Abstract
Purpose
To evaluate the prospective long-term clinical and functional results of patients undergoing osteochondral autologous transplantation surgery (OATS) of the patella.
Methods
Patients with symptomatic full-thickness osteochondral lesions of the patellar treated with OATS were evaluated prospectively using clinical and functional scores (Lysholm, Kujala, Fulkerson, Tegner, and SF-36) at three different periods: preoperatively, 24 months, and a final minimum follow-up period of 60 months (60-138).
Level of evidence: IV
Results
Thirty-four patients with mean age of 35.5 (25-57 years) were evaluated with a mean follow-up of 90.9 months (60-138), of which 19 were female (56%). Among them, 30 received one oste-ochondral plug and 4 received two (mean size of lesion was 1.0 cm2). The Lysholm scores were: 57.8; 79.9 and 77.9, preoperatively, at 2 years, and at the final follow-up, respectively (p<0.001; p=0.085); The Fulkerson scores were 54.4; 81.3; and 79.7 (p<0.001; p=0.883); the Kujala scores were 55.5; 79.5; and 78.9 (p<0.001), respectively. SF-36 functional questionnaire, showed statistical improve-ments for functional capacity (p<0.001), physical aspects (p<0.001), pain (p<0.001), vitality (p<0.001) and emotional aspects (p<0.001); only general health status showed no statistical improvement (p=0.326). Tegner score was calculated only for the preoperative period and final follow-up, 6.59 and 5.47, respectively (p=0.007). The prevalence of failure, defined as the need for another surgical proce-dure, was 17.6%.
Conclusion
OATS is an effective technique for the treatment of osteochondral defects of the patella, with the short-term results maintained at follow-up of 5 to 10 years.
