Double-bundle transtibial posterior cruciate ligament reconstruction with a tendon-patellar bone-semitendinosus tendon autograft: clinical results with a minimum of 2 years' follow-up.

PURPOSE: The purpose of this study was to evaluate the clinical and subjective outcomes after arthroscopic-assisted double-bundle posterior cruciate ligament (PCL) reconstruction. METHODS: A series of 15 patients with grade III isolated chronic PCL tears underwent double-bundle PCL reconstruction. Of these patients, 8 (53%) had simultaneous fractures. The mean time from accident to surgery was 10.8 months (range, 8 to 15 months). The mean age at the time of surgery was 28.2 years (range, 17 to 43 years). All of the patients reported knee insecurity during activities of daily living or light sporting activities, with associated anterior knee pain in 5 patients. Preoperatively, posterolateral or posteromedial corner injuries were ruled out through accurate clinical examination. The knees were assessed before surgery and at a mean follow-up of 3.2 years (range, 2 to 5 years) with a physical examination, 4 different rating scales, and stress radiographs obtained with a Telos device (Telos, Marburg, Germany). RESULTS: Postoperative physical examination revealed a reduction of the posterior drawer and tibial step-off in all cases, although the posterior laxity was not completely normalized. Nevertheless, the patients were subjectively better after surgery. The subjective International Knee Documentation Committee score was significantly ameliorated. With regard to the objective International Knee Documentation Committee score, 6 knees (40%) were graded as abnormal because of posterior displacement of 6 mm or greater on follow-up stress radiographs with the Telos device. On the Lysholm knee scoring scale, the score was excellent in 13% of patients and good in 87%. The mean score on the Hospital for Special Surgery knee ligament rating scale was 85.8. The Tegner activity score showed an amelioration after surgery, but no patient resumed his or her preinjury level of activities. The postoperative stress radiographs revealed an improvement in posterior instability of 50% or more in all but 3 knees (20%). CONCLUSIONS: Our technique of double-bundle PCL reconstruction produced a significant reduction in knee symptoms and allowed the patients to return to moderate or strenuous activity, although the posterior tibial translation was not completely normalized and our results appear to be no better than the results of single-bundle PCL reconstruction. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Tendon transfers for radial nerve palsy: use of superficialis tendons for digital extension.

Since 1959, 22 patients have had wrist extension restored by transfer of the pronator teres to the extensor carpi radialis longus and brevis, common finger extension by transfer of the superficialis of the long finger, independent thumb and index finger extension by transfer of the superficialis of the ring finger, and abduction of the thumb by transfer of the flexor carpi radialis at the wrist joint level. Twenty-one of 22 patients have been evaluated from 8 months to 15 years after operation, with an average follow-up of 4.5 years. By our new system of evaluation, there were 10 excellent results, six good results, five fair results, and all patients improved. Sixteen patients obtained full, independent thumb-index finger extension, three had fair function, and two obtained thumb-index extension by tenodesis of the transfer. This procedure allows full metacarpophalangeal extension independent of wrist position, provides thumb-index finger extension independent of the ulnar three digits, and maintains the dorsal-radial-to-volar-ulnar plane of functional motion of the wrist by retaining the flexor carpi ulnaris.
