    ABSTRACT: Thirty patients, 13 skeletally immature individuals and 17 adults, participated in a prospective study designed to evaluate the effect of isometric quadriceps strengthening exercises on patellofemoral pain. Of the 30 patients with anatomically normal lower extremity alignment and no history of previous knee trauma or surgery, there were 34 knees that had a decrease in peripatellar knee pain with a structured exercise program. One additional patient had a decrease in pain after an arthroscopic lateral release and with continued exercises. An equal number of skeletally immature patients and adults had a decrease in peripatellar knee pain. However, 5 of the 17 adults had to limit their activities, while no adolescent patient had to limit activity. Additionally, eight skeletally immature knees had greater than 5 degrees change in their congruence angles, as measured on Merchant tangential radiographs, over the year-long course of this study. Only one adult knee had a similar radiographic improvement. We recommend immediate action to alleviate patellofemoral pain syndrome, even when extremity alignment is normal. An isometric, progressive resistance quadriceps program with iliotibial band and hamstring stretching exercises is the preferred initial treatment.

    ABSTRACT: The postoperative radiographs of 48 patients who underwent posterolateral in situ fusion for spondylolysis and Grade 1 or less spondylolisthesis over an 11-year period showed healing of the pars defects in 90% of the cases. The patients who showed healing had an average preoperative duration of symptoms of 17 months (mean, 12 months). The five patients whose radiographs showed persistent defects postoperatively were found to have had preoperative symptoms for an average of 47 months (mean, 48 months). This significantly greater (P 0.05) duration of symptoms prior to stabilization was the only variable that proved to be statistically significant. Controversy continues to exist as to the etiology of spondylolysis; however, the ability to heal the defect with lumbar spinal stability certainly supports the theory that the defect is a result of fatigue stresses, which finally manifest as a fracture seen on radiographs as the spondylolytic defect. Posterior spinal stabilization in those patients with symptoms for a period of less than 2 years who have failed conservative management can be expected to heal the pars defects.

    ABSTRACT: A retrospective review was undertaken of 16 adolescent patients (20 feet) with tarsal coalitions. All patients were active in sports and were seen in the Sports Medicine Clinic. Ages ranged from 9 to 17 years (average, 13 years). Failing conservative therapy, 18 feet had resection of the tarsal bar; 1 patient (2 feet) had bilateral extraarticular subtalar arthrodeses. The patients were seen in followup an average of 5.1 years postoperatively (range, 2 to 10 years). An objective ankle/foot score was developed and all patients improved their score postoperatively, with the average score being improved 25%. Nineteen of 20 feet (95%) had excellent or good postoperative results by the ankle/foot score, while 17 of 20 (85%) had an excellent or good subjective result. Two bars in two feet (10%), both in the same patient, recurred. There were six patients with preoperative talar beaking, and all had an excellent or good followup result. All males returned to their previous level of competition in sports, while three female patients (three feet) gave up sports. Resection of tarsal coalitions, even in the presence of talar beaking without other degenerative changes, yields consistently good follow-up results.

    ABSTRACT: Difficulty is frequently encountered in separating the rotator cuff tendons, particularly the subscapularis tendon, from the underlying and often adherent capsule. A safe and quick method of dissecting the tendon from the capsule using a Cobb elevator has proven effective without causing capsular penetration in well over 100 consecutive primary shoulder stabilizations.

    ABSTRACT: Overuse injuries are now well known to sports enthusiasts at any age or level of competition. The seeming explosion of overuse stress fractures of lower extremity bones in high-profile professional basketball players has brought about widespread media attention and a better understanding of the phenomenon of "overuse syndrome" by the public. However, the spectrum of overuse injuries in the child or adolescent athlete has only recently been recognized. These injuries can range from the permanent disability of osteochondritis dissecans of the elbow to the completely nonspecific "growing pains" of active youngsters.
