OBJECTIVE
We aimed to present the radiographic and functional outcomes of anatomical reduction and fixation of anterior inferior tibiofibular ligament (AITFL) avulsion fracture without syndesmotic screw fixation in rotational ankle fracture.
METHODS
We retrospectively reviewed 66 consecutive patients with displaced malleolar fracture combined with AITFL avulsion fracture. We performed reduction and fixation for the AITFL avulsion fracture when syndesmotic instability was present after malleolar fracture fixation. A syndesmotic screw was inserted only when residual syndesmotic instability was present even after AITFL avulsion fracture fixation. The radiographic parameters were compared with those of the contralateral uninjured ankles. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores were assessed 1 year postoperatively.
RESULTS
Fifty-four patients showed syndesmotic instability after malleolar fracture fixation and underwent reduction and fixation for AITFL avulsion fracture. Among them, 45 (83.3%) patients achieved syndesmotic stability, while 9 (16.7%) patients with residual syndesmotic instability needed additional syndesmotic screw fixation. The postoperative radiographic parameters were not significantly different from those of the uninjured ankles. The mean AOFAS score was 94.
CONCLUSION
Reduction and fixation of AITFL avulsion fracture obviated the need for syndesmotic screw fixation in more than 80% of patients with AITFL avulsion fracture and syndesmotic instability.

Avulsion injuries of the LCL most commonly occur at the fibular insertion. Femoral LCL avulsion injuries have only been previously described in pediatric patients or as multiligament knee injury components among adults. This case series with comprehensive literature review describes for the first time 2 cases of isolated LCL femoral avulsion fractures in adults including conservative treatment outcomes. Both patients sustained a strong varus stress mechanism to their right knee, following sport injury or road traffic accident. For both patients, a complete radiographic evaluation including X-rays, MRI, and CT scan confirmed no other associated knee lesions. The femoral LCL avulsion fractures that were observed were minimally displaced and noncomminuted. Furthermore, imagery suggested preserved integrity at the superior lateral genicular artery, adjacent articular capsule, and IT band. Based on clinical and imaging evaluations, the decision was made to follow conservative treatment. By 10 weeks postinjury, both patients were asymptomatic with early radiological fracture healing evidence. Comparative varus stress radiographs at 20° knee flexion revealed no side-to-side differences and clinical exam showed no posterolateral rotatory instability. The second patient case presented with mild femoral LCL attachment calcification on follow-up CT-scan. Following a detailed analysis of anatomic injury characteristics, we suggest that patients with isolated femoral LCL avulsion fractures have low secondary displacement risk provided SLGA, articular capsule, and IT band integrity are present. In contrast to high-grade ligamentous and distal avulsion LCL injuries, we recommend conservative treatment for patients who sustain these lesions.

Review
OBJECTIVE
To summarize the progress in the treatment of hyperextension tibial plateau fractures.
METHODS
Related literature concerning hyperextension tibial plateau fractures was reviewed and analyzed in terms of injury mechanisms, clinical patterns, and treatment outcomes.
RESULTS
Hyperextension tibial plateau fractures is a specific type of hyperextension knee injuries, which is happened with the knee in over-extended position (<0°) and characterized by fracture and concomitant ligament injury. It can be classified into 4 patterns: marginal avulsion fractures, unicondylar anteromedial fractures, anterolateral fractures, and bicondylar fractures. The failure of structures occurs according to the diagonal injury mechanism characterized by anterior compression fractures and posterior tension ruptures. It is noted as a rule that a smaller anterior fragment is more likely to accompany by a posterior ligament rupture. Unicondylar anteromedial fracture pattern is caused by hyperextension varus mechanism and usually accompanied by posterolateral corner rupture. Bicondylar hyperextension injury is characterized by posterior metaphyseal cortical tension rupture, anterior articular depression, and reversed posterior slope.
CONCLUSION
Currently there is no consensus on the treatment of hyperextension tibial plateau fractures. Further basic and clinical studies are needed.

Review
Background Heterotopic Ossification (HO) is a common condition referring to ectopic bone formation in soft tissues. It has two major etiologies, acquired (more common) and genetic. The acquired form is closely related to tissue trauma. The exact pathogenesis of this disease remains unclear; however, there is ongoing research in prophylactic and therapeutic treatments that is promising. Conclusions Due to HO potential to cause disability, it is so important to differentiate it from other causes in order to establish the best possible management.

