A Student t test of independent samples was used to determine any difference between primary arthroscopic BPTB and hamstring ACL reconstruction procedures with regards to length of procedure, surgical cost, and hospital charges.
Both actual and relative hospital charges between hamstring and BPTB procedures are reported.
Twelve procedures were miscoded, and 100 procedures were not primary endoscopic BPTB or 4-strand hamstring ACL reconstruction or had other major concomitant procedures.
Of the 525 cases reviewed, 471 had BPTB grafts (90%) and 54 had 4-strand hamstring grafts (10%).
ACL reconstruction cases with BPTB took an average of 2 hours and 33 minutes, while cases with hamstring averaged 2 hours and 10 minutes.
Operating room costs for ACL reconstruction cases with BPTB were an average of $565 more expensive per case than ACL reconstruction cases with hamstring.
ACL reconstruction cases with BPTB averaged $7459 in hospital charges while ACL reconstruction cases with hamstring averaged $6444.
Of the 3 surgeons performing both BPTB and hamstring ACL reconstruction, only 1 surgeon performed >1 hamstring procedure.
The hamstring technique had >$1000 per case savings compared with BPTB, whereas outpatient surgery only saved $870 per case.
Reasons why the hamstring procedure might be >20 minutes faster compared with BPTB probably have to do with the harvest of the graft and the closure of the incision.
Although the average BPTB case was 2 hours and 33 minutes, actual surgical time was probably <2 hours.
