Surgical outcomes of the paratricipital approach (PT) and olecranon osteotomy (OO) for the treatment of distal humerus intra-articular fracture have been reported. However, there is no consensus regarding which approach is better in terms of functional outcomes and complications. This study aimed […]

A 32-year-old patient was diagnosed with a vertical patella fracture nonunion after a bone-patellar tendon-bone (BTB) anterior cruciate ligament reconstruction. In addition, a 1 × 2 × 1 cm patellar bone defect was noticed at the graft harvesting site. The patient was treated surgically with open […]
