Arp K, Nedermark J, Ingwersen KG, Ageberg E, Varnum C, Viberg B. Which patients need anterior cruciate ligament reconstruction after initial treatment with rehabilitation? A scoping review. Knee Surg Sports Traumatol Arthrosc 2024. [PMID: 39045722 DOI: 10.1002/ksa.12378] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 07/04/2024] [Accepted: 07/08/2024] [Indexed: 07/25/2024]
Abstract
PURPOSE Some patients with anterior cruciate ligament (ACL) injury initially treated with rehabilitation need ACL reconstruction (ACLR); yet, it is unclear what characterizes these patients. This review aimed to describe predictors for ACLR in patients initially treated with rehabilitation. METHODS A systematic literature search was performed in the Cochrane, Embase, Medline, SportsDiscus and Web of Science databases from inception to 21 February 2023. Articles describing characteristics in adult patients with ACL injury undergoing ACLR after a minimum of 5 weeks rehabilitation were included. It was a priori chosen that characteristics described in at least three articles were considered more certain and could be defined as a predictor for ACLR, and those described in less than three articles were considered less certain and therefore defined as possible predictors. Articles were screened by two independent reviewers. The study was originally intended as a systematic review with meta-analysis, but in case of limited data, we would convert it to a scoping review, as was the case for this review. RESULTS There were 22,836 studies identified, and 181 full texts were screened, of which 10 papers were finally included. Only lower age and higher preinjury activity level were identified as predictors for ACLR. Another 12 possible predictors were identified in single studies. Through an iterative process, potential predictors were categorized into four groups: patient demographics, knee function, patient-reported outcome measures and anatomical structures. CONCLUSION Lower age and higher preinjury activity level were the only predictors for ACLR after initial treatment with rehabilitation. While younger and highly active patients show a higher need for ACLR, more studies focussing on predictors and reasons for delayed ACLR are warranted. LEVEL OF EVIDENCE Level II.

[PMID: 38699196 PMCID: PMC11064852 DOI: 10.7717/peerj.17279] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2023] [Accepted: 04/01/2024] [Indexed: 05/05/2024] Open
Abstract
Background Inconsistent results have been obtained regarding the association between return-to-sport (RTS) testing and the risk of subsequent re-injury following anterior cruciate ligament reconstruction (ACLR). We therefore conducted a systematic review and meta-analysis to assess the potential association between passing of RTS and the risk of re-injury for patients after ACLR. Methods This meta-analysis was registered in INPLASY with the registration number INPLASY202360027. The electronic databases MedLine, EmBase, and the Cochrane library were systematically searched to identify eligible studies from their inception up to September 2023. The investigated outcomes included knee injury, secondary ACL, contralateral ACL injury, and graft rupture. The pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using the random-effects model. Results A total number of nine studies involving 1410 individuals were selected for the final quantitative analysis. We noted that passing RTS test was not associated with the risk of subsequent knee injury (OR: 0.95; 95% CI: 0.28-3.21; P = 0.929), secondary ACL injury (OR: 0.98; 95% CI: 0.55-1.75; P = 0.945), and contralateral ACL injury (OR: 1.53; 95% CI: 0.63-3.71; P = 0.347). However, the risk of graft rupture was significantly reduced (OR: 0.49; 95% CI: 0.33-0.75; P = 0.001). Conclusions This study found that passing RTS test was not associated with the risk of subsequent knee injury, secondary ACL injury, and contralateral ACL injury, while it was associated with a lower risk of graft rupture. Thus, it is recommended that patients after ACLR pass an RTS test in clinical settings.

Abstract
Objective This study was conducted to see whether those who had anterior cruciate ligament (ACL) reconstructions on their dominant legs performed better than those who had them on their nondominant legs 1-10 years after the surgery. Materials and Methods An examination of people who sustained injuries to their dominant (n = 25) and nondominant (n = 25) legs between 1 and 10 years after ACL repair was undertaken in a cross-sectional research with 50 people aged 20-38. Everyone takes the fear avoidance belief questionnaire for physical activity (FABQ-PA), the lower extremity functional scale (LEFS), and the anterior cruciate ligament return to sport after injury (ACL-RSI) survey. Results There was no statistically significant difference between the groups on the ACL-RSI, LEFS, and FABQ-PA (U = 254, P = 0.26; U = 314.4, P = 0.95; and U = 279.4, P = 0.53 correspondingly). Conclusion Functional performance and patient mental health should be evaluated 1-10 years after ACL surgery. However, there is no correlation between which leg was the dominant one and the results. As a result, it has been shown that both dominant and nondominant leg injuries heal similarly over time. Future studies should examine additional variables that affect healing and return-to-sport results to improve rehabilitation and optimize long-term functional outcomes for individuals after ACL repair.

Analgesic effect of nitrous oxide during manual therapy after anterior cruciate ligament reconstruction: a study protocol for a randomized controlled trial. Trials 2023; 24:764. [PMID: 38012761 PMCID: PMC10683199 DOI: 10.1186/s13063-023-07732-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2023] [Accepted: 10/14/2023] [Indexed: 11/29/2023] Open
Abstract
BACKGROUND Many patients during manual therapy after anterior ligament reconstruction will experience severe pain, which has a negative impact on their rehabilitation. However, there is rarely an analgesic method for these patients during rehabilitation. Nitrous oxide with rapid analgesic and sedative effects is often used to relieve pain in minor procedures. The purpose of this study is to determine whether or not nitrous oxide analgesia decreases pain compared to oxygen during manual therapy after anterior ligament reconstruction. METHODS/DESIGN This single-center, randomized, double-blind and controlled trial will recruit 120 patients. Patients ≥ 18 years old undergoing manual therapy after anterior ligament reconstruction (1 month post-operative) with acute pain (VAS ≥ 4) are included. The main exclusion criteria included the following: pulmonary embolism, intestinal obstruction, pneumothorax. Patients will be randomly allocated to the intervention group (A) and the control group (B) in a ratio of 1:1. Doctors, therapists, patients, and data collectors are all blind to the study. The manual therapy will be performed by therapists. Nurses who implemented the intervention handed the doctors envelopes containing the patients' codes and allocation of A or B. Group A will receive a pre-prepared nitrous oxide/oxygen mixture plus conventional treatment (no analgesic) given as 30-min treatment sessions, once daily, and group B will receive oxygen plus conventional treatment (no analgesic) under the same conditions. Assessments will be taken 2 min before the intervention (T0), 5 min after the beginning of the intervention (T1), and 5 min after the intervention finished (T2). The primary outcome is pain score. Secondary outcomes include vital signs, side effects, joint range of motion, adjuvant analgesia need, therapist and patient satisfaction, and whether willing to receive the same gas again. EXPECTED OUTCOMES We expect nitrous oxide inhalation to have a beneficial effect on the pain of patients who receive manual therapy after anterior ligament reconstruction. DISCUSSION If this treatment appears beneficial, it could improve patients' satisfaction and quality of life potentially and even be implemented widely in hospital and rehabilitation settings.

Impact of anterior cruciate ligament surgery on the development of knee osteoarthritis: A systematic literature review and meta-analysis comparing non-surgical and surgical treatments. OSTEOARTHRITIS AND CARTILAGE OPEN 2023; 5:100366. [PMID: 37252633 PMCID: PMC10209532 DOI: 10.1016/j.ocarto.2023.100366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Accepted: 04/24/2023] [Indexed: 05/31/2023] Open
Abstract
Introduction Context: The development of knee osteoarthritis (OA) after anterior cruciate ligament (ACL) injury is now widely recognized. The impact of surgical or non-surgical management on the development of post-traumatic osteoarthritis is still debated in the medical community.Here, we present a meta-analysis comparing the impact of surgical or non-surgical management of ACL injuries on the development of knee OA. Method A systematic literature review was conducted using data from the PubMed, EMBASE, Medline, and Cochrane libraries from February to May 2019. Only randomized clinical trials published between 2005 and 2019 with a non-surgical group and a surgical group were included to explore the onset or progression of knee OA after ACL injury. Trials had to have at least one radiographic endpoint (Kellgren-Lawrence scoring system). Heterogeneity was assessed using the Cochrane's Q and I2 statistical methods. Results Only three randomized controlled trials met the inclusion criteria and were selected for meta-analysis. Of the 343 injured knees included in the studies, 180 underwent ACL reconstruction and 163 underwent non-surgical treatment. The relative risk of knee osteoarthritis was higher after surgery than after non-surgical treatment (RR 1.72, CI 95% [1.18-2.53], I2 = 0%). Conclusion The results of this meta-analysis suggest a predisposition to knee osteoarthritis after ACL reconstruction surgery compared with non-surgical management. Due to the small number of good quality studies available, further well-conducted randomised studies are needed to confirm these findings.

