Abstract
BACKGROUND Long-term outcomes for isolated anterior cruciate ligament (ACL) reconstructions in competitive American football athletes are well reported in the literature, but little data currently exist regarding multiligament knee injury (MLKI) reconstruction outcomes. PURPOSE To examine patient-reported and return-to-sport outcomes of competitive American football athletes who underwent primary, single-staged, multiligament knee reconstruction. STUDY DESIGN Case series; Level of evidence, 4. METHODS We identified patients from our institution's prospectively collected data repository between 2001 and 2020 who underwent single-staged surgical reconstruction of an MLKI sustained during competitive participation in American football. We assessed patient-reported outcomes at a minimum of 2 years after surgery using the International Knee Documentation Committee (IKDC) Subjective Knee Form and questions regarding surgical satisfaction and return to sport. Successful return to sport was defined as a return to preinjury level of competition. We summarized all outcome data and compared outcomes between 2-ligament and >2-ligament groups and between ACL-only MLKI injury and bicruciate MLKI injury groups using independent t test for IKDC scores and chi-square test for return to sport. Additionally, we evaluated predictors of postoperative IKDC scores using linear regression and predictors of return to sport using logistic regression. RESULTS Outcome data were successfully collected for 53 of 73 total eligible patients (73%; mean follow-up time, 7.7 ± 4.0 years; all male; mean age at surgery, 18.1 ± 2.7 years). The mean postoperative IKDC score was 84 ± 16. The most common level of preinjury competition was high school (n = 36; 68%), followed by college (n = 10; 19%). Seven patients did not return to sport competition at any level due to limitations from their knee surgery, and 82% of patients that attempted to return to preinjury level of sport were able to do so. A total of 50 patients (94%) were satisfied or very satisfied with their surgical outcome. The 2-ligament (n = 39) and >2-ligament (n = 14) groups did not significantly differ in IKDC scores (P = .96) or proportions with successful return to sport (P = .77). Similarly, the ACL-MLKI injury (n = 39) and bicruciate MLKI injury (n = 14) groups did not significantly differ in IKDC scores (P = .89) or proportions with successful return to sport (P = .77). Age and body mass index were not significantly associated with IKDC scores or successful return to sport at follow-up (all P > .05). CONCLUSION This study may represent the largest cohort of competitive American football athletes evaluated for longitudinal outcomes after multiligament knee reconstruction. Despite the severity of these injuries, we found good knee-related function and that the large majority of athletes who attempted to return to sport were successful. The majority of athletes (94%) were satisfied with their operative treatment.

Robson K, Pope R, Orr R. Incidence and Risk Factors for Acute Articular Cartilage Tears in Military and Other Occupational Settings: A Systematic Review. Healthcare (Basel) 2024; 12:595. [PMID: 38470706 PMCID: PMC10931416 DOI: 10.3390/healthcare12050595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 02/27/2024] [Accepted: 03/04/2024] [Indexed: 03/14/2024] Open
Abstract
Damage to the articular cartilage resulting in an acute tear can lead to functional changes within the joint and increase the risk of osteoarthritis developing. There is limited understanding of the association between occupational risk factors and sustaining an acute articular cartilage tear in the military and other physically demanding occupations. Therefore, the aim of this systematic review was to identify and evaluate original research reporting on occupational risk factors associated with sustaining acute articular cartilage tears. METHODS A systematic review following the Preferred Reporting Items for Systematic review and Meta-Analysis-Protocols was conducted and registered with the Open Science Framework. Key academic databases were searched using terms from the following concepts: risk or cause, paid occupations, and acute articular cartilage tears. RESULTS Of an initial 941 studies, 2 studies met the eligibility criteria, both reporting data from military contexts; only one evaluated acute articular cartilage tears in both males and females. One paper focused on articular cartilage injury within the knee and the other within the ankle joint with incidence rates being 0.2 and 0.3 per 1000 person-years, respectively. People in more physically active occupations and individuals with an above-normal body mass index were reported as being at higher risk of sustaining an acute articular cartilage tear. CONCLUSION Physically demanding occupations, such as the military, may increase the risk for acute tears of the articular cartilage. However, the findings of this review indicate there is a paucity of research to underpin understanding of the injury mechanisms and occupational risk factors for acute articular cartilage tears.

Abstract
PURPOSE The purpose of this study is to evaluate the quality of patient education materials accessible through popular online search engines regarding anterior cruciate ligament (ACL) injuries and anterior cruciate ligament reconstruction (ACLR). Methods: Two search terms ("ACL surgery" and "ACL reconstruction") were entered into three search engines (Google, Yahoo, and Bing). The quality of information was scored using a novel scoring system developed and overseen by sports medicine orthopedic clinical research fellows and fellowship-trained orthopedic surgeons. Website quality, credibility, and readability were further assessed by the DISCERN score, Journal of the American Medical Association (JAMA) benchmark criteria, and Flesch-Kincaid Reading Grade Level (FKRGL), respectively. The Health On the Net Code of Conduct (HONcode) certification was also utilized to assess the transparency of health information for each website. RESULTS We evaluated 39 websites. The average score for all websites was 11.2±5.6 out of 28 total points. Six out of the 39 websites (41%) were HONcode certified. The websites that contained HONcode certification had a higher average JAMA benchmark score (3.5±0.7) and DISCERN score (44.6±14.7) when compared to the websites without the certification, 2.2±1.2 and 37.6 ± 15.9 for JAMA and DISCERN, respectively. The mean JAMA benchmark score was 2.7±1.2 (67.5%) for all websites out of a possible four points. The average FKRGL for all 39 websites was 10.0±2.0 (range: 5.4-13). CONCLUSION The quality of patient education materials accessible on the internet regarding ACL injuries and ACLR can be misleading and directly impact the patient's decision-making process essential to the patient-physician relationship over the past decade. CLINICAL RELEVANCE The internet can be a helpful online resource, however, surgeon clarification and consultation with qualified healthcare professionals are strongly recommended prior to clinical decision-making regarding potential treatment options.

Abstract
Aims The aim of this study was to evaluate the association between chondral injury and interval from anterior cruciate ligament (ACL) tear to surgical reconstruction (ACLr). Methods Between January 2012 and January 2022, 1,840 consecutive ACLrs were performed and included in a single-centre retrospective cohort. Exclusion criteria were partial tears, multiligament knee injuries, prior ipsilateral knee surgery, concomitant unicompartmental knee arthroplasty or high tibial osteotomy, ACL agenesis, and unknown date of tear. A total of 1,317 patients were included in the final analysis, with a median age of 29 years (interquartile range (IQR) 23 to 38). The median preoperative Tegner Activity Score (TAS) was 6 (IQR 6 to 7). Patients were categorized into four groups according to the delay to ACLr: < three months (427; 32%), three to six months (388; 29%), > six to 12 months (248; 19%), and > 12 months (254; 19%). Chondral injury was assessed during arthroscopy using the International Cartilage Regeneration and Joint Preservation Society classification, and its association with delay to ACLr was analyzed using multivariable analysis. Results In the medial compartment, delaying ACLr for more than 12 months was associated with an increased rate (odds ratio (OR) 1.93 (95% confidence interval (CI) 1.27 to 2.95); p = 0.002) and severity (OR 1.23 (95% CI 1.08 to 1.40); p = 0.002) of chondral injuries, compared with < three months, with no association in patients aged > 50 years old. No association was found for shorter delays, but the overall dose-effect analysis was significant for the rate (p = 0.015) and severity (p = 0.026) of medial chondral injuries. Increased TAS was associated with a significantly reduced rate (OR 0.88 (95% CI 0.78 to 0.99); p = 0.036) and severity (OR 0.96 (95% CI 0.92 to 0.99); p = 0.017) of medial chondral injuries. In the lateral compartment, no association was found between delay and chondral injuries. Conclusion Delay was associated with an increased rate and severity of medial chondral injuries in a dose-effect fashion, in particular for delays > 12 months. Younger patients seem to be at higher risk of chondral injury when delaying surgery. The timing of ACLr should be optimally reduced in this population.

Abstract
Background and Objectives: The medial collateral ligament (MCL) is one of the major supporting ligaments of the knee joint, and MCL injuries are common where excessive valgus loading is applied to the knee joint. Although most MCL injuries can be treated conservatively, healing of the MCL can take several weeks to months. Furthermore, once injured, the biomechanical properties of the healed MCL differ from those of the native MCL, resulting in an increased risk of re-injury and chronic remnant symptoms. Mesenchymal stem cells (MSCs), owing to their therapeutic potential, have been investigated in various musculoskeletal injuries, and some preclinical studies regarding MSC-based approaches in MCL injuries have shown promising results. Despite satisfactory results in preclinical studies, there is still a lack of clinical studies in the orthopedic literature. This article describes the basic knowledge of the MCL, standard treatments for MCL injuries, and recent studies regarding the application of MSCs for enhanced healing of the MCL. MSC-based approaches are expected to be a potential therapeutic option for enhanced healing of the MCL in the future.

