J Orthop Sci 2024; 29:1085-1090. [PMID: 37393110 DOI: 10.1016/j.jos.2023.06.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 05/10/2023] [Accepted: 06/15/2023] [Indexed: 07/03/2023]
Abstract
BACKGROUND Fixing the posterolateral fragments of tibial plateau fractures has been challenging owing to potential neurovascular injuries and fibular head blocks. Several surgical approaches and fixation techniques have been reported, with distinct limitations. We propose a novel lateral tibia plateau hook plate system and compare its biomechanical stability with other fixation methods. METHODS Twenty-four synthetic tibia models were simulated to present posterolateral tibial plateau fractures. These models were randomly assigned to three groups. Group A models were fixed with the lateral tibia plateau hook plate system, Group B with variable-angle anterolateral locking compression plates, and Group C with direct posterior buttress plates. The models' biomechanical stability was evaluated using static (gradually increased axial compressive loads) and fatigue (cyclically loaded from 100 to 600 N for 2000 cycles each) tests. RESULTS Groups A and C models exhibited comparable axial stiffness, subsidence load, failure load, and displacement in the static test. Group A model exhibited higher subsidence and failure loads than Group B model. Groups A and C models exhibited comparable displacement at 100 N cyclic loading in the fatigue test. Group C model was more stable at higher loads. Group C model endured the highest subsidence cycle numbers, followed by Groups A and B models. CONCLUSIONS The lateral tibia plateau hook plate system provided similar static biomechanical stability as the direct posterior buttress plates and comparable dynamic stability under limited axial loading. This system is a potential posterolateral treatment choice owing to its convenience and safety, in treating tibia plateau fractures.

Abstract
BACKGROUND Tibial plateau fractures involving posteromedial (PM) and posterolateral (PL) columns are complex injuries that require an appropriate approach. The management of the PL column in these cases can be controversial, and limitations using deep posteromedial interval approaches have been referenced. In this paper, a modification of the Lobenhoffer approach, designed to optimize the access to the PL column, is described in detail. The aim of this study was to assess the feasibility of this approach in a cadaveric anatomical study. MATERIALS AND METHODS In total, five fresh-frozen cadaveric specimens were used for detailed anatomical study surrounding the approach. Relationships with cutaneous and deep neurovascular structures were evaluated. The exposure area of the PL and PM columns using this approach was assessed. RESULTS The cadaveric study showed safe and adequate exposure. Oblique skin and fascia incision just medial to the posterior midline was safe to protect the medial sural cutaneous nerve and the small saphenous vein. Elevation of the popliteus and tibialis posterior muscles offered safe protection of the anterior tibial artery and popliteal neurovascular bundle during retractor placement. Adequate full proximal exposure of the PM and PL columns, including the posterolateral lateral (PLL) and posterolateral central (PLC) segments, was obtained in all specimens. CONCLUSIONS The Modified Oblique Lobenhoffer (MOL) approach can be a feasible option to access PL and PM columns in tibial plateau fractures. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND There has been controversial for the treatment of the posterolateral tibial plateau fractures (PTPF). This study aimed to evaluate clinic outcomes of the lateral locking compression plate (LCP) postposition, analyze the feasibility of LCP postposition through anatomical measurement, and address the potential problems of LCP postposition through the biomechanical assessment. METHODS 39 patients with PTPF undergoing LCP fixation between June 2019 and June 2022 were retrospectively evaluated. All cases were divided into two group: Group A (15 cases) employed plate transverse arm postpositioning with posterolateral (PL) fracture fixation using two raft screws, while Group B (24 cases) utilized non-postpositioning with fixation by a single raft screw. Surgical duration, intraoperative blood loss, the change of lateral tibial plateau angle (LTPA), lateral tibial plateau posterior slope angle (LPSA) and fracture collapse between immediate postoperative and last follow up, range of motion (ROM), HSS knee score, and Lysholm knee score were recorded. CT measurements of the fibular head superior space and LCP transverse arm were taken in 50 healthy adult knees to assess postposition feasibility. Finally, three fracture models were established using finite element analysis: Model A with plate postposition and PL split fracture fixed by two raft screws of transverse arm, Model B with plate non-postposition and PL split fracture fixed by one raft screw, and Model C with plate non-postposition and PL split fracture fixed by one raft screw and anterior-posterior tension screws. Loadings of 250N, 500N, and 750N were applied for the analysis of the displacement degree, von Mises stress distribution. RESULTS Results indicate comparable operative duration and intraoperative hemorrhage between groups. Complications were minimal in both groups. Group A demonstrated superior outcomes in terms of radiographic parameters, functional scores, and fracture collapse prevention. CT measurements revealed compatibility in 72% of healthy knees with the postpositioning technique. Finite element analysis indicated favorable biomechanical stability. CONCLUSION Not all patients with PTPF were applicable to the management of the plate postposition and two raft screws fixation, even though this technique exerted good biomechanical stability and achieved satisfactory clinic outcomes. When the PL fracture was fixed by only raft screw through LCP owing to various reasons, two anterior-posterior tension screws might be necessitated to maintain the fracture stability.

