National Hockey League (NHL), Major League Soccer (MLS), and US Olympic/World Cup Ski/Snowboard (Olympic) athletes receive orthopedic care from a select group of surgeons. There are 30 NHL teams, 19 MLS teams, 1 Olympic ski team, and 1 Olympic snowboard team, for a total of 51 teams and a rough total of 2229 athletes (1500 NHL, 570 MLS, 159 Olympic).1
Studies have shown that MLS athletes and X-Game skiers and snowboarders have performed well on return to sport (RTS) after anterior cruciate ligament (ACL) reconstruction.2,3 However, the techniques, graft choices, and rehabilitation protocols used to return these elite athletes to their preinjury level of performance have not been elucidated. It is unclear if the treatment given to these elite athletes differs from that given to recreational athletes and nonathletes. Bradley and colleagues4 examined how 32 NFL team orthopedists treated ACL tears, and Erickson and colleagues5 recently surveyed NFL and National Collegiate Athletic Association (NCAA) team physicians to determine practice patterns (eg, surgical techniques, graft choices, postoperative protocols) in treating ACL tears. Until now, however, no one has examined NHL, MLS, or Olympic team orthopedic surgeons’ practice patterns as they relate to ACL reconstruction.
We conducted an online survey of NHL, MLS, and Olympic team orthopedic surgeons to determine practice patterns relating to ACL reconstruction in elite athletes. Given the practice patterns of surgeons in our practice, we hypothesized that the surveyed surgeons treating these elite athletes would most commonly use bone–patellar tendon–bone (BPTB) autograft with a single-bundle technique. We also hypothesized that they would permit RTS without a brace at a minimum of 6 months after surgery, with a normal physical examination, and after successful completion of a structured battery of RTS tests.
Materials and Methods
On the SurveyMonkey website (http://www.surveymonkey.com), we created a 7-question base survey, with other questions added for the NHL and MLS surveys (Figure 1). We sent this survey to 94 team orthopedic surgeons (41 NHL, 26 MLS, 27 Olympic) identified through Internet searches and direct contact with team public relations departments. The survey was approved by MLS and NHL research committees. In 2013, each survey was sent out 5 times. The response rates for each round are shown in Figure 2. All responses remained confidential; we did not learn surgeons’ identities. Data were collected and analyzed through the SurveyMonkey website. Each surgeon was instructed to respond to all relevant questions in the survey. The survey was designed such that the participant could not submit the survey without answering all the questions. Descriptive statistics were calculated for each study and parameter analyzed. Continuous variable data are reported as means and standard deviations (weighted means where applicable). Categorical data are reported as frequencies with percentages.
Results
Of the 94 team orthopedic surgeons surveyed, 47 (50%) responded (NHL, 49%; MLS, 50%; Olympic, 52%). Mean (SD) experience as a team physician was 7.73 (5.33) years (range, 2-20 years) for NHL, 6.77 (6.64) years (range, 2-20 years) for MLS, and 1.14 (0.36) years (range, 1-10 years) for Olympic. Mean (SD) number of ACL reconstructions performed in 2012 was 101 (51) for NHL (range, 50-200), 78 (38) for MLS (range, 20-150), and 110 (105) for Olympic (range, 25-175) (Table 1). Of the 47 surgeons, 42 (89.4%) used autograft in the treatment of elite athletes, and 5 (10.6%) used allograft. Autograft choices were BPTB (n = 33; 70.2%), 4-strand semitendinosus (n = 7; 14.9%), and quadriceps (n = 2; 4.3%); allograft choices were 4-strand semitendinosus (n = 4; 8.5%) and BPTB (n = 1; 2.1%) (Table 2).
Of the 40 surgeons (85.1%) who indicated they would use autograft in 25-year-old recreational athletes, 25 (53.2%) would use BPTB, 13 (27.7%) would use 4-strand semitendinosus, and 2 (4.3%) would use quadriceps; of the 7 who indicated they would use allograft, 4 (8.5%) would use 4-strand semitendinosus, and 3 (6.4%) would use BPTB. In the NHL and MLS surveys, 19 surgeons (57.6%) indicated they would use autograft (6 would use BPTB, 13 would use 4-strand semitendinosus), and 14 (42.4%) would use allograft (7 would use BPTB, 5 would use Achilles, and 2 would use tibialis anterior) in 35-year-old recreational athletes.
Twenty-one surgeons (44.7%) were drilling the femoral tunnel through a transtibial portal, 36.2% through an anteromedial portal, and 12.8% using a 2-incision technique. All surgeons indicated they were using a single-bundle technique in ACL reconstruction. Thirty-three surgeons (70.2%) did not recommend a brace for their elite athletes on RTS. Olympic team surgeons had the highest rate of brace wear in RTS (50%, both skiers and snowboarders); NHL and MLS surgeons had significantly lower rates (25% and 15.4%, respectively) (Table 3).
