Aktiv komparator: Group 1: ACB at the proximal vasto-adductor membrane level (20 mL 0.25% bupivacaine)
Group 1: Patients receiving ultrasound-guided adductor canal block with 20 mL of 0.25% bupivacaine at the level where the vasto-adductor membrane is first visualized.

In this study, patients were evaluated using two distinct approaches based on the evolution of anatomical definitions in recent literature: the proximal application, traditionally referred to as the adductor canal block but now more accurately defined as the 'Femoral Triangle Block' in current publications,

Aktiv komparator: Group 2: Level of the end of the adductor longus
Group 2: Patients receiving ultrasound-guided adductor canal block with 20 mL of 0.25% bupivacaine at the level where the adductor longus muscle ends.

In this study, patients were evaluated using two distinct approaches based on the evolution of anatomical definitions in recent literature: the proximal application, traditionally referred to as the adductor canal block but now more accurately defined as the true 'Distal Adductor Canal Block' performed in accordance with contemporary anatomical criteria."

Proximal spread of local anesthetic
Tidsramme: The first postoperative hour
|
The primary objective of this study is to compare the proximal spread of local anesthetic following ultrasound-guided adductor canal block performed at two distinct injection levels.
In the first group, the injection will be administered at the level where the vastoadductor membrane is first visualized ultrasonographically in the proximal region.
In the second group, the injection will be performed at the level where the adductor magnus and sartorius muscles first intersect.In both patient groups, the area of local anesthetic spread at the apex of the iliopectineal fossa will be measured in $cm^2$ using ultrasonography.
Additionally, the distance between the needle insertion point (injection level) and the apex of the iliopectineal fossa, as well as the distance from the needle insertion point to the most proximal point where the local anesthetic is ultrasonographically visualized, will be recorded in cm.

Pain Scores (Numeric Rating Scale)
Tidsramme: post-op hours 6 and 24
|
Evaluation of NRS(Numeric Rating Scale) scores at the 6th and 24th postoperative hours.The Numerical Rating Scale (NRS) is a common subjective clinical tool that requires patients to quantify their pain intensity on a scale ranging from 0 to 10

post-op hours 6 and 24

Assessment of Motor Block
Tidsramme: Postoperative 24th hours
|
Motor block and falls were evaluated at the 24th hour.Ambulation was assessed within the first 24 hours postoperatively.
Successful ambulation was defined as the ability to walk without falling; patients who failed to ambulate or suffered a fall during the attempt were categorized as 'treatment failure'.
