Comparison of outcome of ARIF and ORIF in the treatment of tibial plateau fractures

The efficacy of arthroscopy-assisted versus stand-alone open reduction and internal fixation for treating tibial plateau fracture: a systematic review and meta-analysis

BACKGROUND

The optimal surgical technique for treating tibial plateau fractures remains controversial. This study aimed to compare the outcomes of arthroscopy-assisted reduction and internal fixation (ARIF) to those of open reduction and internal fixation (ORIF) in treating tibial plateau fractures.

METHODS

This systematic review and meta-analysis were conducted to compare surgical outcomes between ARIF versus ORIF for patients with tibial plateau fractures. Relevant studies, comprising randomized controlled trials (RCTs) and non-RCTs, were identified through searches in Cochrane CENTRAL, PubMed, and Embase databases. Risk of bias assessments were conducted using the revised Cochrane risk-of-bias tool for RCTs (RoB 2.0), Newcastle Ottawa scales for non-RCTs, and Joanna Briggs Institute Critical Appraisal Checklist for case series studies. Data synthesis utilized a random-effects model meta-analysis. The primary outcome assessed was functional outcomes, with complications considered as secondary outcomes.

RESULTS

There were fifteen studies (one RCT and fourteen non-RCTs) included in this study, comprising a total of 969 participants (548 in the ARIF group and 421 in the ORIF group). Although patients in the ARIF group showed a trend towards better functional outcomes compared to the ORIF group, the difference was not statistically significant (Hospital for special surgery score, mean difference (MD) = 5.13, 95% confidence interval (CI)=-1.67 to 11.92, I²=83%; Knee society score, MD = 5.84, 95% CI=-1.18 to 12.86, I²=74%). No significant differences were noted in infection, stiffness, DVT, and overall complications between two groups. The ARIF group included ten case series studies with a total of 302 patients. The pooled mean Rasmussen Radiological Score was 16.59 (95% CI, 15.72 to 17.50), and the pooled mean Rasmussen Clinical Score was 27.38 (95% CI, 26.45 to 28.33).

CONCLUSION

The findings of this study reveal no significant difference in clinical outcomes and complication rates between ARIF and ORIF. Additionally, this study found that the complication rate for patients undergoing ARIF falls within previously reported ranges. This suggests that ARIF is a reliable and effective surgical option for treating tibial plateau fractures, even in cases involving high-energy trauma.

Double reverse traction repositor assisted closed reduction and internal fixation versus open reduction and internal fixation for treatment of lateral tibial plateau fractures among the elderly

BACKGROUND

In elderly tibial plateau fractures (TPFs), the lateral condyles are involved frequently. This study aimed to compare the outcomes of open reduction and internal fixation (ORIF) and double reverse traction repositor (DRTR) assisted closed reduction and internal fixation (CRIF) in elderly patients with lateral TPFs.

METHODS

From January 2015 to July 2020, we retrospectively reviewed 68 patients treated surgically at our trauma center for lateral TPFs (Schatzker type I-III). 31 patients were eventually assigned to the DRTR assisted CRIF group, whereas 37 patients were assigned to the ORIF group. The primary outcomes included surgical details, radiological assessment, follow-up knee function, and complications.

RESULTS

The DRTR assisted CRIF group experienced a 43.6 mL decrease in intraoperative blood loss (161.3 ml vs 204.9 ml, p = 0.033), and the operation duration was 32.1 min shorter than the ORIF group (83.8 min vs 115.9 min, p < 0.001). There was no statistically significant difference in terms of widening of the tibia plateau (WTP), depth of articular depression (DAD), medial proximal tibial angle (MPTA) and posterior tibial slope angle (PTSA) immediately after surgery and at the last follow-up. No differences in malreduction (p = 0.566) or reduction loss (p = 0.623) were observed between the groups, and Lysholm and HSS scores were similar between the two groups (83.6 ± 15.8 vs 83.4 ± 5.1, p = 0.934; 89.3 ± 7.8 vs 86.9 ± 6.2, p = 0.172; respectively). However, ORIF was associated with a greater increase in postoperative complications than DRTR assisted CRIF (3.2% vs 27%, p = 0.008).

