Abstract:
OBJECTIVETo investigate the incidence and variation of tunnel enlargement after anterior cruciate ligament (ACL) reconstruction.
METHODSACL reconstructions using hamstring tendons were performed in 58 patients (58 knees) in the study. MRI scans were taken in a consistent manner at 1, 3, 6, 12 and 24 months after surgery to measure tibial and femoral tunnel expansion.
RESULTSFemoral tunnel enlargement was observed in 9 knees (9/58, 15.5%); Tibial tunnel enlargement was found in 12 knees (12/58, 20.7%). Of those with enlarged bone tunnels, there was no significant difference of tunnel diameters between 1 and 3 months after surgery (P>0.05). Six, 12 and 24 months postoperatively, the average tunnel diameters were larger than those of 1 or 3 months after surgery (P<0.05), however, no significant difference was found in between the tunnel diameters 6, 12 and 24 months postoperatively either (P>0.05).
CONCLUSIONTunnel expansion mainly occurs during 3 to 6 months after surgery, and it remains basically unchanged between 12 and 24 months postoperatively.
