The fixator consisted of a femoral and tibial threaded pins connected by elastic bands. Follow-up included clinical and radiographic evaluation of patellar stability and tibial rotation.<\/jats:p>\n                  <jats:p>Sixteen of seventeen stifles underwent trochlear intervention. Bilateral central threaded pins were used in 6 cases and unilateral pins in 11. The average fixation duration was 8.2 days. Twelve of the 13 dogs treated during the primary procedure showed no recurrence. Four dogs required revision surgery, which included reapplication of the dynamic fixator. No implant failures were observed.<\/jats:p>\n                  <jats:p>The dynamic external skeletal fixator was effective in managing MPL with rotational tibial deformity. It provided controlled correction with low complication rates and proved useful both as a primary and a revision technique. These findings support further investigation into dynamic fixation as a standardized approach in selected MPL cases with tibial rotational deformity.<\/jats:p>","DOI":"10.1055\/a-2774-4092","type":"journal-article","created":{"date-parts":[[2026,1,7]],"date-time":"2026-01-07T11:56:55Z","timestamp":1767787015000},"page":"320-327","source":"Crossref","is-referenced-by-count":0,"title":["Management of Tibial Rotation in Dogs with Medial Patellar Luxation Using Dynamic Antirotational External Fixation"],"prefix":"10.1055","volume":"39","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2893-3446","authenticated-orcid":false,"given":"Massimo","family":"Petazzoni","sequence":"additional","affiliation":[{"name":"Clinica Veterinaria Milano Sud, Peschiera Borromeo, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2837-7822","authenticated-orcid":false,"given":"Luca","family":"Vezzoni","sequence":"additional","affiliation":[{"name":"Clinica Veterinaria Vezzoni, Cremona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aldo","family":"Vezzoni","sequence":"additional","affiliation":[{"name":"Clinica Veterinaria Vezzoni, Cremona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2026,1,7]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.3415\/VCOT-08-01-0009","article-title":"The prevalence of canine patellar luxation in three centres.