Abstract
Multiligamentous knee injuries (MLKI) are rare but devastating injuries that have a potential to cause long-term sequelae and significant morbidity. Frequently occurring concomitantly with knee dislocations (KD), MLKI have many risk factors that influence their incidence and treatment outcomes. Proper understanding of these risk factors can assist the surgeon with evaluation, surgical planning, and managing patient expectations both pre- and postoperatively. The purpose of this review is fourfold: (1) identify the risk factors and injuries associated with MLKI, (2) describe factors implicated in the treatment of MLKI, (3) report the effect of these risk factors on outcomes of MLKI, and (4) provide a brief insight into MLKI at our tertiary referral academic care center. This was a retrospective review of literature relevant to MLKI. Studies that described injuries, risk factors, treatment techniques, or outcomes associated with MLKI were included in our review. A total of 35 studies (consisting of level 3 and 4 evidence) published between 2009 and 2020 were found and included in our analysis. In addition, 25 patients who underwent treatment for MLKI at the University of Chicago Medical Center between December 2015 and December 2019 were included in our analysis. MLKI tend to occur in the younger male population. Increasing age, body mass index, and severity of the injury have been correlated with worse functional and patient-reported outcomes. Operative treatment is indicated for MLKI; however, timing and repair versus reconstruction is still debated, and is often decided on a patient by patient basis. Retrospective cohort studies have indicated that reconstruction may be favored; however, further more rigorous studies are needed to better characterize this finding. MLKIs are devastating injuries with significant variability in presentation, treatment, and outcome. Variations in these are largely attributable to the mechanism and severity of injury, timing, and surgeon preference. A holistic approach, and understanding of the present literature, is required to best optimize patient outcome.

Abstract
PURPOSE Meniscal injuries occurring during multi-ligament knee injuries (MLKI) are underreported. The purpose of this study was to compare the incidence and type of meniscal tears seen at the time of multi-ligament reconstruction surgery compared to those occurring during isolated anterior cruciate ligament (ACL) surgery. METHODS Patients undergoing surgical treatment for MLKI and ACL-only injuries between 2010 and 2020 were reviewed. Two-hundred and thirty-five patients were included in the MLKI group. There were 131 chronic injuries and 104 acute injuries. Two-hundred and twenty-two ACL-only chronic injuries were used as a control group for comparison with the chronic MLKI group. Demographic data, type of meniscal tears, ligament injury patterns (Schenck classification) and time from injury to surgery were recorded. A delayed procedure was defined by a 4-week interval after the knee injury. RESULTS A meniscus was torn in 69 knees (29.4%): 36 knees (15.3%) with an isolated medial meniscus tear, 33 knees (17.9%) with an isolated lateral meniscus tear,.Nine knees (3.8%) had both menisci torn. MLKI with medial or lateral-sided bicruciate ligament injuries (KDIIIM-KDIIIL) were significantly associated with a lower rate of meniscal tears than knee injuries involving the ACL-only and medial/lateral-sided ligament injuries (KDI) (medial-sided injuries p = 0.025; lateral-sided injuries p = 0.049). Lateral-sided injuries had significantly less meniscal damage than medial-sided injuries: 22/124 (17.7%) vs. 41/100 (41%); (p < 0.001). No significant differences were found for frequency, type and distribution of meniscal tears between acute and chronic MLKI surgery. ACL-only chronic injuries were associated with a higher rate of meniscal tears: 123/222 knees (55.4%) vs. 35/131 (26.9%) chronic MLKI; (p < 0.001), mainly involving the medial meniscus: 102/222 (46%) vs. 18/131 (13.7%); (p < 0.001). CONCLUSIONS Meniscal tears were less common in the MLKI group than in the isolated ACL injury group. The degree of ligament injury patterns and the side of the injured collateral ligament influenced the type and incidence of meniscal damage. Contrary to isolated ACL injuries, a delayed procedure was not associated with a higher rate of meniscal lesions but did influence the type of treatment. Understanding of meniscal tears patterns in MLKI helps to improve the treatment management of these complex injuries.

Abstract
INTRODUCTION Peroneal nerve injuries are rare injuries and usually associated with multiligamentous knee injuries (MLKIs) involving one or both cruciate ligaments. The purpose of our study was to perform a multicenter retrospective cohort analysis to examine the rates of peroneal nerve injuries and to see whether a peroneal nerve injury was suggestive of a particular injury pattern. METHODS A retrospective chart review was conducted in patients who were diagnosed with MLKI at two level I trauma centers from January 2001 to March 2021. MLKIs were defined as complete injuries to two or more knee ligaments that required surgical reconstruction or repair. Peroneal nerve injury was clinically diagnosed in these patients by the attending orthopaedic surgeon. Radiographs, advanced imaging, and surgical characteristics were obtained through a chart review. RESULTS Overall, 221 patients were included in this study. The mean age was 35.9 years, and 72.9% of the population was male. Overall, the incidence of clinical peroneal nerve injury was 19.5% (43 patients). One hundred percent of the patients with peroneal nerve injury had a posterolateral corner injury. Among patients with peroneal nerve injury, 95.3% had a complete anterior cruciate ligament (ACL) rupture as compared with 4.7% of the patients who presented with an intact ACL. There was 4.4 times of greater relative risk of peroneal nerve injury in the MLKI with ACL tear group compared with the MLKI without an ACL tear group. No statistical difference was observed in age, sex, or body mass index between patients experiencing peroneal nerve injuries and those who did not. CONCLUSION The rate of ACL involvement in patients presenting with a traumatic peroneal nerve palsy is exceptionally high, whereas the chance of having a spared ACL is exceptionally low. More than 90% of the patients presenting with a nerve palsy will have sustained, at the least, an ACL and posterolateral corner injury. LEVEL OF EVIDENCE IV, Case Series.

Abstract
Background The management of combined anterior cruciate ligament (ACL) and medial collateral ligament (MCL) injuries remains contentious. Clinical outcomes of surgical, conservative, and combined approaches have been described in a range of prospective and retrospective studies. The aim of the current systematic review was to evaluate these outcomes and assess the study methodologies. Methods A comprehensive literature search of the following databases was performed: PubMed, OVID, Cochrane Database of Systematic Reviews and Google Scholar. Studies were assessed using the Coleman Methodology Score. Results 52 articles were included (3 randomised controlled trials, 8 prospective comparative studies, 17 retrospective comparative studies and 24 case series). Outcome measures were heterogeneous amongst articles. The most common outcomes assessed were AP laxity, Lysholm score and medial/valgus laxity. Complications at varying follow-up times with differing grades of MCL injury were reported in 25 (48%) studies. Evidence was conflicting, with no consensus from the available published literature regarding the best method of treatment for a combined ACL and MCL injury. Conclusions Heterogeneous outcome measures and limited randomised controlled trials prevent advocacy of a single treatment option. Good outcomes have been reported from repair, reconstruction and conservative management of the MCL together with ACL reconstruction. Further prospective comparative data is required to evaluate MCL management choice and prognostic signs for successful nonsurgical MCL treatment.

Abstract
The purpose of this study was to describe the pattern of meniscus and cartilage pathology in multiligament knee injuries (MLKIs) and determine the relationship between surgical timing and injury mechanism with degree of intra-articular injury. Patients with surgically treated MLKIs over a 15-year period were retrospectively reviewed and grouped based on surgical intervention, time to intervention, and injury mechanism. The presence or absence of meniscus and chondral injury were recorded at the time of surgery. Surgical intervention within 6 weeks of injury was deemed acute, while surgery occurring more than 6 weeks from injury was classified as delayed. Over the 15-year study period, 207 patients with MLKIs were identified. Compared with acutely managed patients, the delayed intervention group had significantly more meniscus (p = 0.03) and cartilage (p < 0.01) pathology. Meniscus injury rates in MLKIs sustained during sporting activity did not differ from nonsporting injuries (p = 0.63). However, the nonsporting group had significantly more chondral injuries (p < 0.01). High-energy injury mechanism was associated with increased cartilage (p = 0.02), but not meniscus (p = 0.61) injury rates. In conclusion, surgical reconstruction of MLKIs delayed for more than 6 weeks was associated with increased meniscus and cartilage pathology.

