  • THE TREATMENT OF FRACTURE OF PATELLA BY INTERNAL FIXATION WITH TENSION BAND FROM MUSCULOFASCIAL TENDON

    In the study of the efficacy of internal fixation with tension band of musculofascial tendon in the treatment of fracture of patella, 52 cases were reported. After a following-up of 6 months to 13 months the bone healing was observed, in 7.5 weeks in average, and the function of the knee joint had recovered to normal or almost normal. It was concluded that the treatment of fracture of patella by internal fixation with tension band from musculofascial tendon was a ideal and practicable method.

  • Clinical application of anatomical locking plate in treatment of Rockwood type Ⅰ-Ⅲpatella fractures

    Objective To investigate the effectiveness of anatomical locking plate in the treatment of Rockwood type Ⅰ-Ⅲ patella fractures. Methods The clinical data of 16 patients with patella fractures who were admitted between November 2021 and January 2023 and met the selection criteria was retrospectively analyzed. There were 14 males and 2 females, with an average age of 44.5 years (range, 19-72 years). Causes of injuries included tumble in 12 cases and traffic accident in 4 cases. The fractures were rated as type Ⅰ in 2 cases, type Ⅱ in 9 cases, and type Ⅲ in 5 cases according to Rockwood classification criteria. The time from injury to operation ranged from 6 to 15 days, with an average of 9 days. After fracture reduction, an appropriate anatomical locking plate was selected for internal fixation. The operation time, intraoperative blood loss, and incision healing were recorded; the Lysholm score, Böstman patella fracture efficacy score, knee joint mobility, and visual analogue scale (VAS) score were used to evaluate the knee joint function and pain degree; X-ray films were used to review the fracture reduction and healing. Results The operation time was 65-100 minutes (mean, 75.3 minutes); the intraoperative blood loss was 10-35 mL (mean, 25.6 mL). All incisions healed by first intention after operation. All patients were followed up 11-26 months (mean, 19.7 months). X-ray films showed that the fractures were reduced satisfactorily, and all achieved bony healing with healing time of 3-5 months. At last follow-up, the Lysholm score was 90-95 (mean, 93.0); the Böstman patella fracture efficacy score was 27-30 (mean, 28.8), of which 12 cases were excellent and 4 were good; the VAS score was 0-1 (mean, 0.3). There was no significant difference in the range of motion of the knee joint between the healthy and affected sides [145° (140°, 150°) vs 145° (140°, 145°); Z=1.890, P=0.059]. Conclusion Choosing anatomical locking plates for Rockwood typeⅠ-Ⅲ patella fractures can achieve strong fixation with minimal surgical trauma, rapid recovery of knee joint function, and mild pain after operation.

  • A new fluoroscopic view to evaluate the medial and lateral articular reduction quality in patella fractures during internal fixation

    Objective To introduce a new fluoroscopic method for assessing the quality of medial and lateral joint surface reduction during internal fixation of patellar fractures and to summarize the clinical outcomes of patients treated using this method. Methods A retrospective analysis was conducted on the clinical data of 52 patients with patellar fractures treated between January 2018 and January 2022 who met the inclusion criteria. There were 27 male and 25 female patients, aged 21-75 years, with an average age of 62 years. The types of patellar fractures included 9 transverse fractures, 37 comminuted fractures, and 6 longitudinal fractures. According to the AO/Orthopaedic Trauma Association (AO-OTA)-2018 fracture classification, there were 21 cases of type 34A, 6 cases of type 34B, and 25 cases of type 34C. The time from injury to operation ranged from 1 to 5 days, with an average of 2.3 days. Treatments included internal fixation with hollow screws or hollow screw tension bands, with or without anchor repair. During operation, the medial and lateral joint surfaces of the patella were observed using the tangential fluoroscopic method to assess the smoothness of reduction of the median ridge, lateral joint surface, medial joint surface, and lateral joint edge. Patients were followed up regularly, and X-ray films were taken to observe fracture healing. Knee joint range of motion, Böstman score, and Lysholm score were used to evaluate functional recovery. Results The tangential fluoroscopic method for the medial and lateral joint surfaces of the patella during operation showed satisfactory reduction of the joint surfaces and good positioning of the implants. All patients were followed up 12-16 months, with an average of 13.4 months. During the follow-up, fracture displacement occurred in 1 case and titanium cable breakage in 1 case. All patella fractures healed successfully, with a healing time of 8-16 weeks (mean, 11.4 weeks). At last follow-up, knee joint range of motion ranged from 120° to 140°, with an average of 136°. The Böstman score ranged from 20 to 30, with an average of 28, yielding excellent results in 45 cases and good results in 7 cases. The Lysholm score ranged from 88 to 100, with an average of 93, yielding excellent results in 40 cases and good results in 12 cases. Conclusion The intraoperative application of the tangential fluoroscopic method for the medial and lateral joint surfaces of the patella can quickly determine the fluoroscopic plane of the patella, accurately assess the quality of fracture reduction and the position of internal fixator, thereby improving effectiveness.
