Posterior Tibial Plateau Fractures Research Articles

The combined internal and external fixation surgery is effective and safe in treating posterior lateral tibial plateau fractures: An observational study.

To investigate the treatment outcomes of combined internal and external fixation surgery for patients with posterior lateral tibial plateau fractures and explore its safety. The study was conducted from February 2020 to February 2023 and included a total of 77 patients with Schatzker IV and Schatzker V type posterior lateral tibial plateau fractures. Patients were divided into control group and treatment group according to different treatment methods: the control group with 38 cases received treatment with dual-support plates, and the study group with 39 cases received treatment with internal fixation using medial plates combined with lateral locking plates. Clinical indicators during treatment, immediate postoperative and 12-month postoperative radiographic indicators, Rasmussen knee joint function scores before and 3 months after surgery, knee joint function recovery, quality of life, and postoperative complications were recorded and compared between the 2 groups. The inter-group comparisons were made for intraoperative blood loss, surgical duration, and the time to start weight-bearing postoperatively (P > .05). The study group had shorter postoperative hospital stays and fracture healing times compared to the control group (P < .05). Immediately postoperatively, the medial tilt angle and posterior tilt angle in both groups were compared (P > .05). At 12 months postoperatively, the medial tilt angle decreased and the posterior tilt angle increased in both groups compared to immediately postoperative values (P < .05), with no significant difference between the groups (P > .05). However, at 3 months postoperatively, the scores for various dimensions in both groups increased compared to preoperative values, and the study group had higher scores than the control group (P < .05). However, at 3 months postoperatively, the quality of life scores were higher than preoperative values in both groups, with the study group having higher scores (P < .05). The occurrence of complications during the treatment period was compared between the 2 groups (P > .05). The medial and lateral combined plate fixation has a good clinical effect in the treatment of posterolateral tibial plateau fractures, which can shorten the fracture healing time, help the recovery of knee joint function and improve the quality of life of patients after operation, and has high safety in the treatment process.

Evaluation and Management of Posterior Tibial Plateau Fractures.

Tibial plateau fractures are caused by high-energy or low-energy trauma and result in complex injuries that require careful management of both osseous injuries and associated soft tissues. The posterior aspect of the tibial plateau can be involved in a variety of fracture patterns, requiring systematic evaluation, imaging, and advanced surgical planning to address these complex injuries. Early classification systems failed to classify posterior plateau fractures; however, three-dimensional imaging and newer classification schemes, including the Quadrant System and 3D systems, have incorporated posterior column lesions. There has been a growing body of literature focused on fixation principles and plating options for posterior column fractures. Furthermore, there are multiple approaches for surgeons to choose between, including a direct posterior, posteromedial, posterolateral (including Lobenhoffer and lateral condyle osteotomy), and combined posterior approach. This article presents a guide for managing posterior tibial plateau fractures, including the initial evaluation and management, descriptions of the surgical approaches, principles of fixation, and the associated outcomes and complications.

Outcomes of Anterior Lateral Approach and Gerdy's Tubercle Osteotomy for Tibial Plateau Fractures Involving the Posterior Lateral Condyle: A Retrospective Study of 20 Patients.

BACKGROUND The objective of this investigation was to assess the effectiveness of using T-shaped steel plates through the anterior lateral approach and Gerdy's tubercle osteotomy for treating posterior lateral tibial plateau fractures. MATERIAL AND METHODS A retrospective analysis was conducted on clinical data from 20 patients, aged on average 53.9±10.36 years, who were admitted for tibial plateau fractures involving the posterior lateral condyle between January 2019 and October 2022. The fixation and reduction of the posterior lateral bone block were performed using the anterior lateral approach combined with Gerdy's tubercle osteotomy to address the posterior lateral tibial plateau fracture. Post-surgery assessment was conducted using the Hospital for Special Surgery (HSS) knee combined score. RESULTS During the 12-24 (14.2±1.7) month postoperative period, we conducted 20 surgeries. Within 9 to 12 weeks, fracture healing transpired without any complications such as incision infection, nerve injury, or fracture displacement being detected. Assessment of knee joint function at the final follow-up was conducted using the HSS knee combined score, with results indicating 16 cases rated as excellent, 3 cases as good, and 1 case as fair. CONCLUSIONS In tibial plateau fractures impacting the posterior lateral condyle, the anterior lateral approach, combined with Gerdy's tubercle osteotomy, allows for direct exposure and manipulation of the posterior lateral bone block fracture. Using a T-shaped support plate and a lateral locking plate provides a reliable method for fracture fixation, aiding in convenient surgical positioning and intraoperative fluoroscopy. The treatment approach effectively manages fractures located on the posterior lateral aspect of the tibial plateau.

