Introduction Porous tibial tuberosity advancement (porous-TTA) is a surgical technique used to treat cranial cruciate ligament (CCL) rupture in dogs. However, there is a lack of studies evaluating its application without technical modifications such as the inclusion of a flange- under real-world clinical conditions and with standardized monitoring of bone healing and osteoarthritis progression. This pilot study aims to provide preliminary clinical data on porous-TTA without a flange. Materials and methods Seventeen stifles diagnosed with CCL rupture treated with porous-TTA without a flange were included. Clinical, functional, and radiographic parameters were evaluated preoperatively, at 1 week, and 1 month postoperatively, including bone healing and osteoarthritis progression through osteophyte grading. Results All patients demonstrated satisfactory clinical progress. Early bone healing was observed in all cases, and no radiographic progression of osteoarthritis was noted 1 month after surgery. Tibial crest fissures and non-displaced fractures occurred in 7/17 (41%) and 2/17 (12%) stifles, respectively, but none resulted in clinical signs or required additional intervention. Conclusion Porous-TTA without the use of a flange demonstrated promising short-term functional outcomes. Despite the high incidence of tibial crest fissures and fractures, their clinical impact was minimal. These findings should be interpreted with caution due to the small sample size, absence of a control group, and short follow-up period, and should be considered preliminary and as a useful foundation for designing future long-term and controlled studies.