Abstract
BACKGROUND Soccer is the most commonly played team sport in the world and a high-risk sport for anterior cruciate ligament (ACL) injury and subsequent ACL reconstruction (ACLR). PURPOSE To assess the rate of further ACL injury in patients who have undergone ACLR with hamstring tendon autograft after soccer injuries in Australia and to determine factors associated with repeat ACL injury and return to soccer. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS From a prospectively collected database, a series of 1000 consecutive ACLRs using hamstring autografts performed in soccer players were identified. Patients were surveyed at a minimum 5 years after reconstruction, including details of further ACL injuries to either knee, return to soccer or other sports, and psychological readiness per the Anterior Cruciate Ligament Return to Sport after Injury (ACL-RSI) scale. RESULTS Of the 862 participants reviewed, ACL graft rupture occurred in 85 (10%) and contralateral ACL rupture in 68 (8%) within 5 years after the reconstruction. The 5-year ACL graft survivorship was 94% for females and 88% for males. The survivorship of the contralateral ACL was 92% for males and 90% for females. When compared with those aged >25 years, the odds of ACL graft rupture was increased by 4 to 5 times in those aged 19 to 25 years and 3 to 7 times in those ≤18 years. Further ACL injury to the graft or contralateral knee occurred in 44% of males aged ≤18 years. Risk factors for further ACL injury were younger age at time of surgery, male sex, and return to soccer. Graft diameter did not influence ACL graft rupture rates, and 70% of patients returned to soccer after ACLR. The mean ACL-RSI score was 59, and patients who reported more fear of reinjury on this scale were less likely to have returned to soccer. CONCLUSION The prevalence of ACL graft rupture (10%) and contralateral ACL rupture (8%) was near equivalent over 5 years in this large cohort of mostly recreational Australian soccer players. ACLR with hamstring autograft is a reliable procedure, allowing 70% of patients to return to soccer in this high-risk population. Risk factors for further ACL injury are progressively younger age at time of surgery, male sex, and return to soccer. Graft diameter was not a factor in ACL graft rupture, indicating that other factors, particularly age, are of primary importance.

Abstract
Objective To investigate the treatment decision-making process after an anterior cruciate ligament (ACL) injury from patients’, orthopaedic surgeons’ and physiotherapists’ perspectives. Methods The study is a part of the NACOX study, which is designed to describe the natural corollaries after ACL injury. For the present study, a subgroup 101 patients were included. Patients, their orthopaedic surgeons and their physiotherapists, answered a Shared Decision-Making Process (SDMP) questionnaire, when treatment decision for ACL reconstruction surgery (ACLR) or non-reconstruction (non-ACLR) was taken. The SDMP questionnaire covers four topics: “ informed patient”, “ to be heard”, “ involvement” and “ agreement”. Results Most (75–98%) patients considered their needs met in terms of being heard and agreement with the treatment decision. However, fewer in the non-ACLR group compared to the ACLR group reported satisfaction with information from the orthopaedic surgeon (67% and 79%), or for their own involvement in the treatment decision process (67% and 97%). Conclusion and practice implications Most patients and caregivers considered that patients’ needs to be informed, heard and involved, and to agree with the decision about the treatment process, were fulfilled to a high extent. However, patients where a non-ACLR decision was taken experienced being involved in the treatment decision to a lower extent. This implies that the non-ACLR treatment decision process needs further clarification, especially from the patient involvement perspective.

Abstract
Athletes are defined by their ability to move and are often accustomed to pain as it relates to their sports and exercise regime. The forced movement restriction and pain associated with an acute or overuse injury has a profound effect not only on their physical abilities but also on their psychological well-being and social context. With the goal of returning to sport, the rehabilitation focus historically has been on recovery of physical attributes, but more recent research is addressing the psychological factors. This Perspective proposes that-according to the current evidence in sports medicine-the fear that affects choice of treatment, rehabilitation, and return to sports is intertwined with physical capacity and recovery of function. Past injury is also 1 of the main risk factors for a sports injury; therefore, fear of reinjury is not irrational. For an athlete, the fear related to a sports injury encompasses the fear of reinjury along with fear of not being able to return to the sport at their highest performance level-and the fear of having lifelong debilitating pain and symptoms. This Perspective reviews the evidence for the influence of fear of movement and reinjury on choice of treatment, rehabilitation, and return to sport and provides suggestions on how to address this fear during the continuum of treatment and return to sports.

Abstract
Despite the establishment of successful surgical techniques and rehabilitation protocols for anterior cruciate ligament (ACL) reconstruction, published return to sport rates are less than satisfactory. This has led orthopaedic surgeons and researchers to develop more robust patient selection methods, and investigate prognostic patient characteristics. No previous studies have integrated baseline characteristics and responses to patient-reported outcome measures (PROMs) of patients with ACL rupture presenting for surgical review. Patients electing to undergo ACL reconstruction under the care of a single orthopaedic surgeon at a metropolitan public hospital were enrolled in a clinical quality registry. Patients completed Veterans RAND 12-item Health Survey (VR-12) Physical Component Summary and Mental Component Summary scores, Tegner activity scale, and International Knee Documentation Committee (IKDC) questionnaires at presentation. Total scores were extracted from the electronic registry, and a machine learning approach (k-means) was used to identify subgroups based on similarity of questionnaire responses. The average scores in each cluster were compared using analysis of variance (ANOVA; Kruskal-Wallis) and nominal logistic regression was performed to determine relationships between cluster membership and patient age, gender, body mass index (BMI), and injury-to-examination delay. A sample of 107 patients with primary ACL rupture were extracted, with 97 (91%) available for analysis with complete datasets. Four clusters were identified with distinct patterns of PROMs responses. These ranged from lowest (Cluster 1) to highest scores for VR-12 and IKDC (Cluster 4). In particular, Cluster 4 returned median scores within 6 points of the patient acceptable symptom state for the IKDC score for ACL reconstruction (70.1, interquartile range: 59-78). Significant (p < 0.05) differences in PROMs between clusters were observed using ANOVA, with variance explained ranging from 40 to 69%. However, cluster membership was not significantly associated with patient age, gender, BMI, or injury-to-examination delay. Patients electing to undergo ACL reconstruction do not conform to a homogenous group but represent a spectrum of knee function, general physical and mental health, and preinjury activity levels, which may not lend itself to uniform treatment and rehabilitation protocols. The factors driving these distinct responses to PROMs remain unknown but are unrelated to common demographic variables.

Abstract
PURPOSE The purpose of this study is to evaluate the reasons why athletes do not return to play (RTP) following anterior cruciate ligament (ACL) reconstruction from a large single-centre database. METHODS The institutional ACL registry was screened for patients that had undergone a primary ACLR and had RTP status reported at 24-month follow-up. The reasons that patients were unable to RTP at 24 months were evaluated. The ACL-Return to Sport Index (ACL-RSI) was evaluated at baseline and 24-month follow-up to evaluate psychological ability to RTP. RESULTS At 2 years, 1140 patients returned to play, and 222 had not returned to play. The most common reasons athletes were unable to return was fear of reinjury (27.5%), lack of confidence in performance on return (19.4%) and external life factors (16.6%), i.e. work commitments and family reasons. Other reasons for athletes not returning to play were residual knee pain (10%) and subsequent injury (5%). The ACL-RSI score was significantly lower at diagnosis (40.3 vs. 49.3; p = 0.003) and 2 years (41.8 vs. 78.7; p < 0.0001) in athletes who did not return to play vs. those that did RTP. CONCLUSION The majority of patients that report they have not returned to play do so due to external life and psychological factors associated with their injury, including fear of reinjury and lack of confidence in performance. A small minority of patients were unable to return due to residual knee symptoms or reinjury. Pre-operative psychological assessment and intervention may identify those less likely to RTP and provide an opportunity for targeted interventions to further improve RTP outcomes.

