Abstract
Introduction: Patellar tendon is one of the main donor sites for graft. Postoperatively, during the healing procedure there are changes, which we recorded and combined them with the clinical image respectively.
Material and Methods: During the period 1998–2001 in Sports Injury Unit, we operated for Anterior Cruciate Ligament insufficiency with autologous Bone Patellar Tendon Bone (BPTB) graft 265 patients. We used autologous BPTB graft from the middle third. We got near the two parts after taking the graft and we sewed very well the peritendon fascia. All patients, with few differentiations, followed the same rehabilitation program.
Seventy -seven of them (44 men and 33 women ranging from 17 to 44 years -mean: 24,3 years), were imaged postoperative with MRI at specific intervals from the operation between 3–36 months. In the same time we checked the patients clinically.
Results: No one study can answer which is the exact time of satisfying or complete healing. Our study shows elements of scar tissue in the middle third of patellar tendon which is decreasing given time. After the 12th month, the proportion between healthy and scar tissue changes and healthy tissue become dominant. But in some cases scar is still existing even after 36 months. The clinical problems such as anterior knee pain are not existed after the 8th postoperative month.
Conclusion: In conclusion, we can say that “regeneration” and healing of patellar tendon occurs mainly during the first postoperative year, but it doesn’t stop after this time. So, we couldn’t recommend this donor site for revision reconstruction before the completion of one year postoperatively.
