Abstract
Concomitant cruciate and meniscus injuries of the knee are generally associated with acute trauma and commonly treated with surgical intervention. Comorbidities (simultaneous presence of two or more medical conditions) may be acquired from changes in activity levels and lifestyle after an injury and/or treatment. This study aimed to compare differences in comorbidity proportions between surgical and nonsurgical approaches in Military Health System beneficiaries who had concurrent cruciate and meniscus injuries. The retrospective case control design included 36-month data that were analyzed to reflect 12 months prior to injury/surgery and 24 months after injury/surgery. A comparison of differences within and between groups in surgical and nonsurgical approaches was calculated and logistic regression was used to determine if surgery increased or decreased the odds of comorbidities at 24 months. In our sample of 2,438 individuals with concurrent meniscus and cruciate injury, 79.1% (n = 1,927) received surgical intervention and 20.9% (n = 511) elected for nonoperative management. All comorbidities demonstrated significant within-group differences from pre- to postsurgery for those with a surgical intervention; approximately, half the comorbidities increased (i.e., concussion or traumatic brain injury, insomnia, other sleep disorders, anxiety, posttraumatic stress disorder, and tobacco abuse disorder), whereas the other half decreased (i.e., chronic pain, apnea, cardiovascular disease, metabolic syndrome, mental health other, depression, and substance abuse disorders). The odds of acquiring a comorbid diagnosis after surgery reflected the bivariate comparisons with half increasing and half decreasing in odds. To our knowledge, this is the first study to explore comorbidity changes with a control group for individuals with concurrent meniscus and cruciate injuries.

One-Third of Meniscal Tears Are Repairable: An Epidemiological Study Evaluating Meniscal Tear Patterns in Stable and Unstable Knees. Arthroscopy 2019; 35:857-863. [PMID: 30704886 DOI: 10.1016/j.arthro.2018.08.051] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Revised: 08/19/2018] [Accepted: 08/22/2018] [Indexed: 02/02/2023]
Abstract
PURPOSE To analyze, in a long series of patients with knee injuries, the meniscal tear patterns in both stable and unstable knees to ascertain the exact proportion of such injuries that could have been repaired. METHODS A descriptive cross-sectional study was undertaken by reviewing the clinical reports of arthroscopic knee operations carried out in 1 hospital. A total of 2,066 consecutive patients were included in the study. An analysis of clinical and anatomical data of knee lesions, including the shape of the meniscal tears and the surrounding injuries, was performed. RESULTS Out of all meniscal tears, 34.9% were found to be repairable, a figure that rose to 55.6% in those tears accompanied by anterior cruciate ligament injuries; 37% of meniscal tears in male patients were repairable, and 28% in their female counterparts; 38.2% of medial meniscal tears were repairable and 30.6% in their lateral counterparts. The most frequently encountered injury was the complex tear (46.9%). CONCLUSIONS Our study concludes that, according to current standard indications, 34.9% of all meniscal injuries offer the potential for repair. Where the injury is also accompanied by anterior cruciate ligament damage, the proportion of repairable tears rises to 55.6%. This information should increase the interest for meniscal preservation in the future. LEVEL OF EVIDENCE Level IV, case series.

Abstract
BACKGROUND Although numerous studies have assessed arthroscopic repair of meniscal tears, no study has described the repair of partial- or full-thickness longitudinal medial meniscal tears using single or double vertical sutures. PURPOSE To present the intermediate-term results of medial meniscal tears repaired with single or double vertical sutures. STUDY DESIGN Case series; Level of evidence, 4. METHODS The authors evaluated the results of 112 longitudinal medial meniscal tears treated with inside-out single or double vertical sutures, with or without anterior cruciate ligament (ACL) reconstruction, based on the clinical resolution of symptoms, the Lysholm knee scoring scale, and the Tegner activity scale. Re-examination was also performed by magnetic resonance imaging after the repair. The length of the tears was evaluated arthroscopically. Eighty-five tears of 112 were >2 cm in length, and 27 were tears ≤2 cm. Eighty-nine (79.4%) of the 112 repairs were performed in conjunction with ACL reconstructions, and the remaining 23 (20.6%) repairs were performed in ACL-intact knees. The tear type of the menisci in our study was full thickness in 66 (58.9%) cases and partial thickness in 46 (41.1%) cases. Double vertical sutures were used for full-thickness tears, and single vertical sutures were used for partial-thickness tears. RESULTS The cases were evaluated after a mean follow-up duration of 49.3 months (range, 12-88 months). Clinical and radiological examination results determined that 99 (88.4%) meniscal repairs had healed, and the remaining 13 cases (10.6%) were considered to be failures. The healing rate of the full-thickness group was 80.3%, while in the partial-thickness group, the rate was 100%. The mean Lysholm score improved significantly from a preoperative value of 63.8 to a postoperative value of 89.5 (P < .001). The mean Tegner activity score was 3.3 preoperatively and 6.7 postoperatively (P < .001). Logistic regression analysis found that concurrent ACL reconstruction, tear length, and smoking as factors had a significant effect on meniscal healing. CONCLUSION Single or double vertical sutures using the inside-out technique provide a high rate of healing in longitudinal medial meniscal tears.