[PMID: 33948447 PMCID: PMC8053763 DOI: 10.1177/23259671211005090] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 02/17/2021] [Indexed: 11/17/2022] Open
Abstract
Background: In the treatment of anterior cruciate ligament (ACL) injuries, there is little evidence of when and why a decision for ACL reconstruction (ACLR) or nonoperative treatment (non-ACLR) is made. Purpose: To (1) describe the key characteristics of ACL injury treatment decisions and (2) compare patient-reported knee instability, function, and preinjury activity level between patients with non-ACLR and ACLR treatment decisions. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 216 patients with acute ACL injury were evaluated during the first year after injury. The treatment decision was non-ACLR in 73 patients and ACLR in 143. Reasons guiding treatment decision were obtained from medical charts and questionnaires to patients and orthopaedic surgeons. Patient-reported instability and function were obtained via questionnaires and compared between patients with non-ACLR and ACLR treatment decisions. The ACLR treatment group was classified retrospectively by decision phase: acute phase (decision made between injury day and 31 days after injury), subacute phase (decision made between 32 days and up to 5 months after injury), and late phase (decision made 5-12 months after injury). Data were evaluated using descriptive statistics, and group comparisons were made using parametric or nonparametric tests as appropriate. Results: The main reasons for a non-ACLR treatment decision were no knee instability and no problems with knee function. The main reasons for an ACLR treatment decision were high activity demands and knee instability. Patients in the non-ACLR group were significantly older (P = .031) and had a lower preinjury activity level than did those in the acute-phase (P < .01) and subacute-phase (P = .006) ACLR decision groups. There were no differences in patient-reported instability and function between treatment decision groups at baseline, 4 weeks after injury, or 3 months after injury. Conclusion: Activity demands, not patient-reported knee instability, may be the most important factor in the decision-making process for treatment after ACL injury. We suggest a decision-making algorithm for patients with ACL injuries and no high activity demands; waiting for >3 months can help distinguish those who need surgical intervention from those who can undergo nonoperative management.

Abstract
OBJECTIVE To compare 5-year change in femorotibial cartilage thickness in 121 young, active adults with an acute anterior cruciate ligament (ACL) tear randomized to a strategy of structured rehabilitation plus early ACL reconstruction (ACLR) or structured rehabilitation plus optional delayed ACLR. DESIGN 62 patients were randomized to early ACLR, 59 to optional delayed ACLR. Magnetic resonance imaging (MRI) was acquired within 4 weeks of injury, at two- and 5-years follow-up. Main outcome was 5-year change in overall femorotibial cartilage thickness. Secondary outcomes included the location-independent cartilage ChangeScore, summarizing thinning and thickening in 16 femorotibial subregions. An exploratory as-treated comparison was performed additionally. RESULTS Baseline and at least one follow-up MRI were available for 117 patients. Over 5 years, a comparable increase in overall femorotibial cartilage thickness was observed for patients randomized to early ACLR (n = 59) and patients randomized to optional delayed ACLR (n = 58, adjusted mean difference: -5 μm, 95% CI: [-118, 108]μm). However, the location-independent cartilage ChangeScore was greater in those treated with early ACLR than in patients treated with optional delayed ACLR (adjusted mean difference: 403 μm [119, 687]μm). As-treated analysis showed no between-group differences for the main outcome, while the location-independent cartilage ChangeScore was greater for patients treated with early (adjusted mean difference: 632 μm [268, 996]μm) or delayed ACLR (adjusted mean difference: 449 μm [108, 791]μm) than for patients treated with rehabilitation alone. CONCLUSIONS In young active adults with acute ACL-injury, choice of treatment strategy for the injured ACL did not modify the magnitude of 5-year change in overall femorotibial cartilage thickness.

Abstract
OBJECTIVES This study assessed knowledge, beliefs and practices of elite female footballers regarding injury prevention. METHODS A survey was sent to players participating in the FIFA Women's World Cup France 2019. Questions covered three injury prevention domains: (1) knowledge; (2) attitudes and beliefs; (3) prevention practices in domestic clubs. Additionally, ACL injury history was assessed. RESULTS Out of 552 players, 196 women responded (35.5%). More than 80% of these considered injury risk to be moderate or high. Players listed knee, ankle, thigh, head and groin as the most important injuries in women's football. The most important risk factors identified were low muscle strength, followed by poor pitch quality, playing on artificial turf, too much training, reduced recovery and hard tackles. In these elite players, 15% did not have any permanent medical staff in their domestic clubs, yet more than 75% had received injury prevention advice and more than 80% performed injury prevention exercises in their clubs. Players identified the two most important implementation barriers as player motivation and coach attitude. Two-thirds of players used the FIFA 11+ programme in their clubs. CONCLUSIONS This diverse group of elite players demonstrated good knowledge of risk level and injury types in women's football. Of the risk factors emphasised by players, there was only one intrinsic risk factor (strength), but several factors out of their control (pitch quality and type, training volume and hard tackles). Still players had positive attitudes and beliefs regarding injury prevention exercises and indicated a high level of implementation, despite a lack of medical support.

Abstract
BACKGROUND Rupture of the anterior cruciate ligament (ACL) is a common and feared injury among athletes because of its potential effect on further sports participation. Reported rates of return to pivoting sports after ACL reconstruction (ACLR) vary in the literature, and the long-term consequences of returning have rarely been studied. PURPOSE To examine the rate and level of return to pivoting sports after ACLR, the duration of sports participation, and long-term consequences of returning to pivoting sports. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS All primary ACLRs with a bone-patellar tendon-bone autograft between 1987 and 1994 (N = 234) in athletes participating in team handball, basketball, or soccer before injury were selected from a single-center quality database. A long-term evaluation (median, 25 years; range, 22-30 years) was performed using a questionnaire focusing on return to pivoting sports, the duration of sports activity after surgery, later contralateral ACL injuries, revision surgery, and knee replacement surgery. Participants were stratified into 2 groups depending on the time between injury and surgery (early, <24 months; late, ≥24 months). RESULTS A total of 93% of patients (n = 217) responded to the questionnaire. Although 83% of patients returned to pivoting sports after early ACLR, only 53% returned to preinjury level. Similar return-to-sport rates were observed in males and females (P > .05), but males had longer sports careers (median, 10 years; range, 1-23 years) than females (median, 4 years; range, 1-25 years; P < .001). The incidence of contralateral ACL injuries was 28% among athletes who returned to sports versus 4% among athletes who did not return (P = .017) after early ACLR. The pooled reinjury rate after return to preinjury level of sports was 41% (30%, contralateral injuries; 11%, revision surgery). The incidence of contralateral ACL injuries was 32% among females versus 23% among males (P > .05) and, for revision surgery, was 12% among females versus 7% among males (P > .05) after returning to sports. Having a late ACLR was associated with an increased risk of knee replacement surgery (9% vs 3%; P = .049) when compared with having an early ACLR. CONCLUSION ACLR does not necessarily enable a return to preinjury sports participation. By returning to pivoting sports after ACLR, athletes are also facing a high risk of contralateral ACL injuries. Long-term evaluations in risk assessments after ACLR are important, as a significant number of subsequent ACL injuries occur later than the routine follow-up.