CONCLUSION

Both types of internal fixation provide good radiological outcomes and knee function in the treatment of lateral TPFs in the elderly. However, DRTR assisted CRIF has the advantage of a shorter duration of surgery, less blood loss, and fewer postoperative complications, and appears to be a better treatment option for elderly patients with lateral TPFs.

Diagnostic impacts on management of soft tissue injuries associated with tibial plateau fractures: A narrative review

INTRODUCTION

Currently there is no consensus on the need for investigating knee ligamentous and meniscal injuries in a patient with a tibial plateau fracture. Consequently, many soft tissue injuries are likely undiagnosed and therefore untreated. The impact this has on long term knee outcomes is not well defined. We aimed to identify the impacts of various diagnostic methods on the management of meniscal injuries associated with tibial plateau fractures and evaluate the clinical outcomes.

MATERIALS AND METHODS

We performed a systematic review using Pubmed, Medline, Embase, CINAHL and Cochrane following Cochrane guidelines. We included studies that operatively managed tibial plateau fractures and soft tissue injuries, which were diagnosed with either preoperative MRI, intra-operative arthroscopy or arthrotomy.

RESULTS

18 articles with 884 people, with a mean age of 46.4 years were included. Soft tissue injuries were detected on MRI (32-73%) and arthroscopy (12-70%), of which the most common were lateral meniscal injuries (7-64% of tibial plateau fractures). When identified by arthroscopy and arthrotomy, these injuries were almost always treated, either by repair or debridement. The clinical outcomes of these patients were poorly reported, with a heterogenous use of patient reported outcome measures, and follow up time points. There were no randomised trials or control groups for comparative analysis, however operative treatment yielded good to excellent outcomes.

CONCLUSION

There is a high incidence of concomitant soft tissue injuries with tibial plateau fractures, particularly lateral meniscal injuries. There are 2 main approaches to meniscal injuries: surgeons who don't investigate, don't treat, whilst surgeons who do investigate often do surgically treat. Although studies that treated these injuries achieved good to excellent results, the currently available evidence doesn't confirm treatment superiority. As there is plausibility for better outcomes, randomised studies are needed to further investigate this clinical question.

The use of arthroscopy does not increase the incidence of complications in the management of Schatzker IV-VI tibial plateau fractures

BACKGROUND AND OBJECTIVE

The use of arthroscopy for tibial plateau fractures type I, II and III according to Schatzker classification has increased, yet its employment for tibial plateau fractures Schatzker IV, V and VI is controversial due to the potential risk of compartment syndrome, deep vein thrombosis and infection. We aimed to compare the rate of operative and postoperative complications among patients with these types of tibial plateau fractures treated with and without arthroscopy at the time of definitive reduction and osteosynthesis.

METHODS

Retrospective cohort study. Patients with diagnosis of tibial plateau fracture Schatzker IV, V or VI who underwent reduction and definitive osteosynthesis with or without the use of arthroscopy were included. The development of compartment syndrome, deep vein thrombosis, and fracture-related infection was evaluated up to 12 months after the definitive surgery.

RESULTS

Two hundred eighty-eight patients were included: 86 with arthroscopic assistance and 202 without it. The overall complication rate in the group with and without arthroscopic assistance was 18.60% and 26.73%, respectively (P=.141). No statistical association was found between the use of arthroscopic assistance and the development of the analyzed complications.

DISCUSSION AND CONCLUSION

The use of arthroscopy to support reduction or addressing concomitant intra-articular injuries did not increase the risk of complications in patients with high-energy tibial plateau fractures at 12 months of follow up.

Comparison of Arthroscopic-Assisted Percutaneous Internal Fixation With a Modified Reducer Versus Open Reduction and Internal Fixation for Schatzker Type II and III Tibial Plateau Fractures

Background

Tibial plateau fractures require anatomical reduction and stable fixation to achieve satisfactory results. In addition, addressing any related injuries is of paramount importance. Arthroscopic reduction and internal fixation (ARIF) has been promoted as a possible technique to treat tibial plateau fractures.

Purpose

To compare the effectiveness of ARIF with this modified reducer and open reduction and internal fixation (ORIF) for Schatzker types II and III tibial plateau fractures.

