Report of experience in 190 patients with the use of closed suction drainage in arthroscopic knee procedures.

摘要

The goal of this study is to report our experience with the use of suction drainage for various arthroscopic knee procedures. One hundred and ninety patients who underwent arthroscopic knee procedures participated in the study, and were divided into two groups (Group 1: Suction drainage, Group 2: No suction drainage). For every patient, the following parameters were recorded: age, gender, operative time, tourniquet or pump use, the amount of fluid collected in the hemovac drain, presence of meniscal tear, type of the operative procedure, date of the operation, and presence of effusion at the follow-up. Statistical analysis was performed to detect any significant statistical difference between the amount of fluid collected in the hemovac drain and the other mentioned parameters in Group 1; and these patients were divided into four subgroups to facilitate the statistical evaluation between the procedures and the amount of fluid collected in the hemovac drain. The partial meniscectomy subgroup had significantly lower amounts of collected fluid when compared to the subtotal meniscectomy subgroup. Drilling of the osteochondral faces led to significantly higher amounts of fluid when compared to non-drilling cases. Use of an infusion pump during surgery and shorter operation time led to lower amounts of fluid to be collected. No case in either main group suffered from effusion at the follow-up. Our investigation demonstrated that in different arthroscopic interventions, variable amounts of fluid can be collected in the hemovac drains. Subtotal meniscal resection, drilling of the osteochondral faces and longer duration of the operation increase the amount of fluid. In cases of partial meniscal resection and/or chondral debridement, limited synovial and plica resection, suction drainage is unnecessary.
