- Purpose: To compare knee anatomical parameters of patients with failed anterior cruciate ligament reconstruction (ACL-R) with those of a control group of sex-matched patients with successful ACL-R. Methods: Forty-three patients (34 male, 9 female) who experienced graft failure after ACL-R were enrolled in the failed group. These patients were matched to a control group of 43 patients who underwent primary ACL-R with a minimum follow-up of 24 months. On magnetic resonance imaging, the following parameters were evaluated: transepicondylar distance, lateral and medial femoral condyle widths, tibial plateau width, notch width index, and the ratio of width and height of the femoral notch, ratio between the height and depth of the lateral and medial femoral condyle, lateral and medial posterior tibial slopes, and anterior subluxation of the lateral and medial tibial plateau. Multivariate regression with backward elimination, including only the previously identified significant variables, defined the independent predictors for revision surgery. Results: The anatomical variables that were significantly different between the 2 study groups were lateral and medial posterior tibial slopes, anterior subluxation of the lateral and medial tibial plateau, medial tibial plateau width, lateral tibial plateau width, medial femoral condyle width, and transepicondylar distance; however, the multivariate regression analysis identified the lateral posterior tibial slope (LTPs), the anterior subluxation of the medial tibial plateau, and the medial femoral condyle width as significant independent predictors (P < .05). The LPTs had the highest coefficient and the highest sensitivity (88%) and specificity (84%) to identify failures when considering the optimal cutoff value of 7.4 degrees. Conclusions: Several anatomical parameters have been identified that differ significantly between patients with failed ACL-R and those without a documented failure. The most accurate predictor of ACL failure was an LTPs >7.4 degrees, with a sensitivity of 88% and specificity of 84%. Surgeons should consider measuring LTPs during preoperative assessment of ACL-injured patients, and patients with values >7.4 degrees should be considered at high risk of ACL-R failure.

- Context: Meniscal injuries are common among both sport-and non-sport-related injuries, with over 1.7 million meniscal surgeries performed worldwide every year. As meniscal surgeries become more common, so does meniscal allograft transplantation (MAT). However, little is known about the outcomes of MAT in active patients who desire to go back to preinjury activities. Objective: The purpose of this systematic review and meta-analysis was to evaluate return to sport, clinical outcome, and complications after MAT in sport-active patients. Data Sources: A systematic search of MEDLINE, EMBASE, and CINAHL electronic databases was performed on February 25, 2018. Study Selection: Studies of level 1 through 4 evidence looking at MAT in physically active patients with reported return to activity outcomes and at least 2-year follow-up were included. Data Extraction: Details of sport-related outcomes and reoperations were extracted and pooled in a meta-analysis. Results: Nine studies were included in this systematic review. A majority (77%) of athletes and physically active patients were able to return to sport after MAT; two-thirds were able to perform at preinjury levels. Graft-related reoperations were reported in 13% of patients, while the joint replacement rate with partial or total knee prosthesis was 1.2%. Conclusion: Physical activity after MAT appears possible, especially for low-impact sports. However, because of the limited number of studies, their low quality, and the short-term follow-up, the participation recommendation for high-impact and strenuous activities should be considered with caution until high-quality evidence of long-term safety becomes available.
