Introduction: Patellar tendon rupture is an uncommon injury requiring immediate repair to restablish knee extensor continuity and to allow early motion. The aim of this study was to evaluate the clinical outcomes of surgical repair of patellar tendon rupture and compare the evolution of two groups (acute and chronic ruptures).

Materials and methods: This was a retrospective study of 25 cases operated for patellar tendon rupture and followed in our department. Functional knee evaluation and quality of life were performed.

Results: There were 21 men and 4 women. The average age was 33.60 years. The ruptures were fresh in 17 cases and neglected in 8 cases. There was a significant difference between the range of motion, IKS knee and IKS function when the injured leg was compared to the non-injured leg. In comparison between group with acute rupture and the other with chronic rupture, no significant difference was found in IKS knee, IKS function, SF 12 PCS, SF 12 MCS, pain score and satisfaction. Only the ROM of the knee was significantly different between two groups.

Discussion/conclusion: Patellar tendon ruptures are usually complete and long-term follow-up results indicate excellent function with early repairs. Direct repair of the rupture with cerclage stabilization demonstrates good intermediate to long-term results.