Satisfactory clinical outcome of operative and non-operative treatment of avulsion fracture of the hamstring origin with treatment selection based on extent of displacement: a systematic review.
PURPOSE
To compare outcome of operative and non-operative treatment of avulsion fractures of the hamstring origin, with minor (< 1.5 cm) and major (≥ 1.5 cm) displacement, and early (≤ 4 weeks) and delayed (> 4 weeks) surgery.
METHODS
A systematic literature search was performed using PubMed, Cochrane, Embase, CINAHL and SPORTDiscus. A quality assessment was performed using the Physiotherapy Evidence Database (PEDro) scale.
RESULTS
Eight studies with 90 patients (mean age: 16 years) were included. All studies had low methodological quality (PEDro score ≤ 5). Operative treatment yielded a return to preinjury activity rate (RTPA) of 87% (95% CI: 68-95), return to sports (RTS) rate of 100% (95% CI: 82-100), Harris hip score (HHS) of 99 (range 96-100) and a University of California Los Angeles activity scale (UCLA) score of 100%. Non-operative treatment yielded a RTPA rate of 100% (95% CI:68-100), RTS rate of 86% (95% CI: 69-94), HHS score of 99 (range 96-100), and non-union rate of 18% (95% CI: 9-34). All patients with minor displacement were treated non-operatively (RTPA: 100% [95% CI: 21-100], RTS: 100% [95% CI: 51-100]). For major displacement, operative treatment led to RTPA and RTS rates of 86% (95% CI: 65-95) and 100% (95% CI: 84-100), and 0% (0/1, 95% CI: 0-79) and 100% (95% CI: 51-100) for non-operative treatment. Early surgery yielded RTPA and RTS rates of 100% (95% CI: 34-100 & 57-100) compared to 100 (95% CI: 72-100) and 90% (95% CI: 60-98) for delayed repair.
CONCLUSION
All included studies have high risk of bias. There is only low level of evidence with a limited number of included patients to compare outcome of operative and non-operative treatment. Overall outcome was satisfactory. There is a treatment selection phenomenon based on displacement, with acceptable outcome in both groups. There is insufficient data to draw conclusions regarding timing of surgery.

The degree of fracture reduction does not compromise the clinical efficacy of arthroscopic reduction and fixation of tibial posterior cruciate ligament avulsion fractures: A retrospective study.
This study aimed to explore the postoperative outcomes of patients who underwent arthroscopic internal fixation with repositioning sutures for the treatment of posterior cruciate ligament (PCL) avulsion fractures with poorly reduced fracture fragments. It was hypothesized that improperly repositioned fracture fragments might not influence the postoperative clinical outcomes in patients with PCL avulsion fractures treated by arthroscopic sutures. From January 2020 to December 2021, patients admitted to our hospital with PCL avulsion fractures were evaluated. Our inclusion criteria were as follows: diagnosis of PCL avulsion fracture as Meyers & McKeever Type II or Type III; underwent arthroscopic double tunnel suture fixation; and age below 70. Of the patients meeting these criteria, data from 34 individuals were collected by a designated follow-up officer. Based on postoperative imaging, the patients were divided into 2 groups: well fracture reduction and poor fracture reduction groups. Prior to the surgery, the Lysholm score, knee mobility, and international knee documentation committee (IKDC score) were recorded for both groups. At the 3-month post-surgery mark, CT-3D reconstruction was performed. Statistical analysis was conducted on the collected data. For data that conformed to a normal distribution, the t test was applied. For data that didn't conform, we used a non-parametric test. Both groups achieved successful wound healing without encountering any adverse events, such as fracture nonunion infection. Fracture healing was observed in both groups at the 3-month postoperative mark. The average follow-up duration was 13.24 ± 6.18 months. There were no significant differences in Lysholm score, IKDC score, or knee mobility between the well- and poorly-reduced groups at the final follow-up (P > .05). Postoperatively, both groups demonstrated significant improvements in knee function compared to the preoperative scores, with statistically significant differences observed in Lysholm score, IKDC score, and knee mobility (P < .05). Arthroscopic fixation with double-tunnel sutures proved to be a highly effective treatment approach for PCL avulsion fractures, even in cases where the fractures were poorly reduced. Remarkably, there were no significant differences observed in postoperative knee function between the well- and poorly-reduced groups, indicating that both groups achieved favorable outcomes.

BACKGROUND
Ankle fractures are among the most common injuries encountered by orthopedic surgeons, with an incidence ranging from 71 to 187 per 100 000 people. Few studies have reliably investigated injuries involving isolated fractures of the distal fibula below the level of the ankle syndesmosis. Therefore, this study details on the patient-reported outcomes of nonoperatively managed isolated infrasyndesmotic fibula (ISF) fractures with a minimum 3-year follow-up.
METHODS
A retrospective population-based cohort study was undertaken across all emergency departments serving a major urban population. Among 159 consecutive patients meeting inclusion criteria, 108 agreed to participate. Clinical information, functional outcomes, and radiographic measurements were collected from electronic medical records and 3 validated outcome measures: the American Academy of Orthopaedic Surgeons (AAOS) Foot & Ankle Scale (FAS), the AAOS Shoe-Comfort Scale (SCS), and a general questionnaire.
RESULTS
An incidence of 22 ISF fractures per 100 000 people/year was found with FAS (91.2 ± 12.9) and SCS scores (76.8 ± 27.7), similar to reported population norms. Approximately 40% of patients (n = 43) reported continuing symptoms including pain (81.8%), stiffness (68.1%), and/or instability (39.0%). Less than 13% (n = 14) reported "severe" disabilities, and no patients required operative intervention within the follow-up period. Less-favorable outcomes were reported among work-related injuries, female patients, and "avulsion-type" fractures less than 10 mm in height ( < .01). No relationships were identified between age, degree of articular-incongruity, fracture-displacement, and self-reported outcomes.
CONCLUSIONS
The majority of patients with nonoperatively managed ISF fractures reported good-to-excellent early functional outcomes. Less-favorable outcomes were reported among work-related injuries, female patients, and "avulsion-type" fractures.

