients who underwent ACL reconstruction and sustained
ACL reruptures had lower Tegner and Lysholm scores upon returning to
activity than patients without ACL reruptures. In addition, most ACL
reruptures occurred in patients younger than 20 years (77.8%) and after 24
months postoperatively (66.6%).

Abstract
PURPOSE To compare the outcomes of patients with an arthroscopic floating meniscus sign at 24-month follow-up when treated with and without medial compartment reconstruction surgery. Another aim of the present study was to compare magnetic resonance imaging and arthroscopic findings directly related to the characterization and localization medial collateral ligament (MCL) injuries. METHODS A total of 112 patients diagnosed with combined anterior cruciate ligament (ACL)-MCL grade II injuries to be treated with ACL reconstruction surgery were included in the study. During arthroscopy, patients diagnosed with the "floating meniscus" sign were divided into 2 groups: group 1 (n = 58) was treated with ACL and medial compartment reconstruction surgery and group 2 (n = 54) was treated with ACL reconstruction and nonsurgical medial compartment treatment. Return to competitive sports (Tegner score), Lysholm scores, ACL reconstruction failure, and residual MCL laxity were evaluated 6, 12, and 24 months after surgery. RESULTS After 24 months, patients from group 1 (n = 58) had an average Tegner score of 8.98 and Lysholm score of 89.67; 2 patients presented with ACL reconstruction failure and none presented with residual MCL laxity. Patients from group 2 (n = 54) had an average Tegner score of 6.7 and Lysholm score of 78.12; 16 patients presented with ACL reconstruction failure and 13 presented with residual MCL laxity. CONCLUSIONS In the presence of a floating meniscus arthroscopic sign, patients with combined ACL and grade II MCL injuries treated with ACL and MCL reconstruction surgery had significantly lower frequency of ACL reconstruction failure, residual MCL laxity, and better Tegner and Lysholm scores at 24 months' follow-up (P < .05). Additionally, magnetic resonance imaging and arthroscopy differed significantly (P < .05) in their ability to identify mid-substance and tibial site MCL injuries.

Abstract
BACKGROUND Soccer is one of the most common international sports in which ACL injuries occur, with previous studies reporting high return-to-play rates following ACL reconstruction (ACLR). Return-to-play analysis fails to take into consideration how effective a player remains once returning to competition. The aims of this study are to provide a large-scale international analysis of return-to-play and player performance statistics among professional soccer athletes following ACLR. METHODS Using publicly available sources, professional soccer athletes who have undergone ACLR between the 1996 and 2015 seasons were identified. Player metrics including statistical performance, recovery time, and return-to-play rates were analyzed both before and after reconstruction. Furthermore, player performance statistics during each of three consecutive seasons post-ACLR were compared. RESULTS A total of 176 athletes who underwent ACLR were included in this study. The return-to-play rate was 93.2% (164 athletes). Cumulative post-surgical statistical analysis of ACLR players demonstrated fewer games/season, minutes/season, minutes/game, goals/season, and more fouls/season following ACLR (p < 0.04). Analysis of player performance statistics suggests that athletes do not return to their baseline number of games/season and minutes/game until two and three seasons post-ACLR, respectively. At three seasons post-ACLR, athletes are still starting fewer games/season and scoring fewer goals/90 min (p < 0.04). CONCLUSION Return-to-play rate is high following ACLR; however, athletes exhibit poorer statistical performance, especially in the first few seasons upon return. Our data shows that athletes continue to start fewer games/season and score fewer goals/90 min at three seasons post-ACLR.

The lack of standardized outcome measures following lower extremity injury in elite soccer: a systematic review. Knee Surg Sports Traumatol Arthrosc 2018; 26:3109-3117. [PMID: 29955929 DOI: 10.1007/s00167-018-5032-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2018] [Accepted: 06/22/2018] [Indexed: 02/05/2023]
Abstract
PURPOSE Sport-specific, performance-based outcomes are increasingly used to improve evaluation of treatment efficacy in elite athletes; however, its usage in elite soccer may be limited. The purpose of this investigation is to (1) assess current outcome reporting in elite soccer; (2) identify any variability in reporting of outcomes; and (3) determine how sport-specific performance-based outcomes are utilized to assess treatment efficacy in elite soccer. METHODS A systematic review of the Pubmed, MEDLINE, and Embase, Scopus, SportDiscus, CINAHL and HealthSource: Nursing databases was performed without limitation on publication year. Inclusion criteria were (1) reporting of outcomes after a (2) lower extremity injury in (3) elite soccer players. The study's population, type of injury, return to play, as well as functional, objective, and sport-specific performance-based outcomes were extracted from each article. The methodological index for nonrandomized studies was used for quality assessment. RESULTS Twenty-one studies were selected after application of the inclusion and exclusion criteria. Objective outcomes were reported by 6 (29%) studies, and 6 (29%) employed patient-reported outcomes. The visual analog scale, Lysholm, and Tegner scores were the most common patient-reported outcomes (PROs). Return to play was reported by 18 (86%) studies, and only 2 (10%) utilized sport-specific performance-based outcomes. Despite the majority of studies reporting return to play, variation was seen in the definitions, and 15 (71%) studies reported the activity level of the players at final follow-up. CONCLUSION Assessment of treatment efficacy is limited in elite athletes, and PROs lack the sensitivity to identify residual performance deficits after an injury. Although performance-based measures are available at the elite level, these outcomes were seldom used for evaluation of treatment efficacy. CLINICAL RELEVANCE When treating elite soccer players, patient-reported outcome measures lack the sensitivity to detect changes in patient function, thus performance-based metrics may be more efficacious in assessing return from injury in these patients. LEVEL OF EVIDENCE IV.
