    No association detected between posterior tibial slope, static anterior tibial translation and medial meniscus repair failure after anterior cruciate ligament reconstruction
    (Wiley, 2026) Mazy, David; Cance, Nicolas; Angelelli, Lucia; Pineda, Tomás; Dan, Michael James; Dejour, David Henri
    Purpose: This study aimed to evaluate the influence of the posterior tibial slope (PTS) and static anterior tibial translation (SATT) on the success of medial meniscus (MM) repair performed concomitantly with anterior cruciate ligament reconstruction (ACLR). Methods: In this retrospective study, all patients who underwent primary ACLR using hamstring autograft combined with isolated MM repair between January 2014 and December 2017, and a minimum follow‐up of 6 years, were included. Patients who had undergone meniscectomy or lateral meniscus repair were excluded. Demographic data, PTS, SATT, dynamic anterior tibial translation (DATT), the need for reoperation (at the same location) for MM repair failure (MMRF), and time to failure were recorded. Comparative analyses were performed using thresholds of 12° for PTS and 5 mm for SATT. Univariate logistic regression analyses were used to identify independent risk factors for MMRF. Results: Among the 148 patients included, 14 (9.4%) experienced a MMRF at a mean of 24 ± 16 months post‐operatively (range 7–60 months). Twenty‐ eight percent of patients had undergone concomitant lateral extra‐articular tenodesis (LET). There were no significant differences between the MMRF and non‐failure groups in terms of age, sex, presence of LET, PTS, SATT or DATT. Patients with PTS ≥ 12° (odds ratio, 2.9; 95% confidence interval, 0.8–11.6; p = 0.11) or SATT ≥ 5 mm did not demonstrate a higher rate of MMRF. No variable from the univariate analysis met the criteria for inclusion in the multivariate analysis. Limited number of MMRF events increase potential risk of type II error. Conclusion: No statistically significant association was detected between PTS, SATT, DATT, age or the presence of LET and MMRF after hamstring ACLR. However, larger studies are needed, particularly in high‐slope subgroups. Increased PTS or SATT alone should not discourage MM repair in the setting of ACLRMedial meniscus

    Posterior tibial slope and static anterior tibial translation are not associated with increased cyclops syndrome after anterior cruciate ligament reconstruction
    (Wiley, 2026) Mazy, David; Cance, Nicolas; Angelelli, Lucia; Pineda, Tomás; Pintore, Andrea; Dejour, David Henri
    Purpose: Posterior tibial slope (PTS) and static anterior tibial translation (SATT) are established risk factors for anterior cruciate ligament (ACL) graft rupture and may also be associated with cyclops syndrome. This study aimed to assess whether these anatomical parameters influence the prevalence of cyclops syndrome after ACL reconstruction (ACLR). The hypothesis of the present study was that increased PTS and SATT would facilitate the development of cyclops syndrome. Methods: Patients aged ≥14 years with a minimum follow-up of 6 years who underwent primary ACLR with hamstring autograft between January 2015 and December 2017 were included. Demographic data, PTS, SATT, concomitant lateral extra-articular tenodesis (LET) and reoperation for cyclops syndrome were recorded. Time from index surgery to arthrolysis was documented, with a minimum follow-up of 6 years. Subgroup analysis regarding PTS, SATT and gender was performed. Univariate and multivariate logistic regression analyses were conducted to identify independent risk factors. Results: Of 530 patients included for analysis, 18 (3.4%) developed cyclops syndrome at a mean of 14 ± 9 months postoperatively (range, 6–33 months). Patients with a PTS ≥ 12° had a 4.3% rate of cyclops syndrome compared with 3.2% in those with a PTS < 12° (p = 0.536). Patients with a SATT ≥ 5 mm had a 5.6% rate compared with 2.7% for SATT < 5 mm (p = 0.154). Female patients presented a statistically significant higher prevalence (5.9%) compared with males (1.8%, p = 0.024). Concomitant LET did not demonstrate a protective effect (p = 0.807). Female sex was the only independent predictor of cyclops syndrome (OR, 3.3; 95% CI, 1.2–9.1; p = 0.018). Conclusion: This study found no evidence that increased PTS or SATT predisposes to cyclops syndrome after ACLR with hamstring autograft. These preoperative parameters should not alert clinicians to an increased risk of postoperative cyclops syndrome.

    Preoperative dynamic anterior tibial translation is not predictive of graft rupture after anterior cruciate ligament reconstruction
    (Wiley, 2026) Pineda, Tomás; Mazy, David; Cance, Nicolas; Lucia Angelelli; Pineda, Tomás; Dan, Michel James; Dejour, David Henri
    Purpose: This study aimed to determine whether higher preoperative dynamic anterior tibial translation (DATT) using laximetry is a risk factor for graft rupture after anterior cruciate ligament reconstruction (ACLR). Methods: This retrospective study included all patients who underwent primary ACLR with hamstring autograft between January 2014 and December 2017. Demographic data, absolute DATT on the injured side and ΔDATT (side‐to‐side difference), posterior tibial slope (PTS), static anterior tibial translation (SATT), concomitant lateral extra‐articular tenodesis (LET) and meniscal tears were collected. Subgroup analysis was performed using a ΔDATT threshold of 6 mm. Univariate and multivariable logistic regression analyses were conducted to identify independent risk factors for ACL graft rupture. Results: Among the 680 patients included with a minimum follow‐up of 6 years, 41 (6%) experienced graft rupture at a mean of 45 ± 30 months postoperatively. The median DATT on the injured side was 9 mm [interquartile range, IQR, 5], and the median ΔDATT was 6 mm [IQR, 4]. Graft rupture occurred in 5.8% for patients with ΔDATT < 6 mm and in 6.3% for patients with ΔDATT ≥ 6 mm (p = 0.787). Patients with ΔDATT ≥ 6 mm demonstrated a higher prevalence of medial meniscal tears (31% vs. 24%, p = 0.026). Independent risk factors for graft rupture included PTS ≥ 12° (odds ratio [OR] 3.1; 95% confidence interval [CI], 1.6–6.3; p < 0.001) and SATT ≥ 5 mm (OR 2.6; 95% CI, 1.2–5.5; p = 0.027), whereas neither ΔDATT nor absolute DATT was significantly associated with graft rupture. Conclusion: Preoperative DATT is not predictive of graft rupture following ACLR using hamstring autograft. PTS and SATT remain stronger predictors and should be prioritised for preoperative risk stratification.
