A case is presented in which an ossicle was evaluated acutely. Arthroscopy disclosed a tibial osteochondral fracture avulsed by the posterior attachment of the medial meniscus. Treatment was conservative with a good clinical result.

We compared arthroscopic partial menisectomy with limited debridement versus arthroscopic abrasion arthroplasty in patients with osteoarthritis. Group I consisted of 131 knees in 131 patients treated by partial meniscectomy and debridement of loose articular cartilage or removal of loose bodies. All patients had grade 3 or 4 chondromalacia in the affected compartment. ⋯ Fifty percent of Group II subsequently underwent a total knee arthroplasty for salvage at a mean of 3 years following the abrasion procedure. Abrasion arthroplasty appears to offer little benefit over partial meniscectomy and debridement in the degenerative knee. Results of abrasion arthroplasty are unpredictable.

Randomized Controlled Trial Comparative Study Clinical Trial
Bupivacaine use after knee arthroscopy: pharmacokinetics and pain control study.
Bupivacaine (Marcaine) pharmacokinetics were determined in 11 patients receiving the drug intraarticularly after arthroscopic procedures performed on the knee with patients under general anesthesia. Forty milliliters of 0.25% bupivacaine (100 mg) were given as a bolus into the intraarticular space of the knee of each patient. The thigh tourniquet was released 2-3 min after injection and blood samples were obtained 5, 10, 15, 20, 30, 60, 120, 180, 250, and 300 min after tourniquet release. ⋯ Peak levels can be minimized with shorter tourniquet inflation times and with longer injection to tourniquet release intervals. Ninety healthy adult outpatient knee arthroscopy patients also were studied to evaluate the effectiveness of bupivacaine in relieving postoperative knee discomfort when injected immediately postoperatively. The subjects were randomized into four groups: (a) intraarticular injection of saline, (b) intraarticular injection of bupivacaine, (c) subcutaneous injection of bupivacaine at the portal sites, and (d) both intraarticular and subcutaneous injection of bupivacaine.(ABSTRACT TRUNCATED AT 250 WORDS)

Case Reports
Acute pulmonary edema, an unusual complication following arthroscopy: a report of three cases.
Acute pulmonary edema in the young athlete is a rare complication following arthroscopic surgery. It is not related to fluid absorption during arthroscopy, but rather to a brief period of upper airway obstruction. ⋯ Young athletes may be at increased risk for laryngospasm-induced pulmonary edema because they have the ability to generate large negative intrathoracic pressures. This condition must be recognized promptly to minimize morbidity and mortality.