Orthop Surg 2023; 15:2974-2984. [PMID: 37706250 PMCID: PMC10622288 DOI: 10.1111/os.13890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2023] [Revised: 08/16/2023] [Accepted: 08/17/2023] [Indexed: 09/15/2023] Open
Abstract
OBJECTIVE The treatment of posterolateral tibial plateau fractures is difficult, and providing sufficient exposure and effective fixation is a challenge. There is great controversy regarding the surgical approach for posterolateral tibial plateau fractures. The purpose of the study was to investigate the clinical effects of open reduction and internal fixation using the Frosch approach for the treatment of posterolateral tibial plateau fractures combined with lateral tibial plateau fractures. METHODS Data from 19 patients with posterolateral tibial plateau fractures combined with lateral tibial plateau fractures treated from May 2018 to January 2022 were retrospectively analyzed. There were nine men and 10 women, ranging in age from 22 to 62 years, with an average age of 45.6 years. All patients were treated using the Frosch approach. Under direct vision, the posterolateral and lateral fractures were reduced, and full bone grafting was performed. We reshaped the oblique "T" shaped plate for the distal radius and placed it on the posterolateral tibial plateau to fix the posterolateral fractures. The lateral inverted "L" shaped locking plate was placed on the lateral tibial plateau to fix the lateral tibial plateau fractures. Within 2 weeks after the operation, the patients were instructed to perform knee joint function exercises within 90°. At the last follow-up, the Rasmussen radiological criteria were used to evaluate the effectiveness of fracture reduction and fixation. And the knee joint function was evaluated using Rasmussen functional score. RESULTS The operation time ranged from 100 to 180 min, with an average of 134.2 min; intraoperative blood loss ranged from 20 to 150 mL, with an average of 66.8 mL. The follow-up duration ranged from 14 to 58 months, with an average of 36.2 months. There were no complications, such as vascular or nerve injury or incision infection. Fracture healing was achieved in all patients, and the healing time ranged from 10 to 14 weeks, with an average of 11.2 weeks. During the follow-up period, there was no loosening or breakage of the internal fixation, varus or valgus deformity of the knee joint, re-collapse of the articular surface, or instability of the knee joint. At the last follow-up, the effectiveness of fracture reduction and fixation was excellent in 13 patients and good in six patients. And the knee joint function was excellent in 17 patients and good in two patients. CONCLUSION The Frosch approach for open reduction and internal fixation in the treatment of posterolateral tibial plateau fractures combined with lateral tibial plateau fractures has a definite clinical benefit and is worthy of promotion and application.