The Application of Posterior Plate in Tibial Plateau Fracture: A Case Report

Backgrounds: Tibial plateau fracture is the most frequent type of fracture caused by motor-vehicle collision. This injury may or may not be associated with soft tissue injury, such as the knee's ligaments. Posterior tibial plateau fractures are a rare subtype that requires surgical intervention. This case report describes the outcome of posterior plating in treating a posterior tibial plateau fracture. Case report: A 41-year-old female patient came to the emergency room (ER) after being involved in a traffic collision. The patient underwent a thorough medical examination, which revealed the tibial eminence avulsion associated with the fracture of the head of the fibula. Surgical treatment was performed using a posterior approach through an inverted L-shaped incision. Discussion: Tibial plateau fractures are serious injuries that often require surgery. However, the decision to operate depends on several factors, including the morphology of the fracture, the patient's profile, the condition of the soft tissues, and the expected recovery of the articular surface and the axis of the limb. Conclusion: A surgical technique using a posterior approach through an inverted L-shaped incision with a small medial T-plate, lateral bone graft, and roof K-wire fixation demonstrates positive outcomes for treating closed posterior tibial plateau fractures and avulsion fractures of the tibial eminence.

Newly designed plate for the treatment of posterolateral tibial plateau fractures: a finite element analysis

BackgroundThis study investigated the biomechanical properties of a new plate used for the treatment of posterolateral tibial plateau fractures using finite element analysis.MethodsThe study groups were as follows: group PM, model of the new plate with posteromedial tibial plateau fracture; group PL, model of the new plate with posterolateral tibial plateau fracture; and group PC, model of the new plate with posterior tibial plateau fracture. We used two loading modes: uniform loading on the entire plateau, and loading on the posterior plateau. Data such as the displacement of the fracture and distribution of stress on the new plate and screws were recorded and analyzed.ResultsWhen the whole plateau was loaded, the displacement of fractures in groups PM, PL, and PC were 0.273, 0.114, and 0.265 mm, respectively. The maximum stresses on the plates in groups PM, PL, and PC were 118.131 MPa, 44.191 MPa, and 115.433 MPa. The maximum stresses on the screws in Groups PM, PL, and PC were 166.731, 80.330, and 164.439 MPa, respectively. When the posterior tibial plateau was loaded, the displacement of the fractures in groups PM, PL, and PC was 0.410, 0.213, and 0.390 mm, respectively. The maximum stresses on the plates in groups PM, PL, and PC were 194.012 MPa, 72.806 MPa, and 185.535 MPa. The maximum stresses on the screws in Groups PM, PL, and PC were 278.265, 114.839, and 266.396 MPa, respectively.ConclusionThe results of this study revealed that titanium plates have good fixation effects in all groups; therefore, the use of the new plate for posterolateral tibial plateau fractures appears to be safe and valid.

The prone posteromedial approach to the knee revisited: a safe and effective strategy for posterior tibial plateau fractures.

To compare outcomes of patients with posterior tibial plateau fractures who underwent repair indirectly with an anterior approach to those who underwent direct repair with a prone "Lobenhoffer" operative approach. A total of 44 patients with a posterior column tibial plateau fracture that underwent repair were identified. Twenty-two patients with 22 tibial plateau fractures were fixed using a prone Lobenhoffer approach. They were compared to 22 patients treated with an indirect reduction using a supine approach for similar fracture patterns. Data collection at minimum 1year included: patient-reported outcome scores (SMFA), patient-reported pain, knee range of motion, complications and need for reoperation. Radiographs were reviewed for knee alignment, residual depression and fracture healing. All demographics were similar between the groups except BMI, which was lower in the prone group (P < 0.05). Fracture type according to age, Schatzker and three-column classification was matched between cohorts. There was no difference in outcomes including: pain, radiographic knee alignment, residual articular depression, functional outcome (SMFA), complications and need for reoperations. Knee flexion at 1year was greater in the prone group (127.8 vs. 115.8; P = 0.018). In addition, surgical time was less in the prone group (mean 73.7min vs. 82.3min; P = 0.015). The Lobenhoffer approach with direct reduction of posterior fracture fragments for complex tibial plateau fractures is an excellent option for these injuries. It allowed for faster surgery with improved ultimate knee range of motion in posterior column tibial plateau fractures.

