Review
BACKGROUND
There is no consensus regarding the management of posterior cruciate ligament (PCL) avulsion fractures and the expected outcomes after treatment.
PURPOSE
To systematically review clinical outcomes and complications after management of tibial-sided avulsion fractures of the PCL.
STUDY DESIGN
Systematic review; Level of evidence, 4.
METHODS
A literature search of Scopus, PubMed, Medline, and the Cochrane Central Register for Controlled Trials was performed in accordance with the 2020 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Included were studies with evidence levels 1 to 4 that reported clinical outcomes after treatment of PCL tibial-sided avulsion fractures in humans. The quality of the included studies was performed using the Methodological Index for Non-Randomized Studies (MINORS) criteria. A meta-analysis was performed for patient-reported outcome measures using random-effects modeling with 95% CIs.
RESULTS
A total of 58 studies published between 1999 and 2022 were identified. The mean MINORS score was 9.90 ± 4.12, indicating overall low-quality evidence with high risk of bias. The studies comprised 1440 patients (mean age, 32.59 ± 5.69 years; 75.2% males) with a mean follow-up of 26.9 ± 19.6 months (range, 5.3-126 months). Most patients were treated with open surgery (63.6%), followed by arthroscopic surgery (29.7%) and nonoperative treatment (6.7%). All patients reported significant posttreatment improvement in both subjective and objective outcomes ( < .05 for all). Arthroscopic surgery was associated with lower postoperative posterior tibial translation compared with open surgery (range, 0.6-3.2 vs 1.7-3.1 mm), greater preoperative to postoperative improvement in Lysholm score (54.6 vs 48.8; < .0001), higher postoperative Tegner score (6.64 ± 1.03 vs 6.14 ± 2.29; = .0448), and a higher rate of return to sport (100% vs 89.5%; = .009). Nonoperative management was associated with a significantly lower fracture union rate (87% vs 99.1%; < .0001) and greater postoperative side-to-side posterior translation (4.9 ± 4.3 mm) when compared with operative management.
CONCLUSION
Although nonoperative and surgical management of PCL tibial avulsion fractures resulted in high rates of fracture union and improvement in functional outcome scores and a low incidence of complications, nonoperative treatment yielded a high side-to-side posterior displacement (>4 mm) with a lower rate of fracture union compared to surgical treatment.

Meta-Analysis
BACKGROUND
The fifth metatarsal base avulsion fracture (i.e., Pseudo-Jones fracture) is one of the most common foot fractures. The management of pseudo-Jones fractures could be carried out surgically or conservatively. This systematic review and meta-analysis aimed to provide an update about the efficacy of orthotic removable support compared to short-leg casting for individuals with pseudo-Jones fracture.
METHODS
We searched Embase, Medline, and Cochrane Central register of Controlled Trials (CENTRAL) for randomized controlled trials (RCTs) that compared the clinical outcomes of orthotic removable support and short-leg cast for adult individuals with a fifth metatarsal base avulsion fracture. We used 95% as a confidence level and P <0.05 as a threshold. The standardized mean difference (SMD) was used for the continuous outcomes, and the risk ratio (RR) was used for the dichotomous outcomes.
RESULTS
A total of 6 RCTs incorporating 403 individuals out were deemed eligible. There was no significant difference between orthotic removable support and short-leg casting regarding AOFAS score (standardized mean difference (SMD)= 0.31, 95% CI -0.17 to 0.8), pain on VAS score (SMD= -0.08, 95% CI -0.39 to 0.22), VAS-FA score (SMD= 0.22, 95% CI -0.19 to 0.62) EQ-5D VAS score, and non-union rate (RR=0.37, 95% CI 0.05 to 2.74).
CONCLUSION
The current meta-analysis reveals that there is no difference between orthotic removable support and short-leg casting for the conservative management of individuals sustaining pseudo-Jones fracture.

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.

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.

