Objective To evaluate clinical and radiological outcomes including hindfoot alignment after plate vs intramedullary nailing (IMN) for distal tibia fracture and to define radiologic parameters that influence changes in hindfoot alignment. Methods Among 92 patients with distal tibia metaphyseal fractures treated from 2002 to 2015, 39 cases of intramedullary nailing and 53 cases of standard plate osteosynthesis were performed. Union rate and complication rate were compared in both groups. Radiographic measurements including hindfoot angulation, moment arm, calcaneal pitch angle, and Meary angle were evaluated at a minimum of 1‐year follow‐up. Hindfoot alignment changes after surgery were compared between both groups using student t‐test. Correlation and regression were analyzed between fracture alignment parameters and hindfoot alignment. Results All patients ultimately healed, with an average union period of 26 weeks in both groups. The AOFAS and VAS scores were not significantly different between the two groups. Complications were similar between the two groups. Hindfoot alignment angle, calcaneal pitch, and Meary angle showed no significant differences between the groups. The hindfoot moment arm increased with valgus in the IMN group. A low correlation was detected between angulation at the fracture site in the coronal view and hindfoot alignment (angulation and moment arm) changes (R = 0.38). A significantly high correlation was noted only between transverse rotation and hindfoot alignment changes (R = 0.79). Conclusions Rotation in the transverse plane notably influenced changes in hindfoot alignment. And this suggests that patients with distal tibia fracture should be closely monitored for hindfoot alignment changes caused by intraoperative transverse rotation regardless of the fixation method. Reduction and stable fixation of distal extra‐articular tibia fractures with intramedullary nail is often technically challenging because of a large medullary cavity within a short distal fragment. This article evaluates clinical and radiological outcomes including hindfoot alignment after plate vs intramedullary nail for distal tibia fracture and to define radiologic parameters that influence changes in hindfoot alignment. In this study, 92 patients with distal tibia metaphyseal fractures treated with intramedullary nailing and standard plate osteosynthesis from 2002 to 2013 were included. Clinical and radiologic comparison were made between standard plate and intramedullary nail group. Relationship of ankle alignment changes and hindfoot alignment changes were evaluated. The result showed angulation on coronal plane after internal fixation may slightly affect hindfoot alignment due to compensation on the subtalar joint. However, rotation on the transverse plane has intimately influenced hindfoot alignment.

Purpose Tibial plateau fractures (TPFs) may lead to posttraumatic osteoarthritis and increase the risk for total knee arthroplasty (TKA). The aim of this systematic review was to analyse the conversion rate to TKA after TPF treatment. Methods A systematic search for studies reviewing the conversion rate to TKA after TPF treatment was conducted. The studies were screened and assessed by two independent observers. The conversion rate was analysed overall and for selected subgroups, including different follow-up times, treatment methods, and study sizes. Results A total of forty-two eligible studies including 52,577 patients were included in this systematic review. The overall conversion rate of treated TPF to TKA in all studies was 5.1%. Thirty-eight of the forty-two included studies indicated a conversion rate under 10%. Four studies reported a higher percentage, namely, 10.8%, 10.9%, 15.5%, and 21.9%. Risk factors for TKA following TPF treatment were female sex, age, and low surgeon and hospital volume. The conversion rate to TKA is particularly high in the first 5 years after fracture. Conclusion Based on the studies, it can be assumed that the conversion rate to TKA is approximately 5%. The risk for TKA is manageable in clinical practice.

Objective The aim of this study is to assess the prevalence of nonunion in patients with tibia fracture and the association between influencing factors and tibia fracture nonunion. Method A database searches of PubMed, the Cochrane Library, EMBASE, China National Knowledge Infrastructure (CNKI), Weipu database, and Wanfang database from inception until June 2019 was conducted. The pooled prevalence, odds ratio (OR), and 95% confidence intervals (CI) were calculated with Stata software. Results In this study, 111 studies involving 41,429 subjects were included. In the study of the relationship between influencing factors and tibia fracture nonunion, 15 factors significantly influenced the fracture union, including > 60 years old, male, tobacco smoker, body mass index > 40, diabetes, nonsteroidal anti-inflammatory drugs (NSAIDs) user, opioids user, fracture of middle and distal tibia, high-energy fracture, open fracture, Gustilo-Anderson grade IIIB or IIIC, Müller AO Classification of Fractures C, open reduction, fixation model, and infection. Conclusion The prevalence of nonunion in patients with tibia fracture was 0.068 and 15 potential factors were associated with the prevalence. Closed reduction and minimally invasive percutaneous plate osteosynthesis (MIPPO) have the low risks of nonunion for the treatment of tibial fractures.