Medial Head of the Gastrocnemius Tenotomy Through a Posteromedial Approach Significantly Improves Surgical Accessibility of the Tibial Plateau. J Orthop Trauma 2023; 37:44-49. [PMID: 35947746 DOI: 10.1097/bot.0000000000002462] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 07/19/2022] [Indexed: 02/02/2023]
Abstract
OBJECTIVES Compare accessible area of the posterior tibial plateau through a modified posteromedial (PM) approach before and after tenotomy of the medial head gastrocnemius. We report the outcomes of 8 patients who underwent gastrocnemius tenotomy during PM approach. METHODS A modified PM approach was performed on 10 cadaveric legs, and the surgically accessible area was outlined. Next, a medial head gastrocnemius mid substance tenotomy was completed, and the accessible area was again outlined. Tibia specimens were imaged in a micro-CT scanner to measure accessible surface area and linear distance along the joint line. In addition, 8 patients who underwent tenotomy for tibial plateau fracture had outcomes recorded. RESULTS The modified PM approach with tenotomy provided significantly more access to the posterior plateau than without tenotomy. The modified PM approach before tenotomy allowed access to 1774 mm 2 (SD = 274) of the posterior plateau surface and 2350 mm 2 (SD = 421, P < 0.0001) with tenotomy. A linear distance of 38 mm (SD = 7) and 57 mm (SD = 7, P < 0.00001) was achieved before and after tenotomy, respectively. In the clinical series, the average knee arc of motion was 116 degrees (95-135). CONCLUSIONS The modified PM approach with medial head gastrocnemius tenotomy significantly improves surgical access to the posterior plateau. Patients who received tenotomy have acceptable functional outcomes. This cadaveric study provides an alternative approach for treatment of posterolateral tibial plateau fractures which may mitigate damage to neurovascular structures.

Abstract
PURPOSE The 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. METHODS The 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. RESULTS A 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. CONCLUSION PTPFs patients treated under the guidance of posterior fragment segment classification achieved encouraging levels of immediate fixation and health status.

Abstract
OBJECTIVE To investigate the effectiveness of a new tibial plateau posterolateral column universal locking anatomical plate (hereinafter referred to as "new universal locking anatomical plate") in the treatment of tibial plateau posterolateral column fractures. METHODS Between October 2020 and December 2021, 14 patients with tibial plateau posterolateral column fracture were treated with a new universal locking anatomical plate. There were 7 males and 7 females with an average age of 59 years ranging from 29 to 75 years. There were 5 cases on the left side and 9 cases on the right side. The causes of injury included falling from height in 5 cases, traffic accident in 7 cases, and other injuries in 2 cases. The time from injury to operation ranged from 3 to 10 days, with an average of 6 days. According to Schatzker classification, there were 4 cases of type Ⅱ, 8 cases of type Ⅴ, and 2 cases of type Ⅵ. All fractures involved the posterolateral tibial plateau. Three column classification: two columns (anterolateral column+posterior column) in 4 cases, three columns in 10 cases. The operation time, intraoperative blood loss, fracture healing, and complications were recorded. The reduction of tibial plateau fracture was evaluated by Rasmussen radiographic score, and the recovery of knee function was evaluated by Hospital for Special Surgery (HSS) score. RESULTS All 14 cases completed the operation successfully. The operation time was 95-180 minutes, with an average of 154 minutes, and the intraoperative blood loss was 100-480 mL, with an average of 260 mL. All patients were followed up 6-19 months, with an average of 12.5 months. All fractures healed, and the healing time was 15-24 weeks, with an average of 18.7 weeks. During the follow-up, there was 1 case of common peroneal nerve palsy and 1 case of traumatic osteoarthritis. There was no other complication such as vascular injury, incision infection, deep venous thrombosis of lower limbs, heterotopic ossification, bone nonunion, and failure of internal fixation. The reduction of tibial plateau fractures was good immediately after operation, and the Rasmussen radiological score was 10-18, with an average of 15.7; 3 cases were excellent, 10 cases were good, and 1 case was fair, with an excellent and good rate of 92.9%. The scores and grades of HSS at 3 months after operation and at last follow-up significantly improved when compared with those before operation ( P<0.05). There was no significant difference between 3 months after operation and last follow-up ( P>0.05). CONCLUSION For the fractures involving the posterolateral column of the tibial plateau, the new universal locking anatomical plate can provide strong fixation, satisfactory postoperative fracture reduction, and good recovery of knee function.