Abstract
OBJECTIVES To investigate the association between choice of treatment and patients' income after cruciate ligament (CL) injury and assess the effect of different covariates such as sex, age, comorbidities and type of work. METHODS This entire-population cohort study in Sweden included working patients with a diagnosed CL injury between 2002 and 2005, identified in The National Swedish Patient Register (n = 13,662). The exposure was the treatment choice (operative or non-operative treatment). The main outcome measure was average yearly income five years after CL diagnosis, adjusted for the following covariates: sex, age, comorbidities, type of work, region, calendar year, education and income. RESULTS Relative to non-operative treatment, operative treatment was associated with greater average yearly incomes (nine to 15%) after injury among patients between 20 and 50 years, patients with partial university education, patients living in large cities and patients with one comorbidity, despite no overall significant association in the national cohort. Delayed operative treatment (>1 year) had no significant association with income change, whereas early operative treatment (<1 year) was associated with higher average yearly incomes (11 to 16%) among females, patients between 20 and 50 years, patients living in large cities and patients with one comorbidity. CONCLUSIONS In a broad sense, treatment choice was not associated with changes in income five years after CL injuries among patients in the workforce, however earlier operative treatment was associated with higher average incomes among patients with ages between 20 and 50, females, living in large cities, with one comorbidity and with a high level of education.

Abstract
BACKGROUND An anterior cruciate ligament (ACL) injury is a well-established risk factor for the long-term development of radiographic osteoarthritis (OA). However, little is known about the early degenerative changes (ie, <5 years after injury) of individual joint features (ie, cartilage, bone marrow), which may be reversible and responsive to interventions. PURPOSE To describe early degenerative changes between 1 and 5 years after ACL reconstruction (ACLR) on magnetic resonance imaging (MRI) and explore participant characteristics associated with these changes. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Seventy-eight participants (48 men; median age, 32 years; median body mass index [BMI], 26 kg/m2) underwent 3.0-T MRI at 1 and 5 years after primary hamstring autograft ACLR. Early tibiofemoral and patellofemoral OA features were assessed with the MRI Osteoarthritis Knee Score. The primary outcome was worsening (ie, incident or progressive) cartilage defects, bone marrow lesions (BMLs), osteophytes, and meniscal lesions. Logistic regression with generalized estimating equations evaluated participant characteristics associated with worsening features. RESULTS Worsening of cartilage defects in any compartment occurred in 40 (51%) participants. Specifically, worsening in the patellofemoral and medial and lateral tibiofemoral compartments was present in 34 (44%), 8 (10%), and 10 (13%) participants, respectively. Worsening patellofemoral and medial and lateral tibiofemoral BMLs (14 [18%], 5 [6%], and 10 [13%], respectively) and osteophytes (7 [9%], 8 [10%], and 6 [8%], respectively) were less prevalent, while 17 (22%) displayed deteriorating meniscal lesions. Worsening of at least 1 MRI-detected OA feature, in either the patellofemoral or tibiofemoral compartment, occurred in 53 (68%) participants. Radiographic OA in any compartment was evident in 5 (6%) and 16 (21%) participants at 1 and 5 years, respectively. A high BMI (>25 kg/m2) was consistently associated with elevated odds (between 2- and 5-fold) of worsening patellofemoral and tibiofemoral OA features. CONCLUSION High rates of degenerative changes occur in the first 5 years after ACLR, particularly the development and progression of patellofemoral cartilage defects. Older patients with a higher BMI may be at particular risk and should be educated about this risk.

Abstract
PURPOSE The purpose of the study was to (1) study and compare the factors that Swedish orthopaedic surgeons and physical therapists consider important for recommending ACL reconstruction and, (2) to assess how orthopaedic surgeons and physical therapists consider their own and each others, as well as patients', roles are in the treatment decision. METHODS A web-based survey assessing the relevance of 21 predetermined factors, in the choice to recommend ACL reconstruction, was sent to orthopaedic surgeons and physical therapists. Respondents were also asked to rate the importance of the assessment made by themselves, the other clinician (physical therapists rated the importance of surgeons, surgeons rated the importance of physical therapists), and the patients' preferences. RESULT Orthopaedic surgeons agreed of eight, and physical therapists of seven factors as important in the choice to recommend ACL reconstruction. The factors both groups reported as important were; "patient's wishes to return to contact/pivoting sports", "instability in physical activity", "instability in activities of daily living despite adequate rehabilitation", "physically demanding occupation", and "young age". Both professions rated their own and each others assessments as well as patient's wishes as important for the decision to recommend ACL reconstruction. CONCLUSION Orthopaedic surgeons and physical therapists agree about factors that are important for their decision to recommend ACL reconstruction, showing that both professions share a common ground in perceptions of factors that are important in recommending ACL reconstruction. LEVEL OF EVIDENCE Diagnostic study: Level III.

Abstract
Context: Female athletes aged 14 to 18 years are at particular risk for anterior cruciate ligament (ACL) injuries. Hormonal factors are thought to predispose them to this injury. Oral contraceptive pills (OCPs) might reduce ACL injury risk, although the literature appears controversial. Objective: To evaluate the association between OCP use and ACL injuries in women. The secondary objective was to determine the rates of ACL injuries in the pre- and postovulatory phases of the menstrual cycle in OCP and non-OCP (NOCP) users. Data Sources: Searches were performed across 4 reference databases (PubMed, CINAHL, Embase, Cochrane), abstracts from 6 specialty societies, ClinicalTrials.gov, and reference lists of relevant papers. Study Selection: We included studies investigating the association between OCP use and ACL injuries in females of any age or the distribution of ACL injuries across the menstrual cycle in OCP and NOCP users. Study Design: Systematic review. Level of Evidence: Level 3. Data Extraction: Data regarding study design, population characteristics, OCP details, outcome definitions, analytic methods, and results were extracted from the included studies. The methodological quality of each study was assessed using the Newcastle-Ottawa scale. Results: The search yielded 1305 citations, of which 7 retrospective observational studies met the inclusion criteria. Two large case-control studies with higher methodological quality suggested that OCP use may reduce the risk of sustaining an ACL injury. Five comparative studies examining injury distribution across the menstrual cycle in OCP and NOCP users had conflicting findings, were heterogeneous, and were limited by low methodological quality. Conclusion: The evidence suggests OCP use may reduce the risk of ACL injury; however, no conclusions can be drawn regarding differences in risk of ACL injuries between OCP and NOCP users across the menstrual cycle. Studies were limited by small sample sizes, heterogeneity, and methodological concerns.

Abstract
PURPOSE The purpose of this study is to compare the clinical outcome of ACL reconstructions in patients older than 40 years of age to younger subjects. It has been hypothesized that patients older than 40 years of age achieve comparable clinical outcomes following acute ACL reconstruction using a hamstring tendon autograft than younger patients. METHODS Patients with an isolated ACL tear without any concomitant injuries and subsequent ACL reconstruction within 48 h from injury were included in this prospective study. According to patients' age, subjects were assigned to two groups: (A) 18-40 years and (B) 40-60 years. Functional outcomes, pain, post-operative radiographs and return to sports were recorded and analysed. The follow-up period was 24 months. RESULTS A total of 59 patients were included in the study. Group A consisted of 39 patients (14 women, 25 men; median 27 years), group B of 20 patients (12 women, 8 men; median 45 years) respectively. At final follow-up, the Lysholm score showed no significant difference between group A (median 90; range 68-100) and group B (median 94.5; range 63-100) (n.s.). The final Tegner score showed a significant difference between group A (median 6; range 2-9) and group B (median 5.5; range 3-8) (p < 0.05). The mean VAS pain score was 1.3 (range 0-6) in group A and 1 (range 0-7) in group B, respectively (n.s.). Both groups returned to their pre-injury activity level and did not significantly change their activity in respect of pivoting sports and sports frequency at final follow-up (n.s.). According to the IKDC score, all except one of the patients in group A and all patients in group B had a normal or nearly normal final outcome (n.s.). CONCLUSION Patients older than 40 years of age achieve comparable clinical outcomes following acute ACL reconstruction using a hamstring tendon autograft than younger patients. LEVEL OF EVIDENCE Cohort study, Level III.

