The Knee
-
Fifty patients who had been admitted to a public hospital in Australia for an elective knee arthroscopy were asked to complete a detailed questionnaire prior to theatre, designed to evaluate patient understanding and satisfaction of the informed consent process. While patients generally felt that they received an appropriate amount of information on the nature of their injury and the actual operative procedure, little information was given on possible complications and post-operative care. ⋯ However, recognition by medical staff of the areas that appear to be poorly explained to patients enables these issues to be addressed. This in turn is likely to improve patient understanding of and satisfaction with the consent process.

Review Case Reports
Bone marrow edema syndrome of the knee: a case report and review of the literature.
The authors present a 45-year-old man with bone marrow edema syndrome (BMES) of the medial condyle of the knee. Early diagnosis of BMES was based upon clinical, bone scintigraphy and magnetic resonance (MRI) findings. ⋯ Within 2 months after the operation, the patient was pain-free and he resumed his previous activities. At 1-year follow-up examination, MRI showed complete resolution of all signal abnormalities; at 3-year follow-up the patient remained symptom-free and with no functional limitations.

Randomized Controlled Trial Clinical Trial
Intra-articular morphine and postoperative analgesia after knee arthroscopy.
The aim of this study was to evaluate the postoperative analgesic effect of intra-articular administration of a low- and a high-dose morphine solution after knee arthroscopy. Thirty patients who underwent diagnostic arthroscopy or arthroscopic meniscectomy were allocated in three groups. At the end of the arthroscopic procedure patients in Group A received intra-articularly 20 ml normal saline (N/S), Group B received 5 mg morphine in 20 ml N/S and Group C received 15 mg morphine in 20 ml N/S. ⋯ Side effects from the central action of opioids were not detected. Although the pain scores in the group of low-dose morphine were lower than in the control group, we failed to detect any significant differences in pain scores among the three groups. There was evidence that a high-dose can cause hyperalgesia.
