Summary:
This study aims to explore methods for enhancing pain relief following knee replacement surgery, a prevalent procedure for individuals with severe knee arthritis. Effective postoperative pain management is essential for ensuring a swift and comfortable recovery. Traditional pain management methods often involve medications that may have side effects; therefore, this study examines alternative approaches utilizing nerve blocks.

Two pain management methods are compared in this study:

Adductor Canal Block (ACB) Alone: A technique that numbs the anterior and medial regions of the knee.

Combined Adductor Canal Block and Selective Tibial Nerve Block (ACB + STNB): An innovative approach that includes an additional block to numb the posterior aspect of the knee.

The objective is to determine whether the combined approach offers superior pain relief, reduces the reliance on pain medications, and enhances overall postoperative recovery. Participants are randomly assigned to one of the two groups and receive the nerve blocks during their surgery.

This study aspires to contribute to the development of improved pain management strategies, facilitating quicker and more comfortable recovery for patients undergoing knee replacement surgery.

Primary Outcome Measures: Postoperative Pain Levels, The intensity of postoperative pain will be evaluated using the Visual Analog Scale (VAS), a widely used pain assessment tool.Measurement Details: The VAS is a 10-point scale where 0 represents "no pain" and 10 represents "the worst pain imaginable." Higher scores indicate greater pain intensity., Pain levels will be assessed at 0, 1, 2, 8, 12, and 24 hours following the completion of the surgical procedure.
Secondary Outcome Measures: Total Analgesic Consumption, Pain levels will be assessed at 0, 1, 2, 8, 12, and 24 hours following the completion of the surgical procedure., Within the first 24 hours post-surgery.|Time to First Additional Analgesic Request, Description: The time elapsed from the end of surgery to the first request for additional analgesics will be recorded.

Measurement Details: The time (in minutes) from the completion of surgery until the first patient-initiated request for additional analgesia will be measured. A longer duration indicates better initial pain control., Within the first 24 hours post-surgery|Incidence of Side Effects, Description: The incidence of side effects such as nausea, vomiting, and hypotension will be documented.

Measurement Details: The occurrence of these side effects will be recorded as a binary outcome (yes/no). Additionally, the severity of side effects will be assessed using standard clinical grading scales., Within the first 24 hours post-surgery.|Patient Satisfaction, Patient satisfaction regarding pain management and overall experience will be measured.

Measurement Details: Satisfaction will be assessed using a 5-point Likert scale, where 1 represents "very dissatisfied" and 5 represents "very satisfied." Higher scores indicate greater satisfaction., Assessed 24 hours post-surgery.