Abstract
BACKGROUND The socioeconomic status (SES) of patients has been widely recognized as playing an important role in many health-related conditions, including orthopaedic conditions, in which a higher SES has been associated with a higher utilization of more advanced medical treatments such as drugs, diagnostics, and surgery. However, the association between SES and cruciate ligament surgery has not been thoroughly investigated. PURPOSE To evaluate the association between SES and choice of treatment in patients with a cruciate ligament injury. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All Swedish patients with a diagnosed cruciate ligament injury between 1987 and 2010 were identified from the Swedish National Patient Register (N = 98,349). The Longitudinal Integration Database for Health Insurance and Labor Market Studies (LISA) provided information on household income and highest achieved educational level, which were used as socioeconomic indices. The exposure was the SES of patients as determined by the household income and educational level, and the main outcome measure was treatment choice (surgical reconstruction vs nonoperative treatment). Poisson regression models estimated the association. RESULTS A total of 52,566 patients were included in the study; of these, 20,660 (39%) were treated operatively. Patients in the highest quartile of household income had a significantly higher likelihood of undergoing surgery than those in the lowest quartile (relative risk [RR], 1.16; 95% CI, 1.11-1.20). Patients classified as highly educated had a significantly increased likelihood of being treated operatively compared with those with a low education (RR, 1.29; 95% CI, 1.19-1.39). CONCLUSION This study provides a population-based validation that having a higher SES as determined by the household income and/or level of education increases the likelihood of undergoing operative treatment after a cruciate ligament injury. CLINICAL RELEVANCE All Swedish citizens are entitled by law to the same quality of health care; therefore, unmotivated differences in treatment between different socioeconomic groups are to be seen as a challenge. It is important to evaluate the specific mechanisms by which the patient's SES influences the decision of whether to treat a cruciate ligament injury operatively.

Abstract
BACKGROUND The time between an anterior cruciate ligament (ACL) injury and ACL reconstruction (ACLR) may influence baseline knee-related and general health-related patient-reported outcome measures (PROMs). Despite the common use of PROMs as main outcomes in clinical studies, this variable has never been evaluated. PURPOSE To compare baseline health-related quality of life measures and the prevalence/pattern of meniscal and articular cartilage lesions between patients who underwent acute and chronic ACLR so as to provide clinicians with benchmark PROMs in 2 different patient populations with ACL injuries. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS A total of 1192 patients from the MOON (Multicenter Orthopaedic Outcomes Network) cohort who underwent primary ACLR were eligible. "Acute" ACLR was defined as <3 months (n = 853; 71.6%) and "chronic" ACLR as >6 months (n = 339; 28.4%) from injury. Patient demographics, surgical characteristics (articular cartilage injury, medial meniscal [MM] and lateral meniscal [LM] tears), and baseline PROM scores (Marx activity rating scale, International Knee Documentation Committee [IKDC] subjective form, Knee injury and Osteoarthritis Outcome Score [KOOS], and Short Form-36 Health Survey [SF-36]) were collected to determine whether the time from injury to ACLR influences (1) baseline PROMs and (2) the pattern and prevalence of concurrent articular cartilage and meniscal injuries. Analysis of covariance models were used to adjust for confounders on baseline outcome scores (age, sex, body mass index [BMI], smoking status, competition level, education). RESULTS The median patient age was 23 years (interquartile range [IQR], 17-35 years), 530 (44.5%) were female, and the median BMI was 25.0 kg/m2 (IQR, 22.3-27.9 kg/m2); however, the chronic group was older, had a higher BMI, and consisted of fewer collegiate athletes. A significantly greater number of partial LM tears were seen in the acute group versus the chronic group (14.2% vs 6.5%, respectively; P < .001), but there were more meniscal tears overall (73.5% vs 63.2%, respectively; P = .001), complete MM tears (49.0% vs 22.5%, respectively; P < .001), and articular cartilage injuries (54.0% vs 32.8%, respectively; P < .001) in the chronic group versus the acute group. After controlling for confounders, patients in the chronic ACLR group reported a significantly lower baseline Marx score (7.75 vs 12.10, respectively; P < .001) but higher baseline IKDC, SF-36 physical functioning, and all KOOS subscale scores except the KOOS-quality of life subscale score compared to those in the acute ACLR group; however, only the KOOS-sports and recreation subscale exceeded the minimum clinically importance difference of 8 points (62.30 vs 48.26, respectively; P < .001). CONCLUSION After controlling for age, sex, competition level, smoking, and BMI, patients in the chronic ACLR group participated in less pivoting and cutting sports but reported better pain/function. Whether decreased activity is deliberate after an ACL injury or patients who undergo chronic ACLR are simply less active and may be treated successfully without surgery warrants further investigation. Nonrandomized studies that utilize PROMs should consider time from injury in study design and data interpretation.

Abstract
ObjectivesThe primary objective was to calculate the rate of return to sport (RTS) following anterior cruciate ligament (ACL) reconstruction in elite athletes. Secondary objectives were to estimate the time taken to RTS, calculate rates of ACL graft rupture, evaluate postsurgical athletic performance and identify determinants of RTS.DesignPooled RTS and graft rupture rates were calculated using random effects proportion meta-analysis. Time to RTS, performance data and determinants of RTS were synthesised descriptively.Data sourcesMEDLINE, EMBASE, AMED, CINAHL, AMI, PEDro, SPORTDiscus and The Cochrane Library were searched from inception to 19 January 2016. Hand searching of 10 sports medicine journals and reference checking were also performed.Eligibility criteria for selecting studiesStudies were included if they reported the ratio of elite athletes who returned to their preinjury level of sport following ACL reconstruction. Twenty-four studies were included.ResultsThe pooled RTS rate was 83% (95% CI 77% to 88%). The mean time to RTS ranged from 6 to 13 months. The pooled graft rupture rate was 5.2% (95% CI 2.8% to 8.3%). Six out of nine studies that included a noninjured control group found no significant deterioration in athletic performance following ACL reconstruction. Indicators of greater athletic skill or value to the team were associated with RTS.Summary and conclusionsEighty-three per cent of elite athletes returned to sport following ACL reconstruction, while 5.2% sustained a graft rupture. Most athletes who returned to sport performed comparably with matched, uninjured controls. This information may assist in guiding expectations of athletes and clinicians following ACL reconstruction.

Abstract
INTRODUCTION/PURPOSE Anterior cruciate ligament injuries often incur major consequences for athletes. Elevated estrogen levels are likely increase the risk for injury. This risk may be partially or fully mitigated by the use of oral contraceptives. The purpose of this study was to determine if women undergoing anterior cruciate ligament surgical reconstruction were less likely to use oral contraceptives than matched noninjured population. METHODS This is a case-control study utilizing national insurance claims data from 2002 TO 2012. Participants included women age 15-39 yr. Cases were defined as those receiving surgical reconstruction of the anterior cruciate ligament between 2002 and 2012. Controls were matched 3/1 to cases. Exposure to oral contraceptives was defined as the presence of any prescription fill for oral contraceptives during the previous 12 months to index date. Conditional multivariate logistic regression was used to estimate adjusted odds ratios for the use of oral contraceptives. RESULTS Women age 15-19 yr undergoing surgical repair of the anterior cruciate ligament were 18% less likely to use oral contraceptives than matched controls (adjusted odds ratio, 0.82; 95% CI, 0.75-0.91; P < 0.0001). Cases among two older age groups, 25-29 and 30-34 yr, were more likely to use oral contraceptives than controls with adjusted odds ratios of 1.15 (95% CI, 1.02-1.30; P < 0.05) and 1.16 (95% CI, 1.04-1.31; P < 0.05), respectively. CONCLUSIONS The use of oral contraceptives potentially modifies anterior cruciate ligament injury risk in young women. Despite reports that athletes, who are more prone to anterior cruciate ligament injury, use oral contraceptives at about twice the rate of nonathletes, these data suggest that women ages 15-19 yr undergoing anterior cruciate ligament reconstruction used oral contraceptives at a lower rate than the general population.