Our Experience with Posterior Approach for Posterior Tibial Plateau Fractures.

Introduction: Posterior tibial plateau fractures are a rare type of fractures. Most surgeons are accustomed to operate in the supine position, however, surgery in the posterior knee region and operating in prone position can be challenging because of the presence of neurovascular structures including the tibial nerve, popliteal artery and vein, common peroneal nerve and, also challenging to achieve effective reduction and fixation, thus, it is less commonly performed. Materials and methods: Between February and September 2022 four posterior tibial plateau fractures were diagnosed and operated in our clinic within a six months follow-up (2 female and 2 male with mean age of 48.5 years). All were diagnosed with X-rays and CT scans. All of the fractures were on the right leg. Posterior "S shape" approach in prone position was used to reduce the tibial condyle and fix it with a plate. In fracture patterns that include lateral plateau impressions, the posterior "S shape" approach may not be sufficient to perform open reduction and internal fixation of the lateral condyle, so an additional anterolateral approach was made and additional locking plate was placed. Radiographic evaluation included reduction quality and satisfactory alignment of the bone axis. Results: All fractures healed within 6 months, without secondary displacement. Throughout the follow-up period, there were no incidences of post-traumatic osteoarthritis of the knee. No patient complained of knee instability. Conclusion: The direct dorsal approach allowed for adequate open reduction and internal fixation, and early clinical results are promising. However, in fracture patterns that include lateral plateau impressions, the posterior "S shape" approach may not be sufficient to perform open reduction and internal fixation of the lateral condyle, so an additional anterolateral approach should be made and additional locking plate to be placed.

Comparative Analysis of Posterior Approach Versus Anterior Approach for Posterior Tibial Plateau Fractures: A Systematic Review and Meta-analysis.

Posterior tibial plateau fractures can lead to significant posttraumatic instability if not treated properly. It remains unclear which surgical approach achieves better patient outcomes. The objective of this systematic review and meta-analysis was to assess postoperative outcomes in patients undergoing anterior, posterior, or combined approach for posterior tibial plateau fractures. The PubMed, Embase, Web of Science, The Cochrane Library, and Scopus were searched for studies published before October 26, 2022, comparing anterior, posterior, or combined approaches for posterior tibial plateau fractures. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Outcomes included complications, infections, range of motion (ROM), operation time, union rates, and functional scores. Significance was set at p < 0.05. Meta-analysis was conducted with STATA software. In total, 29 studies with a total of 747 patients were included for quantitative and qualitative analysis. Compared with other approaches, the posterior approach for posterior tibial plateau fractures was associated with a better ROM and shorter operative time. The complication rates, infection rates, union time, and hospital for special surgery (HSS) scores were not significantly different between surgical approaches. The posterior approach for posterior tibial plateau fractures offers advantages such as improved ROM and shorter operative time. However, there are concerns regarding prone positioning in patients with medical or pulmonary comorbidities and indications in polytrauma cases. Further prospective studies are needed to determine the optimal approach for these fractures. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Clinical application of the modified posterolateral approach for treating posterior tibial plateau fractures.

Objective: To investigate the therapeutic efficacy of the modified posterolateral approach on tibial plateau fractures. Methods: Forty-four patients with tibial plateau fractures were enrolled in the study and divided into two groups-control and observation-according to the different surgical procedures. The control group underwent fracture reduction via the conventional lateral approach, while the observation group underwent fracture reduction via the modified posterolateral strategy. The depth of tibial plateau collapse, active mobility, and the Hospital for Special Surgery (HSS) score and Lysholm score of the knee joint at 12months after surgery were assessed in comparison to the two groups. Results: The amount of blood loss (p < 0.01), duration of surgery (p < 0.05), and depth of tibial plateau collapse (p < 0.001) were significantly less in the observation group compared with the control group. In addition, compared with the control group, the observation group exhibited significantly better knee flexion and extension function and significantly higher HSS and Lysholm scores at 12months after surgery (p < 0.05). Conclusion: The modified posterolateral approach for posterior tibial plateau fractures has less intraoperative bleeding and a shorter operative time compared with the conventional lateral approach. It also effectively prevents postoperative tibial plateau joint surface loss and collapse, promotes the recovery of knee function, and has few postoperative complications and good clinical efficacy. Thus, the modified approach is worth promoting in clinical practice.

