Introduction
Successful outcome following patellar tendon rupture requires robust restoration of the extensor mechanism continuity. Rupture of the patellar tendon occurs most commonly in patients younger than 40 years and is the result of an indirect large force generated by contraction of the quadriceps, which is estimated to be at least 17.5 times of body weight.
Patients and methods
Seventeen patients suffered from chronic rupture of the patellar tendon, underwent reconstruction with hamstring tendon autograft and were enrolled in this prospective study. Average age at time of surgery was 30 years (range, 22–36 years). Average follow-up period was 21 months (range, 12–30 months). Patients underwent regular follow-up after clinical and radiographic preoperative and postoperative evaluation.
Results
Analytical results showed satisfactory function after patellar tendon reconstruction with the use of hamstring tendon autografts.
Conclusion
We suggest that the hamstring tendon autograft is a safe, effective, and acceptable choice for patellar tendon reconstruction, and that it affords good ligament reconstruction.