Study Design

Cohort study; Level of evidence, 3.

Methods

We retrospectively reviewed 68 patients who were treated for Schatzker type II or III tibial plateau fractures between August 1, 2014, and October 31, 2018. Patients were categorized into the ARIF (n = 33) and ORIF groups (n = 35). The groups were compared regarding intra-articular injuries, duration of hospital stay, complications, and clinical outcomes-including the International Knee Documentation Committee (IKDC) score, the Hospital for Special Surgery (HSS) score, and range of motion (ROM). The paired t test was used to compare preoperative and postoperative data, and the chi-square test was used to compare the IKDC and HSS scores.

Results

The median follow-up period was 36 months (26-40 months). Additional intra-articular lesions were found in 29 patients-21 in the ARIF group and 8 in the ORIF group (P = .02). A significant difference was observed in the duration of hospital stay-3.58 ± 1.46 days for the ARIF group and 4.57 ± 1.12 days for the ORIF group (t = -3.169; P = .002). All fractures healed within 3 months after surgery. The complication rate for all patients was 11%, with no significant difference between the ARIF and ORIF groups (t = 1.244; P = .265). At the final follow-up, there were no significant differences between the 2 groups in the IKDC score, HSS score, and ROM (P > .05 for all).

Conclusion

ARIF with a modified reducer was found to be an effective, reliable, and safe procedure for the treatment of Schatzker types II and III tibial plateau fractures. Both ARIF and ORIF provided equally good results, while ARIF offered a more precise evaluation and reduced the duration of hospital stay.

Soft tissue injury prediction using joint depression in computed tomography in AO 41B lateral tibial plateau fractures

Tibial plateau fractures are usually associated with soft tissue injury. This study aimed to use the extent of joint depression and lateral widening in computed tomography (CT) to predict the soft tissue injury accompanying fractures.The study included 23 patients with type Arbeitsgemeinschaft für Osteosynthesefragen-classified 41B fractures. Demographics, mechanism of injury, age, gender, and injury sites were assessed. Post-traumatic radiography, magnetic resonance imaging (MRI), and CT were obtained. MRI evaluated the meniscal, cruciate, and collateral ligament injuries, and CT measured the extent of joint depression and lateral widening in millimeters using digital imaging software. The relationship between joint depression, lateral widening, and soft tissue injuries was statistically analyzed. Of the 23 patients, 17 (74%) were males and 6 (26%) were females. Lateral meniscus injuries increased and the risk of bucket handle lateral meniscus tears increased as the CT joint depression exceeded 12 mm (p < 0.05). Joint depression of <5.9 mm was associated with medial meniscus injury (p < 0.05). The mean distribution examination of all soft tissue injuries and joint depression revealed no statistically significant difference between the groups (p > 0.05). Increased joint depression in lateral tibial plateau fractures increases the risk of lateral meniscus bucket handle tear, and decreased joint depression increases the risk of medial meniscus injury. Accordingly implementing the treatment plan and patient management will improve the clinical outcomes.

Current concepts review. Management of proximal tibial fractures

The management of proximal tibial fractures has evolved significantly in recent years. While the main goals of treatment - stability, restoration of the mechanical axis, and smooth articular surfaces - remain the same, methods have advanced substantially. In diagnostics, technical progress in CT and MR imaging has led to a better three-dimensional understanding of the injury. Newly developed classification systems such as the three-column concept of Luo et al. and the 10-segment concept of Krause et al. take this into account. Accordingly, there is a trend towards tailored approaches for particular fracture localizations. Parallel to this development, there is increasing evidence of the advantages of arthroscopically assisted surgical procedures. This Current Concepts article reviews classifications, diagnostics, treatment options as well as complications in fractures of the proximal tibia.

A lateral fracture step-off of 2mm increases intra-articular pressure following tibial plateau fracture

INTRODUCTION

The aim of this study was to evaluate the effects of increasing posttraumatic step-offs after lateral tibial plateau fracture reduction on the intra-articular pressure.