A preliminary study of the surgical approach for posterior tibial plateau fractures: Based on posterior fragment segment classification

PurposeThe optimal surgical approach for the posterior tibial plateau fractures (PTPFs) remains controversial. This study aims to establish a method for posterior fragment segment classification to guide the choice of surgical approach and to reveal the outcome of their early reduction and health status. MethodsThe medical records of 42 PTPFs patients treated with the strategy were collected retrospectively from December 2017 to December 2021. The posterior cortex of the tibial plateau was classified into postero-medial (PM), postero-central (PC), and postero-lateral (PL) segments. A posteromedial inverted L-shaped approach was adopted when the fractures involved the PM segment in the presence or absence of PC. The Frosch approach was performed when the PL segment was concerned. Fractures containing both PM and PL segments were treated by combined approaches. Four factors were measured to evaluate the reduction effect, including medial proximal tibial angle (MPTA), lateral posterior slope angle (LPSA), medial posterior slope angle (MPSA), and articular step-off. The Short Form 36 (SF-36) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores were completed at the last follow-up to assess health status and the degree of osteoarthritis. ResultsA posteromedial inverted L-shaped approach was adopted in 16 PTPFs patients, a Frosch approach was adopted in 14 PTPFs patients, and a combined approach was adopted in 12 PTPFs patients. Immediate radiographic results indicated a promising fixation performance with this treatment strategy. The results of SF-36 and WOMAC scores reported good health status in all patients with a mean follow-up time of 34.50 (23–50) months. Two patients developed superficial wound infections, and one patient had liquefaction necrosis in adipose tissue. Although skin numbness occurred in 4 patients, they recovered within 6 months. ConclusionPTPFs patients treated under the guidance of posterior fragment segment classification achieved encouraging levels of immediate fixation and health status.

A Physical Therapist's Experience as a Point-of-Contact Care Provider in a Wilderness Environment: A Case Series Report

Background Wilderness physical therapists (WPTs) are on-scene primary providers who combine physical therapy, emergency first aid, and wilderness survival skills to manage people with a wide array of injuries and illnesses in remote environments. Case Presentation Patient 1, a 51-year-old female, was unable to bear weight after sustaining a right knee injury from falling into a river while hiking. The WPT immobilized a suspected knee fracture using a SAM® Splint, moved the patient and her group to safer location, and constructed a shelter. Shortly after, patient 2, a 14-year-old male, fell and sustained a forehead laceration. Hemostasis was obtained and the patient was monitored for neurologic abnormalities. Safety was complicated by rainfall, darkness, and the absence of cell service to notify emergency medical services. Outcome and Follow-Up Emergency medical services arrived 4 hours after the initial injury and evacuated both individuals. Plain film radiographs of patient 1's knee were interpreted as normal; however, subsequent magnetic resonance imaging revealed a posterior tibial plateau fracture with ligamentous injury. Following a 20-hour observation period, patient 2 was returned to continue the hike with his group. Discussion This case illustrates the emergency medical, leadership, and situational awareness skills required of a WPT. This case also illustrates the in-field application of the Ottawa knee rules and the importance of careful neurologic assessment in individuals with head trauma. JOSPT Cases 2022;2(3):175–182.

Management of posterior column tibial plateau fracture via a posterior approach

Background: Posterior tibial plateau fracture (PTPF) is a relatively uncommon injury. This kind of fracture appears confusing on initial radiographs because of the small displacement, so it is a special injury pattern. Aim and objectives: the aim of the study was to evaluate the safety and efficacy via a posterior approach in the posterior shearing tibial plateau fracture. Subjects and methods: The study was prospective study carried out in the Department of Orthopaedic surgery, Al-azhar university Hospital in Damietta. This study had been carried out on 24 patients. Results: there is statistically significant difference between immediate post-operative reduction and other post-operative reduction after 6 weeks, 3 months and 5 months. Conclusion: Posterior tibial plateau fracture is relatively rare in tibial plateau fractures. Our study highlights the importance of posterior tibial plateau fracture which was deemed unimportant in the past. Our results highlight the importance of fixation of PTPF and achieving an early and satisfactory functional outcome.