Review
PURPOSE
To develop evidence-based recommendations for the diagnosis and treatment of skeletally immature patients with subscapularis and lesser tuberosity avulsion injuries.
METHODS
We searched the online databases PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Cochrane Database of Systematic Reviews (CDSR) for relevant publications on subscapularis and lesser tuberosity injuries in skeletally immature patients. All publication dates and languages were included. From studies identified, data were extracted to identify patient characteristics, history and physical examination findings, time to diagnosis, results from imaging studies, and treatment outcomes. These findings were combined and descriptively analyzed.
RESULTS
We identified 32 publications on 60 patients with a mean age of 13.5 ± 1.7 years. The most common physical examination finding at the time of diagnosis was anterior shoulder pain, followed by subscapularis muscle weakness. The sensitivity of imaging was 16% for radiographs and 95% for magnetic resonance imaging. The median time to diagnosis was 2 months (interquartile range, 1 to 7 months). Of 60 patients, 10 (17%) underwent successful nonoperative treatment. Fifty patients (83%) underwent surgical repair, without differences in clinical outcomes after open versus arthroscopic repair. Five cases (8%) were identified where delayed treatment was associated with suboptimal outcomes and ongoing shoulder pain.
CONCLUSIONS
Subscapularis and lesser tuberosity avulsion injuries in skeletally immature patients are most commonly seen in male patients during early adolescence. A high index of suspicion should be maintained in patients with anterior shoulder pain and subscapularis muscle weakness, especially after a fall on an outstretched arm or an eccentric external rotation injury. Magnetic resonance imaging should be considered early, even if radiographic findings are negative. Both open and arthroscopic repairs are effective in restoring function, if fixation respects the soft bone of the lesser tuberosity.

Review
INTRODUCTION
Neglected tibial eminence avulsion fractures of the anterior cruciate ligament (ACL) are uncommonly seen in modern times, but are fairly common due to a missed diagnosis/mismanagement in developing countries.
OBJECTIVES
To determine the outcomes after open reduction and internal fixation of late presenting ACL avulsion fractures, and to review the literature for similar cases, in an attempt to evaluate the ideal surgical management in this unique scenario.
STUDY DESIGN
Retrospective observational study and systematic review MATERIALS: The study included 10 male and 2 female cases (mean age 29.9 years). Patients were assessed for the pre-operative knee range-of-motion (ROM), flexion deformity and stability; functional assessment was conducted using the Lysholm scale, both pre and post-operatively. Open reduction and internal fixation with two partially threaded screws (via a mini anterior approach) was performed in all 12 cases. All patients were clinically followed up for a minimum duration of 12 months. We searched PubMed, Embase and Cochrane databases from the period of inception to January 15, 2017 for similar case series/reports involving management of chronic/neglected ACL avulsion fractures and systematically reviewed these studies following standard PRISMA guidelines.
RESULTS
The median duration of presentation after injury was 12 months (range 3 to 312 months; mean 45.3 months). The mean follow-up duration was 24.1 months (range 12-48 months). All patients achieved normal knee extension except one patient who had a residual 5° flexion contracture. On physical examination, Lachman and pivot-shift tests were negative in all but 1 patient. No case required ACL reconstruction, and the fractures united radiologically within 12 weeks; all patients regained former activity levels.
DISCUSSION
Eleven published studies, mainly case reports, reported on the management of chronic/neglected ACL avulsion fractures. Arthroscopic suture/wire fixation, arthroscopic debridement of avulsed fragment and open reduction, internal fixation (ORIF) with screws are the described techniques for this uncommon entity. However, anatomic reduction of ACL avulsion fractures is difficult arthroscopically as crater depth assessment and repositioning of the avulsed fragment become a problem; the avulsed fragment may also hypertrophy, and some contractures in ACL may develop. A mini-open procedure does not add to the morbidity, overcomes reduction obstacles and allows easy fixation with screws, and can be done even in centers that do not have arthroscopic experience. The key point is accurate reduction and rigid fixation, ensuring no impingement on full extension CONCLUSIONS: Mini-open fixation allows accurate, anatomic reduction and stable fixation with screws, and should be the preferred method of fixation for late presenting ACL avulsion fractures; embedding the fragment deep into the crater or size reduction are key to preventing extension deficits.