MATERIALS AND METHODS

In eight fresh-frozen human cadaveric knees with intact menisci, a standardized sagittal osteotomy of the lateral tibial condyle was performed as an OTA/AO type 41-B1 fracture-model. The fragment was fixed by a customized sled including an angular stable tibia plate to evaluate step-offs from 0 mm to 8 mm in 1mm increments. In a servo-hydraulic testing machine, an axial force was applied to the tibial plateau in 0° (700N), 15° (700N), 30° (700N), 60° (350N), and 90 ° (350N) of flexion while the joint pressure was recorded by two pressure sensors.

RESULTS

A 1mm step-off did not result in an increased joint pressure. At 60° of flexion a 2mm step-off increased the lateral joint pressure by 61.84kPa (P = 0.0027). In 30° of flexion, a 3mm step raised the lateral joint pressure by 66.80kPa (p = 0.0017), whereas in 0°, 15° and 90° of flexion, a 4mm step increased the pressure by >50kPa (P < 0.05). Concomitant medial joint pressure increments were lower than those in the lateral plateau. A significant increase of 19-24kPa in the medial joint pressure was detected in 90° of flexion with a 1mm lateral step (P = 0.0075), in 15° and 60° of flexion with a 2mm step (P < 0.05), in 0° of flexion with a 4mm step (P = 0.0215) and in 30° of flexion with a 7mm step (P = 0.0487).

CONCLUSION

Lateral fracture step-offs of 2mm or larger should be reduced intraoperatively to avoid large increases in lateral joint pressure.

Is It Necessary To Add Soft Tissue Injury to the Classification in Tibial Plateau Fracture Management?

Background

A gold standard classification for the treatment of tibial plateau fractures with soft tissue injury has not been established yet.This study aimed to evaluate the usability of a novel modified classification that can provide preoperative information to the surgeon about soft tissue injuries in tibial plateau fractures.

Methodology

A total of 36 patients with tibial plateau fractures were included in the study. Patients’ age, gender, and affected sides were recorded. Injuries to the medial meniscus, lateral meniscus, anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament, and lateral collateral ligament were examined with preoperative magnetic resonance imaging. Soft tissue injuries were arranged according to the novel modified classification based on the Schatzker classification.

Results

The mean age of the study participants was 45 (19-76) years; 72% of the patients were men and 28% were women. Moreover, 44% and 56% of the patients had broken the right and left tibial plateaus, respectively. At least one soft tissue injury was detected in 29 (81%) patients. In 14 (39%) patients, two or more soft tissue injuries were observed. All patients were arranged according to the novel modified classification regarding ligament and meniscus injuries.

Conclusions

With this novel modified classification system, we think that having better information about the preoperative condition of the soft tissue injuries can change the surgical strategy in patients with tibial plateau fractures.

Arthroscopy-Assisted Reduction Percutaneous Internal Fixation Versus Open Reduction Internal Fixation for Tibial Plateau Fracture: A Systematic Review and Meta-analysis

Background:

Arthroscopy-assisted reduction percutaneous internal fixation (ARIF) has emerged recently as an alternative treatment method in treating lower-energy tibial plateau fractures. To date, the comparison of clinical efficacy between ARIF and open reduction internal fixation (ORIF) is limited, with divergent conclusions.

Purpose:

To review studies on the clinical efficacy of ARIF and ORIF in the treatment of tibial plateau fracture.

Study Design:

Systematic review; Level of evidence, 3.

Methods:

A search was conducted using the PubMed, Web of Science, Cochrane Library, and EMBASE databases between inception and August 20, 2020, for retrospective and prospective studies evaluating ARIF versus ORIF in the treatment of tibial plateau fracture. We identified 6 clinical studies that met the inclusion criteria, with 231 patients treated with ARIF and 386 patients treated with ORIF. The risk of bias and the quality of evidence of the included studies were assessed. The 2 treatment types were compared in terms of clinical results and complications by using odds ratios (ORs), mean differences (MDs), or standardized mean differences (SMDs), with 95% confidence intervals (CIs). Heterogeneity among studies was quantified using the I² statistic.

