Miniarthrotomy versus arthroscopic-assisted anterior cruciate ligament reconstruction with autogenous patellar tendon graft.

The purpose of this study was to determine whether two groups of patients showed any early (6 months postoperative) clinical differences when treated by arthroscopic-assisted or miniarthrotomy anterior cruciate ligament (ACL) reconstruction. Fifty-two consecutive arthroscopic-assisted ACL reconstructions (Group I) were matched with 52 miniarthrotomy ACL reconstructions (Group II). An autogenous midthird patellar tendon was used in all reconstruction procedures. Group I patients were operated on by one surgeon (A.C.R.) and all Group II patients by another (K.D.S.). Both groups were similar with regard to age, sex, injury, chronicity, and previous knee surgical procedures. All patients were treated according to the same postoperative rehabilitative protocol (emphasizing early motion, immediate full passive extension, early functional activity) and evaluated on follow-up by the same personnel and protocol. Data collection included injury and surgery dates; total surgery and tourniquet times; length of hospital stay; drain output; inpatient pain medications used; follow-up range of motion at 1.5, 2.5, and 6 weeks postoperative; KT-1000 arthrometer measurements at 10, 16, and 26 weeks; and isokinetic measurements at 10 and 16 weeks postoperative. Results indicated that follow-up range of motion and KT-1000 measurements showed no statistical difference between groups. Isokinetic average scores for quadriceps strength at 180 degrees/s showed no differences at 10 and 16 weeks. The study suggested that ACL reconstruction with midthird patellar tendon performed by skilled surgeons using either open or arthroscopic-assisted techniques combined with an aggressive postoperative rehabilitation protocol will yield similar acceptable early clinical results.

Emergency transport of AS-1 red cell units by pneumatic tube system.

We present a study in which 14 units of AS-1 red blood cells (AS-1RBC) were transported by the Trans-Logic 620 (Denver, CO) pneumatic tube system to determine whether the system could be used without risk of significant hemolysis. Using standard hematologic parameters we detected negligible hemolysis and conclude that the Trans-Logic 620 system can be used to transport AS-1RBC. This may provide time- and labor-saving benefits generalizable to more than 250 U.S. hospitals which presently operate the Trans-Logic 620.

Posterior malleolar fractures of the ankle associated with external rotation-abduction injuries. Results with and without internal fixation.

Thirty-eight patients in whom a fracture of the posterior malleolus was shown to comprise 25 per cent or more of the articular surface on the lateral radiograph were followed for an average of forty-four months (range, twenty-four to ninety-nine months). All injuries were judged to be a result of external rotation or abduction of the talus. Fifteen patients had fixation of the posterior malleolus, and twenty-three did not. Open reduction and internal fixation was carried out on all associated fractures of the medial and lateral malleoli. Satisfactory reduction of the posterior malleolus was often achieved when the fibula was reduced, and frequently this was maintained despite the absence of fixation. No posterior subluxation of the talus occurred in either group. No statistically significant difference was noted between the clinical results with and without fixation.