Zsidai B, Horvath A, Winkler PW, Narup E, Kaarre J, Svantesson E, Musahl V, Hamrin Senorski E, Samuelsson K. Different injury patterns exist among patients undergoing operative treatment of isolated PCL, combined PCL/ACL, and isolated ACL injuries: a study from the Swedish National Knee Ligament Registry. Knee Surg Sports Traumatol Arthrosc 2022; 30:3451-3460. [PMID: 35357530 PMCID: PMC9464165 DOI: 10.1007/s00167-022-06948-x] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Accepted: 03/15/2022] [Indexed: 11/30/2022]
Abstract
PURPOSE To compare demographic characteristics and concomitant injury patterns in patients undergoing primary isolated posterior cruciate ligament reconstruction (PCL-R) and combined posterior cruciate ligament (PCL) and anterior cruciate ligament (ACL) reconstruction (PCL-R/ACL-R) with isolated ACL reconstruction (ACL-R) as a reference using data from the Swedish National Knee Ligament Registry (SNKLR). METHODS This cohort study based on the SNKLR comprised patients undergoing either PCL-R, ACL-R, or combined PCL-R/ACL-R between January 1, 2005 and December 31, 2019 in Sweden. Demographic and surgery-related data with regards to injury mechanism, concomitant intraarticular lesions and their treatment, neurovascular damage, and concomitant ligamentous injuries were extracted. Exclusion criteria included concomitant fractures of the femur, fibula, patella or tibia, and quadriceps or patellar tendon injury. RESULTS A total of 45,564 patients were included in this study. Isolated PCL-R, combined PCL-R/ACL-R, and isolated ACL-R were performed in 192 (0.4%), 203 (0.5%) and 45,169 (99.1%) patients, respectively. Sports were identified as the cause of 64% of PCL-Rs, 54% of PCL-R/ACL-Rs, and 89% of ACL-Rs, while a traffic-related mechanism was identified in 20% of PCL-Rs, 27% of PCL-R/ACL-Rs and 2% of ACL-Rs. Meniscus injury prevalence was 45% in ACL-Rs, 31% in PCL-R/ACL-Rs and 16% in isolated PCL-Rs (p < 0.001). Cartilage injuries were more common in PCL-R (37%) and PCL-R/ACL-R patients (40%) compared to ACL-R patients (26%, p < 0.001). Concomitant knee ligament injury was identified in 28-44% of PCL-R/ACL-R patients. Neurovascular injuries were present in 9% of PCL-R/ACL-Rs, 1% of PCL-Rs, and 0.3% of ACL-Rs (p < 0.001). CONCLUSION Differences in injury mechanisms among patient groups confirm that operatively treated PCL tears are frequently caused by both traffic and sports. Cartilage and ligament injuries were more frequent in patients with PCL-R compared to ACL-R. Consequently, combined PCL and ACL tears should raise suspicion for concomitant knee lesions with clinical relevance during the operative treatment of these complex injuries. LEVEL OF EVIDENCE III.

Medial collateral ligament reconstruction graft isometry is effected by femoral position more than tibial position. Knee Surg Sports Traumatol Arthrosc 2021; 29:3800-3808. [PMID: 33454831 PMCID: PMC8514388 DOI: 10.1007/s00167-020-06420-8] [Citation(s) in RCA: 27] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Accepted: 12/14/2020] [Indexed: 01/13/2023]
Abstract
PURPOSE The purpose of this study was to examine the length change patterns of the native medial structures of the knee and determine the effect on graft length change patterns for different tibial and femoral attachment points for previously described medial reconstructions. METHODS Eight cadaveric knee specimens were prepared by removing the skin and subcutaneous fat. The sartorius fascia was divided to allow clear identification of the medial ligamentous structures. Knees were then mounted in a custom-made rig and the quadriceps muscle and the iliotibial tract were loaded, using cables and hanging weights. Threads were mounted between tibial and femoral pins positioned in the anterior, middle, and posterior parts of the attachment sites of the native superficial medial collateral ligament (sMCL) and posterior oblique ligament (POL). Pins were also placed at the attachment sites relating to two commonly used medial reconstructions (Bosworth/Lind and LaPrade). Length changes between the tibiofemoral pin combinations were measured using a rotary encoder as the knee was flexed through an arc of 0-120°. RESULTS With knee flexion, the anterior fibres of the sMCL tightened (increased in length 7.4% ± 2.9%) whilst the posterior fibres slackened (decreased in length 8.3% ± 3.1%). All fibre regions of the POL displayed a uniform lengthening of approximately 25% between 0 and 120° knee flexion. The most isometric tibiofemoral combination was between pins placed representing the middle fibres of the sMCL (Length change = 5.4% ± 2.1% with knee flexion). The simulated sMCL reconstruction that produced the least length change was the Lind/Bosworth reconstruction with the tibial attachment at the insertion of the semitendinosus and the femoral attachment in the posterior part of the native sMCL attachment side (5.4 ± 2.2%). This appeared more isometric than using the attachment positions described for the LaPrade reconstruction (10.0 ± 4.8%). CONCLUSION The complex behaviour of the native MCL could not be imitated by a single point-to-point combination and surgeons should be aware that small changes in the femoral MCL graft attachment position will significantly effect graft length change patterns. Reconstructing the sMCL with a semitendinosus autograft, left attached distally to its tibial insertion, would appear to have a minimal effect on length change compared to detaching it and using the native tibial attachment site. A POL graft must always be tensioned near extension to avoid capturing the knee or graft failure.

Abstract
Posterior cruciate ligament (PCL) injuries commonly occur in association with participation in sporting or recreational activities or due to a direct trauma. Cartilage and meniscal lesions are prevalent in PCL-injured knees with increasing likelihood and severity based on extent and duration of trauma to the knee. As such, comprehensive diagnostics should be performed to ascertain all related pathology, and patients should be thoroughly educated regarding treatment options, likely sequelae including posttraumatic osteoarthritis, and associated outcomes. Treatments should address the joint as an organ, ensuring stability, alignment, and functional tissue restoration are optimized by the most efficient and effective means possible. Compliance with patient- and procedure-specific postoperative management protocols is critical for optimizing successful outcomes for these complex cases. The objectives of this review article are to highlight the likelihood and importance of osteochondral and meniscal pathology in the PCL-injured knee, and to provide the best current evidence regarding comprehensive evaluation and management for PCL-injured knees with cartilage and/or meniscal comorbidities.

Abstract
Purpose Describe the frequency and severity of knee ligament sprains diagnosed by MRI in athletes participating at the 2016 Summer Olympic Games, their association with certain sports and assess correlations with additional knee structural injury. Patients and Methods All knee MRIs performed in the Olympic Village and polyclinics during the 2016 Olympics were retrospectively, blindly reviewed for ligament sprains and associated knee injuries. In addition to the absence or presence of these abnormalities, athletes were stratified by age, gender and sport. Results 11,274 athletes participated in the 2016 Olympic Games: 113 athletes received at least one knee MRI with some having bilateral or repeat MRI on the same knee. Anterior cruciate and medial collateral ligament (ACL/MCL) sprains were most common, accounting for 32 of the 43 sprains (74.4%). Wrestling (10), hockey (7), athletics (7), and judo (5) accounted for over half of ligament sprains. ACL sprains showed a significant positive correlation with medial, lateral meniscal tears and bone contusions. The positive correlation between posterior cruciate ligament (PCL) sprains with MCL/lateral collateral ligament sprain, and popliteus tendon tear was statistically significant with 50% of total PCL sprains occurring in hockey. When athletes were stratified by gender, ligament sprains had a similar occurrence and distribution between men and women. Conclusion Knee ligament sprains, at the Rio 2016 Games, were most common in wrestling, hockey, athletics and judo with ACL and MCL sprains most frequent. Meniscal tears and bone contusions occurred often with ACL sprains. PCL sprains tended to be multi-ligamentous injuries. Sustained ligament sprains had similar occurrence between genders, while men had a peak incidence of sprains at a younger age and women at an older age.

Abstract
PURPOSE In knee dislocation with bicruciate ligament and medial side injury (KDIIIM), treatment method of medial side injuries is controversial. The purpose of this study was to evaluate the outcomes of non-operative treatment of proximal and midsubstance and operative treatment of distal avulsion medial collateral ligament (MCL) ruptures in patients with early bicruciate reconstruction. METHODS One-hundred and forty-seven patients with a knee dislocation and bicruciate ligament injury (KDII-KDV) were identified. Sixty-two patients had KDIIIM injury. Of these, 24 patients were excluded and 13 were lost to follow-up. With a minimum of 2 years of follow-up, IKDC2000 (subjective and objective), Lysholm and Tegner scores and stress radiographs were recorded. RESULTS Twenty-five patients were available for follow-up: 18 had a proximal or midsubstance grade-III MCL rupture (proximal MCL group) and 7 had a distal MCL avulsion (distal MCL group). In the proximal MCL and distal MCL groups, respectively, median IKDC2000 subjective scores were 80 (range 57-99) and 62 (range 39-87), and median Lysholm scores were 88 (range 57-99) and 75 (range 40-100). The median medial opening (side-to-side difference) was 2.4 mm (range 0.1-9.2) in the proximal MCL group and 2.5 mm (range 0.2-4.8) in the distal MCL group. CONCLUSION We found acceptable recorded outcomes in patients who underwent non-operative treatment of proximal and midsubstance grade-III MCL rupture and operative treatment of distal MCL avulsion with early bicruciate ligament reconstruction.