Abstract
The treatment of meniscal tears continues to evolve. A few years ago most tears were treated with total meniscectomy, which evolved to partial meniscectomy and then to meniscal repair. The purpose is to preserve as much of the menisci as possible, to maintain their potential biomechanical properties, and to preserve normal knee function. Different repair techniques have been used many of them involving both vertical and horizontal sutures. We are proposing an inside-out meniscal repair technique with cross-shaped stitches that provides a 4-point fixation construct.

Abstract
PURPOSE To study the long-term outcome of patients who have undergone inside-out, vertical stacked mattress suture repair of meniscal tears combined with anterior cruciate ligament (ACL) reconstruction. METHODS From a database of ACL reconstructed patients, consecutive patients undergoing concomitant meniscal repair and ACL reconstruction between 1991 and 1999 were identified. Patients with previous ACL or meniscal pathology were excluded. Two age- and sex-matched cohorts who had undergone combined ACL reconstruction and menisectomy and who had undergone ACL reconstruction with normal menisci were identified for comparison. Outcome scoring included IKDC and Lysholm scores for the meniscal repair group. Two sample t-tests and chi-square tests were used to compare the IKDC subjective scores, with a minimum level of significance set at 5% (P = 0.05). RESULTS Fourty-four patients were identified for analysis with a median follow-up of 10 years (7.7-12.6). Patients undergoing ACL reconstruction combined with meniscal repair had a mean IKDC of 84.2 compared with a mean score of 70.5 (P = 0.008) in patients who had undergone menisectomy and 88.2 (P = 0.005) in patients with intact menisci. 86.2% of patients with ACL reconstruction and meniscal repair had Lysholm score of between 80 and 100%. Sixty-nine percent follow-up was achieved. Survival analysis by life table method shows a best case of 89% 10-years survival. CONCLUSIONS This study demonstrates that good long-term outcomes can be obtained in patients up to over 12 years after combined ACL reconstruction and meniscal repair. Improved functional scores can be achieved when compared with ACL reconstruction and menisectomy. The authors advocate repair of meniscal tears during ACL reconstruction unless there is complex tearing, radial tearing or plastic deformation of the remaining meniscus. LEVEL OF EVIDENCE III.