Abstract
Approaches for treating posterolateral tibial plateau fractures vary among surgeons, and the inverted L-shaped approach is a known option. This article aims to introduce a new modified posterolateral inverted L-shaped approach for isolated posterolateral tibial plateau fractures and study its feasibility. Medical records of patients with posterolateral tibial plateau fractures were reviewed. Plain radiographs were obtained during the follow-up period, and the hospital for special surgery (HSS) score was used to assess the function of the injured limb. Perioperative complications were recorded and followed-up. In total, 32 patients with posterolateral tibial plateau fractures were treated using a modified posterolateral approach. The mean age of the patients was 44 ± 11 years (28-64 years). All patients successfully underwent surgery and were followed-up for a mean duration of 13 ± 2 months (10-16 months). On plain radiographs, fracture lines were fuzzy 3 months after surgery and disappeared 12 months after surgery. No perioperative complications occurred during the follow-up period. The HSS score was evaluated 12 months after surgery, and the mean score was 91 ± 5 points (81-97 points), including 25 excellent cases and 7 good cases. The modified posterolateral inverted L-shaped approach has the advantages of small soft tissue dissection, fracture reduction under direct vision, easy internal fixation, and a lower risk of neurovascular injury. This approach is feasible for the treatment of isolated posterolateral tibial plateau fractures, and further high-quality randomized control trials are required to confirm its clinical efficacy.

Lateral locking plate plus antero-posterior lag screws techniques for the management of posterolateral tibial plateau fracture: preliminary clinical results and biomechanical study. Arch Orthop Trauma Surg 2022; 143:3163-3172.

Abstract
INTRODUCTION To date, there is no consensus on the optimal surgical strategy for the treatment of posterolateral tibial plateau fracture (PLF). This study introduced a novel, simple technique for treating PLF with a lateral locking plate plus antero-posterior lag screws (LPpLS). METHODS We conducted a retrospective case series of 42 patients (Female/Male 19/23) with PLF treated with LPpLS between 1 July 2016 and 30 June 2019. Several pre- and postoperative outcomes were recorded, including operative time, intraoperative blood loss, CT findings, HSS, and ROM. For biomechanical studies, seventy synthetic tibiae with a simulated posterolateral split fracture were divided into seven groups. The biomechanical evaluation included displacement measurement at axial compression and fatigue testing. RESULTS Forty-two eligible patients were followed up for an average of 18 months (range 14-21 months). Postoperative radiographs and CT showed good positioning of plates and screws, no fracture fragment loss, and normal articular surfaces in all 42 cases. The biomechanical study showed that the axial stiffness of LPpLS was in the same fashion as the posterior buttress plate and better than the other fixation methods (P < 0.05). Additionally, the LPpLS group had a smaller displacement of fracture fragments along the X-axis (medial to lateral direction) than the BP group (P < 0.01). CONCLUSIONS The LPpLS technique could implement good reconstruction of the PLF, showing satisfactory therapeutic effect. The biomechanical evaluation demonstrated that the LPpLS had better stability in three-dimensional directions for PLF than other fixation strategies.

Abstract
High-energy fractures of the proximal tibia with extensive fragmentation of the posterolateral (PL) quadrant of the tibial plateau are challenging to manage. Herein, we present a review of the literature on the patterns and options of approach and fixation of the PL fragment of the tibial plateau to optimize the treatment of this specific injury pattern. We searched PubMed (1980-May 2020) to identify and summarize the most relevant articles evaluating both the morphology and treatment recommendations, including the choice of approach and fixation strategy, for the PL tibial plateau fracture. We found PL fragment can present in several patterns as a pure split, split depression, contained pure depression, and noncontained depression (rim crush), which are mostly determined by the position of the knee and the force magnitude applied during the course of the accident. Based on previous concepts described by Schatzker and Kfuri, we suggest a simplified treatment algorithm highlighting the two concepts (buttressing and containment) used for plating the PL tibial plateau fragments. Based on the available current evidence, we propose an algorithm for these two morphological types of PL tibial plateau fracture. Shear-type fractures need buttressing (the "rule of thumb"), whereas noncontained peripheral rim-type fractures need peripheral repair and containment. Contained pure depression fractures are not frequent and need percutaneous-assisted elevation and subchondral rafting, either controlled by fluoroscopy or arthroscopically. It is believed that such an approach would simplify their assessment and preoperative planning and would assist the clinicians to appreciate and manage more consistently these complex injuries.

