Background: Anterior cruciate ligament (ACL) reconstruction requires an extended period of postoperative rehabilitation. Psychological factors can affect recovery after surgery. Study of psychological factors is still limited to self-motivation, fear and pain. Study of personality traits associated with early rehabilitation outcome after ACL reconstruction is scarce., Objective: We aimed to explore the effect of personality traits on early rehabilitation after ACL reconstruction and provide a reference for clinicians in designing a personalized rehabilitation plan., Methods: This prospective analysis investigated 155 patients at 3 and 6 months after ACL reconstruction. Follow-up involved administration of a general data questionnaire, the Chinese Big Five Personality Inventory Brief Version, the Tegner activity score, the International Knee Documentation Committee Subjective Knee Score, the Knee injury and Osteoarthritis Outcome Score, the Lysholm Score and a balance test., Results: Among the 155 patients included (124 males), Neuroticism was negatively correlated with subjective knee scores at 3 and 6 months after surgery (p<0.001). The odds of a poor balance test result was increased for each 1-point increase in Neuroticism score (odds ratio [OR] 1.74, 95% confidence interval [CI] 1.28-2.36, p<0.001). We found a positive correlation between Conscientiousness score and subjective knee scores at 3 and 6 months after surgery (p<0.001). For every 1-point increase in Conscientiousness score, the odds of a poor balance test result were decreased (OR 0.29, 95% CI 0.16-0.54, p<0.001). Agreeableness and Openness to experience scores were positively correlated with subjective knee scores at 3 and 6 months after surgery (p<0.001). We found no correlation between Extraversion and subjective knee scores at 3 and 6 months after surgery (p>0.05) but a positive correlation with the Tegner activity score at 3 and 6 months after surgery (p<0.05)., Conclusion: We found a significant correlation between the Big Five personality dimensions and the early rehabilitation effect after ACL reconstruction, which can provide a reference for clinicians in designing a personalized rehabilitation plan., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2021 Elsevier Masson SAS.

Background: Several suture repair techniques have been reported for radial tear close to the posterior lateral meniscal root (type II PLMRT). However, no study has evaluated the clinical results after repair using the FasT-Fix system. This paper describes a novel H-plasty surgical repair technique and reports its clinical results., Methods: From January 2015 to January 2017, 47 patients underwent repair of type II PLMRT with concomitant anterior cruciate ligament reconstruction and were included in this study. Assessments performed preoperatively and at final follow-up included the Lysholm score, subjective International Knee Documentation Committee (IKDC) score, and knee stability assessments (pivot-shift test, Lachman test, KNEELAX arthrometer side-to-side difference). Magnetic resonance imaging was used to compare the lateral meniscal extrusion pre- versus postoperatively. Second-look arthroscopy was performed to evaluate the meniscal healing in 38 cases., Results: Forty-seven patients were followed up for an average of 30.7 months (range 18-46 months). No patients experienced meniscal mechanical symptoms. At final follow-up, there were significant improvements in the Lysholm score, IKDC score, knee stability assessments, and lateral meniscal extrusion compared with the preoperative values. In the 38 of 47 patients that underwent second-look arthroscopy after an average of 17.5 months (range 14-19 months), all repairs (100%) were completely healed., Conclusions: The novel H-plasty repair using the FasT-Fix system was an effective surgical treatment for type II PLMRT. Considering the satisfactory clinical results and the convenience of the surgery, H-plasty repair is recommended to be used preferentially., Competing Interests: Declaration of competing interest The authors declare there is no conflict of interest., (Copyright © 2020 Elsevier B.V.
