Labral reconstruction with tendon allograft: histological findings show revascularization at 8 weeks from implantation.

This description shows the histological findings of a peroneus brevis tendon allograft used for labral reconstruction, implanted 8 weeks before being retrieved due to a postoperative complication unrelated to the graft. As far as we have knowledge this is the first description about revascularization of an allograft used for hip labral reconstruction. The histological report of the removed peroneus brevis tendon allograft shows evidence of vascular ingrowth represented by small vessels with a thin muscular wall in all layers of the graft and cellular migration mainly represented by mature fibroblasts.

Reconstruction of Massive Posterior Nonrepairable Acetabular Labral Tears With Peroneus Brevis Tendon Allograft: Arthroscopy-Assisted Mini-Open Approach.

Many of the described labral-reconstruction procedures are purely arthroscopic. This approach only allows segmentary reconstructions. For more extensive reconstructions, surgical dislocation of the hip still represents the more suitable approach. We present an arthroscopy-assisted procedure combined with an anterior mini-open approach, which could be considered for reconstruction of nonrepairable labral lesions located in the posterior aspect of the acetabulum and massive reconstructions in cases of global-pincer femoroacetabular impingement and protrusio acetabuli. Our technique saves the morbidity that might be related to the surgical dislocation of the hip and incorporates a peroneus brevis tendon allograft. This option may restore the anatomy and labral function without morbidity at the donor site, as well as remove graft length restrictions during massive reconstructions.

Multicenter Outcomes of Endoscopic Pubic Symphysectomy for Osteitis Pubis Associated With Femoroacetabular Impingement.

PURPOSE: To investigate outcomes of athletic patients treated with concurrent femoroacetabular impingement (FAI) and osteitis pubis (OP) surgery including endoscopic pubic symphysectomy. METHODS: We performed a multicenter retrospective case series of 7 consecutive adult patients (4 men) with a mean age of 33 years with symptomatic FAI and OP who underwent arthroscopic surgery for the former and endoscopic pubic symphysectomy for the latter with a mean follow-up period of 2.9 years (range, 2.0 to 5.0 years). The visual analog scale (VAS) score, the Non-Arthritic Hip Score (NAHS), and patient satisfaction were measured. Complications and revision surgical procedures were reported, and preoperative and postoperative radiographs were assessed. RESULTS: The mean preoperative VAS score of 6.7 (range, 4 to 8) improved to a mean postoperative VAS score of 1.5 (range, 0 to 7) (P = .03). The mean preoperative NAHS of 50.2 points (range, 21 to 78 points) improved to a mean postoperative NAHS of 84.7 points (range, 41 to 99 points) (P = .03). The mean patient satisfaction rating was 8.3 (range, 3 to 10). Two male patients had postoperative scrotal swelling that resolved spontaneously. There were no other complications. Preoperative and postoperative radiographs showed no anterior or posterior pelvic ring instability. One patient underwent pubic symphyseal arthrodesis because of continued pain. CONCLUSIONS: Endoscopic pubic symphysectomy is a minimally invasive treatment for athletic OP with encouraging early outcomes that may be performed concurrently with surgery for FAI in co-afflicted patients. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
