Undergoing open or arthroscopic Achilles tendon surgery;
Conscious and able to cooperate in surgery and postoperative pain assessment;
Complete and accessible case data related to surgery, anesthesia, and postoperative pain assessment;
Completion of at least 24 hours of standardized pain monitoring and clinical follow-up after surgery

Exclusion Criteria:

Missing or incomplete key clinical data such as pain assessment, surgery and anesthesia;
Failure to complete 24-hour standardized pain monitoring after surgery; Perioperative unplanned secondary surgery or transfer to the intensive care unit (ICU);

Hva måler studien?

Primære resultatmål

Resultatmål	Tiltaksbeskrivelse	Tidsramme
Incidence of Moderate-to-Severe Acute Postoperative Pain Tidsramme: Within 24 hours after surgery	Defined as a pain score ≥ 4 on the Numeric Rating Scale (NRS) or the need for rescue analgesia within the first 24 hours after Achilles tendon surgery. The NRS is an 11-point scale ranging from 0 (no pain) to 10 (worst imaginable pain), where higher scores indicate greater pain severity (worse outcome).	Within 24 hours after surgery

Sekundære resultatmål

Resultatmål	Tiltaksbeskrivelse	Tidsramme
Rescue Analgesia Requirement Tidsramme: Within 24 hours after surgery	Proportion of patients requiring rescue analgesic medications within 24 hours after surgery.	Within 24 hours after surgery
Incidence of Postoperative Nausea and Vomiting (PONV) Tidsramme: Within 24 hours after surgery	Proportion of patients experiencing nausea or vomiting requiring antiemetic treatment within 24 hours after surgery.	Within 24 hours after surgery
Postoperative Length of Hospital Stay Tidsramme: From surgery to hospital discharge (up to 7 days)	Number of days from surgery to hospital discharge.	From surgery to hospital discharge (up to 7 days)
Highest Postoperative Pain Score Tidsramme: Within 24 hours after surgery	The maximum pain score recorded within 24 hours after Achilles tendon surgery, measured using the Numeric Rating Scale (NRS). The NRS is an 11-point scale ranging from 0 (no pain) to 10 (worst imaginable pain), where higher scores indicate greater pain severity (worse outcome).	Within 24 hours after surgery
