Reconstructing a Patellar Tendon Rupture Neglected for 14 Years When Anatomic Restoration Is Not Possible: A Case Report.

CASE: This case highlights the utility and outcomes of an Achilles tendon bone-block allograft in reconstructing the patellar tendon of a 44-year-old man in the setting of a high-riding, irreducible patella after a chronic patellar tendon rupture of 14 years.

CONCLUSION

In cases of a neglected patellar tendon rupture with an irreducible high-riding patella, an Achilles tendon bone-block allograft can provide the length and tissue necessary to reconstruct the extensor mechanism. Although reconstruction may not be anatomic, patients can still experience great subjective and objective functional improvement with restoration of the extensor mechanism even after delayed reconstruction.