Results:

The quality of the studies was high. Compared with ORIF, treatment with ARIF led to better clinical function (SMD = 0.31; 95% CI, 0.14 to 0.48; I² = 15%; P = .0005), shorter hospital stay (MD = –2.37; 95% CI, –2.92 to –1.81; I² = 0%; P < .001), and more intra-articular lesions found intraoperatively (OR = 3.76; 95% CI, 1.49 to 9.49; I² = 66%; P = .005). There were no complications or significant differences between the techniques in the radiological evaluation of reduction.

Conclusion:

Compared with ORIF, the ARIF technique for tibial plateau fractures led to faster postoperative recovery and better clinical function and the ability to find and treat more intra-articular lesions during the operation. However, the radiological evaluation of reduction and complications were not significantly different between the 2 groups.

Improved Visualization by Central Subluxation of the Lateral Meniscus in Comminuted Lateral Tibial Plateau Fractures

The goal of surgical reconstruction of comminuted tibial plateau fractures is an anatomical reconstruction and stable fixation of the articular surface. This can be difficult due to poor visualization of the posterolateral and central segments of the articular surface of the proximal tibia. To improve visualization, the lateral approach can be extended with an osteotomy of the femoral epicondyle. In most cases, use of the extended lateral approach allows the whole lateral plateau to be visualized. Nevertheless, in some cases, an osteotomy alone is not enough to expose the entire fracture, especially the central segments of the tibial plateau. For these specific cases, we developed an additional technical trick that significantly improves articular visualization; the lateral meniscocapsular fibers are dissected allowing for central subluxation of the lateral meniscus, while leaving the anterior and posterior roots intact. With central subluxation of the lateral meniscus in comminuted tibial plateau fractures, the joint surface can be completely visualized, allowing an anatomical reduction even in highly complex fractures.

Comparison of outcomes of ORIF versus bidirectional tractor and arthroscopically assisted CRIF in the treatment of lateral tibial plateau fractures: a retrospective cohort study

Background

Lateral tibial plateau fractures (TPFs) are often treated with conventional open reduction and internal fixation (ORIF) through standard anterolateral sub-meniscal arthrotomy. There has been increasing support for “bidirectional rapid redactor” device-assisted closed reduction and internal fixation (CRIF) for treating TPFs. The aim of the present study is to compare the clinical and radiological outcomes between CRIF and ORIF procedures.

Methods

We performed a retrospective cohort study of 55 lateral TPF patients (Schatzker types I–III) who accepted surgical treatment at our trauma level 1 center between January 2016 and January 2018. They were divided into the CRIF group (32 patients) and the ORIF group (23 patients) based upon the different surgical protocols. The patients’ clinical outcome analysis was evaluated by using the Knee Society Score (KSS) and Rasmussen’s clinical score. For radiological assessment, changes in tibial plateau width (TPW), articular depression depth (ADD), medial proximal tibial angle (MPTA), and posterior tibial slope angle (PTSA) were evaluated using radiographs and computed tomography (CT) scan.

Results

The CRIF group had a mean follow-up of 28.9 months, and the ORIF group had a mean follow-up of 30.7 months (p>0.05). Furthermore, there was no statistically significant difference in terms of age, gender, injury mechanism, follow-up time, time interval from injury to surgery, and Schatzker classification in the two groups. With respect to the clinical outcomes including the KSS score and Rasmussen’s clinical score, there was also no significant difference (p>0.05). Nevertheless, the CRIF group had lower intra-operative blood loss, shorter hospitalization days, and better range of movement of the knee joint than the ORIF group (p<0.05). Furthermore, CRIF had better radiological results when compared to the ORIF group using Rasmussen’s radiological score (p<0.05), although no significant difference was observed in TPW, ADD, MPTA, and PTSA between the two groups (p>0.05).

Conclusion

The present study showed that CRIF could achieve comparable clinical outcomes and better radiological results for treating lateral TPFs as compared with conventional ORIF.

Schatzker II tibial plateau fractures: Anatomically precontoured locking compression plates seem to improve radiological and clinical outcomes

INTRODUCTION

The design of anatomically precontoured locking compression plates (LCP) allows the placement of angular stable screws right underneath the reduced joint surface fragments. To date, there is a lack of evidence supporting the broad utilization of these implants in split depression fractures to the lateral tibial plateau. Thus, aim of the present matched pair retrospective cohort study was to investigate the radiological and clinical outcomes of anatomically precontoured LCP compared to conventional plate and screw osteosynthesis in Schatzker II fractures.

