In 2006, a survey regarding anterior cruciate ligament (ACL) reconstruction was mailed to physician members of the American Orthopaedic Society for Sports Medicine. A total of 993 responses were received from 1747 possible respondents (57%). The number of ACL reconstructions per year ranged from 1 to 275 (mean = 55). The most important factors in the timing of surgery were knee range of motion and effusion. Bone-patellar tendon-bone (BPTB) autograft was most commonly preferred (46%), followed by hamstring tendon autograft (32%) and allografts (22%). Five years earlier, BPTB grafts were more frequent and hamstring tendon and allografts were less frequent (63%, 25%, and 12%, respectively). A single-incision arthroscopic technique was used by 90%. Most allowed return to full activity at 5 to 6 months, with a trend toward earlier return for BPTB grafts; quadriceps strength was an important factor in the decision. There was limited experience (4%) with double-bundle and computer-assisted ACL reconstruction.Arthroscopic-assisted, single-incision reconstruction using a BPTB autograft fixed with metal interference screws remains the most common technique used for primary ACL reconstruction. In the past 5 years, the use of alternative graft sources and methods of fixation has increased. Consensus regarding the best graft type, fixation method, and postoperative protocol is still lacking.[J Knee Surg. 2009;22:7-12.]

Anterior cruciate ligament (ACL) reconstruction is one of the most commonly performed and researched orthopedic procedures. As technology and comparative research have advanced, surgical practices have changed to achieve a superior outcome. Our group performed a survey of orthopedic surgeons to evaluate current practice trends and techniques as a follow-up to similar surveys performed in 1999 and 2006. In a survey between 2013 and 2014 consisting of 35 questions regarding the surgical technique, graft choice, fixation method, and perioperative care in ACL reconstruction was sent electronically to the members of the American Orthopaedic Society of Sports Medicine and the Arthroscopy Association of North America. Responses were recorded and compared with previous results. Survey responses were received from 824 active surgeons. Of the respondents, 89.4% are subspecialty trained, 98% of which in sports medicine. Preoperatively, full-knee extension was the only "very significant" factor in surgical timing. Approach preference via an arthroscopic-assisted single-incision approach predominated (89%)-similar to earlier results. Bone-patellar-tendon-bone use decreased relative to hamstring allograft at 45 and 41%, respectively. Tibial tunnel placement shifted anteriorly and femoral tunnel placement shifted posterosuperiorly as compared with the results obtained 5 years ago. Femoral drilling through a low medial portal was preferred in 47% of responses, increased from 15%. Preferred fixation on both the tibial and femoral sides was either metal or bioabsorbable interference screws. The use of transfixation pins and other devices decreased. Postoperative rehab protocols did not significantly change, 68.7% preferred full-weight bearing, 55% using a range of motion knee brace locked in extension, 66.4% starting physical therapy 1 week postoperatively, with unrestricted activity at 6 to 9 months. Overall, an increasing trend toward using hamstring autograft and drilling the femoral tunnel through an accessory portal in primary ACL reconstruction was observed. This may reflect recent literature supporting more anatomic reconstruction of the ACL. Considerations including deep venous thrombosis prophylaxis, brace use, timing of surgery, weight-bearing restrictions, physical therapy, graft choice in athletes, and return to activity remained largely unchanged.

Despite a low specificity, the results of this study show the program to be an accurate method for generating a differential diagnosis for knee pain.