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
PURPOSE There are few descriptions of outcomes after posterior cruciate ligament (PCL) reconstruction in the literature due to the rarity of this type of knee injury. Since 2005, the Danish Knee Ligament Reconstruction Registry (DKRR) has monitored outcomes of PCL reconstructions. This study describes the epidemiology of PCL reconstruction and subsequent outcomes in a Danish population. METHODS Of 23,253 knee ligament reconstructions performed in 2005-2015, 581 were registered as PCL reconstructions in the DKRR. The types of reconstruction were classified as isolated (n = 237) or multi-ligament (n = 344), and the cause of injury and concomitant meniscus and cartilage injury data were extracted. The outcome at 1-year follow-up was based on the Knee Injury and Osteoarthritis Outcome Score (KOOS) and Tegner activity level. The outcome data were compared with data on 21.820 primary anterior cruciate ligament (ACL) reconstructions. RESULTS Isolated PCL reconstruction was performed in 43% of cases. Meniscus lesions and cartilage lesions were seen in 19 and 15% of cases, respectively. The main causes of PCL injuries were sports (43%) and traffic accidents (33%). The KOOS improved from pre-operative to 1-year follow-up for both isolated PCL reconstructions and multi-ligament PCL reconstructions but did not reach the levels of those recorded in ACL reconstructions. Multi-ligament reconstructions showed the highest improvement in KOOS. The Tegner activity levels for isolated and multi-ligament PCL reconstructions were 4 (0-7) and 4 (0-8), respectively. CONCLUSIONS PCL reconstructions represented only 2.6% of all knee ligament reconstructions in Denmark. Sports and traffic accidents were the main causes of injury. Meniscus and cartilage injuries were less frequent in PCL injuries as compared to ACL injuries. Isolated PCL and multi-ligament PCL reconstructions showed significant improvements in subjective outcomes but did not reach those observed in ACL reconstructions. Patients should be counselled about expected outcomes after PCL reconstruction. LEVEL OF EVIDENCE III.

Abstract
This statement aimed at summarising and appraising the available evidence for risk factors, diagnostic tools and non-surgical treatments for patients with meniscal tears. We systematically searched electronic databases using a pragmatic search strategy approach. Included studies were synthesised quantitatively or qualitatively, as appropriate. Strength of evidence was determined according to the Grading of Recommendations Assessment Development and Evaluation framework. Low-quality evidence suggested that overweight (degenerative tears, k=3), male sex (k=4), contact and pivoting sports (k=2), and frequent occupational kneeling/squatting (k=3) were risk factors for meniscal tears. There was low to moderate quality evidence for low to high positive and negative predictive values, depending on the underlying prevalence of meniscal tears for four common diagnostic tests (k=15, n=2474). Seven trials investigated exercise versus surgery (k=2) or the effect of surgery in addition to exercise (k=5) for degenerative meniscal tears. There was moderate level of evidence for exercise improving self-reported pain (Effect Size (ES)-0.51, 95% CI -1.16 to 0.13) and function (ES -0.06, 95% CI -0.23 to 0.11) to the same extent as surgery, and improving muscle strength to a greater extent than surgery (ES -0.45, 95% CI -0.62 to -0.29). High-quality evidence showed no clinically relevant effect of surgery in addition to exercise on pain (ES 0.18, 95% 0.05 to 0.32) and function (ES, 0.13 95% CI -0.03 to 0.28) for patients with degenerative meniscal tears. No randomised trials comparing non-surgical treatments with surgery in patients younger than 40 years of age or patients with traumatic meniscal tears were identified. Diagnosis of meniscal tears is challenging as all clinical diagnostic tests have high risk of misclassification. Exercise therapy should be recommended as the treatment of choice for middle-aged and older patients with degenerative meniscal lesions. Evidence on the best treatment for young patients and patients with traumatic meniscal tears is lacking.

Abstract
PURPOSE To determine if mechanism of injury is predictive of concomitant knee pathology found at the time of anterior cruciate ligament (ACL) reconstruction. METHODS All patients aged 16 to 35 who underwent ACL reconstruction at our institution between January 2009 and December 2015 were retrospectively reviewed. Mechanism of injury was determined from patient history. The presence of meniscal or chondral damage was determined from operative records, while collateral ligament injuries were determined by the treating surgeon's diagnosis after physical examination and their review of magnetic resonance imaging findings. Patients with inadequate documentation, history of a subsequent instability episode following the initial injury, or prior history of knee pathology were excluded. RESULTS Six hundred eighty-seven patients (169 contact and 518 noncontact) were included. A 2-fold increase in the incidence of collateral ligament injury was identified between the 2 groups with 114 (67.5%) in the contact group and 175 (33.8%) in the noncontact group (P < .001). Twenty-six patients (15.4%) in the contact group compared with 9 (1.7%) in the noncontact group had a grade III collateral ligament injury (P < .001). Chondral injury was identified in 41 (24.3%) patients in the contact group and 87 (16.8%) in the noncontact group (P = .05) with 9 (5.3%) grade IV lesions in the contact group and 4 (0.8%) in the noncontact group (P < .001). Eleven patients in the contact group (6.5%) and 15 in the noncontact group (2.9%) had a chondral injury to the lateral femoral condyle (P = .04). CONCLUSIONS Although we found no difference in the incidence or type of meniscal tears, we found a significant increase in the incidence of grade IV chondral injury, chondral injury to the lateral femoral condyle, and grade III collateral ligament damage in the setting of contact ACL injuries.

Abstract
Background Meniscal lesions are among the most common injuries of the knee, yet limited epidemiologic data is available on their risk factors. We investigated the association of lifestyle factors and physical strenuousness of work on knee injuries with a focus on meniscal lesions. Methods We examined a nationally representative sample of persons aged 30 to 59 years, who participated in a comprehensive health examination (the Mini-Finland Health Survey). Subjects without any injury or osteoarthritis in the knee joint at baseline (n = 4713) were subsequently followed via the National Hospital Discharge Register up to 30 years. Results During the follow-up, 338 knee injuries were identified of which 224 were meniscal lesions. Obesity and regular leisure time physical exercise were associated with an increased risk of first hospitalization due to meniscal lesions (hazard ratio (HR) 1.62 and 95% confidence interval (CI) 1.06–2.48 and 1.53, 95% CI 1.05–2.23, respectively). The types of sports predicting the highest risk of meniscal lesions were ballgames, gymnastics and jogging. Physical strenuousness of work did not predict meniscal lesion. The hazard of other knee injury was increased among those reporting irregular or regular physical exercise at baseline (HR 1.64, 95% CI 1.03–2.64 and 1.88 CI 1.05–2.36, respectively). Smoking or alcohol intake were not associated with knee injuries. Conclusions Better safety measures in high-risk sports and weight control would likely improve the prevention of meniscal lesions in populations.

Abstract
OBJECTIVES The objectives of this study were to determine (1) if patients undergoing reconstruction of an isolated anterior cruciate ligament (ACL) tear had different characteristics (age, gender, body mass index [BMI]) than patients undergoing ACL reconstruction (ACLR) with multiple knee ligament (MKL) tears and (2) whether there was a difference in prevalence of articular cartilage injury and meniscus tears between these two groups. METHODS Patients undergoing primary ACLR between February 2005 and June 2013 were identified through an ACLR registry. Patients were grouped by whether they had an isolated ACL tear or an ACL tear associated with another knee ligament tear. The study cohort was analyzed to identify differences in patient characteristics and cartilage/meniscus injury patterns between the groups. RESULTS Of the 21,377 ACLR cases enrolled in the registry during the study period, 2.5% (n = 549) had MKL tears. The MKL group had more males (73.2% vs. 62.8%, p < 0.001) than the isolated ACL group. The MKL group also had a higher percentage of patients with a BMI greater than 30 (31.1% vs. 22.7%, p = 0.0002). When adjusting for these variables, any articular cartilage injury was equal in the two groups (OR = 1.01, CI 0.82-1.25, p = 0.922), while medial femoral condyle injury was less common in the MKL group (OR = 0.73, CI = 0.56-0.07, p = 0.28). The likelihood of any meniscus tear was lower in the MKL group (OR = 0.56, CI = 0.47-0.67, p < 0.001) as was the likelihood of medial meniscus tears (OR = 0.53, CI = 0.44-0.65, p < 0.001). CONCLUSIONS When comparing patients with MKL tears versus isolated ACL tears at ACLR, there was a higher percentage of males and patients with BMI over 30 in the MKL group. Medial femoral condyle articular cartilage injury, any meniscus tear, and medial meniscus tears were less common in patients with MKL injury compared to patients with isolated ACL tears.