Abstract
The aim of our study was to cross-sectionally compare patient-reported knee function outcomes between people who chose non-surgical treatment for ACL injury and those who chose ACL reconstruction. We extracted Knee Injury and Osteoarthritis Outcome Score (KOOS) and EuroQoL-5D data entered into the Swedish National ACL Registry by patients with a non-surgically treated ACL injury within 180 days of injury (n = 306), 1 (n = 350), 2 (n = 358), and 5 years (n = 114) after injury. These data were compared cross-sectionally to data collected pre-operatively (n = 306) and at 1 (n = 350), 2 (n = 358), and 5 years (n = 114) post-operatively from age- and gender-matched groups of patients with primary ACL reconstruction. At the 1 and 2 year comparisons, patients who chose surgical treatment reported superior quality of life and function in sports (1 year mean difference 12.4 and 13.2 points, respectively; 2 year mean difference 4.5 and 6.9 points, respectively) compared to those who chose non-surgical treatment. Patients who chose ACL reconstruction reported superior outcomes for knee symptoms and function, and in knee-specific and health-related quality of life, compared to patients who chose non-surgical treatment.

Abstract
Six degree of freedom (6-DOF) robotic manipulators have simulated clinical tests and gait on cadaveric knees to examine knee biomechanics. However, these activities do not necessarily emulate the kinematics and kinetics that lead to anterior cruciate ligament (ACL) rupture. The purpose of this study was to determine the techniques needed to derive reproducible, in vitro simulations from in vivo skin-marker kinematics recorded during simulated athletic tasks. Input of raw, in vivo, skin-marker-derived motion capture kinematics consistently resulted in specimen failure. The protocol described in this study developed an in-depth methodology to adapt in vivo kinematic recordings into 6-DOF knee motion simulations for drop vertical jumps and sidestep cutting. Our simulation method repeatably produced kinetics consistent with vertical ground reaction patterns while preserving specimen integrity. Athletic task simulation represents an advancement that allows investigators to examine ACL-intact and graft biomechanics during motions that generate greater kinetics, and the athletic tasks are more representative of documented cases of ligament rupture. Establishment of baseline functional mechanics within the knee joint during athletic tasks will serve to advance the prevention, repair and rehabilitation of ACL injuries.

Abstract
BACKGROUND Fear of reinjury and lack of confidence influence return-to-sport outcomes after anterior cruciate ligament (ACL) reconstruction. The physical, psychosocial, and functional recovery of patients reporting fear of reinjury or lack of confidence as their primary barrier to resuming sports participation is unknown. PURPOSE To compare physical impairment, functional, and psychosocial measures between subgroups based on return-to-sport status and fear of reinjury/lack of confidence in the return-to-sport stage and to determine the association of physical impairment and psychosocial measures with function for each subgroup at 6 months and 1 year after surgery. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS Physical impairment (quadriceps index [QI], quadriceps strength/body weight [QSBW], hamstring:quadriceps strength ratio [HQ ratio], pain intensity), self-report of function (International Knee Documentation Committee [IKDC]), and psychosocial (Tampa Scale for Kinesiophobia-shortened form [TSK-11]) measures were collected at 6 months and 1 year after surgery in 73 patients with ACL reconstruction. At 1 year, subjects were divided into "return-to-sport" (YRTS) or "not return-to-sport" (NRTS) subgroups based on their self-reported return to preinjury sport status. Patients in the NRTS subgroup were subcategorized as NRTS-Fear/Confidence if fear of reinjury/lack of confidence was the primary reason for not returning to sports, and all others were categorized as NRTS-Other. RESULTS A total of 46 subjects were assigned to YRTS, 13 to NRTS-Other, and 14 to NRTS-Fear/Confidence. Compared with the YRTS subgroup, the NRTS-Fear/Confidence subgroup was older and had lower QSBW, lower IKDC score, and higher TSK-11 score at 6 months and 1 year; however, they had similar pain levels. In the NRTS-Fear/Confidence subgroup, the IKDC score was associated with QSBW and pain at 6 months and QSBW, QI, pain, and TSK-11 scores at 1 year. CONCLUSION Elevated pain-related fear of movement/reinjury, quadriceps weakness, and reduced IKDC score distinguish patients who are unable to return to preinjury sports participation because of fear of reinjury/lack of confidence. Despite low average pain ratings, fear of pain may influence function in this subgroup. Assessment of fear of reinjury, quadriceps strength, and self-reported function at 6 months may help identify patients at risk for not returning to sports at 1 year and should be considered for inclusion in return-to-sport guidelines.

Abstract
Objective To study the association between Cruciate Ligament (CL) injury and development of post-traumatic osteoarthritis in the knee in patients treated operatively with CL reconstruction compared with patients treated non-operatively. Design Population based cohort study; level of evidence II-2. Setting Sweden, 1987–2009. Participants All patients aged between 15–60 years being diagnosed and registered with a CL injury in The National Swedish Patient Register between 1987 and 2009. Main Outcome Measures Knee osteoarthritis. Results A total of 64,614 patients diagnosed with CL injury during 1987 to 2009 in Sweden were included in the study. Seven percent of the patients were diagnosed with knee OA in specialized healthcare during the follow-up (mean 9 years). Stratified analysis by follow-up showed that while those with shorter follow-up had a non-significant difference in risk (0.99, 95%CI 0.90–1.09 for follow-up less than five years compared with the non-operated cohort), those with longer follow-up had an increased risk of knee OA after CL reconstruction (HR = 1.42, 95%CI 1.27–1.58 for follow-up more than ten years compared with non-operated cohort). The risk to develop OA was not affected by sex. Conclusion CL reconstructive surgery does not seem to have a protective effect on long term OA in either men or women.

The effects of high-intensity versus low-intensity resistance training on leg extensor power and recovery of knee function after ACL-reconstruction. BIOMED RESEARCH INTERNATIONAL 2014; 2014:278512. [PMID: 24877078 PMCID: PMC4022205 DOI: 10.1155/2014/278512] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/21/2014] [Revised: 03/24/2014] [Accepted: 03/28/2014] [Indexed: 01/27/2023]
Abstract
Objective. Persistent weakness is a common problem after anterior cruciate ligament- (ACL-) reconstruction. This study investigated the effects of high-intensity (HRT) versus low-intensity (LRT) resistance training on leg extensor power and recovery of knee function after ACL-reconstruction. Methods. 31 males and 19 females were randomized to HRT (n = 24) or LRT (n = 26) from week 8–20 after ACL-reconstruction. Leg extensor power, joint laxity, and self-reported knee function were measured before and 7, 14, and 20 weeks after surgery. Hop tests were assessed before and after 20 weeks. Results. Power in the injured leg was 90% (95% CI 86–94%) of the noninjured leg, decreasing to 64% (95% CI 60–69%) 7 weeks after surgery. During the resistance training phase there was a significant group by time interaction for power (P = 0.020). Power was regained more with HRT compared to LRT at week 14 (84% versus 73% of noninjured leg, resp.; P = 0.027) and at week 20 (98% versus 83% of noninjured leg, resp.; P = 0.006) without adverse effects on joint laxity. No other between-group differences were found. Conclusion. High-intensity resistance training during rehabilitation after ACL-reconstruction can improve muscle power without adverse effects on joint laxity.