Purpose To evaluate the prevalence of and factors associated with meniscal ramp lesions on magnetic resonance imaging (MRI) in patients with anterior cruciate ligament (ACL) injuries. Methods Data from the Natural Corollaries and Recovery after ACL injury multicentre longitudinal cohort study (NACOX) were analysed. Only patients who underwent MRI were included in this study. All MRI scans were reviewed by an orthopaedic knee surgeon and a musculoskeletal radiologist. The patients were divided into two groups, those with and without ramp lesions according to MRI findings. Univariable and stepwise forward multiple logistic regression analyses were used to evaluate patient characteristics (age, gender, body mass index, pre-injury Tegner activity level, activity at injury) and concomitant injuries on MRI (lateral meniscus, medial collateral ligament [MCL], isolated deep MCL, lateral collateral ligament, pivot-shift-type bone bruising, posteromedial tibial [PMT] bone bruising, medial femoral condyle bone bruising, lateral femoral condyle [LFC] impaction and a Segond fracture) associated with the presence of meniscal ramp lesions. Results A total of 253 patients (52.2% males) with a mean age of 25.4 ± 7.1 years were included. The overall prevalence of meniscal ramp lesions was 39.5% (100/253). Univariate analyses showed that contact sports at ACL injury, pivot-shift-type bone bruising, PMT bone bruising, LFC impaction and the presence of a Segond fracture increased the odds of having a meniscal ramp lesion. Stepwise forward multiple logistic regression analysis revealed that the presence of a meniscal ramp lesion was associated with contact sports at ACL injury [odds ratio (OR) 2.50; 95% confidence intervals (CI) 1.32–4.72; P  = 0.005], pivot-shift-type bone bruising (OR 1.29; 95% CI 1.01–1.67; P  = 0.04), PMT bone bruising (OR 4.62; 95% CI 2.61–8.19; P  < 0.001) and the presence of a Segond fracture (OR 4.38; 95% CI 1.40–13.68; P  = 0.001). Conclusion The overall prevalence of meniscal ramp lesions in patients with ACL injuries was high (39.5%). Contact sports at ACL injury, pivot-shift-type bone bruising, PMT bone bruising and the presence of a Segond fracture on MRI were associated with meniscal ramp lesions. Given their high prevalence, meniscal ramp lesions should be systematically searched for on MRI in patients with ACL injuries. Knowledge of the factors associated with meniscal ramp lesions may facilitate their diagnosis, raising surgeons’ and radiologists’ suspicion of these tears. Level of evidence III.

Purpose The impact of posterolateral tibial plateau impaction fractures (TPIF) on posttraumatic knee stability in the setting of primary anterior cruciate ligament (ACL) tear is unknown. The main objective was to determine whether increased bone loss of the posterolateral tibial plateau is associated with residual rotational instability and impaired functional outcome after ACL reconstruction. Methods A cohort was identified in a prospective enrolled study of patients suffering acute ACL injury who underwent preoperative standard radiographic diagnostics and clinical evaluation. Patients were included when scheduled for isolated single-bundle hamstring autograft ACL reconstruction. Exclusion criteria were concurrent anterolateral complex (ALC) reconstruction (anterolateral tenodesis), previous surgery or symptoms in the affected knee, partial ACL tear, multi-ligament injury with an indication for additional surgical intervention, and extensive cartilage wear. On MRI, bony (TPIF, tibial plateau, and femoral condyle morphology) and ligament status (ALC, concomitant collateral ligament, and meniscus injuries) were assessed by a musculoskeletal radiologist. Clinical evaluation consisted of KT-1000, pivot-shift, and Lachman testing, as well as Tegner activity and IKDC scores. Results Fifty-eight patients were included with a minimum follow-up of 12 months. TPIF was identified in 85% of ACL injuries ( n  = 49). The ALC was found to be injured in 31 of 58 (53.4%) cases. Pearson analysis showed a positive correlation between TPIF and the degree of concomitant ALC injury ( p  < 0.001). Multiple regression analysis revealed an increased association of high-grade TPIF with increased lateral tibial convexity ( p  = 0.010). The high-grade TPIF group showed worse postoperative Tegner scores 12 months postoperatively ( p  = 0.035). Conclusion Higher degrees of TPIFs are suggestive of a combined ACL/ALC injury. Moreover, patients with increased posterolateral tibial plateau bone loss showed lower Tegner activity scores 12 months after ACL reconstruction. Level of evidence III.