PURPOSE
The ideal surgical management for tibial eminence avulsion fractures remains controversial with varying approach, methods of fixation and post-operative regimes reported throughout literature. The current systematic review and meta-analysis aims to compare between the different approaches, methods of fixation and post-operative regimes for tibial eminence fractures.
METHODS
The systematic review was conducted according to PRISMA guidelines. A search was conducted using PubMed, MEDLINE and CINAHL databases. The keywords used were "anterior cruciate ligament", "tibial spine" or "tibial eminence" and "fracture" or "avulsion". All original human studies that reported the surgical outcomes of tibial eminence fractures were included. Individual patient data meta-analysis was performed.
RESULTS
48 studies with 1367 patients were included. Arthroscopic fixation resulted in significantly greater stability in terms of anterior drawer test (p = 0.018) and Lachman's test (p = 0.042), as compared to open fixation, though there was no significant difference for pivot shift test. There was no significant difference identified in functional scores and activity, including Lysholm score, IKDC subjective score, Tegner score and return to sports. Suture fixation had significantly increased stability compared to screw fixation, in terms of anterior drawer test (p = 0.001) and Lachman's test (p = 0.001), though no significant difference was identified for pivot shift test. Significantly better subjective scores and return to activity were also noted for suture fixation, in terms of Lysholm score (p = 0.008), IKDC subjective score (p = 0.001) and Tegner score (p = 0.001), though no significant difference was identified for return to sports.
CONCLUSION
Arthroscopic and suture fixation had significantly superior outcomes when compared to open and screw fixation. Arthroscopic fixation resulted in significantly improved stability of the knee as compared to open fixation, though no significant difference was identified in terms of functional knee scores and return to activity. Suture fixation resulted in significantly improved stability of the knee and functional knee screws as compared to screw fixation.

The purpose of the current investigation was to synthesize the epidemiology, cause, management, and return to sport (RTS) outcomes of ilium avulsion fractures sustained during sporting activities in young athletes. Studies reporting on athletes <18 years old sustaining an avulsion fracture along the ilium [injury to the anterior superior or inferior iliac spine (ASIS or AIIS), or the iliac crest (IC)], and the athlete's RTS status were included. RTS was analyzed by injury acuity, location, mechanism of injury, and management, whereas complications were recorded. Seventy studies comprising 286 avulsions (169 ASIS, 87 AIIS, and 30 IC) were included. The mean age of athletes was 14.5 + 1.3 years (range, 8-18 years). Sprinting (n = 103/286; 36.0%) and soccer (n = 97/286; 33.9%) were the most common sports during which injuries occurred. A total of 96.5% (n = 276/286) of athletes reported successful RTS at an average of 16.2 + 19.3 weeks. The RTS rate for patients sustaining ASIS, AIIS, and IC avulsions was 95.3, 97.7, and 100%, respectively. Acute trauma was responsible for 89.8% (n = 158/176) of injuries, which demonstrated a significantly faster (13.3 + 9.3 weeks) and higher RTS rate (99.4%) compared with those with chronic avulsions (74.4 + 40.9 weeks and 83.3%, respectively). Those with complications (18.2%) had a significantly lower RTS rate (90.4%) and longer recovery (23.7 weeks) compared with athletes without complications (97.9% and 14.5 weeks, respectively). Outcomes were not significantly different based on sex or management. However, chronic avulsions and postoperative complications sustained worse RTS results. An accurate and timely diagnosis is crucial when presented with these rare injuries to avoid increasing the chronicity of injury.

