- the time of return to light sports activity [ Time Frame: from operation to 1-year follow-up after the surgery ]when the patients are able to do jogging or rapid walk after the surgery, the time will be recorded.
- range of motion (ROM) recovery time [ Time Frame: from operation to 1-year follow-up after the surgery ]the recovery time will be recorded when the ROM is similar to that of the uninjured side.
- recovery time of the single-legged heel rise height (SHRH) [ Time Frame: from operation to 1-year follow-up after the surgery ]The heel rise height is measured as the distance from the ground to the heel when the patient lift the heel while keeping the knee straight. The recovery time is noted when the SHRH is similar to that of the opposite leg.
- visual analogue scale (VAS) [ Time Frame: 2, 4, 6, 8, 10, 12, 14, 16, 24, and 48 weeks after the surgery ]VAS pain score is from 0 to 10, the higher score demonstrate the more severe pain.
- American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score [ Time Frame: 2, 4, 6, 8, 10, 12, 14, 16, 24, and 48 weeks after the surgery ]The AOFAS score ranges from 0 to 100, with a healthy hindfoot receiving 100 points.
- the Achilles tendon Total Rupture Score (ATRS) [ Time Frame: 2, 4, 6, 8, 10, 12, 14, 16, 24, and 48 weeks after the surgery ]The ATRS includes 10 items; each item has a score ranging between 0 and 10 on a Likert scale, with 100 indicating no major limitations.

Ages Eligible for Study: | 18 Years to 60 Years (Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- acute closed single-legged complete Achilles tendon rupture
- age of 18 to 60 years.
Exclusion Criteria:
- patients with prior Achilles tendon rupture or other situations that affected their lower limb functions or tendon healing (e.g., autoimmune disease, diabetes mellitus, systemic corticosteroid treatment).
- an inability to complete our suture technique (e.g., the distance from the rupture site to the Achilles tendon insertion was less than 3.5 cm)
- those without rehabilitation or follow-up outcomes.