MATERIAL AND METHODS

The institutional databank was searched for Schatzker II fractures from 2010 to 2016. Patients that underwent open reduction and internal fixation with anatomically precontoured 3.5 mm LCP or conventional 4.5 mm l-shaped plates and screws were included. CT scans and radiographs were analyzed. Details of the operative procedures and secondary events were collected. A matched pair analyses was conducted in a best fit manner. The primary outcome parameter was the Rasmussen Radiological Score approximately one year postoperatively. Secondary outcome parameters were the medial proximal tibial angle (MPTA), the Rasmussen Clinical Score and the WOMAC Score after a follow up of at least three years.

RESULTS

A total of 50 patients was included. Patient age, gender distribution, size and depression depth of the lateral joint surface fragments, frequency of utilizing bone grafts or substitutes and lateral meniscus repair as well as subsequent implant removal were comparable across the groups. Immediately postoperatively, the Rasmussen Radiological Score revealed no differences. After a mean of 64.2 weeks, the radiological outcome was significantly better in the LCP 3.5 group (RRS 8.2 vs. 6.3 points, p<0.001; MPTA 89.5 vs. 92.0°, p = 0.001). After a mean clinical follow-up of 4.5 years, the Rasmussen Clinical Score (22.9 vs. 27.8 points, p<0.001) and the WOMAC score (24.3 vs. 16.0 points, p = 0.04) revealed significantly impaired results in the conventional group.

CONCLUSION

Anatomically precontoured LCP prevent the subsidence of the reduced joint surface fragments more sufficiently and allow for improved patient outcomes compared to conventional plates and screws. The utilization of anatomically precontoured LCP should therefore closely be considered for internal fixation of any split depression fractures to the lateral tibial plateau.

Effect of fracturoscopy on the incidence of surgical site infections post tibial plateau fracture surgery

PURPOSE

Surgical treatment of tibial plateau fracture (TPF) is common. Surgical site infections (SSI) are among the most serious complications of TPF. This multicentre study aimed to evaluate the effect of fracturoscopy on the incidence of surgical site infections in patients with TPF.

METHODS

We performed a retrospective multicentre study. All patients with an AO/OTA 41 B and C TPF from January 2005 to December 2014 were included. Patients were divided into three groups: those who underwent arthroscopic reduction and internal fixation (ARIF), and those who underwent open reduction and internal fixation (ORIF) with fracturoscopy, and those treated with ORIF without fracturoscopy. The groups were compared to assess the effect of fracturoscopy. We characterised our cohort and the subgroups using descriptive statistics. Furthermore, we fitted a logistic regression model which was reduced and simplified by a selection procedure (both directions) using the Akaike information criterion (AIC). From the final model, odds ratios and inclusive 95% confidence intervals were calculated.

RESULTS

Overall, 52 patients who underwent fracturoscopy, 48 patients who underwent ARIF, and 2000 patients treated with ORIF were identified. The rate of SSI was 0% (0/48) in the ARIF group and 1.9% (1/52) in the fracturoscopy group compared to 4.7% (93/2000) in the ORIF group (OR = 0.40, p = 0.37). Regression analyses indicated a potential positive effect of fracturoscopy (OR, 0.65; 95% CI, 0.07-5.68; p = 0.69).

CONCLUSION

Our study shows that fracturoscopy is associated with reduced rates of SSI. Further studies with larger cohorts are needed to investigate this.

[Reduction and fixation of tibia plateau fractures : Tips and tactics based on the 3-column concept]

OBJECTIVE

The surgical management of tibial plateau fractures remains a challenge. The aim of surgery is the anatomical reconstruction of the joint surface with correct length, axis and rotation. The goal of osteosynthesis is to maintain a stable reduction to allow bone healing and functional aftercare. The continued advancements in 3D computed tomography has changed, the classification systems and, in parallel, the treatment strategies significantly changed. The 3‑column concept of Luo et al. has proven to be advantageous for planning of access, reduction and stabilisation.