A proposal of a new algorithm for decision-making approaches in open reduction and internal fixation of complex tibial plateau fractures - SOTA algorithm (Spanish Orthopaedic Trauma Association). Injury 2021; 52 Suppl 4:S87-S98. [PMID: 34011441 DOI: 10.1016/j.injury.2021.03.064] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 03/05/2021] [Accepted: 03/09/2021] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The correct choice of surgical approaches in complex tibial plateau fractures is essential to achieve adequate reduction and fixation. Detailed fracture morphology and direction of columns displacement, that we have named the Main Deformity Direction (MDD), may aid in selecting the optimal surgical strategy. In this article we present a new algorithm based on MDD and column concepts. The aim of this study was to evaluate the outcomes of a group of tibial plateau fractures treated according to this algorithm. The secondary aim was to evaluate the incidence of the different MDD in our multicolumnar subgroup. PATIENTS AND METHODS Excluding isolated lateral one-column fractures, open fractures and patients not treated following this algorithm, 72 patients with tibial plateau fractures surgically treated with open reduction and internal fixation were collected retrospectively, from three trauma centers, from January 2015 to April 2019. Radiological assessment was performed to establish the columns involved and the MDD. Quality and maintenance of reduction and alignment, complications and functional outcomes were assessed. RESULTS Initial fracture analysis was performed in 72 patients (8 one-column, 35 two-column and 29 multicolumnar fractures). In the multicolumnar group, the posteromedial MDD was the most frequent pattern (17 of 29 patients). Four patients were excluded due to loss of follow-up, resulting 68 patients for final outcome analysis (7 one-column, 34 two-column and 27 multicolumnar). The average follow-up was 18 months (range: 6-52). Excellent/good outcomes were obtained in all one-column, 31 of 34 two-column and 25 of 27 multicolumnar fractures. Incomplete reduction was present in three patients. As complications, we had two loss of reduction, one conversion to knee arthroplasty, one nonunion and one deep infection. No patient presented neurological or vascular problems, knee instability or extension deficit. CONCLUSION Satisfactory results have been obtained following the principles of our algorithm. In addition to the anatomical involvement of columns and segments, we believe that identifying the Main Deformity Direction (MDD) provides useful information for decision-making, especially in multicolumnar fractures. The most frequent MDD in our multicolumnar subgroup was the posteromedial MDD, but more than one-third presented a different MDD, requiring different surgical strategies.

Abstract
Management of posterior tibial plateau fractures has gained much interest over the past few years. Fracture morphology, trauma mechanism, and soft-tissue injury have been identified as the key factors determining the treatment strategy and outcome. We provide a rationale for the operative management of posterior tibial plateau fractures by discussing the interplay between fracture morphology, trauma mechanism, and soft-tissue injury. The trauma mechanism has proven to be an important tool, not only to understand fracture morphology, but also to assess concomitant soft-tissue (i.e. ligamentous) injury. Subsequently, soft-tissue injury might play a role in future classification and diagnostic work-up of tibial plateau fractures, particularly in fractures with posterior involvement. Plate osteosynthesis using a posterior approach is safe and should be considered routinely in coronal fractures of the posterior tibial plateau, as illustrated.

