Background This study aims to explore if the arthroscopically assisted reduction and internal fixation (ARIF) technique is superior to the traditional open reduction and internal fixation (ORIF) technique in the treatment of tibial lateral plateau fractures. Methods Forty patients with tibial plateau fractures (Schatzker type I–III) treated with ARIF or ORIF from 2012 to 2017 were included in this retrospective study. All patients received pre-operative radiographs and CT scans. The patients were divided into two groups (ARIF or ORIF). All patients had a minimum follow-up of 12 months and an average follow-up of 44.4 months. The clinical and radiographic outcomes were evaluated according to the Knee Society Score (KSS) and the modified Rasmussen radiological score. Results Satisfactory clinical and radiological results were found in 39 out of 40 (97.5%) patients. KSS and modified Rasmussen radiological score were significantly better in ARIF group. The mean KSS was 92.37 (± 6.3) for the ARIF group and 86.29 (± 11.54) for the ORIF group ( p < 0.05). The mean modified Rasmussen radiographic score was 8.42 (± 2.24) for the ARIF group and 7.33 (± 1.83) for the ORIF group ( p = 0.104). Worst clinical and radiological results were related to concomitant intra-articular lesions ( p < 0.05). Meniscal tears were found and treated in 17 out of 40 (42.5%) patients. The overall complication rate was 10%. Conclusions Both ARIF and ORIF provided a satisfactory outcome for the treatment of Schatzker I–III tibial plateau fractures. However, ARIF led to better clinical results than ORIF. No statistically significant differences were found in perioperative complications, radiological results, and post-traumatic knee osteoarthritis. Level of evidence Level III
Background: To evaluate the anatomic integrity of rotator cuff repair performed by medialized single row and augmented by a porcine dermal patch, in comparison with a nonaugmented group. Methods: We conducted a single-center, prospective, double-blinded, randomized controlled trial. The sample size was predefined, and patients were divided into a study group and a control group, assessed preoperatively and at 1, 3, 6, 12, and 24 months. The EuroQol-visual analog scale; Constant-Murley questionnaire; Disabilities of the Arm, Shoulder and Hand Score; and Simple Shoulder Test were administered. The humeral-acromial distance was calculated on radiographs. Tendon thickness, tear extension, and tendon signal intensity were all measured on magnetic resonance images (MRIs) along with an evaluation of footprint extension and a classification into one of 4 healing gradesdhealed, thinned, partially healed, not healed. Results: The study population consisted of 92 patients who were equally randomized into 2 homogenous groups. Sixty-nine patients completed the 24-month follow-up. The study group showed a healing rate of 97.6% compared with 59.5% for the standard repair group. The study group showed better results in terms of repaired tendon thickness and footprint coverage, with a P value < .05, although the tendon density was comparable. The study group showed better strength recovery and functionality with the outcome scores submitted. During the entire study, only 2 patients reported complications, calling for a biopsy during revision surgery. Conclusions: Rotator cuff repairs augmented with a porcine dermal patch resulted in excellent clinical outcomes with a higher healing rate and close-to-normal MRI findings. The technique is safe and effective; in addition, it is reproducible and allows for better outcomes compared with those of standard medialized single-row repairs. This study was approved by the Comitato Etico della Provincia di Verona (study no. 394 CEP).
