Background: Arthroscopic meniscal surgery is a common orthopaedic procedure in middle-aged patients, but the efficacy of this procedure has been questioned. In this study, we followed up the only randomized controlled trial that has shown a 1-year benefit from knee arthroscopic surgery with an exercise program compared with an exercise program alone. Purpose: To (1) evaluate whether knee arthroscopic surgery combined with an exercise program provided an additional 5-year benefit compared with an exercise program alone in middle-aged patients with meniscal symptoms, (2) determine whether baseline mechanical symptoms affected the outcome, and (3) compare radiographic changes between treatment groups. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Of 179 eligible patients aged 45 to 64 years, 150 were randomized to either a 3-month exercise program (nonsurgery group) or to the same exercise program plus knee arthroscopic surgery (surgery group) within 4 weeks. Radiographs were assessed, according to the Kellgren-Lawrence grade, at baseline and at the 5-year follow-up. The primary outcome was the change in Knee injury and Osteoarthritis Outcome Score (KOOS)–Pain (KOOSPAIN) subscore from baseline to the 5-year follow-up. We performed an as-treated analysis. Results: A total of 102 patients completed the 5-year questionnaire. At the 5-year follow-up, both groups had significant improvement in KOOSPAIN subscores, although there was no significant change from the 3-year scores. There was no between-group difference in the change in the KOOSPAIN subscore from baseline to 5 years (3.2 points [95% CI, –6.1 to 12.4]; adjusted P = .403). In the surgery group, improvement was greater in patients without mechanical symptoms than in those with mechanical symptoms (mean difference, 18.4 points [95% CI, 8.7 to 28.1]; P < .001). Radiographic deterioration occurred in 60% of patients in the surgery group and 37% of those in the nonsurgery group ( P = .060). Conclusion: Knee arthroscopic surgery combined with an exercise program provided no additional long-term benefit after 5 years compared with the exercise program alone in middle-aged patients with meniscal symptoms. Surgical outcomes were better in patients without mechanical symptoms than in patients with mechanical symptoms during the preoperative period. Radiographic changes did not differ between treatment groups. Registration: NCT01288768 ( ClinicalTrials.gov identifier).

“…At 1-year follow-up of patients previously diagnosed with concurrent osteoarthritis and meniscus damage, 80.8% of knees that underwent partial meniscectomy demonstrated cartilage loss in the interval period compared with 37.4% of knees that had no meniscus surgery. 6 This disparity may be attributed to the increased knee joint load following a partial meniscectomy, as noted by Thorlund et al 8 Compared with partial meniscectomies, meniscus repairs focus on preserving as much meniscal tissue as possible to retain its biomechanical properties. Today, the inside-out repair technique is considered the gold standard for treatment due to its good clinical outcomes in addition to its versatility and use of smaller diameter needles.…”

“…6,7 Although meniscectomies provide symptomatic relief, the loss of meniscus tissue increases knee joint load and significantly increases the longterm risk for osteoarthritis. 7,8 Thus, if possible, a meniscus repair should be performed to retain biomechanical function.…”

Meniscus tears are among the most common knee injuries in the general population and often are treated arthroscopically with a meniscus repair. Of the various meniscus repair techniques available, the inside-out meniscus tear is considered the gold standard due to its versatility and good clinical outcomes. The purpose of this Technical Note and accompanying video is to describe an inside-out bucket-handle meniscus repair using a single handed, self-advancing meniscus repair device with an interchangeable zone-specific multicannula system to decrease the technical difficulty and operative time of the repair.

“…[6,14] . Increasingly more studies have suggested [15][16][17] that meniscus injury or defect will lead to an increase in the incidence of osteoarthritis, and thus meniscal repair has received increasingly more attention. Among the repair methods of meniscus injury [18] , meniscal suture repair is the mainstream repair method at present, and includes three types of repair: outside-in repair, inside-out repair and all-inside repair.…”

Background: In consideration of meniscal repair has received increasingly more attention, but for inexperienced doctors, various technical errors may occur when meniscal suture repair is performed, particularly during all-inside meniscal suture repairing. When the errors is happened intraoperatively, how to minimize the loss under the effectiveness of treatment is a topic worth studying. Methods: From May 2014 to May 2017, 28 cases diagnosed with injures of meniscus and anterior cruciate ligaments were enrolled in the study as observation group. All cases underwent anterior cruciate ligament (ACL) reconstruction concurrently. All meniscus injuries were repaired with an allinside meniscal repair technique, and 1-3 needles of unilateral suture anchor pulling out occurred intraoperatively. The method of modified cross-suture was used to remedy the error of anchor pulling out and to eventually complete the effective repair. During postoperative follow-up, the range of motion, Lachman test and pivot shift test were confirmed by physical examination. The clinical healing of meniscus was evaluated according to the Barrett standard. Meniscus healing status was also confirmed with magnetic resonance imaging (MRI). The function of the knee joint was evaluated with the IKDC, Lysholm and Tegner scores. Results: 25 cases of observation group and 28 cases of control group received complete follow-up with an average follow-up of 18.4±5.2 months. All operations were finished by the same surgeon. Atthe follow-up one year after operation, the average knee ROM of two groups were 125.2±4.3 degrees and 124.7±3.8 degrees, the clinical healing rate of the meniscus of two groups were 92.0% (23/25) and 92.9% (26/28), the MRI healing rate of the menniscus of two groups were 72.0% (18/25) and 71.4% (20/28), the IKDC, Lysholm and Tegner scores of two groups were 90.52±2.8, 89.17±3.1, 6.81±1.7 and 91.42±1.9, 90.32±3.4, 7.02±1.4, the differences were not statistically significant (P>0.05).Conclusions: The method of modified cross-suture is effective for arthroscopic remediation for unilateral suture anchor pulling out of an all-inside meniscal repair system.
