Postoperative bleeding following notchplasty in anterior cruciate ligament reconstruction: thermal radio frequency versus powered instrumentation.
This study compared postoperative bleeding during anterior cruciate ligament (ACL) reconstruction following notchplasty by power instrumentation with that following radiofrequency. Between January 1998 and April 1998 we prospectively divided 24 consecutive patients undergoing arthroscopic ACL reconstruction with bone-patellar tendon-bone autograft into two groups. Notchplasty was performed by powered instrumentation in group A (n=12) and by radiofrequency in group B (n=12). Two Redi-Vac suction drains were placed, one intra-articularly and the other subcutaneously at the harvest site and tibial tunnel. All drains were removed 48 h postoperatively. The first drainage measurement (end of surgery, 6 a.m. postoperative day 1) showed average total bleeding of 124.16 cc in group A and 65.41 cc in group B (P<0.001); per hour this was 10.21 cc in group A and 5.49 cc in group B (P<0.001). The second drainage measurement (6 a.m. postoperative day 2) showed average total bleeding of 44.55 cc in group A and 17.78 cc in group B (P<0.01); per hour this was 1.85 cc in group A and 0.74 cc in group B (P<0.001). Radiofrequency technology can be used when performing intercondylar notchplasty in ACL reconstruction. As a result of this technique postoperative intra-articular bleeding was significantly reduced.
