Abstract
Objective
The aim of this study was to determine the outcome of anterior cruciate ligament (ACL) reconstruction using a patellar tendon bone autograft (one bone block technique).
Method
We retrospectively evaluated a case series of patients who had received arthroscopic ACL reconstructions using patellar tendon bone autograft. Fifty-four (54) ACL reconstructions were evaluated at a mean of 38 months (range 25–62 months). Clinical assessment was made using a modified Lysholm score, documentation of International Κnee Documentation Committee (lΚDC), the anterior knee pain questionnaire of Shelbourne and Trumper, and by ΚΤ-Rolimeter arthrometric analysis. Radiographic assessments were also performed.
Results
Arthrometric analysis showed that 51 knees (94%) were graded Α or Β with a median laxity of 2 mm, postoperatively. The Lysholm score improved postoperatively from 70 to 89. The patellar position in terms of congruence angle did not show any significant change, and the final shortening of the patellar tendon using the Insall–Salvati ratio was 6.07%. Only three patients complained of moderate pain on kneeling, one patient was unable to participate in strenuous works and one patient complained of harvest-site tenderness.
Conclusion
It is concluded that the use of patellar tendon autograft with a single tibial-tubercule bone block and a strip of patellar periosteum have the advantages of being available and comparable in terms of graft size and strength and shows satisfactory results with reduced anterior knee pain.
