Randomized Controlled Trial Comparative Study Clinical Trial
Analgesic effect of intraarticular morphine, bupivacaine, and morphine/bupivacaine after arthroscopic knee surgery.
In a double-blind randomized fashion, 38 patients were divided into four groups according to the intraarticular injection received after arthroscopic surgery. Patients in group I (n = 7) received saline, group II (n = 10) morphine, group III bupivacaine, and group IV (n = 11) morphine and bupivacaine. Before surgery and at 0.5, 1, 1.5, 2, 6, and 24 h postoperatively, pain levels were recorded. ⋯ Although there was a statistically significant difference in pain scores between the saline group and the other three groups during the early postoperative period, there was no significant difference in pain scores between the morphine, bupivacaine, and morphine/bupivacaine groups. We conclude that postoperative, intraarticular injection of analgesics is beneficial in reducing pain levels. The combination of morphine/bupivacaine appears to be the most beneficial analgesic due to its low supplemental analgesic requirements postoperatively.

Recent reports indicate that combined anterior cruciate ligament/medial collateral ligament (ACL/MCL) knee injuries are usually associated with a lateral meniscus tear. In our center, snow skiing is the athletic activity most frequently associated with this double-ligament injury complex. A sports-specific analysis was undertaken to evaluate the hypothesis that the snow skiing ligament injury is different from similar injuries caused by other athletic activities. ⋯ Skiers were older (average age 35 years) than the nonskiers (average age 28 years). The right knee was injured almost twice as frequently as the left. These data suggest that the double (ACL/MCL) ligament injury in skiers might be distinctly different from that in nonskiers.

An unexpected degree of joint contamination was detected during arthroscopic debridement of three intraarticular, low-velocity gunshot wounds to the knee. When bullet wounds traverse a joint, it is recommended that clothing be inspected for fabric defects and that arthroscopy be considered for the surgical debridement.

Randomized Controlled Trial Comparative Study Clinical Trial
Pain relief after arthroscopic surgery of the knee: a prospective, randomized, and blinded assessment of bupivacaine and bupivacaine with adrenaline.
A prospective, randomized, and double-blind study was conducted to compare the influence on postoperative pain of equal volumes of saline, bupivacaine, or bupivacaine with adrenaline, injected both intraarticularly and into the wound puncture site, for 118 day case patients undergoing elective knee arthroscopy. Marginal analyses of postoperative visual analogue pain scores and postoperative fentanyl doses showed that the group given bupivacaine with adrenaline had less postoperative pain when compared with the saline group. However, when multifactor analyses were performed, preoperative visual analogue pain scores, operation type and length, and the sex of the patient were all shown to be significant predictors of postoperative pain, but the use of bupivacaine was not. We conclude that the observed differences in postoperative pain were due to differences between the groups in these predictive factors, especially preoperative pain scores, and that the use of bupivacaine was less important and not statistically significant in influencing postoperative pain.

Randomized Controlled Trial Clinical Trial
The clinical effect of naproxen sodium after arthroscopy of the knee: a randomized, double-blind, prospective study.
The aim of this study was to examine the clinical effect of naproxen sodium after knee arthroscopy. The design was randomized, prospective, and double-blind, with a placebo control group. Patients with preoperative synovial reaction were excluded. ⋯ In patients who had undergone diagnostic arthroscopy naproxen sodium demonstrated a beneficial effect on pain (p < 0.01). At 20 days' follow-up, in the operative group naproxen sodium affected synovial effusion (p < 0.05), range of motion (p < 0.01) and pain (p < 0.05), and walking activity (p < 0.05). No effect was seen in the diagnostic group at 20 days' follow-up.
