Abstract
Aim The aim of this study was to compare immediate weightbearing mobilisation to traditional plaster casting in the rehabilitation of acute repaired Achilles tendon ruptures.
Methods 48 patients with acute repaired Achilles tendon ruptures consented to enter the trial. Patients were randomised into two groups. The treatment group were fitted with an off-the-shelf carbon-fibre orthotic and were mobilised fully weightbearing. The equinus position of the ankle joint was reduced over a period of 8 weeks and the orthotic was then removed. The control group were immobilised in traditional serial equinus plaster casts. The equinus position of the cast was reduced over the same 8 week period with weightbearing for only the last 2 weeks. The primary outcome measure was return to the patient’s normal activity level. An independent observer, blind to treatment, recorded secondary clinical, anthropometric and patient-centred outcomes. Follow-up was for one year.
Results There were 23 patients in the treatment group and 25 in the control group. Results show median in weeks (95% C.I.), p-values are based upon a log-rank test.
Return to sport was 39.0 (18.0 to 60.0) in the treatment group and 26.0 (40.0 to 90.0) in the control group, p = 0.341.
Return to normal walking was 12.0 (10.0 to 18.0) in the treatment group and 18.0 (18.0 to 22.0) in the control group, p < 0.001.
Return to stair climbing was 13.0 (10.0 to 15.0) in the treatment group and 22.0 (18.0 to 22.0) in the control group, p < 0.001.
Return to work was 9.0 (2.0 to 9.0) in the treatment group and 4.0 (1.0 to 13.0) in the control group, p = 0.984.
There were 2 re-ruptures of the tendon in the treatment group. One occurred when the patient slipped on ice whilst wearing the orthotic. The other whilst running 3 months after the initial injury. One patient who had an augmented tendon repair and then plaster casting, required plastic surgery for a major wound complication. In addition, there were 8 minor wound-related complications in the control group and 6 in the treatment group.
Conclusion Immediate weightbearing mobilisation provides practical advantages to patients after Achilles tendon repair. The median return to activity was significantly shorter in the treatment group for return to normal walking and return to stair climbing but not for return to work or sporting activity.
