This Saturday, Celtics guard Kyrie Irving will undergo a procedure to remove two screws implanted in his left patella after the patellar fracture he suffered during the NBA Finals in 2015. Following a mid-March procedure to remove a tension wire that had been implanted at the same time as the screws, pathology indicated the presence of a bacterial infection at the site of the hardware. To ensure that no infection remains in the knee, the screws will be removed. The fracture in Irving’s patella has completely healed, and his knee remains structurally sound. He is expected to make a full recovery in 4-5 months.