Abstract
PURPOSE The aim of this study was to show that repair of posterior radial tears and horn detachments of the lateral meniscus is possible and to assess the outcomes. METHODS A retrospective review of 24 patients who had repair of a posterior defunctioning tear of the lateral meniscus combined with anterior cruciate ligament reconstruction was undertaken. Patients completed a follow-up postal questionnaire that included Lysholm, subjective International Knee Documentation Committee (IKDC), and Tegner scoring systems. RESULTS Eight patients had suture repair of a lateral meniscal radial tear. The mean Lysholm, IKDC, and Tegner scores were 86.9 (SD, 11.6), 81.6 (SD, 13.9), and 5.8 (SD, 2.7), respectively, at a mean follow-up of 70.5 months (range, 29.0 to 168.0 months). Subsequent arthroscopy in 2 patients confirmed meniscal healing. Sixteen patients underwent a posterior horn reattachment. The mean Lysholm, subjective IKDC, and Tegner scores were 86.1 (SD, 13.3), 84.3 (SD, 17.0), and 6.5 (SD, 2.1), respectively, at a mean follow-up of 53.6 months (range, 26.0 to 116.0 months). Three patients had subsequent magnetic resonance imaging and/or arthroscopy that indicated meniscal healing. Two further patients had reinjury, and magnetic resonance imaging and/or arthroscopy showed that their repairs had failed. CONCLUSIONS Posterior radial tears that extend to the capsule and posterior horn detachments of the lateral meniscus are frequently amenable to repair. In this study 22 of 24 repairs functioned successfully over a mean follow-up of 58.6 months (range, 26.0 to 168.0 months). LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
BACKGROUND The incidence of osteoarthritis after anterior cruciate ligament reconstruction is disturbingly high, with reports of nearly 50% of patients developing mild to moderate osteoarthritis 6 years after surgery. Few studies have assessed the factors involved in the development of osteoarthritis. HYPOTHESIS The following 10 factors will be found to be predictive of osteoarthritis: meniscectomy, chondral damage, patellar tendon grafting, age at surgery, time delay between injury and surgery, type and intensity of postsurgery sport, quadriceps strength, hamstring strength, quadriceps-to-hamstring strength ratio, and residual joint laxity. STUDY DESIGN Cohort study (prognosis); Level of evidence, 1. METHODS Fifty-six subjects with anterior cruciate ligament reconstruction were followed for 6 years after surgery. Assessment included KT-1000 arthrometer testing, isokinetic strength testing, a return-to-sport questionnaire, and a radiograph assessment. A discriminant analysis was performed to assess which of the 10 factors could discriminate between those patients who developed tibiofemoral and patellofemoral osteoarthritis and those who did not. RESULTS Five factors were found to be predictive of tibiofemoral osteoarthritis. Meniscectomy (r = .72) and chondral damage (r = .41) were the strongest discriminators, followed by patellar tendon grafting (r = .37) (chi(2) [7, n = 56] = 25.48; P = .001). Weak quadriceps (r = .39) and low quadriceps-to-hamstring strength ratios (r = .6) were very close discriminators (chi(2) [8, n = 42] = 15.02; P = .059). For patellofemoral osteoarthritis, meniscectomy (r = .45), chondral damage (r = .75), and age at surgery (r = .65) were predictors or close predictors (chi(2) [7, n = 54] = 13.30; P = .065). CONCLUSION As not all 10 factors studied were predictive of osteoarthritis, the hypothesis was only partially proven. Preventing further meniscal and chondral damage in patients with anterior cruciate ligament deficiency is critical. Grafting using the hamstring tendons and restoration of quadriceps-to-hamstring strength balance are associated with less osteoarthritis.

Abstract
This study aimed to determine the incidence of meniscal tears and describe the tear morphology and selected treatment in patients undergoing anterior cruciate ligament (ACL) reconstruction. We also will discuss the potential market for future tissue engineering aimed at preserving meniscal function. A multicenter cohort of 1014 patients undergoing ACL reconstruction between January 2002 and December 2003 was evaluated. Data on patient demographics, presence of a meniscus tear at time of ACL reconstruction, tear morphology, and meniscal treatment were collected prospectively. Meniscal tears were categorized into 3 potential tissue engineering treatment strategies: all-biologic repair, advanced repair, and scaffold replacement. Of the knees, 36% had medial meniscal tears and 44% had lateral meniscal tears. Longitudinal tears were the most common tear morphology. The most frequent treatment method was partial meniscectomy. Thirty percent of medial meniscal tears and 10% of lateral meniscal tears are eligible for all-biologic repair; 35% of medial meniscal tears and 35% of lateral meniscal tears are eligible for an advanced repair technique; and 35% of medial meniscal tears and 55% of lateral meniscal tears are eligible for scaffold replacement. Although meniscal preservation is generally accepted in the treatment of meniscal tears, most tears in this cohort were not repairable, despite contemporary methods. The results of this cohort will hopefully stimulate and focus future research and development of new tissue engineering strategies for meniscus repair.