INDICATIONS

Taking into consideration patient-specific factors. most displaced tibia plateau fractures are treated by surgery. However, no clear treatment recommendations exist in literature. In our clinical practice, joint displacement of more than 2 mm is generally not tolerated and surgical therapy is advised.

OPERATION TECHNIQUE

The surgical technique is preceded by the surgical strategy, which is based on the soft tissue situation and imaging results. The gold standard in imaging is computed tomography. Timing of surgery, patient positioning, surgical approaches as well as the implants are individually adapted to the fracture pattern.

RESULTS

The postoperative results are strongly influenced by fracture type, soft tissue condition, patient-specific factors, treatment method, and successful joint reconstruction. The functional postoperative results are often satisfactory even after complex tibia plateau fractures. In the literature, development of posttraumatic arthritis is reported to be 23-44%. In a study by Mehin et al. joint replacement of the knee was performed in 4.5% of cases following the surgical treatment of tibia plateau fractures.

Arthroscopically assisted reduction and internal fixation (ARIF) versus open reduction and internal fixation (ORIF) for lateral tibial plateau fractures: a comparative retrospective study

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.

A simple method for bone graft insertion during Schatzker II and III plateau fixation

Insertion of bone graft to fill metaphyseal defects and supply subchondral support when fixing Schatzker type II and III tibial plateau fractures can be difficult and tedious. Accurately directing the placement of bone graft through a small entry portal and against gravity can be challenging. Using a modified 3-mL syringe and bone tamps with application of the Seldinger technique can make this tedious task simple and more accurate.Level of evidence V.

Arthroscopy Assisted Reduction Percutaneous Internal Fixation versus Open Reduction Internal Fixation for Low Energy Tibia Plateau Fractures

The purpose of our study was to compare the curative effect of two surgical methods for Schatzker type I to III tibia plateau fractures, arthroscopy assisted reduction percutaneous internal fixation (ARIF) and open reduction internal fixation (ORIF), with the intent of evaluating the quality of evidence to assist treatment selection. Searches of PubMed, Cochrane and China National Knowledge Infrastructure (CNKI) databases were performed to identify randomized controlled trials (RCTs) and quasi-RCTs comparing ARIF and ORIF regarding the following outcomes: functional outcomes, perioperative complications and post-traumatic osteoarthritis. Odds ratios (OR) and weighted mean differences (MDs) were pooled using either a fixed-effects model or random-effects model, depending on the heterogeneity of the trials included in the analysis. 19 RCTs and one quasi-RCT provided the data from 1272 patients. ARIF was associated with better functional outcomes, a lower risk of perioperative complications, and lower risk of post-traumatic osteoarthritis. After consideration of the quality of evidence of the included studies, the advantages provided by ARIF are not substantive over ORIF for the treatment of Schatzker type I to III tibia plateau fractures, except reducing the risk of perioperative complications.

Percutaneous Reduction and Internal Fixation for Monocondylar Fractures of Tibial Plateau: A Systematic Review

Instead of extensive dissection of soft tissue around the fracture site, percutaneous techniques have unique advantages in managing displaced fragments, including preservation of soft tissues, less blood loss, lower risk of complications, and earlier functional rehabilitation. However, there are few systematic reviews on the effects of percutaneous reduction and internal fixation (PRIF) for tibial plateau fractures. A systematic search of Cochrane, EMBASE, and MEDLINE databases was performed for all publicly available data in March 2017 regarding the use of PRIF in treating monocondylar tibial plateau fractures. Basic information of included articles, surgical information, clinical outcomes, and concomitant soft tissue injuries were collected for analysis. Finally, a total of 20 articles including 561 patients were retrieved. Traffic accident was the most common cause of injury. Percutaneous techniques using bone tamp reduction were described in all studies. The majority (≥85%) of patients were classified as excellent or good according to clinical and radiological Rasmussen scores. The overall complication rate was 6.6%, with loss of reduction the most frequent complication with an incidence of 2.4%. This systematic review indicated that PRIF was an optimal alternative that physicians should consider for the treatment of monocondylar tibial plateau fractures.

