AbstractThe literature contains very limited articles wherein the treatment results of bucket-handle meniscal tears according to various types are evaluated and wherein results for repair of chronic tears are discussed. The objective of this study is a clinical and radiologic evaluation of arthroscopic repair for patients suffering flipped, neglected chronic bucket-handle meniscal tear in the intercondylar notch. A total of 26 patients were evaluated retrospectively. The mean age at the time of surgery was 27 years (range, 16–44). Mean period from meniscal injury to surgery was 28 months (range, 4–96). The mean follow-up period was 31 months (range, 11–67). During the follow-up, the patients were evaluated clinically, functional scores from the International Knee Documentation Committee (IKDC), Lysholm, and Tegner as well as magnetic resonance imaging (MRI). The mean preoperative Lysholm score of 24 increased to 85 postoperatively. Mean IKDC score was 56.3 preoperatively and 84.5 postoperatively. The mean Tegner score of 3.4 increased to 5.6 postoperatively. Mean Lysholm, IKDC, and Tegner scores in the first group were 84, 74, and 5.1, respectively, and in the anterior cruciate ligament (ACL) reconstruction group; 86, 85.9, and 5.8. While 20 (77%) out of 26 patients had none of the clinical findings, 6 patients (23%) presented with these findings. Postoperative MRI assessment revealed meniscal healing in 21 patients (27% complete, 54% partial healing) and no healing in 5 patients (19%). A clinical healing rate of 77% and a radiological healing rate of 81% along with statistically significant increases in Lysholm, IKDC, and Tegner scores prove that the repair option is effective for neglected, chronic bucket-handle meniscal tears flipping to the intercondylar notch. This study showed that good results could be achieved with the repair of neglected, chronic period bucket-handle meniscal tears flipping to the intercondylar notch, whether with an accompanying ACL tear or not.

Background: There are limited data comparing the outcomes of all-inside versus inside-out meniscal repair techniques. Purpose: To assess failure rates and clinical outcomes after the surgical repair of bucket-handle meniscal tears utilizing either an all-inside or inside-out technique. Study Design: Cohort study; Level of evidence, 3. Methods: Patients with bucket-handle meniscal tears undergoing all-inside or inside-out repair at a single institution between 2003 and 2013 were analyzed. A total of 28 mensici repaired utilizing second-generation all-inside suturing devices and 42 menisci repaired using an inside-out technique were eligible for inclusion. Rigorous propensity matching was performed on the basis of age, sex, tear laterality, rim width, and concomitant anterior cruciate ligament reconstruction (ACLR), resulting in a total of 40 patients equally distributed between the 2 repair techniques for comparison. Retear-free survival as well as preoperative and postoperative International Knee Documentation Committee (IKDC) and Tegner scores and physical examination findings were subsequently analyzed. Results: Twenty patients who underwent all-inside repair (14 male; mean age, 23.7 ± 6.7 years) were successfully propensity matched to 20 patients who underwent inside-out meniscal repair (15 male; mean age, 22.5 ± 7.6 years), with a mean retear-free follow-up of 4.4 years (range, 2.5-7.4 years). Four (20%) all-inside repairs and 4 (20%) inside-out repairs failed over the course of follow-up ( P > .999), with a mean time to failure of 2.7 years (range, 1.3-4.4 years) and 5.0 years (range, 0.8-7.5 years), respectively ( P = .25). Increasing patient age trended toward a decreased clinical retear rate, independent of the repair technique (hazard ratio, 0.86; P = .056). There were no significant differences in the Tegner scores, IKDC scores, or range of motion between the groups as a whole or when subcategorizing by age, sex, body mass index, tear complexity, rim width, isolated versus concomitant ACLR, or medial- versus lateral-sided repair. There were no complications in the all-inside group, while there was a 10% rate of minor complications in the inside-out group ( P = .49). Conclusion: Overall, satisfactory clinical outcomes are achievable at short-term to midterm follow-up with both inside-out and all-inside repair techniques of bucket-handle meniscal tears in rigorously matched patients with similar meniscal tear patterns.

