Purpose: The objective of this study was to investigate the effect of proximal fibular and/or posterolateral joint facet (PJF) fractures on early functional recovery after Schatzker type VI tibial plateau fractures (TPFs)., Methods: Seventy-nine patients with Schatzker type VI TPFs sustained from November 2016 to February 2021 were divided into three groups according to the integrity of the proximal fibula and PJF (groups A, B, and C). Details including demographics, duration of surgery, and complications were recorded. The Western Ontario and McMaster Universities Osteoarthritis index (WOMAC) score, Hospital for Special Surgery (HSS) score, lateral knee pain and lateral hamstring tightness were ascertained at the final follow-up. The HSS and WOMAC scores have high reliability in evaluating knee function and osteoarthritis., Results: There was a significant difference in the HSS score between groups A and C (P < 0.001) and between groups B and C (P = 0.036). The hospital stay was significantly different between groups A and C (P = 0.038) and between groups B and C (P = 0.013). There was a significant difference in lateral knee pain and lateral hamstring tightness between groups A and C (P < 0.001) and between groups B and C (P < 0.001)., Conclusion: Our study demonstrates that proximal fibular and PJF fractures do not increase the time from injury to surgery, the incidence of complications, or the duration of surgery for Schatzker type VI TPFs. However, fractures of the proximal fibula significantly increase the hospital stay, reduce knee function, and cause lateral knee pain and lateral hamstring tightness. Combined proximal fibular fracture is more decisive than PJF involvement for prognosis., (© 2023. The Author(s).)

Purpose: To evaluate the clinical efficacy of a minimally invasive arthroscopic approach and to compare it with the traditional inverted "L" approach for the treatment of posterior cruciate ligament (PCL) avulsion fractures., Methods: From January 2016 to January 2020, the clinical data from patients with PCL avulsion fracture of the tibial insertion were analyzed retrospectively. They were divided into two groups based on surgical approaches: minimally invasive approach group ( n = 15) and traditional inverted "L" group ( n = 15 cases). The operation time, incision length, intraoperative blood loss, hospitalization time and complications were all recorded and compared between the two groups. The fracture healing time, knee range of motion (ROM), and residual relaxation degree were compared between the two groups after regular follow-up. The International Knee Documentation Committee (IKDC) and Lysholm scores were used to assess knee joint function., Results: There were no significant differences between the two groups in terms of gender, age, side, body mass index, cause of injury, Meyers McKeever classification and time from injury to operation ( P > 0.05). The incision length and intraoperative bleeding in the minimally invasive group were significantly lower ( P < 0.05) than those in the traditional group. There were no significant differences between the two groups in terms of operative time, fracture healing time, or residual relaxation ( P > 0.05). The Lachman test and posterior drawer test were both negative, and there were no postoperative complications. The VAS pain score within 2 weeks and ROM within 4 weeks in the minimally invasive group were significantly better ( P < 0.05) than those in the traditional inverted "L" approach group. The knee joint stability of both groups was good 12 months after surgery, and there were no significant differences in IKDC score, Lysholm score and ROM ( P > 0.05) between the two groups., Conclusion: The minimally invasive approaches for the treatment of PCL avulsion fractures provide adequate exposure without the surgical complications associated with traditional open surgical approaches. The procedure is safe, fast and minimally invasive, and does not need a long learning curve., Competing Interests: Dr. Liang Gao is a member of the Peer J Academic Board.

Objective To compare the efficacy of triangular anchor reduction forceps and towel forceps in the treatment of long oblique or spiral distal tibial fractures. Methods The data of 58 patients admitted to the Department of Traumatic Orthopaedics in Second Affiliated Hospital of Anhui Medical University from June 2019 to March 2021 were analyzed prospectively. According to the reduction methods during operation, they were divided into point reduction forceps group (n = 26) and triangle anchor reduction forceps group (n = 32) . The operation time, intraoperative fluoroscopy times, intraoperative blood loss, postoperative fracture reduction quality, hospital stay, fracture healing time, American orthopedic foot and ankle society (AOFAS) score, curative effect and complications at the last follow-up were compared between the two groups. Results All patients participated in the follow-up for more than one year. There was no significant difference in age, sex, basic diseases and injury mechanism between the two groups. The operation time and fluoroscopy times of patients in triangle anchor reduction group were significantly lower than those in point reduction forceps group (P < 0.05), while the quality of fracture reduction was higher than that in point reduction forceps group (P < 0.05), and there was no significant difference in other perioperative indexes. The fracture healing time of patients in triangle anchor reduction group was shorter, and the ankle joint function was better than that in point reduction forceps group (P < 0.05) . There was no significant difference in the incidence of various complications between the two groups, but the overall incidence of complications in the triangle anchor reduction group was significantly lower (P < 0.05) . Conclusion Triangular anchor reduction forceps can improve the quality of fracture reduction, shorten the healing time of fracture, reduce the occurrence of complications, reduce the operation time and the number of fluoroscopy during operation, and there is no obvious increase in local infection. It is an effective and reliable reduction method. [ABSTRACT FROM AUTHOR]