Abstract
Background: Anterior cruciate ligament (ACL) tear is the most frequent injury in alpine ski racing, and there is a high prevalence of ACL reinjury. Limited data exist on the concurrent pathology with primary ACL tears in elite alpine ski racers and the magnitude of injury progression after primary ACL reconstruction (ACLR). Purpose: To evaluate (1) the involvement of intra-articular and multiligament pathologies at the time of primary ACLR, (2) the subsequent progression in meniscal/chondral injuries, and (3) the occurrence of ACL reinjury in elite alpine ski racers. Study Design: Case series; Level of evidence, 4. Methods: Primary ACLR operative reports (n = 28) were obtained for 32 elite alpine ski racers along with the reports of 20 operative procedures that occurred subsequent to primary ACLR. Operative reports were evaluated to identify the presence/location of multiligament injury, meniscal tears, and chondral lesions. Results: At the time of primary ACLR, a majority of knees (82%; 23/28) demonstrated concurrent injury compared with isolated ACL tears; 32% of knees sustained multiligament injuries (9/28), and 8 involved the ipsilateral medial collateral ligament (MCL). Of the ACL-injured knees, 54% had chondral lesions, of which 73% were sustained in the lateral knee compartment, and 82% of meniscal tears (14/17) were complex in nature. Bilateral ACL tears were seen in 22% of the participants, and 28% underwent ACL revision. In the case of ACL revision or future meniscal/chondral surgery, 60% of meniscal tears and 80% of chondral lesions had worsened since the time of primary ACLR. Conclusion: Concurrent injury was common in this group of elite ski racers. Primary ACL tears were typically accompanied by lateral compartment chondral lesions and complex meniscal tears that worsened over time. ACL/MCL tears were the most common multiligament injury pattern.

Abstract
Background Anterior cruciate ligament (ACL) injury is often accompanied with medial collateral ligament (MCL) injury. Assessment of varus-valgus (V-V) instability in the ACL-deficient knee is crucial for the management of the concomitant ACL-collateral ligaments injury. We evaluated the V-V laxity and investigated the effect of additional posterior tibial load on the laxity in the ACL-deficient knee. Our hypothesis was that the V-V laxity in the ACL-deficient knee was greater than that in the intact knee and attenuated by additional posterior tibial load. Methods Eight fresh-frozen porcine knees were used, and a 6°-of-freedom (DOF) robotic system was utilized. A 5 Nm of V-V torque was applied to the intact knee, the ACL-deficient knee, and the ACL-deficient knee with 30 N of constant posterior tibial load, at 30° and 60° of flexion. Then, the 3D path in the intact knee was reproduced on the ACL-deficient knee. The total V-V angle under 5 Nm of V-V torque was assessed and compared among the three statuses. The in situ forces of the ACL under 5 Nm of varus and valgus torques, respectively, were also calculated. Results The total V-V angle in the ACL-deficient knee under 5 Nm of V-V torque was significantly greater than that in the intact knee, whereas the angle in the ACL-deficient knee with 30 N of posterior tibial load was significantly smaller than that in the ACL-deficient knee and approached that in the intact knee, at both 30° and 60° of flexion. The in situ force of the ACL was approximately 30 N at 30° and 16 N at 60° of flexion under 5 Nm of both varus and valgus torques. Conclusions The V-V laxity in the isolated ACL-deficient knee was greater than that in the intact knee. The increased laxity was attenuated and approached that in the intact knee by adding posterior tibial load. Application of posterior tibial load is necessary for accurate assessment of V-V instability in the ACL-deficient knee. Clinically, the V-V laxity in the combined ACL-MCL or ACL-LCL injured knee may be overestimated without posterior tibial load.

Abstract
BACKGROUND The risk of major complications and revision arthroplasty after TKA in patients who previously underwent multiligament knee surgery have been poorly characterized. QUESTIONS/PURPOSES Is multiligament knee surgery before TKA associated with (1) worse implant survival, (2) increased use of TKA design constraint, (3) a greater risk for major complications, and (4) poorer scores for pain and function compared with similar patients receiving TKA for primary osteoarthritis? METHODS Fifty-nine TKAs were performed at our institution between 1985 and 2014 in 59 patients (36 men, 23 women; mean age, 53 years) with a history of previous multiligament knee surgery (≥ two ligaments). Of those, we had followup for 39 (66%), 18 (31%), and six (10%) patients at 5, 10, and 15 years, respectively; mean followup was 5.4 years (range, 1-25 years). A two-to-one matched control group consisting of patients undergoing primary TKA for the diagnosis of osteoarthritis was selected for comparison. Patients were matched based on gender, age at primary TKA (within 5 years), and date of the TKA (within 5 years). Medical records were reviewed for survivorship, TKA design, complications (reoperation, revision, infection, manipulation under anesthesia, and periprosthetic joint infection), TKA design, and clinical outcomes (Knee Society Scores [KSS], Knee Society Function Score [KSS-F]). RESULTS The overall 15-year revision-free survival in patients with prior multiligament knee surgery was decreased in comparison to the matched controls (42% [95% CI, 16%-73%] vs 94% [95% CI, 81%-99%]; p < 0.001). Varus-valgus constraint implant design was used for more patients in the multiligament cohort at index TKA than in the matched control group (9/59 [15%] vs 0/110 [0%], respectively; odds ratio [OR], 45; 95% CI, 3-781; p = 0.009). Patients with a history of multiligament knee surgery also were at increased risk of reoperation for any cause (14/59 [24%] vs 7/118 [6%]; OR, 5; 95% CI, 2-14; p = 0.001). With the numbers available, there was no difference in the frequency of manipulation under anesthesia after TKA (10% [6/59] versus 3% [4/118]; p = 0.08) A higher proportion of patients in the multiligament cohort had infections develop compared with the matched controls (4/59 [7%] vs 1/118 [< 1%)], respectively; p = 0.04). There was no difference in the KSS improvement after TKA between the multiligament group and the control group (34 ± 18 vs 28 ± 15; p = 0.088). The final KSS and KSS-F scores likewise showed no difference between those groups (88 ± 13 vs 85 ± 10; p = 0.232) (85 ± 17 vs 84 ± 14; p = 0.75). CONCLUSIONS A history of multiligament surgery is associated with lower long-term survivorship, higher use of constrained TKA designs, and higher risk of major complications, including reoperation and infection. Further research is necessary to determine if a particular multiligamentous surgical technique can prevent posttraumatic arthritis and TKA complications.

