摘要:
OBJECTIVE:To investigate effectiveness of suture anchor fixation combined with Nice knot strapping via longitudinal patellar drilling in the treatment of patellar inferior pole fractures.
METHODS:A clinical data of 37 patients with unilateral patellar inferior pole fracture who met the selection criteria between June 2017 and June 2021 was retrospectively analyzed. Among them, 17 cases were treated with the suture anchor fixation combined with Nice knot strapping via longitudinal patellar drilling (group A), and 20 cases were treated with the traditional Kirschner wire tension band technique (group B). There was no significant difference in terms of gender, age, body mass index, fracture side, combined medical disease, and preoperative hemoglobin between the two groups ( P>0.05). Operation time, intraoperative blood loss, postoperative complications, fracture healing time, knee range of motion, and knee function Bostman score (range of motion, pain, daily work, muscle atrophy, walking aids, knee effusion, soft leg, and stair climbing) and grading were recorded in both groups at last follow-up.
RESULTS:There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05). All incisions healed by first intention. All patients were followed up 1-2 years, with an average of 1.7 years. X-ray films reexamination showed that all fractures in group A healed, while 2 cases in group B did not heal. There was no significant difference in bone healing time between the two groups ( P>0.05). At last follow-up, the knee range of motion, the range of motion score of Bostman score, total score and effectiveness grading in group A were significantly better than those in group B ( P<0.05). There was no significant difference in the other items of Bostman scores between the two groups ( P>0.05). During follow-up, 2 cases of internal fixation failure and 1 case of internal fixator irritation occurred in group B, and no complication related to internal fixation occurred in group A. The occurrence of complications was significantly lower in group A than in group B ( P<0.05).
CONCLUSION:Compared with the traditional Kirschner wire tension band technique, the suture anchor combined with Nice knot strapping via longitudinal patellar drilling for the patellar inferior pole fractures has the advantages of simple operation, reliable fixation, early flexion and extension activity, and better functional recovery of knee joint.