Tibial plateau fracture management: arthroscopically-assisted versus ORIF procedure - clinical and radiological comparison

INTRODUCTION

Tibial plateau fractures are articular injuries that may influence final functional outcome of the knee. Although these fractures comprise only 1% of all fractures, the fracture pattern is usually complex and requires anatomical reduction and absolutely stable fixation to achieve satisfactory results. The development of knee osteoarthritis is a common late complication and it can be strongly influenced by additional, underestimated cartilage defects, and meniscal and ligament tears.

MATERIALS AND METHODS

Between January 2012 and February 2015, a total of 78 patients with tibial plateau fractures (Schatzker type I-III) were enrolled in the study. Patients were divided into two groups: one group was treated with arthroscopically-assisted reduction and internal fixation (ARIF) and the other with open reduction and internal fixation (ORIF). The final number of patients was 75; 40 in the ARIF group and 35 in the ORIF group. Radiography and computed tomography were used to assess fracture pattern. An immediate postoperative radiograph was performed, and then repeated at 6 weeks, and 3,6 and 12 months after surgery. Demographic data (age and sex), additional intraarticular injuries, hospital stay and complications were noted, and clinical and radiological Rasmunssen score at 3, 6 and 12 months after surgery were evaluated.

RESULTS

Additional intraarticular lesions were found in 27 patients; 20 in the ARIF group and 7 in the ORIF group (p = 0.06). There was a statistically significant difference in average duration of hospital stay: 3.10 ± 0.63 days for the ARIF group and 5.51 ± 1.66 days for the ORIF group (p = 0.0001). All fractures healed within 3 months following surgery. The overall complication rate was 12%. There was no statistically significant difference in complication rate between the two groups (p = 0.63). Clinical and radiological scores were excellent in most patients in both groups. There was no statistically significant difference in average clinical and radiological Rasmunssen scores between the two groups.

CONCLUSIONS

Both ARIF and ORIF can provide equally good results; however, ARIF seems to offer a more precise evaluation and treatment of associated intraarticular lesions and to reduce the duration of hospital stay.

Return to sport following tibial plateau fractures: A systematic review

AIM

To systemically review all studies reporting return to sport following tibial plateau fracture, in order to provide information on return rates and times to sport, and to assess variations in sporting outcome for different treatment methods.

METHODS

A systematic search of CINAHAL, Cochrane, EMBASE, Google Scholar, MEDLINE, PEDro, Scopus, SPORTDiscus and Web of Science was performed in January 2017 using the keywords “tibial”, “plateau”, “fractures”, “knee”, “athletes”, “sports”, “non-operative”, “conservative”, “operative”, “return to sport”. All studies which recorded return rates and times to sport following tibial plateau fractures were included.

RESULTS

Twenty-seven studies were included: 1 was a randomised controlled trial, 7 were prospective cohort studies, 16 were retrospective cohort studies, 3 were case series. One study reported on the outcome of conservative management (n = 3); 27 reported on the outcome of surgical management (n = 917). Nine studies reported on Open Reduction Internal Fixation (ORIF) (n = 193), 11 on Arthroscopic-Assisted Reduction Internal Fixation (ARIF) (n = 253) and 7 on Frame-Assisted Fixation (FRAME) (n = 262). All studies recorded “return to sport” rates. Only one study recorded a “return to sport” time. The return rate to sport for the total cohort was 70%. For the conservatively-managed fractures, the return rate was 100%. For the surgically-managed fractures, the return rate was 70%. For fractures managed with ORIF, the return rate was 60%. For fractures managed with ARIF, the return rate was 83%. For fractures managed with FRAME was 52%. The return rate for ARIF was found to be significantly greater than that for ORIF (OR 3.22, 95%CI: 2.09-4.97, P < 0.001) and for FRAME (OR 4.33, 95%CI: 2.89-6.50, P < 0.001). No difference was found between the return rates for ORIF and FRAME (OR 1.35, 95%CI: 0.92-1.96, P = 0.122). The recorded return time was 6.9 mo (median), from a study reporting on ORIF.

CONCLUSION

Return rates to sport for tibial plateau fractures remain limited compared to other fractures. ARIF provides the best return rates. There is limited data regarding return times to sport. Further research is required to determine return times to sport, and to improve return rates to sport, through treatment and rehabilitation optimisation.