Outcomes of the Carlson Approach in the Treatment of Posterior Tibial Plateau Fractures.

Objectives To describe a series of cases of tibial fractures surgically treated using the posterior approach as described by Carlson, focusing on evaluating its functional results and complication rate. Methods Eleven patients with tibial plateau fractures, who underwent surgical treatment using the Carlson approach from July to December 2019, were followed-up. The minimum follow-up period was defined as 6 months. The American Knee Society Score (AKSS), American Knee Society Score/Function (AKSS/Function) and the Lysholm score were used to check treatment results at 6 months after the fracture. The patients underwent standard anteroposterior and lateral radiographs to assess fracture healing, and clinical healing was determined by the absence of pain during full weight-bearing. Results The mean follow-up period was 12 months (9-16 months). The primary mechanism of trauma was motorcycle accident, and the most prevalent side of fracture was the right side. Eight participants were male. The mean age of the patients was 28 years. All fractures healed, and none of the patients presented complications. The AKSS was excellent in 11 patients, with a mean AKSS/Function of 99.1 ± 3, and Lysholm scores with a median of 95.0 ± 5.6. Conclusions The Carlson approach for posterior fractures of the tibial plateau can be considered safe, presenting a low complication rate and satisfactory functional results.

Posteromedial tibial plateau fractures – Functional outcome of posteromedial buttress plating with precontoured locking plate using modified lobenhoffer approach

Posterior tibial plateau fractures have a complex intra-articular fracture pattern, representing approximately 1.2% of all fractures. The occurrence of the posteromedial shear fragment is relatively common in high-energy tibial plateau fractures. Aims and Objectives: To study the role of posteromedial plating in the management of complex tibial plateau fractures with a posteromedial fragment. Materials and Methods: Only patients with posteromedial fracture patterns alone are taken into account. Twenty cases above 20 years of age, from the patient, admitted to Government Medical College, Thrissur, with posteromedial fragment in tibial plateau fractures that were operated were undertaken for the study. The patients were followed up for 2 years. Results: Of the 20 patients with posteromedial tibial plateau fractures from X-ray and computed tomography scan of the knee joint, all patients were treated with precontoured posteromedial buttress plating using single anatomical locking plate. We analyzed patients with Rasmussen scoring postoperatively. In our analysis, among 20 patients, the functional score was excellent in 14, good in 5, fair in 1, and poor in none. There was one patient with compartment syndrome who had developed a mild surgical site infection that later resolved. No excessive collapse is seen postoperatively since locked plate is used. Four patients had transient paraesthesia of the saphenous nerve; both resolved completely.

Different patterns of tibial plateau fractures associated with hyperextension injuries of the knee with or without varus/valgus component.

This study aims to introduce a morphological classification of hyperextension tibial plateau fractures based on CT scans and to reveal the correlation between the anterior compression and posterior tension fractures.From January 2015 to January 2019, 37 patients with hyperextension tibial plateau fractures were studied retrospectively. Based on this classification, the fractures were divided into 2 groups: group A had anterolateral or anteromedial compression fractures while group B had both. Three observers classified the fractures and recorded the morphology and incidences of posterior plateau fractures and proximal fibular fractures.All 37 fractures were allocated to group A (n = 15; 40%) and B (n = 22; 60%). Of the posterior tibial plateau fractures, 10 (27%) fractures were defined as partial and 27 (73%) as total. Of the 37 fractures, 18 (49%) proximal fibular avulsion fractures were observed. There was a significant difference between groups A and B regarding the incidence of total posterior tibial plateau fractures (P < .05). However, there was no significant difference between the incidence of proximal fibular avulsion fractures in the 2 groups or the combined and non-combined type fractures in group B (P > .05).Hyperextension tibial plateau fractures with a decreased posterior slope angle always involve both the anteromedial and anterolateral plateaus. This CT-based classification may improve the understanding of fracture features and is helpful for planning treatment.