Abstract
BACKGROUND Comminuted lateral tibial plateau fractures pose a challenge to surgeons, with non-anatomical reductions in 70-89%, involving the posterolateral articular surface. The purpose of this study was to examine the posterolateral joint visibility, using lateral extended approaches, such as the lateral femoral epicondyle osteotomy or the fibula osteotomy. Further, the study aimed to compare the combined osteotomy of the femoral footprints of the lateral collateral ligament (LCL) and popliteus tendon (PLT) to the isolated osteotomy of the femoral LCL footprint or the fibula osteotomy, in terms of posterolateral joint accessibility. METHODS Extended lateral (femoral or fibular LCL osteotomy) and posterolateral (additional femoral osteotomy of the PLT tendon) approaches were performed on twelve human cadaver knees. After preparation of each surgical approach, the visible articular surface was marked with diathermy. The tibial plateau was disarticulated and the markings were measured digitally with open-source processing software. Differences in mean values were tested with a paired t-test (p ≤ 0.05). RESULTS The greatest articular exposure was achieved with the fibula osteotomy (1011.52 ± 227.05 mm2 [86.64 ± 4.84%] compared to the combined osteotomy of LCL and PLT (p = 0.036) or LCL alone (p<0.001). The lateral femoral epicondyle osteotomy of the LCL including the PLT (937.45 ± 237.84 mm2 [80.29 ± 8.25%]) exposed a significantly larger articular surface of the lateral tibial plateau than without the PLT (755.71 ± 183.06 mm2 [64.73 ± 6.51%], p < 0.001). CONCLUSION In direct comparison, the fibula osteotomy provides the largest articular visualization, however at cost of a considerably larger soft tissue damage. While the lateral femoral epicondyle osteotomy of LCL and PLT increases lateral articular visualization, it omits the risk of neurovascular or posterolateral soft tissue damage and therefore represents an important extended approach to treat comminuted lateral plateau fractures.

Abstract
Background Several approaches of fracture reduction and fixation are employed in complex tibial plateau fractures. However, there is a lack of consensus regarding reduction and fixation for fractures to the posterolateral part of the tibial plateau. Hypothesis The combined direct posterior split-gastrocnemius approach may be a choice of the posterior part involved comminuted tibial plateau fractures. Patients and methods We review cases of 216 patients with tibial plateau fracture and subsequent operation from 2012/1/1 to 2017/1/1. Fifty-six cases involved posterolateral plateau damage. For these 56 patients, we use anteromedial and direct posterior split-gastrocnemius approaches or anterolateral and direct posterior split-gastrocnemius approaches to fix the posterolateral and medial or lateral segments. Results From the radiography films, all patients (56/56) achieved a good reduction of the articular surface after surgery (31 patients were anatomic reduction, 25 patients were acceptable reduction). After 12 months follow up, only 2 patients showed poor reduction and no significant difference between <3 days after surgery and 12 months follow up. All patients acquired good knee functions at 12 months’ time-point of the fracture surgery. These patients have less pain and other related symptoms in daily living according to the Knee Injury and Osteoarthritis Scores. Conclusion The direct posterior split-gastrocnemius approach provides efficient and less invasive access to the posterolateral tibial plateau, which is suitable for direct reduction and rigid fixation to the fragments of posterolateral tibial fractures. It is a valuable choice when mapping a surgical approach to tibial plateau fracture reduction involving the posterior tibial plateau and its implementation may offer better post-operative functionality relative to alternative approaches.

Abstract
INTRODUCTION Updated three column fixation of tibial plateau fractures (TPFs) arouse the importance of posterior column articular reduction. Complex TPFs with posterolateral (PL) articular injury is difficult to manage. We presented a strategy of combined positions and approaches to treat these injuries. Surgical technique was described and outcome of these were reported. MATERIALS AND METHODS From 2014 Jan to 2016 Dec, there were 132 patients of TPFs treated in our institute. Preoperative evaluation included plain films and 2D/3D CT scan to evaluate the involvement of articular surface and associated columns. Inclusion criteria were three column TPFs with PL corner injury. We put patients in prone position first with reverse L incision to manage PL articular impaction and posteromedial (PM) fractures. Then we repositioned the patients in supine to treat anterolateral fixation. Postoperative radiographic analysis, physical examination findings, and patient reported outcome scores from the Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire were recorded. RESULTS Patient demographic information was retrospectively reviewed with a mean follow-up time of 34.4 months (range 24-48 months). The average time to union was 5.2 months (range 4-8months). 13/16 (81%) of patients had satisfactory articular reduction by plain films (less than 2 mm articular step off). All patients demonstrated healed without secondary displacement or infection. All patients demonstrated satisfactory coronal (medial proximal tibia angle 84.68 degrees) and sagittal alignment (posterior proximal tibia angle 84.75 degrees). Condylar width averaged 3.93 mm. 3/16 (19%) of cases required posterolateral columnar plating in addition to posteromedial columnar plating. The knee range of motion averaged 115 degrees (ranged from 0 degrees of extension to140 degrees flexion). The average KOOS score was 83/100 (range 76-90). 3 patients in the series developed a surgical site superficial infection and resolved after debridement and oral antibiotics use. No patient eventually received total knee arthroplasty at the last follow up. CONCLUSIONS Our strategy provides an effective method to treat three column tibial plateau fractures with PL articular injury.

