All functional tests were performed on the involved ankle of the ATR group, and at the matched side of healthy age, gender, and activity-level control group subjects. <jats:italic><jats:bold>Methods<\/jats:bold>:<\/jats:italic> Fifteen men in each group were evaluated for medial and lateral gastrocnemius, soleus, tibialis anterior, and peroneus longus muscle activation during modified star excursion balance test and heel-rise test performance. The weight-bearing lunge test (ankle dorsiflexion) and heel-rise test distance (ankle plantar flexion) also determined weight-bearing, active ankle mobility magnitudes. The Achilles Tendon Total Rupture Score and Foot and Ankle Outcome Score provided patient-reported outcome perceptions specific to Achilles tendon rupture and comprehensive foot and ankle symptoms and function, respectively. <jats:italic><jats:bold>Results<\/jats:bold>:<\/jats:italic> Medial (<jats:italic>P<\/jats:italic>\u2009=\u2009.005) and lateral (<jats:italic>P<\/jats:italic>\u2009=\u2009.012) gastrocnemius displayed greater activation amplitudes in the ATR group during the star excursion balance test, and peroneus longus displayed greater activation amplitudes during the heel-rise test (<jats:italic>P<\/jats:italic>\u2009=\u2009.006). The star excursion balance test reach distance was comparable between groups. Active weight-bearing ankle plantar flexion (heel-rise test) and dorsiflexion (weight-bearing lunge test) mobility magnitudes were lower in the ATR group. <jats:italic><jats:bold>Conclusions<\/jats:bold>:<\/jats:italic> Subjects who underwent endoscopy-assisted percutaneous ATR had reduced active weight-bearing ankle dorsiflexion and plantar flexion mobility magnitudes and greater gastrocnemius and peroneus longus neuromuscular activation when performing the same tasks as healthy control group subjects. As surgical approaches evolve to less invasive, soft tissue preserving methods with less tissue morbidity and faster healing, rehabilitation approaches may likewise need to evolve. <jats:italic><jats:bold>Level of Evidence<\/jats:bold>:<\/jats:italic> Level III.<\/jats:p>","DOI":"10.1123\/jsr.2022-0064","type":"journal-article","created":{"date-parts":[[2023,1,23]],"date-time":"2023-01-23T10:35:45Z","timestamp":1674470145000},"page":"305-314","source":"Crossref","is-referenced-by-count":5,"title":["Altered Ankle Muscle Activation at 2-Year Post Achilles Tendon Repair: An Age, Gender, and Activity Level-Matched Comparison With Healthy Subjects"],"prefix":"10.1123","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9586-4041","authenticated-orcid":true,"given":"F\u0131rat","family":"Tan","sequence":"first","affiliation":[{"name":"Hacettepe University Faculty of Physical Therapy and Rehabilitation, Department of Musculoskletal Rehabilitation, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8315-8465","authenticated-orcid":true,"given":"Hande","family":"Guney-Deniz","sequence":"additional","affiliation":[{"name":"Hacettepe University Faculty of Physical Therapy and Rehabilitation, Department of Musculoskletal Rehabilitation, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2298-0807","authenticated-orcid":true,"given":"Gulcan","family":"Harput","sequence":"additional","affiliation":[{"name":"Hacettepe University Faculty of Physical Therapy and Rehabilitation, Department of Sports Rehabilitation, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2433-8199","authenticated-orcid":true,"given":"Burak","family":"Ulusoy","sequence":"additional","affiliation":[{"name":"Cankiri Karatekin University, Faculty of Health Sciences, Department of Physiotherapy and Rehabilitation, Cankiri, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6379-669X","authenticated-orcid":true,"given":"G\u00fcrhan","family":"D\u00f6nmez","sequence":"additional","affiliation":[{"name":"Hacettepe University, Faculty of Medicine, Department of Sports Medicine, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9033-5020","authenticated-orcid":true,"given":"John","family":"Nyland","sequence":"additional","affiliation":[{"name":"Spalding University, Kosair Charities College of Health and Natural Sciences, Louisville, KY, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1380-7500","authenticated-orcid":true,"given":"Mahmut N.","family":"Doral","sequence":"additional","affiliation":[{"name":"Former Chair of Hacettepe University Faculty of Medicine Orthopedics and Traumatology Department, Ankara, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"100","reference":[{"issue":"1","key":"r1","series-title":"Scand J Med Sci Sports","first-page":"e133","article-title":"Epidemiology of Achilles tendon ruptures: increasing incidence over a 33-year period","volume":"25","author":"Lantto I","year":"2015","unstructured":"Lantto I, Heikkinen J, Flinkkila T, Ohtonen P, Leppilahti J.