Abstract
STUDY DESIGN Phenomenographic, cross-sectional. OBJECTIVES To describe ways of experiencing participation in activities of individuals with a nonreconstructed anterior cruciate ligament injury and to describe the emotional aspects related to participation. Further, the objective was to explore factors affecting the activity level. BACKGROUND The importance of assessing different factors (knee status, muscle performance, psychological factors, performance-based tests, and subjective rating of knee function) after an anterior cruciate ligament injury has been emphasized. However, the results of these assessments do not answer the question of how the individuals themselves experience their participation in activities. METHODS Semi-structured interviews were conducted with 19 strategically selected informants (age range, 18-43 years) who had sustained an anterior cruciate ligament injury 18 to 67 months previously. A phenomenographic approach, which describes individuals' ways of experiencing a phenomenon, was used. RESULTS Five qualitatively different categories were identified: (A) unconditioned participation, (B) participation as conditioned by risk appraisal, (C) participation as conditioned by experienced control of the knee, (D) participation as conditioned by experienced knee impairment, and (E) participation as conditioned by neglecting the knee injury. Within each category, 5 interrelated aspects were discerned: focus, level of performance, activities, strategies, and feelings. Categories A, C, and E reflected experiences of full participation, whereas categories B and D reflected experiences of modified participation. There were mostly positive feelings regarding participation. Negative feelings were expressed in category D. Factors affecting the activity level were grouped according to the framework of the International Classification of Functioning, Disability and Health and described as facilitating or hindering the activity level. Facilitating factors included regaining and maintaining physical function, regaining confidence in knee function, and learning/relearning movement patterns. Hindering factors included fear of injury/reinjury, uncontrollable giving way, and loss of motivation. CONCLUSION With different strategies, most of the informants achieved a satisfactory activity level, despite impairments and decreased activity level. Both physical and psychological factors were described to affect the activity level, as well as time since injury.

Abstract
BACKGROUND A few national cruciate ligament (CL) registers have been initiated with operative surveillance and outcome monitoring. No nationwide study describing CL injury has ever been done. PURPOSE To study the incidence and characteristics of patients diagnosed with cruciate ligament injury in Sweden. STUDY DESIGN Descriptive epidemiology study. METHODS Data for all patients with a diagnosed CL injury between 2001 and 2009 were identified from the National Swedish Patient Register. Risk analysis and specific incidences were calculated according to age, sex, geographic region, and surgery. RESULTS A total number of 56,659 patients with CL injury were included in the study, and the overall incidence of CL injury in Sweden was 78 per 100,000 persons. Sixty percent of the patients were male. The mean age was 32 years (range, 1-98 years), and 50% of the cohort was younger than 30 years. There was an increased rate of injury among female patients younger than 20 years as compared with male patients in that age group. Among patients with CL injury, 36% underwent reconstructive surgery, with one-third of these performed within 1 year after injury. Among patients who underwent surgery, 59% were male; the mean age was 27 years (range, 5-89 years). CONCLUSION This study defines the incidence of CL injury and also demonstrates sex differences in which men were more likely to sustain a CL injury, although female patients were injured at an earlier age. The findings in this study corroborate the results from recent surgical registers. CLINICAL RELEVANCE No data have hitherto been published including all patients with CL injury, treated both surgically and nonsurgically. Such baseline epidemiologic data are crucial to be able to validate and judge the generalizability of results from procedure registers and clinical studies.

Abstract
PURPOSE Is it rational to recommend surgical reconstruction of the torn anterior cruciate ligament to every patient? Is conservative management still a valid option? METHOD Through a literature review, we looked for the arguments from each side and checked their validity. RESULTS Unfortunately results of most studies cannot be compared because of the following reasons not exhaustively cited: studied populations differed with respect to age, sex, professional and sports activity level, lesions associated with ACL rupture, patient recruitment methods, time from injury to treatment and different therapeutic modalities. Furthermore, various methods were used to evaluate the clinical and radiological results and there was no consensus of their interpretation. Some authors assumed that the incidence of further meniscus lesions could probably be reduced if the torn ACL was surgically reconstructed. But, we have no evidence to believe that this would be due to the surgical repair rather than to a decrease of involvement in strenuous activities. At present it is not demonstrated that ACL-plasty can prevent osteoarthritis. Numerous factors could explain evolution to arthrosis whatever the treatment for the ACL-ruptured knee. Studies comparing surgical and conservative treatments confirm that ACL reconstruction is not the pre-requisite for returning to sporting activities. More recent and scientifically well-designed studies demonstrate that conservative treatment could give satisfactory results for many patients. They suggest some methods to help them choose the best treatment. CONCLUSION At present there are no evidence-based arguments to recommend a systematic surgical reconstruction to any patient who tore his ACL. Knee stability can be improved not only by surgery but also by neuromuscular rehabilitation. Whatever the treatment, fully normal knee kinematics are not restored. While the patients wish to go back to their sport and want everything possible done to prolong their ability to perform these activities, they should be informed that the risk of further knee lesions and osteoarthritis remains high, whatever the treatment, surgical or conservative. LEVEL OF EVIDENCE Systematic review of Level I, II, III and IV studies, Level IV.

Abstract
STUDY DESIGN Cross-sectional cohort. OBJECTIVES (1) To examine differences in clinical variables (demographics, knee impairments, and self-report measures) between those who return to preinjury level of sports participation and those who do not at 1 year following anterior cruciate ligament reconstruction, (2) to determine the factors most strongly associated with return-to-sport status in a multivariate model, and (3) to explore the discriminatory value of clinical variables associated with return to sport at 1 year postsurgery. BACKGROUND Demographic, physical impairment, and psychosocial factors individually prohibit return to preinjury levels of sports participation. However, it is unknown which combination of factors contributes to sports participation status. METHODS Ninety-four patients (60 men; mean age, 22.4 years) 1 year post-anterior cruciate ligament reconstruction were included. Clinical variables were collected and included demographics, knee impairment measures, and self-report questionnaire responses. Patients were divided into "yes return to sports" or "no return to sports" groups based on their answer to the question, "Have you returned to the same level of sports as before your injury?" Group differences in demographics, knee impairments, and self-report questionnaire responses were analyzed. Discriminant function analysis determined the strongest predictors of group classification. Receiver-operating-characteristic curves determined the discriminatory accuracy of the identified clinical variables. RESULTS Fifty-two of 94 patients (55%) reported yes return to sports. Patients reporting return to preinjury levels of sports participation were more likely to have had less knee joint effusion, fewer episodes of knee instability, lower knee pain intensity, higher quadriceps peak torque-body weight ratio, higher score on the International Knee Documentation Committee Subjective Knee Evaluation Form, and lower levels of kinesiophobia. Knee joint effusion, episodes of knee instability, and score on the International Knee Documentation Committee Subjective Knee Evaluation Form were identified as the factors most strongly associated with self-reported return-to-sport status. The highest positive likelihood ratio for the yes-return-to-sports group classification (14.54) was achieved when patients met all of the following criteria: no knee effusion, no episodes of instability, and International Knee Documentation Committee Subjective Knee Evaluation Form score greater than 93. CONCLUSION In multivariate analysis, the factors most strongly associated with return-to-sport status included only self-reported knee function, episodes of knee instability, and knee joint effusion.

Abstract
PURPOSE To evaluate in vivo the differences in tibial rotation between single- and double-bundle anterior cruciate ligament (ACL)-reconstructed knees under combined loading conditions. METHODS An 8-camera optoelectronic system and a force plate were used to collect kinematic and kinetic data from 14 patients with double-bundle ACL reconstruction, 14 patients with single-bundle reconstruction, 12 ACL-deficient subjects, and 12 healthy control individuals while performing 2 tasks. The first included walking, 60° pivoting, and stair ascending, and the second included stair descending, 60° pivoting, and walking. The 2 variables evaluated were the maximum range of internal-external tibial rotation and the maximum knee rotational moment. RESULTS Tibial rotation angles were not significantly different across the 4 groups (P = .331 and P = .851, respectively) or when side-to-side differences were compared within groups (P = .216 and P = .371, respectively) for the ascending and descending maneuvers, nor were rotational moments among the 4 groups (P = .418 and P = .290, respectively). Similarly, for the descending maneuver, the rotational moments were not significantly different between sides (P = .192). However, for the ascending maneuver, rotational moments of the affected sides were significantly lower by 20.5% and 18.7% compared with their intact counterparts in the single-bundle (P = .015) and double-bundle (P = .05) groups, respectively. CONCLUSIONS High-intensity activities combining stair ascending or descending with pivoting produce similar tibial rotation in single- and double-bundle ACL-reconstructed patients. During such maneuvers, the reconstructed knee may be subjected to significantly lower rotational loads compared with the intact knee. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Knee Surg Sports Traumatol Arthrosc 2010; 18:1517-25.

