“…These lesions, when not properly treated, cause early degenerative changes. 3 Different methods have been described for the surgical treatment of patellar osteochondral lesions; however, there is a limited number of studies on this subject in the literature. Debridement and abrasion represent the most commonly preferred surgical methods because of their easy application and less invasive nature.…”

This study evaluated the functional and clinical outcomes of the subjects with symptomatic osteochondral lesions on articular surface of patella, who were treated with autologous osteochondral transplantation (AOT) method. Study plan: AOT method was applied for the treatment of 14 subjects (eight men and six women; mean age 29.7 years; range 19-49 years) with symptomatic patellar osteochondral lesions between March 2008 and April 2013. After a mean follow-up period of 3.7 years (range 32-80 months), pre-and postoperative clinical and functional evaluations of the patients were performed using Visual Pain Scale (VPS), Lysholm Knee Scoring Scale, and Kujala Anterior Knee Pain Scale. Wilcoxon test was used for statistical evaluation of pre-and postoperative outcomes. Improvement of the lesions was assessed by magnetic resonance imaging (MRI) at year 1 postoperatively at the earliest. Results: The mean lesion size was 1.32 cm 2 (range 0.8-1.8 cm 2). The mean pre-and postoperative VPS values were calculated to be 75.5 + 12.32 (range 46-92) and 17.57 + 10.21 (range 0-40), respectively (p < 0.01). The mean pre-and postoperative Lysholm knee scores were 44.57 + 9.35 (range 26-65) and 80 + 6.9 (range 70-94), respectively (p < 0.01), and the mean pre-and postoperative Kujala anterior knee pain scores were 48.21 + 7.78 (range 38-68) and 78.42 + 7.06 (range 70-96), respectively (p < 0.01). MRI taken at year 1 postoperatively showed that the autograft bone tissue was sufficiently incorporated into the recipient site in all patients; an even articular surface was formed, but the thickness of the cartilage tissue was mostly uneven between the adjacency of the recipient site and the autograft, which caused no negative effect on clinical and functional outcomes. Conclusions: Despite the difference in thickness of the cartilage tissue between the recipient and the donor site, the AOT technique for the treatment of patellar osteochondral lesions resolves the symptoms of the patient and ensures an apparent functional and clinical improvement even if an articular surface could be created.