Tibial plateau fractures, accounting for approximately 1% of adult fractures, are often associated with significant long-term complications such as pain, stiffness, and posttraumatic arthrosis. The optimal treatment approach remains controversial, particularly in resource-limited settings. This study investigated the factors influencing the clinical outcomes of patients with tibial plateau fractures in Ethiopia. Tibial plateau fractures, though common in trauma cases, have been poorly studied in sub-Saharan Africa, particularly in Ethiopia. The primary purpose of this study was to examine the factors influencing the clinical outcomes of patients with tibial plateau fractures and to assess the efficacy of conservative treatment versus surgical intervention. This research aims to provide insights into managing tibial plateau fractures in resource-limited settings, with the hope of contributing to improved clinical practices. A total of 191 patients with tibial plateau fractures were recruited from Tibebe Ghion Referral Hospital and Felegehiwot Specialized Hospital between February 1, 2018, and February 2022. Demographic, clinical, and radiological data were analyzed, and treatment outcomes were assessed via Rasmussen's knee functional outcome score. A correlation analysis was performed to identify factors impacting functional outcomes. Logistic regression was used to identify factors influencing clinical outcomes. The study population was predominantly male (73.8%), with a mean age of 45 years. Road traffic accidents (41.9%) were the most common cause of injury. Schatzker type I fractures (27.2%) were the most common, and compound fractures accounted for 21% of the fractures. The average time to definitive management was 1.59 weeks, with 35% of patients undergoing open reduction and internal fixation (ORIF). The duration of immobilization and weight-bearing significantly influenced functional outcomes. Patients who were immobilized for less than 4 weeks had better outcomes, with functional scores 54 times better than those of patients who were immobilized for more than 8 weeks (p < 0.01). Early initiation of partial weight-bearing also improved outcomes. A strong negative relationship was found between the duration of immobilization and functional outcomes (r = -0.705, p < 0.01). This study highlights the importance of early mobilization and optimal management of tibial plateau fractures for improving functional outcomes. Timely treatment, especially regarding immobilization and weight-bearing, is crucial for achieving better results. These findings emphasize the need for more standardized treatment protocols and further research on tibial plateau fractures in sub-Saharan Africa to increase patient care in resource-limited settings.

IntroductionOnly few and inconsistent data about the impact of articular congruity and tolerable residual intraarticular steps and gaps of the joint surface after tibial plateau fractures exist. Therefore, aim of this study was to investigate the correlation between OTA type B and C tibial plateau fracture outcomes and postoperative articular congruity using computed tomography (CT) data.Materials and methodsFifty-five patients with a mean age of 45.5 ± 12.5 years and treated for 27 type B and 28 C tibial plateau fractures with pre- and postsurgical CT data were included. Primary outcome measure was the correlation of postoperative intraarticular step and gap sizes, articular comminution area, the postoperative medial proximal tibial angle (MPTA), and the Lysholm and IKDC score. Receiver-operating characteristic (ROC) curves were used to determine threshold values for step and gap heights according to the following outcome scores: IKDC > 70; Lysholm > 80. Secondary outcome measures were the correlation of fracture severity, the number of complications and surgical revisions and the outcome scores, as well as the Tegner activity score before injury and at final follow-up.ResultsAfter a mean follow-up of 42.4 ± 18.9 months, the mean Lysholm score was 80.7 ± 13.3, and the mean IKDC score was 62.7 ± 17.6. The median Tegner activity score was 5 before the injury and 4 at final follow-up (p < 0.05). The intraarticular step height, gap size, comminution area and MPTA deviation were significantly negatively correlated with the IKDC and Lysholm scores. The cutoff values for step height were 2.6 and 2.9 mm. The gap size threshold was 6.6 mm. In total, an average of 0.5 ± 0.8 (range 0–3) complications occurred, and on average, 0.5 ± 1.1 (range 0–7) surgical revisions had to be performed. The number of complications and surgical revisions also had negative impacts on the outcome. Neither fracture severity nor BMI or patient’s age was significantly correlated with the IKDC or Lysholm score.ConclusionsTibial plateau fractures are severe injuries, which lead to a subsequent reduced level of patient activity. Precise reconstruction of the articular surface with regard to intraarticular step and gap size, residual comminution area and joint angle is decisive for the final outcome. Complications and surgical revisions also worsen it.Level of evidenceIII.