Abstract
PURPOSE Knee dislocations can cause significant damage to intra-articular knee structures, but currently there are limited data reporting articular cartilage and meniscal injuries in this setting. The purpose of this study is to (1) report the rate of concomitant intra-articular injuries at the time of multiligament reconstruction for knee dislocation, (2) determine whether the pattern of ligament injury is associated with the presence of chondral and meniscal injuries, and (3) assess the relationship between timing of surgery and incidence of chondral and meniscal injuries. METHODS The records of patients who sustained a knee dislocation between 1992 and 2013 were retrospectively reviewed. Patients included for further review had a PCL-based multiligament knee injury or a minimum of three disrupted ligaments, both indicative of knee dislocation. Patient demographics, ligament injury patterns, meniscal tears and chondral injuries at arthroscopy, and interval from injury to surgery were recorded. Early surgical intervention was defined as <3 months, delayed was between 3 and 12 months, and chronic was >12 months. Data analysis compared ligament injury pattern with chondral and meniscal injuries, as well as the rates of intra-articular injury by timing of surgery. RESULTS One-hundred and twenty-one patients (122 knees) were included (93 males, 28 females) with a median age at time of surgery of 31 years (range 15-62). Ninety-three knees (76 %) had associated chondral or meniscal injury. Sixty-seven knees (55 %) presented with meniscal tears (26 isolated medial, 27 isolated lateral, and 14 combined medial/lateral), while 52 knees (48 %) had chondral damage, most commonly in the medial compartment. Schenck classification as well as side of injury did not demonstrate consistent relationships with intra-articular injury. A higher incidence of damage to the lateral femoral condyle (20 % vs 3 %; p = 0.02), lateral tibial plateau (20 % vs 2 %; p < 0.01), and patella (40 % vs 13 %; p = 0.01) was found in the chronic group compared to the early group. The chronic group contained significantly more patients with bicompartmental and tricompartmental chondral lesions (25 % vs 6 %; p = 0.03 and 10 % vs 0 %; p = 0.02, respectively). CONCLUSION Meniscal tears and chondral damage occur frequently in patients with a knee dislocation. A longer interval from injury to surgical reconstruction is associated with higher rates of articular cartilage lesions, especially in multiple compartments. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE A paucity of data exists on the effects of articular cartilage and meniscal injury in the setting of knee dislocations. The purpose of this study is to determine whether concomitant intra-articular injuries at the time of multiligament reconstruction for knee dislocation are associated with inferior outcomes. METHODS The records of patients who underwent surgical treatment for multiligament knee injury between 1992 and 2012 were retrospectively reviewed. Patients included had a PCL-based multiligament knee injury or a minimum of three disrupted ligaments, both indicative of knee dislocation. A logistic regression model was used to determine whether articular cartilage injuries (grade 2 involving ≥50 % of the condylar width or greater, or any grade III/IV lesions) and meniscus tears are predictors of IKDC outcome scores collected at a minimum of 2 years postoperatively. RESULTS Of the 121 patients who met inclusion criteria, 2-year minimum follow-up was available on 95 patients (79 %). The cohort was 77 % male and had a median age of 32 years (16-62) at the time of surgery and was followed for an average of 6 years. Articular cartilage injury was present in 40 % of knees: medial femoral condyle (20 %); medial tibial plateau (9 %); lateral femoral condyle (5 %); lateral tibial plateau (4 %); patella (18 %); trochlear (5 %). Meniscal injury was present in 56 % of patients (isolated medial, 22 %; isolated lateral, 22 %; combined, 12 %). IKDC scores were significantly lower for patients with any cartilage damage (p = 0.03), combined medial and lateral meniscus tears (p = 0.02), medial-sided articular cartilage damage (p = 0.03), medial femoral condyle (p = 0.04) and trochlear (p = 0.03) lesions. CONCLUSION Articular cartilage damage and meniscus tears are frequently associated with a knee dislocation. This study showed IKDC scores were significantly lower for patients with cartilage damage or combined medial and lateral meniscus tears at mid-term follow-up of 6 years. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE To compare the knee ligamentous injury patterns and associated multisystem trauma in patients who have sustained simultaneous bilateral knee multiligamentous injuries (MLI) to patients with unilateral MLIs. METHODS Patients with simultaneous bilateral and unilateral knee MLIs after motor vehicle accidents were identified from 2007 to 2014 at a single institution. Chart and radiographic reviews were performed to identify patient demographics, extremity fractures and associated head, thoracic, abdominal and spine injuries. The MLIs were characterized by ligamentous injury pattern and associated neurovascular deficits. Injury Severity Score (ISS) and New ISS (NISS) were calculated. RESULTS Seven bilateral MLIs and 32 unilateral MLIs were identified. Between the cohorts, there were no significant differences in ligamentous injury pattern or associated neurovascular injuries. For the bilateral MLI cohorts, 71.4 % of patients sustained chest trauma, 57.1 % abdominal trauma, 57.1 % at least a single-level spine injury and 28.6 % head trauma. The ISS was 33.4 ± 23.4 with patients spending an average of 12.4 days in the intensive care unit. Other than the number of days in the ICU, these values were all significantly higher than those of the unilateral knee MLI cohort. Additionally, there was a significantly higher post-operative complication rate in the bilateral MLI cohort (71.4 vs. 6.3 %, P < 0.0001). CONCLUSION Compared to unilateral MLIs with similar mechanisms, patients with traumatic simultaneous bilateral knee multiligamentous knee injuries are at high risk of concomitant head, chest and abdominal injuries. Although the ligament injury profile is similar, the post-operative complication rate is higher for simultaneous bilateral injuries. LEVEL OF EVIDENCE Case control study, Level III.

Abstract
The purpose of this study was to investigate the latest trends and demographics of surgical treatment of posterior cruciate ligament (PCL) insufficiency in the United States. Patients who underwent surgical treatment of PCL insufficiency from 2007 to 2011 were identified by searching the International Classification of Diseases, Ninth Revision, Clinical Modification codes and Current Procedural Terminology codes in the PearlDiver Patient Records Database (PearlDiver Technologies, Warsaw, Indiana), a publicly available national database of insurance records. The chronicity of injury, year of procedure, age, sex, region of the United States the surgery was performed, and other concomitant meniscus and ligamentous operations were elicited for each patient. In total, 701 cases of surgical PCL procedures (222 isolated and 479 combined) were identified. More PCL surgeries were completed for acute injuries (74%) than for chronic injuries (26%). Among associated procedures, meniscectomies and meniscus repairs were performed for 293 (41%) and 51 (7%) patients, respectively. Meniscectomies were completed in 77 (35%) isolated reconstructions vs 216 (45%) combined reconstructions (P=.01; odds ratio, 0.65). Of the combined PCL surgeries, anterior cruciate ligament (ACL)/PCL was the most common (62%), followed by ACL/PCL/collateral ligament repair (11%) and PCL/other ligamentous reconstruction (9%). No specific trends were observed in the yearly number of PCL procedures performed. The peak number of isolated PCL surgeries was observed in a younger age group (20-29 years) than that of combined PCL surgeries (30-39 years) (P<.01). Surgical treatment for PCL insufficiency remains reserved for acute multiligamentous knee injuries, with ACL/PCL operations being the most common combined procedure.

Knee Surg Sports Traumatol Arthrosc 2015; 23:792-8. [PMID: 24141891 DOI: 10.1007/s00167-013-2718-2] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2013] [Accepted: 10/08/2013] [Indexed: 11/28/2022]
Abstract
PURPOSE To evaluate patient-specific factors, including the mechanism of injury, time from the injury, activity level after the initial trauma, re-injury and body mass index (BMI), as risk factors for meniscal and chondral injuries accompanying anterior cruciate ligament (ACL) rupture. METHODS A retrospective review of young adult patients with complete ACL rupture was performed between 2007 and 2011. The presence of meniscal tears and/or chondral injury, and the mechanism of injury, time from the injury, activity level after the initial trauma, re-injury and BMI were recorded. The data were analysed for associations between patient-specific factors and the prevalence of meniscal and chondral injuries. RESULTS A total of 293 patients were included. Increasing time from the injury, active daily life and re-injury were risk factors associated with meniscal injuries (p < 0.05). Independent risk factors associated with meniscal injuries included active daily life (OR = 4.66, 95 % CI 2.21-9.86, p < 0.0001) and re-injury (OR = 7.68, 95 % CI 3.24-18.22, p < 0.0001). Contact injury, increasing time from the injury, active daily life and re-injury were risk factors associated with chondral injuries (p < 0.05). Independent risk factors associated with chondral injuries included contact injury (OR = 2.54, 95 % CI 1.27-5.10, p < 0.01), active daily life (OR = 2.62, 95 % CI 1.35-5.08, p < 0.01) and re-injury (OR = 4.18, 95 % CI 2.09-8.35, p < 0.001). The incidence of re-injury was associated with the activity level (p < 0.001) and increased with increasing time from the injury (r = -0.698, p < 0.001). CONCLUSIONS An increased risk of meniscal tear (especially medial meniscus) was strongly associated with an active daily life and re-injury. The combination of contact injury, active daily life and re-injury substantially increased the risk of cartilage injury. Patients with increasing time from the injury and active daily life exhibited a higher risk of re-injury, implying a higher prevalence of intra-articular damage.

