About this trial

This is an interventional treatment trial for Pain, Postoperative focused on measuring anterior cruciate ligament, arthroscopy, knee, post-surgical pain

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients who had undergone an uncomplicated ACL reconstruction procedure and were in satisfactory health were included in the study
  • In addition, they needed to have a baseline pain intensity of ≥ 50 mm on the VAS and "moderate to severe" pain on the categorical scale within 8 hours of the completion of the surgical procedure to be included

Exclusion Criteria:

  • Patient was scheduled to undergo any other surgical procedure, along with the orthopedic procedure, that was expected to produce a greater degree of surgical trauma than the orthopedic procedure alone
  • The patient was undergoing bilateral knee arthroscopy
  • The patient used conventional NSAIDs, COX-2 inhibitors, or Tramadol during the 6 hours preceding surgery, during surgery or subsequent to the end of surgery, until randomization
  • The patient received oxaprozin or piroxicam within one week prior to randomization
  • The patient was required to take muscle relaxants, tricyclic antidepressants, tranquilizers, sedatives, hypnotics and neuroleptics, in the post operative period after the patient was randomized into the study
  • The patient had been treated with patient controlled analgesia subsequent to the end of the surgical procedure
