A rare case of osteonecrosis of patella following quadriceps distractive lengthening for neglected non-union patella

Journal of Orthopaedic Reports
Neglected patella fracture non-unions are extremely rare and contraction of the quadriceps femoris muscle makes it immensely difficult to operate non-union patella after a long time.