Abstract
INTRODUCTION The correct choice of a fracture-specific surgical approach with an articular accessibility in complex tibial plateau fractures to facilitate durable fracture fixation of the anatomic articular reconstruction is under debate, as the most important risk factor for malreduction in complex tibial plateau fractures is an impaired visualization of the articular surface. MATERIALS AND METHODS Six established surgical approaches were simulated on 12 cadaver knees. The visible articular surface was labeled with an electrocautery device for each approach and subsequently analyzed with ImageJ. Areas of each hemiplateau were compared using the Student's t test. RESULTS In the lateral tibial plateau, the dorsal 19.0 ± 5.8% of the articular surface could be exposed via the postero-lateral approach. Via the antero-lateral arthrotomy, 36.6 ± 9.4% of the anterior articular surface was visible. The additional osteotomy of the lateral femoral epicondyle significantly increased the exposure to 65.6 ± 7.7% (p < 0.001). In the medial tibial plateau, the osteotomy of the medial femoral epicondyle significantly improved visualization of the medial articular surface (62.3 ± 8.6%) compared to the postero-medial approach (14.0 ± 7.3%) and the antero-medial approach (36.9 ± 9.2%) of the articular (p < 0.001). CONCLUSIONS Visualization of the tibial articular surface is limited through specific surgical approaches. Extension by osteotomy of the femoral epicondyle led to a significant improvement in the articular exposure without, however, obtaining sufficient visibility of the posterior joint segments, which should be included in the preoperative strategy. The proposed surgical approach-specific map of the tibial plateau may constitute an important instrument in the toolbox of an experienced surgeon to treat complex tibial plateau fractures at the highest level.

Abstract
INTRODUCTION Tibial plateau fractures occur frequently during downhill skiing. There is a lack of information about the outcome and development of posttraumatic osteoarthritis after internal fixation of such fractures at long-term follow-up in skiers. MATERIALS AND METHODS A population of 83 skiers was followed up in a case series after internal fixation of intra-articular tibial plateau fractures AO-OTA 41 B1-B3 and C1-C3. Functional outcomes Visual Analog Scale, Tegner Activity Scale, Modified Lysholm Score, Hospital for Special Surgery (HSS) Knee Score and X-ray images of the affected knees (preoperative, postoperative and at time of follow-up) were obtained. Radiological evaluation focused on severity of osteoarthritis according to the Kellgren and Lawrence score of the lateral, medial and retropatellar knee compartments separately. Subgroup analyses for fracture type and age were performed separately. RESULTS Patients age was 49.8 ± 12.9 years (range 19-74 years) at the time of surgery, with a mean follow-up period of 10.3 ± 1.9 years (range 6-14 years). All tibial plateau fractures affected the lateral compartment, while the medial compartment was affected in addition as part of bicondylar fractures in two cases. Both the Tegener Activity Scale and Lysholm Score decreased significantly during the follow-up period and their median values dropped from 6 (range 3-7) to 5 (range 2-7) and from 100 (range 90-100) to 95 (range 58-100), respectively (both p < .01). The median clinical knee function at the time of follow-up revealed an HSS Knee Score of 96.5 points (range 74-100). Among the whole patient population, the radiological evaluation at follow-up revealed a significantly higher grade of osteoarthritis in all compartments of the knee joint compared to the time of the operation (p < .01). The grade of osteoarthritis in the lateral compartment was significantly higher than that in the medial and retropatellar compartments (p < .01). CONCLUSIONS In addition to physiologic aging, progression of radiologic signs of osteoarthritis following internal fixation of intra-articular tibial plateau fractures in an athletic population of skiers is most severe in the lateral knee compartment corresponding to fracture location. However, the long-term functional outcomes seem to be very satisfactory.

