Brief summary
In this study, the minimum effective concentration required for supra-inguinal fascia iliaca block applied in patients undergoing arthroscopic knee surgery is aimed. The same volume will be used in all of the block applications in the study, and the local anesthetic concentration used will be determined by increasing or decreasing according to the success of the previous block. The primary goal of the study is block success.
Detailed description
For patients included in the study, 40 mL of local anesthetic will be used for SIFIB. The local anesthetic concentration will be randomized using the biased-coin design up-down sequential method, as suggested by Durham et al. and described by Dixon. The primer outcome of this study is block success. Also, the incidence of motor block formation in the quadriceps muscle (to be defined as paresis or paralysis in knee extension), the amount of tramadol needed in 24 hours, opioid-related side effects (postoperative nausea/vomiting, itching), length of hospital stay and complications that may develop related to the block will be recorded.

Masking description
All blocks will be performed by the same experienced anesthetist to ensure block quality and homogeneity. The anesthetist applying the block will not take part in the patient follow-up, the independent assistant following the patient will be blinded to the study.
Intervention model description
As suggested by Durham et al and described by Dixon, study randomization will be performed using the biased-coin design up-down sequential method.
