The second and fifth flexor digitorum profundus (FDP) tendons from 16 dogs were transected and repaired in Zone II. After 6 weeks of cage activity, the repaired tendons were intentionally ruptured, creating a clinically relevant model for reconstruction. The re\u2010ruptured FDP tendons were then reconstructed using either the clinically standard autologous extrasynovial tendon graft or the Eng\u2010allograft, which had been revitalized with autologous bone marrow\u2010derived mesenchymal stem cells (BMSCs) and synovialized using carbodiimide derivatized synovial fluid (cd\u2010SYN). Following 12 weeks of postoperative rehabilitation, the functional outcomes of the surgical digits were evaluated. The Eng\u2010allograft group exhibited improved digital function, including lower digit work of flexion and reduced adhesion status, while maintaining similar tendon gliding resistance compared to the autograft group. However, the failure load of both the distal and proximal host\/graft conjunctions in the Eng\u2010allograft group was significantly lower than that of the autograft group with higher graft rupture at the host\u2212graft junction. In conclusion, the decellularized allogenic intrasynovial tendon, when revitalized BMSCs and synovialized with cd\u2010SYN, demonstrates positive effects on digital function improvement and adhesion reduction. However, the healing at both proximal and distal graft\/host junctions is far lower than the autograft. Further research is needed to enhance the healing capacity of allograft conjunctions, aiming to achieve a comparable level of healing seen with autografts.<\/jats:p>","DOI":"10.1002\/jor.25854","type":"journal-article","created":{"date-parts":[[2024,4,19]],"date-time":"2024-04-19T11:33:50Z","timestamp":1713526430000},"page":"1923-1932","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cell\u2010based
