Allograft compared with autograft infection rates in primary anterior cruciate ligament reconstruction.

BACKGROUND: Injuries to the anterior cruciate ligament are the most common surgically treated knee ligament injury. There is no consensus regarding the optimal graft choice between allograft and autograft tissue. Postoperative septic arthritis is an uncommon complication after anterior cruciate ligament reconstruction. The purpose of this study was to compare infection rates between procedures with use of allograft and autograft tissue in primary anterior cruciate ligament reconstruction. METHODS: A combined prospective and retrospective multicenter cohort study was performed over a three-year period. Graft selection was determined by the individual surgeon. Inclusion and exclusion criteria were equivalent for the two groups (allograft and autograft tissue). Data collected included demographic characteristics, clinical information, and graft details. Patients were followed for a minimum of 5.5 months postoperatively. Our primary outcome was intra-articular infection following anterior cruciate ligament reconstruction. RESULTS: Of the 1298 patients who had anterior cruciate ligament reconstruction during the study period, 861 met the criteria for inclusion and formed the final study group. Two hundred and twenty-one patients (25.6%) received an autograft, and 640 (74.3%) received an allograft. There were no cases of septic arthritis in either group. The 95% confidence interval was 0% to 0.57% for the allograft group and 0% to 1.66% for the autograft group. The rate of superficial infections in the entire study group was 2.32%. We did not identify a significant difference in the rate of superficial infections between autograft and allograft reconstruction in our study group. CONCLUSIONS: While the theoretical risk of disease transmission inherent with allograft tissue cannot be eliminated, we found no increased clinical risk of infection with the use of allograft tissue compared with autologous tissue for primary anterior cruciate ligament reconstruction.

Post-traumatic catamenial sciatica.

This article presents a unique case of posttraumatic extrapelvic endometriosis presenting as a gluteal mass causing cyclic sciatica. A 38-year-old woman presented with an enlarging right buttock mass over the previous 6 years. She also had symptoms of radicular pain referred to the right leg and foot with sitting and daily activity. Four years prior to noticing the mass, she sustained a gunshot wound through the lower abdomen while 5 months pregnant. Excisional biopsy of the gluteal mass revealed endometrioma. Sciatica is a common and painful disorder that is believed to have an incidence of 40% in the adult population. Sciatica is most often due to intraspinal pathology affecting the lumbar nerve roots. There are many recognized extraspinal etiologies for sciatica in the literature including aneurysms, sciatic hernia, abcess, neoplasm, trochanteric wire, piriformis syndrome, ischial fracture, a posteriorly flexed uterus, and even an intrauterine device following uterine perforation. Similarly, endometriosis is a gynecologic condition that represents a significant health problem for women of reproductive age as it occurs in up to 50% of premenopausal women and 71% to 87% in women with chronic pelvic pain. Although rare, endometriosis has a well known ability to migrate outside of the abdominal cavity and proliferate ectopically under the control of systemic estrogen.

A new operative approach in the correction of external coxa saltans: the snapping hip.

BACKGROUND: External snapping hip is an entity that describes a snap that is felt on the lateral aspect of the hip. Several surgical interventions are described. HYPOTHESIS: The external snapping hip can be corrected with a simple procedure that is minimally invasive and less demanding than other techniques. STUDY DESIGN: This is a retrospective review from June 1994 until January 2002 looking at released external snapping hips. METHODS: There were 16 patients with 17 hips; follow-up was in 15 patients with 16 snapping hips. Twelve patients with 13 hips were contacted by telephone interview, and 3 were followed up by their most recent chart note. All underwent the same procedure performed by the senior author. The questionnaire was conducted at an average of 32.5 months after surgery (range, 9-74 months). For 3 patients, chart-only follow-up was at 6 weeks, 3 months, and 6 months, respectively. RESULTS: Fourteen of 16 hips remained asymptomatic after final surgical release (2 hips needed a second release). All patients contacted by telephone would undergo the same procedure again if faced with the same symptoms. CONCLUSIONS: This technique is simpler than most of those previously described with the benefit of no formal postoperative regimen and comparable results.

Surgical correction of internal coxa saltans: a 20-year consecutive study.

PURPOSE: To report the complications associated with surgical correction of internal snapping hip. STUDY DESIGN: Retrospective review. METHODS: A review of 92 cases of internal coxa saltans (12 bilateral) from 1982 to 2002 was performed to identify complications following primary surgical correction. An inguinal approach was used for iliopsoas tendon fractional lengthening. The average follow-up time per patient was 5.4 years. RESULTS: A total of 40 complications occurred in 32 patients. Complications included persistent hip pain (n = 6), sensory deficit (n = 8), and hip flexor weakness persisting longer than 1 month (n = 3). Additionally, painful bursa formation (n = 1), hematoma requiring reexploration (n = 1), and superficial infection (n = 1) were noted. Some patients developed recurrent snapping after a 3-month snapping-free interval (n = 9), and some patients never had complete resolution of snapping and were considered failures (n = 11). Of these failures/recurrences, 8 patients had a second tenotomy with 4 failures. Two had a third tenotomy, with 1 failure. CONCLUSIONS: In this series, primary iliopsoas tendon lengthening in patients with internal coxa saltans was without any complication in only 60% of patients; however, overall patient satisfaction was 89%.
