AbstractPatellar fractures account for approximately 1% of all skeletal fractures. These fractures are rare; however, because of the crucial function of the patella in the extensor mechanism of the knee, they may lead to serious impairment. New data are revealing functional impairment remains common even with improved surgical techniques. The aim of this study was to assess the functional outcomes of patients after revision surgery in cases of secondary fracture dislocation or persistent articular incongruity. This study included 16 patients with a mean age of 51.8 years (range: 16–85 years) with a mean follow-up of 35.1 months. According to the AO/OTA classification, 15 patients had a C-type fracture, including 10 patients with C3 fracture. Thirteen patients were initially treated with tension band wiring via K-wires or cannulated screws. Revision surgery was performed because of persistent articular incongruity in five patients and secondary fracture dislocation or refracture in 11 patients. We analyzed pain (visual analog scale [0–10]), satisfaction, range of motion (ROM), Böstman's score, Lysholm's score, and knee injury and osteoarthritis outcome score (KOOS) after revision surgery and could extract follow-up data from 15 patients. Mean pain score at rest was 0.57 (range: 0–3.5) and on exertion 2.79 (range: 0–8). The measurement of the ROM of the affected knee compared with that of the opposite knee revealed complete extension. Mean flexion was 123 degrees, in the corresponding knee it was 136 degrees (p = 0.05). The mean postoperative Böstman's and Lysholm's scores were 25.11 (good, maximum: 30) and 78.67 (moderate, maximum: 100), respectively. KOOS was as follows: symptoms, 66.8 points; pain, 77.55 points; activity of daily living (ADL), 75.67 points; and quality of life, 56.25 points. The results of this study suggested that early revision surgery after failure of primary osteosynthesis with secondary anatomic reconstruction and good radiological results leads to satisfactory functional outcomes with persistent functional deficits.

Summary Objectives: To retrospectively evaluate stabilisation of long-bone fractures in cats and small dogs using the Unilock system. Methods: Medical histories and radiographs of consecutive patients with long-bone fractures stabilised with the Unilock system were reviewed. Cases with follow-up radiographs taken at least four weeks postoperatively were included. Signalment of the patient, fracture localisation and type, primary fracture repair or revision surgery, single or double plating, and complications for each patient were noted. Additionally, implant size, number of screws, number of cortices engaged with screws, and number of empty holes across the fracture were evaluated in fractures where a single plate had been applied. Results: Eighteen humeral, 18 radial, 20 fe-moral, and 10 tibial fractures were treated. The Unilock system was used for primary repair in 44 fractures and for revision surgery in 22 fractures. Two plates were applied in 17 fractures, and a single plate was applied in 49 fractures. Follow-up radiographs were taken four to 109 weeks postoperatively. Complications were seen in 12 animals and 13 fractures (19.7%). Fixation failure occurred in seven fractures (10.6%). Cases with a single plate that suffered fixation failure had thinner screws in relation to bone diameter than cases with double plates, and more screws in a main fragment than those without fixation failure. Clinical significance: The Unilock system is a suitable implant for fracture fixation of long bones in cats and small dogs.

Abstract Background Volar marginal rim distal radius fractures can be challenging due to volar instability of the carpus. The associated carpal injuries, however, have not previously been reported. Purpose The aim of this study was to compare volar marginal rim fractures to other distal radius fractures to determine if there is any association with other carpal injuries. If so, do these injuries lead to further instability and fixation failure? Materials and Methods A retrospective radiological review of 25 volar marginal rim fractures was conducted. This was compared with a comparison cohort of 25 consecutive intra-articular distal radius fractures not involving the volar marginal rim. All radiographs were reviewed for associated carpal injuries, including carpal and ulnar styloid fractures, scapholunate instability, and carpal translocation. Results Volar marginal rim fractures had a significantly higher incidence of associated carpal injuries per patient (2.52 vs. 1.64), scapholunate diastasis (36 vs. 12%), and carpal dislocation (80 vs. 48%). The fixation chosen was more likely to involve a volar rim-specific plate (44 vs. 0%). Following surgical fixation, the volar marginal rim fractures had a significantly higher incidence of carpal instability (56 vs. 24%), failure of fixation (24 vs. 0%), and revision surgery (12 vs. 0%). Conclusions Volar marginal rim fractures have significantly more carpal injuries, scapholunate instability, and volar carpal instability, compared with other distal radius fractures. Despite the use of volar rim-specific plating, volar marginal rim fractures have a significantly higher incidence of persistent carpal instability, including scapholunate instability, ulnar translocation, volar subluxation, failure of fixation, and revision surgery. Level of Evidence This is a level III, retrospective review.

Background: Hip arthroscopic surgery has become an increasingly common surgical technique to diagnose and treat various hip abnormalities. While increased efficacy has been reported, debate remains regarding appropriate surgical indications. Multiple factors including patient demographics, surgical procedure, and underlying disease have been associated with poor surgical outcomes. Preoperative diagnostic and treatment interventions including physical therapy and injections may affect surgical indications and outcomes. Purpose: To identify patient characteristics and preoperative factors associated with an increased risk of early revision surgery and/or extended postoperative medical care after index hip arthroscopic surgery. Study Design: Case-control study; Level of evidence, 3. Methods: Utah’s All Payer Claims Database, a state-mandated registry containing data from all payers, including private insurance, Medicare Advantage, and Medicaid, was queried to identify patients who underwent hip arthroscopic surgery during a 3-year period (January 1, 2013, to December 31, 2015). Demographics, comorbidities, nonoperative care modalities, pain medications, and revision procedures were collected using claims data at 6 months preoperatively and 12 months postoperatively. Results: A total of 1283 patients who underwent primary hip arthroscopic surgery were analyzed, of whom 57.6% (n = 739) were female. Within 1 year of index surgery, 7.8% and 2.1% of patients underwent revision hip arthroscopic surgery and conversion to total hip arthroplasty (THA), respectively. Patients older than 60 years and male patients were more likely to undergo revision arthroscopic surgery (odds ratio [OR], 0.89; P < .001 and OR, 1.59; P = .04, respectively) and convert to THA (OR, 1.03; P = .01 and OR, 2.25; P = .05, respectively). Preoperative opioid use was significantly associated with increased odds of revision surgery (OR, 1.64; P = .05) and THA (OR, 2.70; P = .03). No significant relationship existed between preoperative physical therapy or intra-articular hip injections and revision hip arthroscopic surgery (OR, 1.20; P = .45 and OR, 1.18; P = .52, respectively) or conversion to THA (OR, 0.89; P = .79 and OR, 0.71; P = .46, respectively). Conclusion: This study showed that predictable patient factors can effectively guide preoperative decision making and may improve prognosis. Certain patient pools require optimization preoperatively, and a subset of patients appears to require additional surgical indications.