Abstract
We report a case of acute ACL injury with an unusual lateral meniscal tear pattern. The entire posterior horn of the lateral meniscus was avulsed from its attachments while remaining in continuity with the body of the meniscus. It was displaced posteriorly and laterally to the popliteus tendon so that it was not immediately visible at the time of arthroscopy. This type of displacement of the posterior horn of the lateral meniscus is difficult to identify at arthroscopy and has not previously been described in the literature to our knowledge. We recommend to surgeons who encounter an absent posterior horn of the lateral meniscus to consider this injury pattern.

Abstract
PURPOSE To evaluate the stability and arthrosis of the knee 10 to 15 years after arthroscopic-assisted anterior cruciate ligament (ACL) reconstruction with patellar tendon graft. METHODS From July 1986 to March 1991, 82 patients underwent arthroscopic-assisted ACL reconstruction with patellar tendon graft. Of these, 62 returned for follow-up evaluation between November 2000 and April 2001. Four different physicians, blinded to each other's examination findings, evaluated the radiologic as well as surgical results according to the International Knee Documentation Committee criteria and the Lysholm knee scoring scale. RESULTS There were 47 male and 15 female patients. The mean period between injury and surgery was 16 months (range, 2 weeks to 8 years). Results of radiographs were compared with the finding of meniscal lesions during surgery and with International Knee Documentation Committee test results. A statistically significant association (P < .0001) was found between medial or lateral arthrosis of the knee and meniscal injury. In all patients the presence of tears in both menisci was associated with osteoarthrosis in both compartments (medial and lateral). CONCLUSIONS In patients who underwent arthroscopic-assisted ACL reconstruction with patellar tendon graft who also had medial or lateral meniscectomy (or both), arthrosis of the respective compartments developed by 10 to 15 years after reconstruction. Meniscectomy was also associated with poorer results on objective tests of knee function, even with a stable knee joint. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
Preservation of the menisci is increasingly emphasized in orthopedic care of the knee. Techniques are rapidly emerging that allow easier accomplishment of this goal. In particular, the development of all-inside arthroscopic meniscal repair devices has facilitated more ready repair. A number of laboratory and clinical studies have examined these devices and comparisons with more traditional techniques have been made. Numerous reports of potential complications from these new technologies have also been described in the literature. This review covers the current options for treatment of meniscal repair, laboratory and clinical data, and also potential complications.

Abstract
BACKGROUND Numerous studies have investigated the biomechanical properties of meniscal repair techniques. One of the most commonly discussed parameters is the failure load in the axis of insertion, although little is known about the distraction forces actually occurring at repaired bucket-handle lesions. HYPOTHESIS There are clinically relevant distraction forces on repaired meniscus bucket-handle lesions. STUDY DESIGN Controlled laboratory study. METHODS Meniscus bucket-handle lesions were created and repaired in human cadaveric knees with a vertical suture made from a braided steel wire. A small-sized load sensor was connected to the wire at the periphery of the meniscus. The distraction forces acting on the lesion were measured at different knee joint angles (0 degrees -120 degrees of flexion) with internal and external rotation and with and without weight loading. Forces in excess of 10 N were considered to have clinical relevance. RESULTS Mean forces on the meniscus repair ranged from 1.64 to 4.72 N. Irrespective of the modalities (ie, different flexion angles, weight load, direction of rotation), it was found that the forces were well below the cutoff value of 10 N (P < .01). Increasing flexion angles generally did not cause an increase in distraction forces. CONCLUSION The data suggest that distraction forces are not the primary factor in the mechanical stability of meniscal repair. It must therefore be assumed that other factors such as shear forces are of greater significance. CLINICAL RELEVANCE The results may help to validate the biomechanical properties of different meniscal repair techniques.

