This study sought to compare the effects of saline with mor-phine, bupivacaine with or without epinephrine, administrated intraarticularly upon pos-toperative pan following arthroscopic knee surgery under general anesthesia.
In a double-blined, randommized manner, 40 patients received one of saline(20ml, n=10), morphine(1mg in 20ml NaCl, n=10), bupivacaine(0.25%, 20ml, n=10), bu-pivacaine with epinephrine(0.25%, 20ml, 200ug of epinephrine, n=10) intaarticularly at the completion of surgery. The pain scores by VAS were determined after 1,2,3,4 and 24 hours after intraarticular administration.
There were no significant statistical differences between four groups in the pain score. The maximal pain scores were 37.5 in control group, 48.0 in morphine group, 33.6 in bupivacaine group postoperative 1 hour and 32.9 in bupivacaine with epinephrine group pos-toperative 2 hours. The pain scores were decreased as the time went by and were minimin as 21.4 in control group, 17.6 in morphine group, 11.2 in bupivacaine group and 12.3 in bu-pivacaine with epinephrine group 24 hour postoperatively.
Though there were no significant statistical significances with those doses, there were tendencies that the bupivacaine group with or without epinephrine had the postoperative analgesic effect rather than control group, and morphine group had a slow onset of analgesic ef-fect. So, we should study to decide the dose or volume of the drugs and appropriate time to evaluate for the anagesic effects after knee arthroscopy further.
Arthroscopy of the knee joint is an essential diagnostic procedure of the knee joint lesions because of its high diagnostic accuracy, simple procedure, high safty and low morbidity. We applied arthroscopy in the diagnosis of 62 patients with pain, swelling, limitation of motion and giving way of the knee joint from Jan. 1987 to Dec. 1991 at Ewha Womans University Hospital. Only 49 patients of these were followed over 6 months and we analysed and compared with clinical diagnosis and rthroscopic findings.
The results were follows :
1) Patients with knee joint lesions were most common in 3rd and 4th decades.
2) Patients with traumatic history were 57.1% (28 patients).
3) Most common lesions were meniscal lesion and most commonly used method of treatment after arthroscopy was meniscectomy.
4) Three patients with internal derangement of knee were diagnosed meniscal injury after arthroscopy.
