Abstract
Aim: The aim of our study was to evaluate the results of the Soffix Mark I and Mark II hamstring fixation devices, placed transtibially with an “over the top” femoral route when applied to revision anterior cruciate ligament (ACL) surgery secondary to synthetic ligament failure.
Patients and Methods: 29 ACL revisions performed between 1992 and 2000 were evaluated. Twenty six failed prosthetic ligaments, 2 failed semitendinosus/gracilis (STG) and one BTB autografts were revised using hamstring grafts in 26, quadriceps in 2, and patella bone tendon bone (BTB) in 1 patient. Mark I and II fixation devices were employed. Follow up included clinical examination, KT 2000 arthrometric assessment, Lysholm, Tegner and IKDC scoring. The average follow up time was 50 months ±22.4.
Results: Arthrometric examination showed a mean side to side difference (SSD) of 2.98 mm ±1.5. The mean Lysholm score was 86.5 ±10.5 and 21 patients had a B rating (nearly normal) on IKDC scoring, while 3 score A (normal). The mean Lysholm score was 86.5 ±10.5. The lowest clinical scores were noted in 4 multiply operated knees.
Conclusions: We concluded that a revision technique using the STG Soffix fixation device can restore stability with good functional outcomes following failed primary ACL reconstruction. Multiply re-operated knees had the worst functional results despite restoration of stability.