Hoffa fracture combined with tibial shaft fracture and multiple ligament avulsion injuries is extremely rare. Herein, we report a case of medial Hoffa fracture with associated fracture of tibial shaft and avulsion fractures of multiple ligaments secondary to knee dislocation. A 17-year-old female with history of a motorcycle accident was referred to our hospital after knee joint reduction at a regional trauma center. Preoperative radiology revealed a medial Hoffa fracture associated with tibial shaft fracture, inferior pole patellar fracture, fibular head fracture and multiple ligament avulsion fractures including anterior cruciate ligament, posterior cruciate ligament and medial collateral ligament. A less invasive approach via arthroscopy-assisted technique and minimally invasive plate osteosynthesis (MIPO) technique was used for fracture reduction and fixation. Six months postoperatively, the patient had arthrofibrosis and adhesiolysis under arthroscopy was performed. At the last follow-up of 24 months, the patient regained knee full range of motion and returned to pre-injury level of activities. Although minimally invasive techniques were used to speed recovery, the orthopaedic surgeon should still be aware of the possibility of postoperative arthrofibrosis as multiple site fractures may need longer immobilization.

Clinical outcomes of acute displaced posterior cruciate ligament tibial avulsion fracture: A retrospective comparative study between the arthroscopic suture and EndoButton fixation techniques.
BACKGROUND
Tibial avulsion fracture of the posterior cruciate ligament is not rare in the clinic. Arthroscopic treatment is increasingly accepted, but the choice of fixation has been debated. This study aims to compare the clinical outcomes of suture and EndoButton fixation under arthroscopy for acute displaced posterior cruciate ligament avulsion fractures.
METHODS
A total 68 of 83 PCL tibial avulsion fracture cases from 2009 to 2016 were retrospectively reviewed. Some patients received arthroscopic suture initially, and later the others received arthroscopic EndoButton fixation. Associated lesions were treated if present. The Lysholm and International Knee Documentation Committee (IKDC) scores, KT-1000 arthrometry and plain radiography were evaluated at follow-up. The assessment data at two years of follow-up were used for comparing the two different fixation groups.
RESULTS
The follow-up time of 63 patients was more than 2 years. In total, 32 of the 63 patients were in the suture group, and 31 were in the EndoButton group. At two years of follow-up, knee function according to the Lysholm score was a mean of 92.5 with a 95% confidence interval [CI] of 89.45 to 96.40 in the suture group and a mean of 93.5 with a 95% CI of 90.52 to 97.28 in the EndoButton group (P=.785). More than 90% of patients in both groups rated their knee function as normal or nearly normal on IKDC subjective evaluation. KT-1000 arthrometry showed that there was no difference between the two groups, with 0 to 3mm of laxity in 91% of the cases in the suture group versus 90% of cases in the EndoButton group. All patients achieved bony healing within 3 months. No significant complications were noted in the study.
CONCLUSIONS
Both the arthroscopic suture and EndoButton fixation methods for acute displaced posterior cruciate ligament avulsion fractures resulted in comparably good clinical outcomes, radiologic healing, and stable knees at mid-term follow-up.

Review
INTRODUCTION
Tibial eminentia avulsion fracture is the paediatric equivalent to a midsubstance anterior cruciate ligament injury. It is most common between the ages of 8 and 19 years of age. The incidence is three per 100,000 per year. We explored the clinical evaluation and classification of the fracture, indications for and methods of surgery and the possible sequelae.
METHODS
We performed a systematic search in the PubMed database and retrieved 127 articles. A total of 16 articles met the defined inclusion criteria and were reviewed. Only studies on adolescents were included.
RESULTS
No prospective studies were found. The Meyers & McKeever and Zaricznyj classifications were commonly used, also when evaluating fractures for surgery. X-ray in three views is often sufficient to establish a diagnosis, but computed topographies can be necessary to further evaluate the type of fracture. There is disagreement as to whether a type II-fracture needs surgery. The method of fixation varies greatly between different kinds of suture techniques and screw fixations, but arthroscopic surgery is preferred in the most recent literature. Whether to cross the physis when fixating the fracture is also a matter of dis-agreement, but there is a lack of literature on the subject. All authors describe low rates of subjective sequelae.
CONCLUSION
Arthroscopic surgery is less invasive and allows for earlier mobilisation than other techniques. Pull-out suture seems to be a recommendable technique. There is a lack of literature on transphyseal fixation and a need for prospective studies evaluating the many different surgical techniques described and the indications for surgery.