Background: Large bucket-handle meniscal tears in knees with chronic anterior cruciate ligament deficiency have been considered avascular and, thus, irreparable. Hypothesis: The rate of meniscal healing is higher than previously reported. Study Design: Prospective cohort study. Methods: Fifty-nine patients underwent staged surgical procedures of meniscal repair followed at an average of 77 ± 58 days by ligament reconstruction once full range of motion was obtained. Results: Fifty-two patients with 55 meniscal repairs were available for follow-up. At reconstruction, 30 menisci (55%) appeared healed; 19 (34%), partially healed; and 6 (11%) showed no healing (only 4 were removed). Of 43 tears in the white-on-white zone, 21 appeared healed; 17, partially healed; and 5 showed no healing. Of 11 in the red-on-white zone, 8 appeared healed; 2, partially healed; and 1 showed no healing. One meniscal tear in the red-on-red zone appeared healed. At an average follow-up of 4.3 ± 3.1 years, 36 of the 43 (83.7%) white-on-white meniscal repairs remained asymptomatic; all repairs in the other zones remained asymptomatic. Conclusion: Locked bucket-handle meniscal tears heal at a high rate when repaired as an isolated procedure, even when full weightbearing and activity before reconstruction is allowed and when the tear is in the white-on-white zone.

Background: Anterior cruciate ligament (ACL) injury is one of the most frequent orthopaedic injuries and reasons for time loss in sports and carries significant implications, including posttraumatic osteoarthritis (OA). Instability associated with ACL injury has been linked to the development of secondary meniscal tears (defined as tears that develop after the initial ACL injury). To date, no study has examined secondary meniscal tears after ACL injury and their effect on OA and arthroplasty risk. Purpose: To describe the rates and natural history of secondary meniscal tears after ACL injury and to determine the effect of meniscal tear treatment on the development of OA and conversion to total knee arthroplasty (TKA). Study Design: Cohort study; Level of evidence, 3. Methods: A geographic database of >500,000 patients was reviewed to identify patients with primary ACL injuries between January 1, 1990, and December 31, 2005. Information was collected with regard to ACL injury treatment, rates/characteristics of the secondary meniscal tears, and outcomes, including development of OA and conversion to TKA. Kaplan-Meier and adjusted multivariate survival analyses were performed to test for the effect of meniscal treatment on survivorship free of OA and TKA. Results: Of 1398 primary ACL injuries, the overall rate of secondary meniscal tears was 16%. Significantly lower rates of secondary meniscal tears were noted among patients undergoing acute ACL reconstruction within 6 months (7%) as compared with patients with delayed ACL reconstruction (33%, P < .01) and nonoperative ACL management (19%, P < .01). Of the 235 secondary meniscal tears identified (196 patients), 11.5% underwent repair, 73% partial meniscectomy, and 16% were treated nonoperatively. Tears were most often medial in location (77%) and complex in morphology (56% of medial tears, 54% of lateral tears). At the time of final follow-up, no patient undergoing repair of a secondary meniscal tear (0%) underwent TKA, as opposed to 10.9% undergoing meniscectomy and 6.1% receiving nonoperative treatment ( P = .28). Conclusion: Secondary meniscal tears after ACL injury are most common among patients undergoing delayed surgical or nonoperative treatment of their primary ACL injuries. Secondary tears often present as complex tears of the medial meniscus and result in high rates of partial meniscectomy.