Postural stability in patients with anterior cruciate ligament tears with and without medial meniscus tears. Knee Surg Sports Traumatol Arthrosc 2015; 23:240-5. [PMID: 24037262 DOI: 10.1007/s00167-013-2675-9] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2013] [Accepted: 09/05/2013] [Indexed: 02/07/2023]
Abstract
PURPOSE To compare postural stability in patients with isolated anterior cruciate ligament (ACL) tears and ACL tears with associated meniscal tears. METHODS Quadriceps and hamstring muscle strength and their ratio, as well as the relationships of these parameters with postural stability, were compared in 23 patients with isolated ACL tears and 27 with combined ACL and medial meniscus tears. Postural stability was determined from the anterior-posterior, medial-lateral, and overall stability indices using the Biodex Stability System. RESULTS On both the involved and uninvolved sides, there were no differences in mean stability indices, including anterior-posterior, medial-lateral, and overall stability indices, in patients with isolated and combined ACL tears. In patients with isolated ACL tears, both overall (2.3 ± 1.2 vs. 1.8 ± 1.4, p = 0.033) and medial-lateral (1.2 ± 0.6 vs. 1.0 ± 0.5, p = 0.031) stability indices were significantly higher on the involved compared to the uninvolved side. These differences, however, were not observed in the combined ACL tear group. CONCLUSION No significant differences in postural instability on the affected and unaffected sides were observed in patients with isolated ACL tears and those with combined ACL and medial meniscus tears. These findings indicate that there is no need to reduce the goal of restoring proprioception in patients with combined compared with isolated ACL tears. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND Strong biomechanical and epidemiological evidence associates knee valgus collapse with isolated, noncontact anterior cruciate ligament (ACL) injuries. However, a concomitant injury to the medial collateral ligament (MCL) would be expected under valgus collapse, based on the MCL's anatomic orientation and biomechanical role in knee stability. Purpose/ HYPOTHESIS The purpose of this study was to investigate the relative ACL to MCL strain patterns during physiological simulations of a wide range of high-risk dynamic landing scenarios. We hypothesized that both knee abduction and internal tibial rotation moments would generate a disproportionate increase in the ACL strain relative to the MCL strain. However, the physiological range of knee abduction and internal tibial rotation moments that produce ACL injuries are not of sufficient magnitude to compromise the MCL's integrity consistently. STUDY DESIGN Controlled laboratory study. METHODS A novel in sim approach was used to test our hypothesis. Seventeen cadaveric lower extremities (mean age, 45 ± 7 years; 9 female and 8 male) were tested to simulate a broad range of landings after a jump under anterior tibial shear force, knee abduction, and internal tibial rotation at 25° of knee flexion. The ACL and MCL strains were quantified using differential variable reluctance transducers. An extensively validated, detailed finite element model of the lower extremity was used to help better interpret experimental findings. RESULTS Anterior cruciate ligament failure occurred in 15 of 17 specimens (88%). Increased anterior tibial shear force and knee abduction and internal tibial rotation moments resulted in significantly higher ACL:MCL strain ratios (P < .05). Under all modes of single-planar and multiplanar loading, the ACL:MCL strain ratio remained greater than 1.7, while the relative ACL strain was significantly higher than the relative MCL strain (P < .01). Relative change in the ACL strain was demonstrated to be significantly greater under combined multiplanar loading compared with anterior tibial shear force (P = .016), knee abduction (P = .018), and internal tibial rotation (P < .0005) moments alone. CONCLUSION While both the ACL and the MCL resist knee valgus during landing, physiological magnitudes of the applied loads leading to high ACL strain levels and injuries were not sufficient to compromise the MCL's integrity. CLINICAL RELEVANCE A better understanding of injury mechanisms may provide insight that improves current risk screening and injury prevention strategies. Current findings support multiplanar knee valgus collapse as a primary factor contributing to a noncontact ACL injury.

Abstract
STUDY DESIGN Systematic review with meta-analysis. OBJECTIVES To review and critically appraise the literature for factors that increase the risk for meniscal tears. BACKGROUND Meniscal tears are an important cause of disability and time lost from work, and are associated with a 4-fold increase in the long-term risk of knee osteoarthritis. Knowledge of the risk factors that lead to meniscal tears can help to correctly diagnose knee injuries and is important to the development of prevention strategies for knee osteoarthritis. METHODS A search of the Cochrane Database of Systematic Reviews, MEDLINE, and Embase, from 1950 to January 2012, and a hand search of reference lists of all initially selected studies, without restriction on language or date of publication, were conducted. Prospective, retrospective, and case-control studies that included individuals over 16 years of age, who had no previous meniscal injuries or surgeries, were selected. A meta-analysis for 17 risk factors was performed. Where considerable heterogeneity among studies was present or the data did not provide sufficient information to perform a meta-analysis, a qualitative synthesis was conducted. RESULTS Eleven studies, with a total of 7358 participants, were selected for systematic review. Data were available for meta-analysis for 10 of the 11 studies. Qualitative analysis was conducted using data from 3 of the 11 studies. Results showed strong evidence that age (older than 60 years), gender (male), work-related kneeling and squatting, and climbing stairs (greater than 30 flights) were risk factors for degenerative meniscal tears. We also found strong evidence that playing soccer and playing rugby were strong risk factors for acute meniscal tears. Waiting longer than 12 months between the anterior cruciate ligament injury and reconstructive surgery was a strong risk factor for a medial meniscal tear but not for a lateral meniscal tear. CONCLUSION The literature indicates a number of risk factors leading to either degenerative or acute meniscal tears, with some of these factors being potentially modifiable. LEVEL OF EVIDENCE Prognosis, level 2a.

Abstract
PURPOSE The goal of our study was to investigate the associations between surgical delay, pain and meniscus, and articular cartilage lesions seen at the time of ACL reconstruction. METHODS One hundred and sixty-two consecutive patients who had received ACL reconstruction were recruited. The preoperative International Knee Documentation Committee (IKDC) questionnaires, and cartilage and meniscal lesions seen at the time of surgery were analysed. RESULTS Patients with surgery within 12 months were less likely to have meniscus injury (59.8/77.4 %, p = 0.032), and the meniscus injury was more likely to be salvageable. (56.3/36.0 %, p = 0.042). Patients with meniscal tear larger than 10 mm had higher pain intensity than tear <10 mm (mean 6.8/8.2, p = 0.007). Patients older than 35 years of age were more likely to suffer from cartilage injury (76.4/39.1 %, p = 0.004). Patients with cartilage lesions had longer surgical delay (mean 18.9/12.1 months, p = 0.033). The presence of meniscal tear increased the risk of cartilage lesions (p = 0.038, OR = 2.14). Patients with cartilage lesions had a greater pain frequency (mean 6.9/7.7, p = 0.048). Moderate correlation was found between the size of cartilage lesion and the frequency of pain (p = 0.013). CONCLUSIONS Increased surgical delay was associated with an increased incidence of meniscus and articular cartilage injuries in patients suffering from ACL tear; also, the meniscus was less likely to be salvageable. The presence of cartilage lesions was associated with an increased frequency of pain. Size of meniscal and cartilage lesions was significantly associated with pain.

Abstract
Posterolateral (PLC) and posteromedial (PMC) corners of the knee represent complex anatomic regions because of intricate soft tissue and osseous relationships in small areas. Concise knowledge of these relationships is necessary before approaching their evaluation at imaging. Magnetic resonance imaging offers an accurate imaging diagnostic tool to establish normal anatomy and diagnose and characterize soft tissue and osseous injury. It is important to carefully evaluate the PLC and PMC structures on magnetic resonance imaging before planned surgical intervention to avoid potential complications resulting from occult injury.

Abstract
OBJECTIVES To determine the histological patterns of posterior cruciate ligament (PCL) degeneration during aging and in relation to changes in articular cartilage and anterior cruciate ligament (ACL) across the entire adult age spectrum. METHODS Human knee joints (n=120 from 65 donors) were processed within 72 h of postmortem. Articular cartilage surfaces were graded macroscopically. Each PCL was histologically evaluated for inflammation, mucinous changes, chondroid metaplasia, cystic changes and orientation of collagen fibres. The severity of PCL degeneration was classified as normal, mild, moderate or severe. PCL scores were compared to ACL and cartilage scores from the same knees. RESULTS All knees had intact PCL. Histologically, 6% were normal, 76% showed mild, 12% moderate and 9% severe degeneration. Fibre disorientation was the most prevalent and severe change. Histological grades of PCL and ACL correlated, but significantly fewer PCL than ACL showed severe changes. There was a weaker correlation between aging and total histological PCL scores (R=0.26) compared to aging and ACL scores (R=0.42). ACL scores correlated with cartilage scores (R=0.54) while PCL scores increased with the severity of osteoarthritis from grades 0 to III but not between osteoarthritis grades III-IV (R=0.32). In knees with ruptured ACL, the PCL scores correlated with cartilage scores of the lateral compartment. CONCLUSIONS PCL histopathological changes were less severe than in the ACL. PCL degeneration was associated with ACL and cartilage damage. The lack of correlation with age indicates independent pathways for PCL versus ACL degeneration.

Abstract
Injury to the posteromedial corner (PMC) of the knee differs anatomically and biomechanically from isolated injury to the medial collateral ligament. Newer anatomic and biomechanical studies are refining the field's understanding of the medial side of the knee, as well as its role in multiple ligament injuries. Valgus instability places additional strain on a reconstructed anterior or posterior cruciate ligament, which can contribute to late graft failure. Injuries to the PMC may not heal without surgical repair or reconstruction, particularly when part of a multiple-ligament injury. Identification of PMC injury before cruciate reconstruction is important so that appropriate repair or reconstruction of the PMC and medial collateral ligament can be undertaken at the same time. This article reviews the relevant literature on the PMC, discusses reasons for selective operative management, and illustrates reconstructive strategies for PMC injuries occurring as part of a medial-sided or multiligament injury to the knee.

