Objectives: Revision anterior cruciate ligament (ACL) reconstruction is associated with poorer outcomes and
higher rerupture rates when compared to primary ACL reconstruction. There is also a significant heterogeneity in
surgical technique, number of stages, and graft options. We report a large single surgeon case series with
hamstring autograft as a graft option.
Methods: Observational series of revision ACL reconstructions performed by the senior author between 2005 and
2015 was carried out. Chart reviews and clinic follow-ups were performed with the following recorded – re-rupture
rate, radiographic grading of osteoarthritis, KT-1000 arthrometer test, IKDC outcome scores and knee range of
motion. All patients underwent single bundle four-strand hamstring autograft performed in one stage with use of
new tunnels in majority of the cases.
Results: 66 patients underwent hamstring autograft one-stage revision ACL reconstruction by Dr Jens Buelow.
Chart review was carried out on all patients, and 26 (39%) were followed up in clinic and/or by phone with a mean
follow up of 4.7 years. Outcomes included re-rupture rate of 4.5%, reoperation rate of 12%, mean visual analogue
scale score of 7.6, mean side-to-side difference of 2.6mm for KT-1000 arthrometer test, and mean IKDC score of
79. Of the 17 patients with radiographs, 40% had moderate osteoarthritis (grade 2 or 3) at follow-up.
Conclusion: Revision ACL reconstruction can result in a satisfactory outcome when performed with a hamstring
autograft in one stage.