Objectives: The aim of this study was to evaluate clinical and functional outcomes following the arthroscopic medial meniscal repair. Patients and methods: A total of 50 patients (42 males, 8 females; mean age: 32.9±7.6 years; range, 17 to 48 years) who underwent arthroscopic repair for longitudinal and bucket-handle medial meniscal tears between March 2005 and October 2011 were retrospectively evaluated. The patients were divided into two groups as those having a longitudinal tear (patient group, n=31) and having a bucket-handle tear (control group, n=19). Preoperative and final follow-up functional outcomes were evaluated using the Lysholm Knee Score (LKS), International Knee Documentation Committee (IKDC) score, Tegner Activity Scale (TAS) score, and Knee Injury and Osteoarthritis Outcome Score (KOOS). Results: The mean follow-up was 61.7±22.8 (range, 36 to 110) months. The mean preoperative LKS, IKDC score, TAS, and KOOS scores were significantly improved at the final postoperative follow-up (p<0.05). There was no significant difference in functional outcome scores between longitudinal and bucket-handle repairs (p>0.05), and isolated repairs and concomitant meniscal repair and anterior cruciate ligament reconstruction (p>0.05). Conclusion: Arthroscopic meniscal repair provides similar mid-term functional and clinical outcomes for longitudinal and bucket-handle medial meniscal tears. Concomitant meniscal repair does not seem to affect meniscal healing.

Traumatic tears of the meniscus are well reported in the literature. Rarely, bilateral meniscal tears occur. A PubMed search found that only three cases of bilateral medial meniscus bucket handle type tears have been reported. Treatment options range from partial meniscectomy to repair of the meniscal tear. Repair is reported to be more successful in the vascular red-red or red-white zones. We present the case of a 23-year-old female who sustained simultaneous bilateral medial meniscus bucket handle type tears in an automobile accident. She was treated in a staged fashion with knee arthroscopy. Her meniscus tears were both found to be in the vascularized zone and meniscal tear repair was conducted. At two weeks postoperatively, she had excellent resolution of her symptoms and has returned to pain-free weight-bearing. She has remained pain-free at six-month follow-up.

Background: Full-thickness radial meniscal tears render the meniscus nonfunctional and have historically been treated with partial meniscectomy. As preservative techniques evolve for radial repair, comparisons with other tear patterns are necessary to evaluate repair efficacy and prognosis. Purpose: To assess clinical outcomes and reoperation rates of radial meniscal repair and to compare them to bucket-handle meniscal repair. Study Design: Cohort study; Level of evidence, 3. Methods: Radial and bucket-handle meniscal tears without concurrent root injuries undergoing surgical repair at a single institution between 2007 and 2015 were analyzed, including both all-inside and inside-out suturing techniques. Propensity matching was performed on the basis of age at surgery, sex, meniscus laterality, body mass index (BMI), and concomitant anterior cruciate ligament reconstruction (ACLR) using a comparison pool of 70 bucket-handle repairs. Reoperation-free survival rates and Tegner, visual analog scale (VAS) for pain, and International Knee Documentation Committee (IKDC) scores were analyzed. Results: Twenty-four patients (18 male, 6 female; mean age, 22.8 ± 11.9 years) who underwent repair of a radial meniscal tear were followed for a mean of 3.5 years (range, 2.0-6.3 years). Significant postoperative improvements in VAS scores at rest and with use and IKDC scores were noted postoperatively ( P < .001). Five patients (20.8%) required a reoperation. Subsequently, 18 patients with radial tears (mean age, 19.1 ± 9.1 years; 12 male; mean BMI, 27.0 ± 6.2 kg/m2; 3 medial; 11 ACLR) were propensity matched to 18 patients with bucket-handle tears (mean age, 20.8 ± 5.1 years; 13 male; mean BMI, 25.0 ± 3.5 kg/m2; 3 medial; 11 ACLR). The matched radial and bucket-handle groups demonstrated similar ( P = .17) reoperation-free survival rates at 2 years (88.9% and 94.4%, respectively) and 5 years (77.8% and 87.7%, respectively). VAS and IKDC scores improved significantly after surgery ( P < .001), with no difference noted between the groups ( P ≥ .17). Patients with radial and bucket-handle meniscal repairs achieved mean postoperative Tegner scores (6.6 and 6.6, respectively) not significantly different from their preinjury levels (6.9 and 6.7, respectively) ( P ≥ .32). Conclusion: Satisfactory clinical outcomes are achievable for radial meniscal tear repair at short-term follow-up. In a robustly matched comparison, radial and bucket-handle meniscal tears demonstrate similar improvements in VAS and IKDC scores, restoration of preoperative Tegner scores, and acceptable reoperation rates. Full-thickness radial meniscal tears should be considered for repair.