Abstract
INTRODUCTION The three-column concept has been proposed as tool in surgical decision-making for treating tibial plateau fractures. Recent studies have underscored the negative effect of posterior column tibial plateau fractures on clinical outcome. The purpose of this study was to assess the value of the three-column concept and posterior plating in posterior column fractures. We hypothesized that treating patients according to the three-column concept improves functional outcome. METHODS 111 consecutive tibial plateau fractures, treated between January 2009 and December 2016, with at least a posterior column fracture were included. Relevant demographic and treatment variables were studied. Applied treatment was retrospectively evaluated according to the three-column concept. Patient reported outcome was assessed using the Knee injury and Osteoarthritis Outcome Score (KOOS). RESULTS Median follow-up was 43.1 months (IQR 29.0-63.3) with a response rate of 80.2%. Outcome scores were markedly lower compared to the general population. 22.5% patients were treated according to the three-column concept and 27% was treated with posterior plating. Predominantly combined fractures of posterior and lateral columns were treated without fixation of the posterior column. Neither treatment according to the three-column concept and/or with posterior plating was found to significantly influence outcome. CONCLUSIONS The outcome of posterior column fractures was equal, regardless of whether these fractures were treated or not. This indicates that the three-column concept seems insufficient and gives rise to further debate on surgical strategies of posterior column fractures. The implementation of trauma mechanism-based fracture morphology in the three-column concept might be important to consummate the three-column concept as guiding tool. LEVEL OF EVIDENCE 3.

Abstract
OBJECTIVE The aim of the surgical treatment of intra-articular bicondylar tibial plateau fractures is the anatomical reconstruction and direct biomechanical optimal fixation of the fractured articular surface and the leg axis, taking the frequently associated soft tissue damage into account. INDICATIONS This article presents a cadaver model of a simulated complex bicondylar tibial plateau fracture 41C3 according to the AO classification with fracture involvement of all 10 segments and indications for surgery due to a posteromedial shearing fracture and lateral articular destruction with posterolaterocentral impaction. CONTRAINDICATIONS Pronounced soft tissue damage with acute or incompletely healed infections in the area of the surgical approach. SURGICAL TECHNIQUE In the presented video of the operation, which is available online, the direct treatment of an intra-articular complex tibial plateau fracture from dorsal in a prone position is shown in detail: posterolateral ca. 13 cm long skin incision immediately above the fibular head with subsequent gentle preparation of the peroneal nerve at the medial border of the biceps femoris muscle. Retraction of the lateral head of the gastrocnemius muscle medially. Proximal detachment of the soleus muscle from the fibular head and retraction of the popliteus muscle medially. Horizontal capsule incision for fracture visualization. Opening of the lateral window ventral to the lateral collateral ligament. If necessary, osteotomy of the lateral femoral epicondyle for improved posterolaterocentral fracture visualization. Angular stable osteosynthetic fixation. Posteromedial approach medial to the medial gastrocnemius head. Retraction of the medial head of the gastrocnemius muscle laterally, horizontal capsular incision with sparing of the semimembranosus muscle medially and posterior cruciate ligaments laterally, fracture reduction, fixation with posteromedial support plate, image converter control, wound closure. FOLLOW-UP Postoperative cooling and elevation of the operated limb. Depending on the fracture 6-10 weeks partial loading of maximum 20 kg. Prior to full load bearing clinical radiological follow-up checks to determine the bony consolidation and material positioning. RESULTS This is an established and safe delivery strategy for complex fracture patterns with dorsally running fractures. The risk of intraoperative malreduction is low. Postoperative reduction losses depend on fracture, operation and especially patient-specific characteristics.
