Abstract
AIMS
To review the results of a single surgeon series using the above implants looking at functional outcome and implant survivorship.
BACKGROUND
The outcome of ACL reconstruction is multi-factorial. There are many described ways of securing a 4-srandd hamstring ACL graft with no clear gold standard.
METHODS
A prospectively collected database was used to identify patients who had undergone primary ACL reconstruction under a single surgeon. In all cases, a 4 strand hamstring graft was used and secured with Bio-Intrafix and Rigidfix implants (Depuy Mitek). Minimum follow up was 8 months. Those who met the inclusion criteria were contacted via a postal survey using the Lysholm and Tegner questionnaires.
RESULTS
In total 77 patients were eligible for inclusion, (10 females, 67 males) with a mean age of 31 (range 16-56). The response rate was 77% with average follow up of 25 months (range 9-44). The mean Lysholm score was 82.1, with 59% ranking their knee as good or excellent. On average patients dropped 1.8 levels on the Tegner activity rating (means of 7.5 to 5.7). There was a 100% survivorship of implants with no revisions undertaken due to implant failure.
DISCUSSION
The study has shown that this cohort of patients has self-reported outcomes analogous to findings in the literature, and no obvious problem with implants. The quadrupled hamstring graft using Bio-Intrafix and Rigidfix implants produces mid- term functional and activity levels in keeping with the literature standard.
