The aim of this study is to compare the functional outcome of patients who had sustained a rupture of the Achilles tendon and had this repaired using a minimally -invasive repair using either absorbab

Eligibility

Sex/Gender

All

Inclusion criteria

Inclusion criteria: 1. Mid-substance Achilles tendon rupture, diagnosed clinically by the presence of a palpable gap to the Achilles tendon, and increased Achilles Tendon Resting Angle and a calf squeeze test 2. Age 18 - 65 years 3. Active patients with Tegner =5 (Generally participates in sports on regular basis and is recreationally competitive 4. Presenting <15 days following rupture 5. Able to understand the spoken and written English language 6. After consultation wishes to have operative repair of the Achilles tendon rather than non-operative management. 7. Available for 12 months follow up at SATH

Exclusion criteria

Exclusion criteria: 1. Distal Achilles tendon rupture, identified by palpation of the distal stump ending 110 kg & BMI >30 kg/m² owing to obesity giving an increased risk of wound, cast and functional brace complications

Design outcomes

Primary

Measure	Time frame
Plantar flexion strength determined by the Heel-Rise Height Index (HRHI), comparing maximal sustained heel-rise of the injured side to the non-injured side at 12-months following repair	—

Secondary

Measure	Time frame
1. Relative Achilles Tendon Resting Angle measured using a goniometer by the technique of Carmont et al. at the 3 and 12 month time point of routine patient follow up evaluation. 2. The Achilles tendon Total Rupture Score questionnaire (ATRS at 12 months) 3. Activity measured using Tegner Score questionnaire at 12 months 4. Patient Perception of Performance measured using patient interview at 12 months 5. Patient’s acceptability of the received suture measured using patient interview at 12 months 6. Occurrence of complications measured using patient's notes and observation during follow up evaluation (12 months)	—