AbstractAnterior cruciate ligament (ACL) reconstruction represents one of the most successful orthopedic surgical procedures. Nevertheless, ACL revisions are still very frequent, with a small but relevant number of failures. The purpose of this study is to analyze the failure causes and the clinical outcomes of patients who underwent a re-revision ACL reconstruction. Between January 2009 and December 2017, 263 ACL revisions were performed by a single senior surgeon. Seventeen patients (12 males and 5 females) underwent re-revision ACL reconstruction meeting the inclusion criteria. The mean age was 28.4 years (range, 19–41 years). Before the re-revision, the patients were evaluated preoperatively and after a mean follow-up of 29 months (range, 13–58 months). Assessment included subjective and objective evaluations (Lysholm and International Knee Documentation Committee [IKDC]), KT-2000 arthrometer, radiographic study, and preoperative computed tomography scan. Five patients showed a too anterior previous femoral tunnel and seven a too vertical and posterior tibial tunnel; eight meniscal tears were found. Five patients had grade III–IV according to Outerbridge cartilage lesions. IKDC showed a statistically significant improvement (A + B 35%, C + D 65% preop, A + B 82%, C + D 18% postop, odds ratio: 0.1169; p = 0.0083). The mean Lysholm score ranged from 43 ± 9 to 87 ± 7 (p < 0.001). The KT-2000 arthrometer showed a statistically significant improvement from a mean of 5.8 ± 1.4 to 1.5 ± 1.1 (p < 0.001) at last follow-up. Out of 17 patients, only 4 returned to sports activity at the same preinjury levels. Postoperatively at the last follow-up after last revision surgery, no osteoarthritis evolution was observed. This study showed good clinical and radiological results after the last revision ACL surgery in patients with multiple failures of ACL reconstruction but only one-fourth of the patients returned to the same preoperative sport level. Traumatic events, technical errors, and untreated peripheral lesions are the main causes of multiple previous failures; the worst clinical outcomes were found in the patients with high grade of chondral lesions.

AbstractThe aim of this study was to evaluate the success of the all-inside repair technique for medial bucket-handle meniscus tear (BHMT) and the factors affecting healing. A total of 36 patients with BHMT who were operated between 2012 and 2018 and completed final follow-up examinations were included in the study. Functional evaluation was made with the International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score. Healing was evaluated on magnetic resonance imaging (MRI) slices. The patients were evaluated with respect to the effect on healing of factors such as demographic data, body mass index (BMI), smoking status, anterior cruciate ligament tear reconstruction (ACLTR) applied at the same time as BHMT repair, and the tear being chronic or acute. The mean age of the patients was 28.6 ± 8.6 years (range,18–46 years), the mean follow-up period was 25.8 ± 13.9 months (range, 13–59 months), and BMI was mean 25.6 ± 3.5 kg/m2 (range, 20.1–30.5 kg/m2). The meniscus tears were acute in 16 (44.4%) patients and chronic in 20 (55.6%). ACLTR was applied together with BHMT repair in 25 patients. The hybrid technique, as the outside-in technique in addition to the all-inside technique, was applied to 12 (33.3%) patients, where there was seen to be extension to the anterior horn. The failure rate was determined as 27.8% according to the postoperative MRI evaluation and the Barrett criteria. No positive or negative statistically significant effect on healing was determined of chronic BHMT or of simultaneous application of ACLTR (p = 1.00 and 0.457, respectively). Cigarette smoking and high BMI were determined to have a statistically significant negative effect on healing (p = 0.026 and 0.007, respectively). In conclusion, it can be seen that the success of the all-inside technique for BHMT remains controversial. Due to the features of the application, it can be used in meniscus tears of the posterior horn only. In the current study, with the success rate of 72.2% of the all-inside technique in meniscus body tears, it was seen that a high success rate could not be achieved.

