摘　　要：BACKGROUND Gout is a disease characterized by hyperuricemia,and resultant deposition of uric acid crystals in tissues.While typically manifested as intraarticular crystals or tophi,gout can also cause pathology at entheses.Gouty deposition within tendinous structures put them at risk for traumatic and degenerative rupture.Furthermore,allografts can also be at risk of rupture in the setting of severe gout.We present the case of a 56-year-old female with severe gouty disease who sustained a re-rupture of a patellar tendon allograft reconstruction.CASE SUMMARY A 56-year-old female presented to clinic after feeling her left knee pop and collapse beneath her while descending stairs.She had a history of tophaceous gout and left patellar tendon rupture with reconstruction and multiple revisions over the course of 19 years.This patient presented with pain and extensor lag.A magnetic resonance image demonstrated a ruptured patellar tendon allograft reconstruction and avulsion fracture at the tibial tubercle.The patient was treated with a novel intervention of Achilles allograft with bone block in a unique configuration with a dermal allograft incorporated into the reconstruction.She was made non-weight bearing in the operative extremity in extension for the first four weeks postoperatively and was then progressed to active flexion over the course of eight weeks.At twelve weeks,she was able to fully extend her operative knee and at five months she was resuming her normal activities and exercises.CONCLUSION Failed patellar tendon reconstruction due to gouty infiltration is treated with dermal allograft augmented Achilles tendon reconstruction with bone block.