Purpose There is growing interest in tibial tubercle fractures in pediatric and adolescent population within the last decade. However, there is limited evidence in the existing literature. Therefore, the purpose of this systematic review was to analyze and provide up-to-date data that may prove valuable in decision making and management of these injuries in the general as well as the athletic population. Methods A systematic review of the literature in PubMed, Cochrane library and Virtual Health Library was conducted using the \"Preferred Reporting Items for Systematic Reviews and Meta-Analysis\" (PRISMA) guidelines. Articles published in English or Spanish, during the past 20 years, reporting outcomes of tibial tubercle fracture management in patients younger than 18 years old, with a mean follow-up of at least 6 months reporting outcomes, type of management and classification were included. Results A total of 919 patients with 956 fractures in 25 retrospective cohort studies were included. The mean age was 14.4 ± 0.6 years while 766 [83%] were males and 740 [81%] of the injuries were sports-related. Associated injuries were reported in 91[10%] cases, most common being patellar tendon avulsion. Surgical management was chosen for 845[88%] of the cases, the vast majority being open reduction internal fixation (ORIF) with screws. Union was achieved in 954 [99.8%] cases. Complications and re-operations rate stood at 172[18%] and 161 [19% of the operations], respectively. Return to play (RTP) was reported in 11 [44%] of the studies standing at an average of 98.9% ± 3.6. Conclusion Essentially, this is an adolescent sports knee injury that needs careful planning before decision making because it may affect both RTP and joint preservation. Although union was achieved in almost all patients, there is a high risk of associated injuries, complications and reoperations. The surgeon should be confident to perform fracture fixation as well as addressing associated knee soft tissue injuries to achieve optimal outcomes. Level of evidence Level IV.

This randomized clinical trial evaluated the impact of immediate weight-bearing as tolerated on spatiotemporal gait parameters and fall risk in patients undergoing postoperative rehabilitation for tibial plateau fractures. A total of 106 patients who had undergone open reduction and internal fixation (ORIF) for Schatzker I-IV tibial plateau fractures were recruited, with 39 meeting the inclusion criteria and 10 lost to follow-up. Patients were randomly assigned to a non-weight-bearing group (NWB), following a 6-week non-weight-bearing rehabilitation protocol, or a weight-bearing group (WB), allowed immediate weight-bearing. Both groups received the same therapeutic exercise program. Gait parameters were assessed three months post-surgery, including step length, stride length, single stance time, double stance time, step time, stride time, velocity, cadence, stride width, and gait and balance scores from Tinetti Performance Oriented Mobility Assessment (POMA). Of the 29 patients who completed the study, significant differences in favor of the WB group were observed for affected limb step length (p = 0.010), sound limb step length (p = 0.013), stride length (p = 0.010), affected single limb stance time (p = 0.001), sound single limb stance time (p = 0.007), velocity (p = 0.021), and POMA scores for balance (p = 0.021) and gait (p = 0.002). Immediate weight-bearing as tolerated after ORIF for Schatzker I-IV tibial plateau fractures resulted in improved spatiotemporal gait parameters and reduced fall risk.

Purpose Although the mechanisms of injury are similar to ACL rupture in adults, publications dealing with meniscal lesions resulting from fractures of the intercondylar eminence in children are much rarer. The main objective was to measure the frequency of meniscal lesions associated with tibial eminence fractures in children. The second question was to determine whether there is any available evidence on association between meniscal tears diagnostic method, and frequencies of total lesions, total meniscal lesions, and total entrapments. Methods A comprehensive literature search was performed using PubMed and Scopus. Articles were eligible for inclusion if they reported data on intercondylar tibial fracture, or tibial spine fracture, or tibial eminence fracture, or intercondylar eminence fracture. Article selection was performed in accordance with the PRISMA guidelines. Results In total, 789 studies were identified by the literature search. At the end of the process, 26 studies were included in the final review. This systematic review identified 18.1% rate of meniscal tears and 20.1% rate of meniscal or IML entrapments during intercondylar eminence fractures. Proportion of total entrapments was significantly different between groups (17.8% in the arthroscopy group vs. 6.2% in the MRI group; p  < .0001). Also, we found 20.9% of total associated lesions in the arthroscopy group vs. 26.1% in the MRI group ( p  = .06). Conclusion Although incidence of meniscal injuries in children tibial eminence fractures is lower than that in adults ACL rupture, pediatric meniscal tears and entrapments need to be systematically searched. MRI does not appear to provide additional information about the entrapment risk if arthroscopy treatment is performed. However, pretreatment MRI provides important informations about concomitant injuries, such as meniscal tears, and should be mandatory if orthopaedic treatment is retained. MRI modalities have yet to be specified to improve the diagnosis of soft tissues entrapments. Study design Systematic review of the literature Registration PROSPERO N° CRD42021258384
