Standard Non Operative Treatment Versus Accelerated Rehabilitation of Achilles Tendon Ruptures

46 question score. Patients are asked to tick boxes labelled between 1 (indicating good function/no problems) and 5 (poor function/significant problems) for each question and the responses are used to calculate a "dysfunction index", a "bother index" and an "overall SMFA score". These will be reported for each group with measure of central tendency (mean/median) and standard deviations/interquartile range.

Incidence of radiologically confirmed thromboembolic events within one year of injury is to be reported for each group.

Ankle motion is to be measured using a goniometer for each patient while subtalar motion is to be clinically assessed. Range of motion will be reported for each group as measure of central tendency (median or mean) and standard deviation or interquartile range.

Measured in centimetres at a point 11 centimetres below the tibial tuberosity. Both sides are measured and the affected (injured) side is compared to the unaffected (uninjured) side for each patient, yielding a relative calf circumference for the affected side. Relative circumference can then be compared across the two groups and reported for each group as a measure of central tendency along with standard deviation/interquartile range..

VAS scored between 0 and 10. Patients asked to circle an integer between 0 and 10 to indicate their pain level, with 0 indicating no pain and 10 indicating severe pain. Scores to be reported for each group (arm of trial) as measure of central tendency (mean/median) and standard deviations/interquartile range.

American Academy of Orthopaedic Surgeons (AAOS) questionnaire (August 2005 version based on version 2.0 Foot and Ankles Outcomes Instrument. This consists of 25 questions with patients asked to indicate the answer that best applies to their situation. Responses are used to calculate a score and scores for each group will be reported as a measure of central tendency (median/mean) with standard deviations/interquartile ranges.

This is a validated score consisting of 10 questions scored 0 to 10 (whole numbers only) with 0 indicating no limitation and 10 indicating maximal limitation. Data to be analysed and presented as measure of central tendency (median/mean) and standard deviations/interquartile ranges for patients in each group.

Time to initial return to work activity measured in days from date of injury. To be reported as the measure of central tendency (mean or median) and standard deviation or interquartile range, for each group (arm of trial). Patients will be asked whether they have returned to work when reviewed at each of the review timepoints listed above, until they answer in the affirmative.

Time to initial return to driving (or use of public transport if non-driver), measured in days from date of injury. To be reported as the measure of central tendency (mean or median) and standard deviation or interquartile range, for each group (arm of trial). Patients will be asked whether they have returned to these activities when reviewed at each of the review timepoints listed above, until they answer in the affirmative.

Time to initial return to sporting activity (if applicable) measured in days from date of injury. To be reported as the measure of central tendency (mean or median) and standard deviation or interquartile range, for each group (arm of trial). Patients will be asked whether they have returned to sporting activities when reviewed at each of the review timepoints listed above, until they answer in the affirmative.

Number of achilles tendon re-ruptures occuring in each group up to one year after injury.

The EQ-5D-5L consists of an EQ-5D index, calculated from scores for 5 domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and the index ranges from -1 to +1. The EQ-5D visual analog scale (VAS) asks patients to self-rate their health state on a scale between 0 and 100. Data to be analysed and presented as measure of central tendency (median/mean) and standard deviations/interquartile ranges for patients in each group. This data is collected for the final 41 patients in this study.

Patients asked "How satisfied are you with your treated ankle?". They must choose one of "Very satisfied"/"satisfied"/"neither satisfied nor dissatisfied"/"dissatisfied"/"very dissatisfied". Responses to be analysed as dichotomous data and ordinal data. This data is collected for the final 41 patients in this study.

Patients asked "Did you have a preference for treatment type for your Achilles tendon injury?" (Choose one of: YES / NO). If Yes, then which modality would you have preferred? (choose one of CAST / BOOT ). Data will be cross tabulated for statistical analysis. This data is collected for the final 41 patients in this study.

As above. An additional time point (post-injury), to be completed at the initial review, was added for the final 41 patients in this study.