A modified Frosch approach for posterior tibial plateau fractures: Technical note and case series

Achieving the best possible articular congruity following a tibial plateau (TP) fracture is associated with better long-term functional outcomes; TP has an essential role in the movements of the knee joint and is well established that a not optimal reduction leads to articular instability and early osteoarthritis.In recent times, 3D reconstruction from CT scan has greatly contributed to improve the surgical treatment of these fractures since an accurate preoperative plan gives the possibility to decide the best interventional strategy before the surgical incision.Reduction of the posterior part of tibial plateau is not easily achievable with standard surgical access.Several posterolateral approaches, proposed by authors such as Frosch and Lobenhoffer, have been described over the years; these approaches can be divided into 2 groups: with or without osteotomy of the fibula.Main disadvantages of these techniques are the large skin incision, the difficulty of exposing the lateral part of the tibia, the high frequency of damages of the posterolateral TP corner, and in some cases the necessity of performing fibular head osteotomy.The surgical approach presented in this paper is a simple innovation of the well-known Frosch approach: skin incision is about 12 centimeters in length and runs in a “S” shape with the center positioned over the head of the fibula. It starts 2 centimeters laterally to the tibial crest 6 centimeters below the tibial tuberosity and is directed proximally, curving posteriorly at the level of fibular head and returning straight in the most proximal part; it terminates 4 centimeters posteriorly the lateral femoral condyle.This innovative approach allows the trauma surgeon to achieve an optimal exposure and control of posterior tibial plateau fractures, with the great advantage of being able to treat the lateral tibial plateau with the same surgical incision.

Posterior tibial plateau fracture treatment with the new WAVE posterior proximal tibia plate: feasibility and first results.

Operative management of posterior tibial plateau fractures (PTPF) remains challenging. The treatment goal is to restore the alignment and articular congruence, and providing sufficient stability which allows early mobilization. The purpose of this study was to assess the feasibility and safety of the newly developed WAVE posterior proximal tibia plate. Between Oct 2017 and Jun 2020, 30 adult patients with a tibial plateau fracture and posterior involvement were selected for treatment with a WAVE posterior proximal tibia plate. Patient reported outcome was assessed using the Knee injury and Osteoarthritis Outcome Score (KOOS) at time of injury (pre-injury) and at 1-year follow-up. Radiological outcome was evaluated with CT-imaging. Twenty-eight patients were eligible for treatment with the new implant (3 'one-column', 10 'two column' and 15 'three-column' fractures), whereas in 2 patients anatomical fit was insufficient. KOOS results showed fair outcome scores at 1 year, with a large negative impact compared to pre-injury levels; however, a trend towards better results compared to a previous PTPF reference cohort. Radiological follow-up showed insufficient posterolateral buttress in two cases and residual articular step-off (> 2mm) in seven patients, of which five were classified as three column fractures. Management of PTPF using the WAVE posterior proximal tibia plate is feasible and safe with satisfactory clinical and radiological results after 1 year. Nevertheless, there is a learning curve regarding optimal implant positioning to achieve the maximum benefit of the implant.

The "FCR" Approach to the Knee for the Management of Posterior Tibial Plateau Fractures.

Three-column fixation of tibial plateau fractures is now an established philosophy. A direct posterior approach with the patient prone affords enhanced exposure of the posterior column and ease of access for fixation using a buttress plate and posterior-to-anterior screws. A "direct posterior" approach through a reverse L-shaped incision to back of the knee is popular, yet complications associated with raising a fascial flap can occur. We present a simple method of conceptualizing a direct posterior approach through a single longitudinal incision, by likening it to a commonly performed orthopedic approach, the flexor carpi radialis approach to the wrist.

