Case Reports
Arthroscopic reduction and fixation of bony avulsion of the posterior cruciate ligament of the tibia.
Bony avulsion fractures of the posterior cruciate ligament of the tibia have commonly been treated by open reduction and internal fixation using the posterior approach. However, this approach, using the prone position, makes it difficult to investigate and treat other combined injuries of the knee joint. ⋯ The posterior sag was absent after the operation and the result was excellent. By arthroscopy, we got rigid fixation of the avulsed fragment for early rehabilitation, and detection of a concomitant injury was also possible.

Randomized Controlled Trial Multicenter Study Clinical Trial
The efficacy of intra-articular morphine for postoperative knee arthroscopy analgesia.
This article describes two prospective, randomized, double-blind clinical trials designed to investigate this. Trial 1 compared a conventional local anaesthetic agent (100 mg bupivacaine) injected intra-articularly (i.a.) with a control (normal saline) and 1 mg of i.a. morphine. No significant difference was noted in the first 4 hours between the groups with respect to visual analogue pain (VAS) scores. ⋯ At early time points (1, 2, and 4 hours) similar VAS pain scores were recorded for both 5 mg i.v. morphine and 5 mg i.a. morphine, both significantly lower than the group receiving 1 mg i.a. morphine. At 6 and 24 hours, 5 mg of i.a. morphine produced significantly lower pain scores, less analgesic requirement, and less sleep disturbance on the first postoperative night than the other groups. It can be concluded from these two studies that 5 mg i.a. was the most effective analgesic following knee arthroscopy.

Five infants with an acute hematogenous septic arthritis of the knee were treated with arthroscopically assisted drainage using the Micro-Joint Arthroscope (MJA; Linvatec, Largo, FL) combined with antibiotic therapy and early postoperative motion. The average patient age was 16 months (range, 4 to 24 months). No surgical or anesthetic complications occurred. All knees were clinically and radiologically normal at an average follow-up of 26 months.

Randomized Controlled Trial Clinical Trial
Local anesthesia for arthroscopic surgery of the ankle using pethidine or prilocaine.
Investigation of the intraoperative and postoperative pain-reducing effect of pethidine (meperidine) as compared with local anesthetics given into the ankle joint was performed, in a comparative and double-blind fashion, in 20 patients subjected to arthroscopy of the ankle, diagnostic and surgical procedures. These patients were randomly assigned to one of two groups. Group A consisted of 10 patients receiving prilocaine 5% with adrenaline and the patients of group B received pethidine 5% with adrenaline intraarticularly. ⋯ No differences were found between the two groups, except for pain at rest through the whole observation period when significant lower values for pethidine. There were no differences in use of analgesics between the two groups. The current study indicates that pethidine is a potential alternative to prilocaine in arthroscopy of the ankle.

Randomized Controlled Trial Clinical Trial
Local and intra-articular infiltration of bupivacaine before surgery: effect on postoperative pain after anterior cruciate ligament reconstruction.
In a double-blind, randomized trial, 40 patients undergoing open anterior cruciate ligament (ACL) reconstruction using a bone-patellar tendon-bone autograft were randomly allocated to two groups: group A (n = 20) received an intra-articular instillation of 20 mL bupivacaine (0.25%) and a local infiltration of 20 mL bupivacaine (0.5%) 15 minutes before surgery. Group B (n = 20) received an injection of saline solution in the same manner. Patient-controlled on-demand analgesia (PCA) with intravenous piritramid was used for postoperative pain control. ⋯ At all other times, no significant differences were found. The overall supplemental opioid requirements were not different between the study groups (63.9 v 62.6 mg piritramid/72 hours). A long-lasting, clinically relevant, pain-reducing effect with infiltration of bupivacaine before surgery could not be shown with this study.