Objective To define patient demographics, preoperative, and intraoperative surgical variables associated with successful or failed repair of bucket-handle meniscal tears. Design All patients who underwent arthroscopic repair of a bucket-handle meniscus tear at a single institution between May 2011 and July 2016 with minimum 6-month follow-up were retrospectively identified. Patient demographic, preoperative (including imaging), and operative variables were collected and evaluated. A Kaplan-Meier curve was generated to demonstrate meniscus repair survivorship. Results In total, 75 patients (78 knees) with an average age of 26.53 ± 10.67 years met inclusion criteria. The average follow-up was 23.41 ± 16.43 months. Fifteen knees (19.2%) suffered re-tear of the repaired meniscus at an average 12.24 ± 9.50 months postoperatively. Survival analysis demonstrated 93.6% survival at 6 months, 84.6% survival at 1 year, 78.4% survival at 2 years, and 69.9% survival at 3 years. There was significant improvement from baseline to time of final follow-up in all patient-reported outcome ( P < 0.05) except Marx score ( P = 0.933) and SF-12 Mental Subscale ( P = 0.807). The absence of other knee pathology (including ligament tear, contralateral compartment meniscal tear, or cartilage lesions) noted intraoperatively was the only variable significantly associated with repair failure ( P = 0.024). Concurrent anterior cruciate ligament reconstruction (vs. no concurrent anterior cruciate ligament reconstruction) trended toward significance ( P = 0.059) as a factor associated with successful repair. Conclusions With the exception of the absence of other knee pathology (including ligament tear, contralateral compartment meniscal tear, or cartilage lesions) noted intraoperatively, no other variables were significantly associated with re-tear. The results are relatively durable with 84.6% survival at 1 year. Surgeons should attempt meniscal repair when presented with a bucket-handle tear.

Background: Clinical outcomes of surgical repairs for tears of the lateral meniscus posterior root (LMPR) in patients undergoing anterior cruciate ligament (ACL) reconstruction (ACLR) have not been comprehensively investigated. Purpose: To systematically review the clinical, radiographic, and arthroscopic results of surgical repairs for tears of the LMPR in patients undergoing ACLR. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic electronic search of the PubMed and Embase databases was performed to identify studies reporting clinical, radiographic, or arthroscopic results of surgical repairs for tears of the LMPR in patients undergoing ACLR. Each included study was abstracted regarding study characteristics, patient characteristics, surgical technique, and outcome measures. The methodological quality of the included studies was analyzed according to the Methodological Index for Non-Randomized Studies (MINORS) criteria. Results: Nine studies were included in this systematic review, representing a total of 215 knees in 215 patients. Overall, 123 side-to-side repairs and 89 pullout repairs were performed for tears of the LMPR during ACLR. After a mean follow-up of 33.9 months, significant improvements ( P < .05) were found in the mean Lysholm score (from 58.3 to 91.4) as well as the mean International Knee Documentation Committee subjective score (from 61.1 to 87.2). Weightbearing anteroposterior radiographs of 41 patients showed no significant narrowing of lateral joint space width. On magnetic resonance imaging scans, 31 patients demonstrated no significant progression of chondral lesions, and no significant decreases in meniscal extrusion on coronal planes were reported in another 76 patients. The complete/partial healing was 93.6% on second-look arthroscopy after side-to-side repairs for radial tears of the LMPR. The MINORS value showed a high risk of bias for all 9 studies. Conclusion: Patients with tears of the LMPR associated with ACL injuries achieved favorable functional scores after ACLR and LMPR repairs, and the side-to-side repair for radial tears of the LMPR succeeded in a high meniscal healing rate of >90%. However, the authors of this review were unable to definitively conclude whether LMPR repairs fully restore the hoop stress of the lateral meniscus.
