Abstract
Purpose: To investigate kneeling tolerance in patients undergoing hamstring (HT) versus quadriceps (QT) anterior cruciate ligament reconstruction (ACLR) and investigate correlation with patient-reported outcome measures (PROMs).
Methods: After recruitment and randomisation, 112 patients (HT = 55; QT = 57) underwent ACLR. Patients were assessed at 6, 12 and 24 months using the Kneeling Tolerance Test, which evaluates patient-reported pain in a position of both 90 (KT90) and 110 (KT110) degrees of knee flexion. PROMs collected included the International Knee Documentation Committee (IKDC) questionnaire and the ACL Return to Sport after Injury (ACL-RSI) questionnaire.
Results: Kneeling tolerance at KT90 and KT110 improved (p < 0.05) for both graft types across all time points. There was no difference in KT90 scores between groups at 6 or 12 months. At 24 months, kneeling tolerance was superior in the QT group (mean HT 93 ± 9 vs. QT 98 ± 5; p = 0.003). For KT110 scores, a statistically significant difference was noted at 6 (mean HT 80 ± 25 vs. QT 89 ± 12; p = 0.027), 12 (mean HT 90 ± 13 vs. QT 95 ± 10; p = 0.040) and 24 months (mean HT 92 ± 10 vs. QT 97 ± 5; p = 0.003). The ACL-RSI was significantly correlated with KT90 and KT110 at 24 months (r = 0.40, p < 0.001; r = 0.40, p < 0.001). Other PROMs demonstrated significant weak-to-moderate correlations with kneeling tolerance.
Conclusion: Patients undergoing ACLR with a QT versus HT autograft report superior kneeling tolerance up to 2 years postsurgery, more prominent in deeper (110°) knee flexion. A strong correlation with ACL-RSI was demonstrated at 2 years.

期刊介绍：
Few other areas of orthopedic surgery and traumatology have undergone such a dramatic evolution in the last 10 years as knee surgery, arthroscopy and sports traumatology. Ranked among the top 33% of journals in both Orthopedics and Sports Sciences, the goal of this European journal is to publish papers about innovative knee surgery, sports trauma surgery and arthroscopy. Each issue features a series of peer-reviewed articles that deal with diagnosis and management and with basic research. Each issue also contains at least one review article about an important clinical problem. Case presentations or short notes about technical innovations are also accepted for publication.
The articles cover all aspects of knee surgery and all types of sports trauma; in addition, epidemiology, diagnosis, treatment and prevention, and all types of arthroscopy (not only the knee but also the shoulder, elbow, wrist, hip, ankle, etc.) are addressed. Articles on new diagnostic techniques such as MRI and ultrasound and high-quality articles about the biomechanics of joints, muscles and tendons are included. Although this is largely a clinical journal, it is also open to basic research with clinical relevance.
Because the journal is supported by a distinguished European Editorial Board, assisted by an international Advisory Board, you can be assured that the journal maintains the highest standards.
Official Clinical Journal of the European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA).
