Meniscal Repair Outcomes at Greater Than 5 Years: A Systematic Review and Meta-Analysis.

BACKGROUND: The utilization of meniscal repair techniques continues to evolve in an effort to maximize the rate of healing. Meniscal repair outcomes at a minimum of 5 years postoperatively appear to better represent the true failure rates. Thus, a systematic review and meta-analysis of the current literature was conducted to assess the rate of failure at a minimum of 5 years after meniscal repair. METHODS: We performed a systematic review of studies reporting the outcomes of meniscal repair at a minimum of 5 years postoperatively. A standardized search and review strategy was utilized. Failure was defined as recurrent clinical symptoms or a meniscal reintervention to repair or resect the meniscus in any capacity, as defined by the study. When reported, outcomes were assessed relative to anterior cruciate ligament (ACL) status, sex, age, and postoperative rehabilitation protocol. Meta-analyses were performed with a random-effects model. RESULTS: A total of 27 studies of 1,612 patients and 1,630 meniscal repairs were included in this review and meta-analysis. The pooled overall failure rate was 22.6%, while the failure rate of modern repairs (excluding early-generation all-inside devices) was 19.5%. Medial repairs were significantly more likely to fail compared with lateral repairs (23.9% versus 12.6%, p = 0.04). Failure rates were similar for inside-out (14.2%) and modern all-inside repairs (15.8%). Early-generation all-inside devices had a significantly higher failure rate (30.2%) compared with modern all-inside devices (15.8%, p = 0.01). There was no significant difference in meniscal failure rate between repairs with concomitant ACL reconstruction (21.2%) and repairs in ACL-intact knees (23.3%, p = 0.54). CONCLUSIONS: Modern meniscal repair had an overall failure rate of 19.5% at a minimum of 5 years postoperatively. Modern all-inside techniques appear to have improved the success rate of meniscal repair compared with use of early-generation all-inside devices. Lateral repairs were significantly more likely to be successful compared with medial repairs, while no difference was seen between patients undergoing meniscal repair with and without concomitant ACL reconstruction.

Editorial Commentary: Knee Meniscal Allograft Transplantation Results in Significantly Improved Outcomes in the Majority Patients, but There Is Wide Variability in the Rate at Which Athletes Return to Sports.

Meniscal allograft transplantation (MAT) is the reconstructive procedure of choice following a total or near-total meniscectomy for the symptomatic patient with a stable, well-aligned knee prior to the onset of degenerative arthritis. Historically, the goals were to eliminate symptoms with activities of daily living and improve longevity of the articular cartilage. However, athletically active individuals are rarely satisfied unless they return to their prior level of function, which is dependent on patient-specific, knee-specific, and sports-specific factors. Despite the fact that subjective patient-reported outcomes are significantly improved in the majority of MAT patients, there is wide variability in the rate at which athletic patients are able to return to sports, when they return, and their ultimate level of performance. We advise active individuals who undergo a MAT to pursue "low-impact" activities based on 10-year survivorship of 70% to 80%. Risk of a recurrent meniscal tear is the most common complication, and the ability of MAT to prevent osteoarthritis is unproven.

What They Want - Caregiver and Patient Immobilization Preferences for Pediatric Buckle Fractures of the Wrist.

Background: Recent literature supports minimalist approaches such as splinting for pediatric buckle fractures of the wrist. Uptake of this practice, however, has lagged behind the evidence. Barriers to implementation of this strategy necessitate further investigation, and caregiver and patient preferences represent an obstacle that has not been previously evaluated. This study sought to examine caregiver and patient treatment preferences and factors influencing care decisions for buckle fractures of the wrist. We hypothesized that the majority of caregivers and patients prefer cast immobilization for buckle fractures of the wrist. Methods: A 22-item caregiver survey was created to assess demographics, treatment preferences and influential factors. The survey was completed by a convenience sample of caregivers presenting with patients of any diagnosis to our pediatric orthopaedic clinic. Results: 297 surveys were collected predominantly from mothers (81.2%) caring for 2.4 (SD 1.3) children. Forty-one percent had previously cared for a child with a fracture. Caregivers accompanied patients who were 9.0+/-5.0-years-old, 34% of whom were actively being treated for an orthopaedic injury. Caregiver immobilization preferences for buckle fractures of the wrist were: no preference (43.1%), cast (32.3%) and splint (24.6%). The doctor's recommendation was the most influential factor on this decision while the child's gender was the least of the factors assessed. Those who rated treatment durability and child's activity level higher were associated with a preference for casting, while those who rated comfort higher were associated with a preference for splinting. Discussion: This study is the first to characterize caregiver preferences regarding immobilization devices in the realm of buckle fractures of the wrist. Findings identified that preferences are mixed, with the interest in casting being less than anticipated. Factors influencing caregiver preference include the doctor's recommendation, durability, the patient's activity level, and comfort. Findings can help guide treatment discussions for providers seeking to implement splint-based immobilization strategies.Level of Evidence: III.