Abstract
The medial collateral ligament (MCL) is the most commonly injured knee ligament. Such injuries in children are rare due to the relative thickness of the articular cartilage and physes that can absorb energy. Traumatic MCL entrapment into the medial knee joint in a child has not yet been reported. This article presents a case of intra-articular MCL entrapment in a 9-year-old boy with characteristic findings on magnetic resonance imaging (MRI) showing the interposition of the MCL between the medial meniscus and medial tibial plateau. During arthroscopic surgery, the MCL tear pattern was visualized underneath the medial meniscus. A medial knee incision was performed and the MCL was retrieved from the knee joint. The meniscotibial ligaments and medial meniscus were repaired to the tibial plateau. The torn ends of MCL were reapproximated and sutured. One year postoperatively, the patient is back to full activities including sports without limitations. This article should help raise awareness about the possibility of such injuries to avoid a delay in diagnosis. Although it is true that children would injure their physes more often than their ligaments due to their relative weakness, this article describes the possibility of a serious ligament injury without physeal involvement.

Abstract
OBJECTIVE Early detection of glycosaminoglycan (GAG) loss may provide insight into mechanisms of cartilage damage in the anterior cruciate ligament (ACL)-injured patient. We hypothesized that tibial and femoral Delayed Gadolinium-Enhanced MR Imaging of Cartilage (dGEMRIC) indices would be lower in the medial compartment of the ACL-injured knee than in the contralateral, uninjured knee, and that scan order (i.e., whether the injured or the uninjured knee was imaged first) would not affect the indices. METHODS 15 subjects with unilateral ACL injuries received a double dose of gadolinium [Gd(DTPA)(2-)] intravenously. After 90 min, both knees were sequentially imaged. The injured knee was scanned first in the odd-numbered subjects and second in the even-numbered subjects. The dGEMRIC indices of the median slice of the medial compartment were determined using the MRIMapper software. Index comparisons were made between knee status (ACL-injured vs uninjured), scan order (ACL-injured first vs uninjured first), and cartilage location (tibia vs femur) using a mixed model. RESULTS There was a significant difference in the mean dGEMRIC indices of the medial compartment between injured and uninjured knees (P<0.007). On average, there was a 13% decrease in the dGEMRIC index of the injured knee compared to the uninjured knee. There were no significant effects due to test order (P=0.800) or cartilage location (P=0.439). CONCLUSIONS The results demonstrate lower GAG concentrations in the medial compartment of the femoral and tibial articular cartilage of the ACL-injured knee when compared to the contralateral uninjured knee. The dGEMRIC indices were not sensitive to scan order; thus, sequential imaging of both knees is possible in this patient population.

Abstract
BACKGROUND Detailed descriptions of meniscus and articular cartilage lesions associated with anterior cruciate ligament injury have not been presented in the literature. Our goal was to determine the associations between patient sex, age, and surgical delay and the frequency and location of meniscus and articular cartilage lesions seen at the time of the anterior cruciate ligament reconstruction. METHODS Data were obtained retrospectively from a database of 1209 consecutive patients undergoing anterior cruciate ligament reconstruction between 1988 and 2002. All knee cartilage, meniscus, and ligament injuries were documented on anatomic maps at the time of surgery, and the data were analyzed. RESULTS Meniscus injuries were identified in 722 (65%) of the 1104 patients who met the criteria for inclusion in the study. Female patients were less likely to have a meniscus injury than male patients were (56% compared with 71%), and male patients were more likely to have combined medial and lateral meniscus injuries than female patients were (20% compared with 11%). Patients with a surgical delay of less than three months were less likely to have a medial meniscus injury (8% compared with 19%). Femoral articular cartilage injuries were identified in 472 patients (43%). Patients who were twenty-five years of age or older were more likely to have multiple cartilage lesions throughout the knee (7.7% compared with 1.3%) and to have more isolated medial femoral condyle lesions (24.2% compared with 13.3%). Patients with a surgical delay of more than one year were more likely to have a lesion (60% compared with 47% for all others), and a surgical delay of more than one year resulted in a greater proportion of large and grade-3 lesions of the lateral femoral condyle. Female patients had a greater proportion of grade-1 lesions of the medial femoral condyle (29% compared with 16%), whereas male patients had a greater proportion of grade-3 and 4 lesions of the medial femoral condyle (49% compared with 35%). In patients who were thirty-five years of age or older, meniscus injuries were more frequent and were located more frequently on the medial side; femoral articular cartilage lesions were also located more frequently on the medial side. CONCLUSIONS Increased age, male sex, and increased surgical delay all increase the frequency and severity of injuries of the meniscus and/or articular cartilage after an anterior cruciate ligament tear.

Abstract
Two hundred and five patients with ACL rupture, who had been diagnosed pre-operatively by either MRI scan or knee arthroscopy, had reconstructions between 2003 and 2007. The diagnostic meniscal findings were compared with those at reconstruction, and any further damage along with time from diagnosis to reconstruction was recorded. Those patients with no meniscal damage at the time of diagnosis, and who had no further damage at surgery had a median time of 6 months. This time was significantly different from those with no meniscal damage at diagnosis, but who were found subsequently to have sustained damage to one meniscus, when the median time was 11 months (P = 0.0017) or both menisci, when the median time was 32 months (P = 0.0184). For patients with solitary ACL rupture undergoing a trial of conservative management, an early and thorough assessment of functional stability is essential. If the instability is unacceptable, the patient should be informed of the time dependent risk to the menisci with further delay to surgical reconstruction.

Abstract
Xenogeneic porcine small intestinal submucosa (SIS) is a natural, biodegradable matrix that has been successfully used as a scaffold for repair of tissue defects. The goal of this study was to compare a collateral ligament transection surgically reconstructed with an anchored SIS ligament to a sham-operated control procedure for the correction of joint laxity using an equine model. Ten metacarpophalangeal joints from 10 horses had complete transection of the lateral collateral ligament. In 6 horses, the collateral ligament was reconstructed with a multilaminate strip of SIS anchored with screws into bone tunnels proximal and distal to the joint. The sham controls had similar screws, but no SIS placed. Clinical compatibility and effectiveness were evaluated with lameness, incisional quality, and joint range of motion, circumference and laxity. Ligament structure and strength was quantified with serial high resolution ultrasound, histology, and mechanical testing at 8 weeks. Surgical repair with SIS eliminated joint laxity at surgery. SIS-treated joints had significantly less laxity than sham treatment at 8 weeks (p < 0.001). SIS-treated ligaments demonstrated a progressive increase in repair tissue density and fiber alignment that by week 8 were significantly greater than sham-treated ligament (p < 0.03). SIS-repaired ligament tended to have greater peak stress to failure than sham-treatment (p < 0.07). Cellularity within the ligament repair tissue and inflammation within the bone tunnel was significantly greater in the SIS-treated limbs (p < 0.017). Within the first 8 weeks of healing, SIS implanted to reinforce collateral ligament injury was biocompatible in the joint environment, restored initial loss of joint stability, and accelerated early repair tissue quality. SIS ligament reconstruction might provide benefit to early ligament healing and assist early joint stability associated with ligament injury.

Abstract
Anterior cruciate ligament (ACL) injuries often lead to significant functional impairment, and are associated with increased risk for induction of degenerative joint disease. However, few studies have described the effect of ligament transection on the remaining intact knee ligaments. This study sought to determine specifically what impact combined ACL/medial collateral ligament (MCL) transection had on the remaining intact knee ligaments, particularly from the histological, biochemical, and molecular perspectives. Twenty weeks post-ACL/MCL transection, the cut ends of sheep MCLs were bridged by scar, while the posterior cruciate ligaments (PCLs) and lateral collateral ligaments (LCLs) seemed gross morphologically normal. Water content and cell density increased significantly in the MCL scars and the intact PCLs but were unchanged in the LCLs. Collagen fibril diameter distribution was significantly altered in both MCL scar tissue and uninjured PCLs from transected joints. MMP-13 mRNA levels in MCL scars and PCLs from ligament transected joints were increased, while TIMP-1 mRNA levels were significantly decreased in the PCLs only. This study has shown that some intact ligaments in injured joints are impacted by the injury. The joint appears to behave like an integrated organ system, with injury to one component affecting the other components as the "organ" attempts to adapt to the loss of integrity.