Abstract
BACKGROUND A new generation of flexible all-inside meniscal repair devices is available, but clinical studies with these devices are lacking. HYPOTHESIS The RapidLoc has an intermediate-term meniscal healing rate that is equivalent to literature reports of inside-out suture technique in patients undergoing concurrent anterior cruciate ligament reconstruction. STUDY DESIGN Case series; Level of evidence, 4. METHODS Retrospective analysis was performed for 75 meniscal tears in 66 consecutive patients undergoing anterior cruciate ligament reconstruction who underwent meniscal repair with the RapidLoc. Patients with at least 2 years' follow-up were evaluated for symptoms suggestive of a meniscal tear and were assessed with the International Knee Documentation Committee form and the Knee Disorders Subjective History visual analog scale. Subjects were asked to return for a clinical examination to include evaluation for an effusion and joint line tenderness as well as McMurray test and KT-1000 arthrometry readings. Patients with symptoms consistent with meniscal repair failure underwent magnetic resonance arthrography and repeat arthroscopy. RESULTS Twenty patients with 21 meniscal tears were excluded, resulting in 54 meniscal tears in 46 patients. At a mean follow-up of 34.8 months, the clinical success rate for meniscal repair was 90.7% (49/54), with 5 failures requiring meniscectomy. Univariate analysis revealed predictive variables for failure: bucket-handle configuration, multiplanar tears, tear length greater than 2 cm, and chronicity longer than 3 months. Non-predictive variables included compartment, zone, ligament graft choice, gender, age, follow-up, and visual analog scale score. Analysis of healed patients revealed a negative correlation between chronicity of tear and International Knee Documentation Committee score. CONCLUSIONS The RapidLoc has an acceptable intermediate-term clinical healing rate in patients undergoing concurrent anterior cruciate ligament reconstruction. Predictive variables for failure should be considered during operative decision making.

Abstract
PURPOSE The purpose of this study was to evaluate the midterm healing rate and any adverse events from meniscus repair using the BioStinger meniscus repair device (Linvatec, Largo, FL). METHODS A retrospective review of a consecutive series of meniscal repairs performed by a single surgeon using the BioStinger was conducted. The BioStinger is cannulated, made of molded poly L-lactic acid, and inserted over a needle into the meniscus tissue. Clinical results and adverse events were noted, and Lysholm, Tegner, Cincinnati, and International Knee Documentation Committee (IKDC) activity scores were obtained on all patients. RESULTS Forty-one patients underwent 41 meniscal repairs with an average follow-up of 38.6 months (range, 24 to 69 months); 35 meniscus repairs were performed in conjunction with anterior cruciate ligament reconstruction and 6 in stable knees. Tears repaired were peripheral, posterior horn tears with an average length of 2 cm. Clinical evidence of meniscal healing was observed in 95% at the time of last follow-up. Six second-look arthroscopies were performed and 2 failures were found. All other patients were symptom free. At follow-up, the mean Tegner score was 6.1 (2.8 preoperative), IKDC activity score was 3.3 (2.1 preoperative), Lysholm score was 90.6 (48.7 preoperative), and the mean Cincinnati score was 86.7 (41.3 preoperative). Four patients had peripheral migration of the device without skin tenting or perforation; 3 underwent removal of the BioStinger from the soft tissues and the other resolved after 12 months. CONCLUSIONS The midterm clinical success rate was 95% using the BioStinger device. Adverse events were observed in few cases. LEVEL OF EVIDENCE Level IV, cases series.

Abstract
BACKGROUND An increased awareness of the degenerative changes that occur in the knee after meniscectomy has led to efforts to salvage the injured meniscus. Numerous devices have been developed in an effort to provide the dual benefits of a durable meniscal repair and minimal invasiveness. HYPOTHESIS The Meniscus Arrow is comparable to conventional inside-out suture repair in accomplishing long-term healing of meniscal tears. STUDY DESIGN Case series; Level of evidence, 4. METHODS This study is an extended follow-up of an original series of 32 patients with outcomes analysis. All patients underwent meniscal repair with exclusive use of the arrow. All repairs were performed in the context of a concomitant anterior cruciate ligament reconstruction. Follow-up assessment included physical examination, arthrometry, the International Knee Documentation Committee instrument, and the Knee Disorders Subjective History visual analog scale. Intermediate follow-up at a mean of 2.3 years yielded a success rate of 90.6%. The mean follow-up in the present study has been extended to 6.6 years. RESULTS The extended follow-up analysis revealed a substantial attrition in the success rate of this series of patients undergoing meniscal repair with the arrow. A 90.6% success rate at a mean follow-up of 2.3 years deteriorated to 71.4% at 6.6 years. CONCLUSION This study provides the longest follow-up in the literature of any of the all-inside meniscal repair implants. The Meniscus Arrow demonstrated long-term meniscal healing rates inferior to those found in the literature for inside-out suture repair techniques.
