To explore the clinical application of lockedge suspension combined with three steel wires vertical fixation in comminuted fracture of inferior pole of patella. From August 2016 to May 2019, 23 patients with comminuted fracture of the lower pole of the patella, including 14 males and 9 females, were treated with lockedge suspension combined with three steel wires vertical fixation. The age ranged from 34 to 68 (55.0±1.2) years. One year after operation, the pain and function were evaluated by pain visual analogue scale(VAS) and knee flexion and extension range of motion, and the clinical efficacy was evaluated by Lysholm knee score standard. All 23 patients were followed up for 12 to 14, with a mean of(13.0±0.5) months. One patient had skin irritation by the tail of the steel wire, and the rest had no postoperative complications such as incision infection, internal fixation loosening and fracture displacement. The fractures of 23 patients were healed, and the healing time was 10 to 14 weeks with a mean of(12.0±1.1) weeks. The VAS score decreased from 7.96±0.93 before operation to 0.83±0.65 one year after operation. The range of knee flexion and extension activities increased from(20.30±8.69) ° before operation to 1 year after operation(127.39±6.55) °. Lysholm knee score increased from 18.48±4.00 before operation to 96.09±4.91 one year after operation(P<0.05). The treatment of comminuted fracture of the lower pole of patella by lockedge suspension combined with three steel wires vertical fixation has reliable fixation and high fracture healing rate. It can meet the requirements of rapid rehabilitation and functional exercise, and the early clinical effect is satisfactory.