Abstract
A high pre-injury activity level, the desire of the patient to continue pivoting sports and fear of future give-way episodes are considered the most significant factors affecting the decision to perform anterior cruciate ligament reconstruction. However, since the functional status of the knee at the time of surgery affects the final outcome, assessments of knee function should be considered in the decision making for surgery. Individuals with anterior cruciate ligament injury can be classified as potential copers or non-copers from an existing screening examination. The purpose of this study was to investigate whether the functional tests incorporated in the original screening examination could contribute to explain those who later go through anterior cruciate ligament reconstruction and to examine whether changes to the content or the time of conducting the screening examination (before or after ten sessions of exercise therapy) could improve its explanatory value. One-hundred and forty-five individuals were included and prospectively followed for 15 months, after where 51% had gone through anterior cruciate ligament reconstruction and 49% were managed non-operatively. The only significant baseline differences between those who later went through anterior cruciate ligament reconstruction and those who were non-operatively treated were that those who had surgery were younger and had a higher activity level (P < 0.05). Regression analyses revealed that the explanatory value for those who later went through anterior cruciate ligament reconstruction significantly improved when the original screening examination was considered compared to only age, activity level and give-way episodes. Changes to the content further improved the explanatory value, with quadriceps muscle strength as the single variable with the highest impact. Finally, conducting the screening examination after ten sessions of progressive exercise therapy gave the overall highest explanatory values, suggesting that the screening examination should be conducted subsequent to a short period of rehabilitation to inform decision making for anterior cruciate ligament reconstruction.

Abstract
BACKGROUND Abnormal 3-dimensional tibiofemoral joint kinematics have been identified in anterior cruciate ligament-reconstructed knees during functional gait tasks, which is suggested to directly affect risk of knee osteoarthritis. However, the extent to which similar high-risk abnormalities are present during more demanding maneuvers, such as single-legged hopping, is largely unknown. HYPOTHESIS When performing a single-legged forward hop landing, the reconstructed knee will demonstrate altered sagittal, frontal, and transverse plane kinematics compared with the contralateral limb. STUDY DESIGN Controlled laboratory study. METHODS High-speed biplane radiography was used to quantify bilateral 3-dimensional tibiofemoral joint kinematics in 9 subjects with unilaterally reconstructed anterior cruciate ligaments (mean time after surgery, 4 months) during 3 single-legged, forward hop landing trials. Mean subject-based initial foot contact and maximum stance (0-250 ms) values were calculated for each kinematic variable. Two-tailed paired t tests were subsequently applied to examine for the main effect of limb (reconstructed vs contralateral). RESULTS The reconstructed knees exhibited significantly greater extension (P = .04), external tibial rotation (P = .006), and medial tibial translation (P = .02) than the contralateral knees at initial contact. Reconstructed knees underwent significantly greater maximum flexion (P = .05), maximum external tibial rotation (P = .01), and maximum anterior tibial translation (P = .02). No significant differences existed between limbs for initial contact (P = .65) or maximum adduction-abduction (P = .55). CONCLUSION Tibiofemoral joint kinematics of the anterior cruciate ligament-reconstructed knee are significantly different from those of the uninjured contralateral limb during a single-legged hop landing. This altered kinematic profile, in conjunction with the large impact loads associated with hopping, may further contribute to the risk of posttraumatic knee osteoarthritis. CLINICAL RELEVANCE Returning to sports involving dynamic single-legged landings at 4 months after anterior cruciate ligament reconstruction surgery may contribute to accelerated knee joint degeneration.

Abstract
BACKGROUND The optimal management of a torn anterior cruciate ligament (ACL) of the knee is unknown. METHODS We conducted a randomized, controlled trial involving 121 young, active adults with acute ACL injury in which we compared two strategies: structured rehabilitation plus early ACL reconstruction and structured rehabilitation with the option of later ACL reconstruction if needed. The primary outcome was the change from baseline to 2 years in the average score on four subscales of the Knee Injury and Osteoarthritis Outcome Score (KOOS)--pain, symptoms, function in sports and recreation, and knee-related quality of life (KOOS(4); range of scores, 0 [worst] to 100 [best]). Secondary outcomes included results on all five KOOS subscales, the Medical Outcomes Study 36-Item Short-Form Health Survey, and the score on the Tegner Activity Scale. RESULTS Of 62 subjects assigned to rehabilitation plus early ACL reconstruction, 1 did not undergo surgery. Of 59 assigned to rehabilitation plus optional delayed ACL reconstruction, 23 underwent delayed ACL reconstruction; the other 36 underwent rehabilitation alone. The absolute change in the mean KOOS(4) score from baseline to 2 years was 39.2 points for those assigned to rehabilitation plus early ACL reconstruction and 39.4 for those assigned to rehabilitation plus optional delayed reconstruction (absolute between-group difference, 0.2 points; 95% confidence interval, -6.5 to 6.8; P=0.96 after adjustment for the baseline score). There were no significant differences between the two treatment groups with respect to secondary outcomes. Adverse events were common in both groups. The results were similar when the data were analyzed according to the treatment actually received. CONCLUSIONS In young, active adults with acute ACL tears, a strategy of rehabilitation plus early ACL reconstruction was not superior to a strategy of rehabilitation plus optional delayed ACL reconstruction. The latter strategy substantially reduced the frequency of surgical reconstructions.

Abstract
INTRODUCTION Anterior cruciate ligament reconstruction is an increasingly established method even in patients over 40 years old. Recent studies with regard to this procedure used BTB transplants. We did a retrospective follow-up examination on over-40-year-old patients with anterior cruciate ligament reconstruction using hamstring transplants and compared them to a younger control group. Our hypothesis is that functional outcome after ACL-reconstruction is comparable in patients under and over 40 years of age. MATERIALS AND METHODS Retrospective follow-up examinations in 28 patients, 11 women and 17 men. The average age at the time of operation was 43.5 years (range 40-61). The average follow-up period was 30.4 months. Half of the patients had a femoral fixation in TransFix technique (Arthrex, Naples, USA), while the other 14 patients had a femoral bioscrew fixation (Arthrex, Naples, USA). Objectivity was ensured by measurements of anterior tibial translation with the rolimeter (Aircast). The functional outcome was determined by clinical scores (Tegner activity scale, Lysholm knee score, OAK score and IKDC score). The degree of arthrosis was defined on the basis of tunnelview radiographs and compared to the non-operated site. Functional results and degree of laxity was compared to a sex matched control group (mean age 28.0). RESULTS The median values for the Lysholm knee score were 91.5 points (range 69-100), for the OAK score 93.5 points (range 67-100) and for the IKDC score 83.35 points (range 62.1-100). For the Tegner activity scale values of 4.5 points (range 3-8) were obtained. In the IKDC knee examination form we found normal and nearly normal values in 86% and in the OAK examination score good and very good results in 82%. Ninety-three percent had an AP side-to-side difference of <5 mm in the operated knee. Subjectively, 75% reported that they had no feeling of instability, even when practising sport. No significant correlation between functional outcome and patients' age was present. Furthermore there were no significant differences between the investigated and the younger control group. The most advanced signs of arthrosis were found in the medial compartment of the operated side (degree A: 36%; degree B: 46%; degree C: 14%; degree D: 4%). CONCLUSION The predominantly good results and a high level of patient satisfaction show that anterior cruciate ligament reconstruction is justified even in over-40-year-old patients with persistend subjective symptomatic anterior knee instability. The indication for reconstruction should be based on individual factors such as level of activity or subjective feeling of instability rather than on a dogmatic age limit. Advanced arthrotic changes compared to the healthy side, might be due to a too long period of preoperative decision making.