Functional Outcomes and Subsequent Surgical Procedures After Arthroscopic Suture Versus Screw Fixation for ACL Tibial Avulsion Fractures: A Systematic Review and Meta-analysis.
BACKGROUND
Although arthroscopic screw fixation and suture fixation are mainstream interventions for displaced anterior cruciate ligament avulsion fractures of the tibia, the differences in clinical outcomes between them remain inconclusive.
PURPOSE
To conduct a meta-analysis comparing the clinical and functional outcomes between arthroscopic screw fixation and suture fixation for tibial avulsion fractures.
STUDY DESIGN
Systematic review; Level of evidence, 3.
METHODS
A systematic review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and using the PubMed, Embase, and Cochrane Central Register of Controlled Trials databases. Inclusion criteria were English-language articles that compared functional outcomes after screw fixation versus suture fixation for tibial avulsion fractures and had at least 1-year follow-up. Relevant data were extracted and analyzed statistically using the Mantel-Haenszel method and variance-weighted means. Random-effects models were used to generate pooled relative risk (RR) estimates with confidence intervals (CIs).
RESULTS
Of 1395 articles initially identified, we included 5 studies with 184 patients (91 patients with screw fixations and 93 patients with suture fixations). The pooled results indicated similar postoperative outcomes for screw fixation and suture fixation: Lysholm score (mean difference [MD], -0.32 [95% CI, -6.08 to 5.44]; = .91), proportion of International Knee Documentation Committee score grade A (74% vs 74%; RR, 0.63 [95% CI, 0.10-3.95]; = .63), Tegner score (MD, 0.10 [95% CI: -1.73 to 1.92]; = .92), and Lachman test results (stable knee joint, 82% vs 82%; RR, 0.99; 95% CI: 0.85-1.16; = .90). Patients in the screw fixation group had a significantly higher overall subsequent surgery rate (46% vs 19%; RR, 2.33; 95% CI,1.51-3.60; = .0001) and implant removal rate (44% vs 3%; RR, 8.52; 95% CI, 3.58-20.29; < .00001) compared with those in the suture fixation group. Nonimplant-related subsequent surgery rates were similar for the 2 groups.
CONCLUSION
The findings indicated a higher risk of subsequent surgery (RR, 2.33) and implant removal (RR, 8.52) after screw fixation when compared with suture fixation for tibial avulsion fractures. However, there were no significant differences in clinical outcome scores between the 2 techniques.

Review
PURPOSE
The purpose of this study was to systematically review case reports and case series about meniscal ossicle, to summarize existing evidence. Specifically, to identify the etiology, demographic characteristics, localization, clinical features, diagnostic procedures and treatment options of this rare entity. Although, case reports/ series are of low level of evidence, a systematic review of such studies can provide and help us to gain a better understanding and awareness of meniscal ossicle.
METHODS
Two authors searched three online databases (MEDLINE, SCOPUS and GOOGLE SCHOLAR) from inception until March 2020 for the literature on meniscal ossicle. Inclusion criteria included case series, case reports and case-based reviews, available in full-text version, in English and that concern humans. Reports published in languages other than English were excluded, as well as articles with no electronic full text availability. Case reports using the term "meniscal ossicle" to describe an acute avulsion fracture of the tibial root of the meniscus, were also excluded.
RESULTS
Of 453 initial studies, 38 studies satisfied inclusion criteria. In total 169 patients were included of whom 107 (63%) were males and 62 (37%) were females. Mean age was 44 years (range 12-87). According to Magnetic resonance imaging findings, in 144 knees (86%) the ossicle was localized at the posterior root or horn of the medial meniscus. 60% of the patients had a history of trauma. The predominant symptom in 87% of patients was knee pain. In all patients was detected an intra-articular density structure in computed radiography. 76% had associated meniscal tear, 61% had intraarticular cartilage loss, 34% meniscal extrusion and 28% anterior cruciate ligament injury. Treatment modalities included conservative regimen in 40 patients, while 59 patients underwent surgical excision.
CONCLUSION
The most possible etiology of meniscal ossicle is posttraumatic heterotopic ossification and small occult bony avulsion fracture. It is commonly observed in individuals complaining about knee pain with history of antecedent trauma. The presence of a meniscal ossicle should alert the physician to the high likelihood of the patient having an associated meniscal tear, articular cartilage loss, ACL injury or meniscal extrusion. Along with the meniscal ossicle, the associated meniscal tear should be treated as well.
