Comparison of lateral ankle ligamentous reconstruction procedures.

The static restraints of various surgical procedures for chronic lateral ankle instability were compared. Forty cadaveric ankles were divided equally into the following five groups: 1) ankles with intact anterior talofibular and calcaneofibular ligaments, 2) ankles with incised anterior talofibular and calcaneofibular ligaments, 3) ankles with Chrisman-Snook procedure, 4) ankles with Watson-Jones procedure, or 5) ankles with modified Broström procedure. All ankles were placed in a mechanical apparatus for anterior drawer stress and inversion stress tests. After each application of force, a radiograph of the ankle joint was taken, and the anterior talar displacement and the talar tilt angle were measured. All procedures reduced anterior drawer and talar tilt when compared with the ankles with incised anterior talofibular and calcaneofibular ligaments. Significant differences were found among the groups for both inversion and anterior drawer stress at all forces, except for the third and fourth groups. The modified Broström group had the least amount of anterior talar displacement and talar tilt angle at all forces. There were no significant differences between the Watson-Jones and the Chrisman-Snook procedures in anterior talar displacement and talar tilt. The modified Broström procedure produced a greater mechanical restraint than either of the other procedures.

Comparison of open and arthroscopically assisted rotator cuff repairs.

Open rotator cuff repair has shown reliable results in terms of pain relief and improved shoulder function. Recently, however, arthroscopically assisted rotator cuff repair has shown promising preliminary results. We compared the results of these two procedures with regard to pain, function, range of motion, strength, patient satisfaction, and return to previous activity. Thirty-seven rotator cuff repairs were evaluated in 36 patients with a minimum followup of 2 years. The open repair group comprised 20 shoulders with an average followup of 3.3 years; the arthroscopically assisted repair group comprised 17 shoulders with an average followup of 3.2 years. Overall, the open repair group had 80% good-to-excellent results and 88% patient satisfaction, and the arthroscopically assisted repair group had 85% good-to-excellent results and 92% patient satisfaction. Shoulder flexion and abduction strength, the size of the tear repaired, and the functional outcome did not differ significantly between the two groups. In general, however, small and moderate-sized tears (< 3 cm) had better functional outcome with arthroscopically assisted repair. The arthroscopically assisted repair group was hospitalized 1.2 days less and returned to previous activity an average of 1 month earlier. In the surgical treatment of symptomatic complete rotator cuff tears, arthroscopically assisted rotator cuff repair is as effective as open repair.