FIXATION OF POSTERIOR TIBIAL PLATEAU FRACTURE AND ITS OUTCOME: A COMPARATIVE STUDY

Introduction: Tibial plateau fractures are complex injuries of proximal tibia which are produced by high- or low-energy trauma and principally affect young adult population. These fractures usually have associated soft-tissue lesions affecting the treatment. Posterior tibial plateau fractures (PTPF), may be medial or lateral, are common and they occur in about 28.8% patients as a part of bicondylar tibial plateau fractures. These fractures are difficult to reduce, therefore articular incongruity was not found to be detrimental factor in final functional outcomes. Studies have supported the fact that residual articular incongruence is well tolerated by proximal tibial plateau fracture in the form of minimal functional limitation or onset of arthrosis. Anterolateral and anteromedial surgical approaches do not show adequate reduction and fixation of posterolateral and posteromedial fragments. To achieve this, it is advised to reduce and fix the fracture through specific posterolateral or posteromedial approaches that allow optimal reduction and plate/screw placement. &#x0D; Material and Methods: This comparative prospective cohort study on done on 50 adult patients. Two groups were formed: Group A – double-plate fixation with both posterior and anterolateral having 25 participants and Group B – single anterolateral plate fixation having 25 participants in PTPFs were followed up to 1 year. For Group A, the reduction was done under direct vision and assisted with fluoroscopy in two planes. The reduction was assessed with submeniscal approach. In Group B posterior fragment was reduced by screws through the anterolateral plate followed by CT scan. Patients were evaluated by radiographs every 6 weeks till fracture union is evident. Fracture union was assessed by cortical continuity and progressive loss of fracture line on X-rays. Functional status at 1-year postoperative CT scanogram was done at final follow up to record articular subsidence, nonunion, coronal, or sagittal deformities. Knee functions were assessed by the International Knee Documentation Committee 2000 subjective knee evaluation form and objective functional Knee Society Score (KSS).&#x0D; Results: There were 22 male and 3 female in Group A while in Group B there were 20 male and 5 female. Right tibial fracture was observed in 15 cases and left in 10 cases in group A while in Group B right fracture was seen in 17 cases and in 8 cases left sided fracture. 23 cases each in group A and B were associated with RTA. Operative time (minutes) in group A and group B was 124 ± 26.7 and 79.52± 16.22 respectively. Total mean hospitalization days were 9.4±2.6 in group A and 8.2±1.5 in group B. Union time in group A was 14.6±3.4 weeks while in group B was 15.4±3.2. Statistically significant correlation was observed in group A and B with respect to KSS clinical outcome and KSS functional outcome. Flexion deformity was observed in 3 (12%) cases in group A and in 6 (24%) cases in group B.&#x0D; Conclusion: PTPF can achieve an early and satisfactory functional outcome. Rehabilitation and fracture healing are better in PTPF.&#x0D; Keywords: Tibial plateau fractures, PTPF, Open reduction and internal fixation (ORIF)

Fixation of Posterior Tibial Plateau Fracture with Additional Posterior Plating Improves Early Rehabilitation and Patient Satisfaction.

Introduction:Posterior tibial plateau fractures (PTPF) are difficult to manage because of options of multiple approaches, paucity of implants, and lack of ideal construct for fixation. We investigated the benefits of using posterior approach and buttress plate for fixation of the posterior tibial condylar fractures in terms of the fracture healing rate, clinico-radiological, perioperative morbidity, and patient-related outcomes and compared them in those who achieved acceptable reduction without posterior stabilization.Patients and Methods:Seventy two patients with posterior tibial plateau fractures were prospectively followed after random allocation into two Groups A and B. Thirty eight patients of Group A (dual plating) were managed with stabilization of posterior fragment with Lobenhoffer approach in addition to anterolateral plating. Thirty four patients of Group B (single plate) were managed with isolated anterolateral plating after reducing the PTPF. Twelve patients lost to follow-up and sixty patients were available (thirty in either group) for final assessment. Followup was done by clinical examination, radiographs and computed tomography scan, fracture union, articular continuity, and deformities around the knee. Subjective outcome assessment was done with the International Knee Documentation Committee (IKDC) 2000 and Knee Society Score (KSS).Results:At 1-year followup, the two groups did not differ in time of fracture union. IKDC and KSS were significantly better in dual-plating group (P < 0.001). Mean operative time and blood loss were more in dual-plating group (A). The mean hospital stay and complications did not show significant differences.Conclusion:Addition of posterior approach for stabilization of the posterior fragment in posterior tibial plateau fractures achieves early and improved knee functions, good range of movements, minimal deformities, and pain scores by the time fracture unites. However, peri-operative morbidity, Extra implant costs and increased operative time are its disadvantages.
