Methods From January 2007 to December 2009, 56 patients with complex tibial plateau fractures underwent open reduction and internal fixation. The patients included 37 males and 19 females with the age of 19-76 years old (average 45.6 years old). The Schatzker type of the fractures were type Ⅳ in 12 patients, type Ⅴ in 26, and type Ⅵ in 18. The injuries included meniscus injury in 20 patients, injury of lateral collateral ligament of knee in 9, injury of lateral collateral ligament in 8, and cruciate ligaments injury in 4. The time duration between the injury and the surgery was 7-14 days (average 9 days). Results After the surgery, the incision healed at I stage in 53 patients. The incision was superficially infected 3 days after surgery in 2 patients, and the Necrosis of skin around the incision and revealed steel plate were found 7 days after surgery in 1 patient; the injuries was healed after corresponding treatment. All of the patients were followed up with the average follow-up period of 14-49 months (average 19 months). The fractures healed 4-8 weeks (average 6 weeks) after the surgery. Knee joint ankylosis was found in one, traumatic arthritis was found in two, and heterotopic ossification was found in one; the injuries was healed after corresponding treatment. Twelve months after the surgery, the therapeutic effect according to HSS criteria indicated that the score was excellent in 43, good in 5, generally in 4 and poor in 4; with a fine rate of 85.7%. Conclusion Appropriate conditions of the soft tissue, good surgical opportunity, a appropriate fixation, improved surgical technique and effective postoperative functional training are the key points of surgical treatment for complex tibial plateau fractures.
ObjectiveTo introduce the surgery method to reset and fix tibial plateau fracture without opening joint capsule, and evaluate the safety and effectiveness of this method. MethodsBetween July 2011 and July 2013, 51 patients with tibial plateau fracture accorded with the inclusion criteria were included. All of 51 patients, 17 cases underwent open reduction and internal fixation without opening joint capsule in trial group, and 34 cases underwent traditional surgery method in control group. There was no significant difference in gender, age, cause of injury, time from injury to admission, side of injury, and types of fracture between 2 groups (P>0.05). The operation time, intraoperative blood loss, incision length, incision heal ing, and fracture healing were compared between 2 groups. The tibial-femoral angle and collapse of joint surface were measured on X-ray film. At last follow-up, joint function was evaluated with Hospital for Special Surgery (HSS) knee function scale. ResultsThe intraoperative blood loss in trial group was significantly less than that in control group (P<0.05). The incision length in trial group was significantly shorter than that in control group (P<0.05). Difference was not significant in operation time and the rate of incision heal ing between 2 groups (P>0.05). The patients were followed up 12-30 months (mean, 20.4 months) in trial group and 12-31 months (mean, 18.2 months) in control group. X-ray films indicated that all cases in 2 groups obtained fracture heal ing; there was no significant difference in the fracture healing time between 2 groups (t=1.382, P=0.173). On X-ray films, difference was not significant in tibial-femoral angle and collapse of joint surface between 2 groups (P>0.05). HSS score of the knee in trial group was significantly higher than that of control group (t=3.161, P=0.003). ConclusionIt can reduce the intraoperative blood loss and shorten the incision length to use open reduction and internal fixation without opening joint capsule for tibial plateau fracture. Traction of joint capsule is helpful in the reduction and good recovery of joint surface collapse. In addition, the surgery without opening joint capsule can avoid joint stiffness and obtain better joint function.

Objective To investigate the cl inical effect of minimally invasive internal fixation percutaneous plate osteosynthesis (MIPPO) assisted by arthroscopy on tibial plateau fractures. Methods From September 2005 to December 2007, 29 patients with tibial plateau fracture underwent arthroscopy-assisted MIPPO, including 18 males and 11 females aged18-59 years old (average 34.7 years old). There were 8 cases of type II, 10 of type III, 5 of type IV, 3 of type V, and 3 of type VI according to Schatzker classification system. The fracture was combined with meniscus injury in 13 cases, anterior cruciate l igament injury in 4 cases, and medial collateral l igament injury in 3 cases. The time from injury to operation was 2-10 days. Firstly, the combined injury was treated under arthroscopy. Then, reduction of tibial plateau fractures was performed, bone grafting was conducted in the area of bone defect, and internal fixation using strut plates was performed after establ ishing subcutaneous tunnel via minimally invasion. Early rehabil itation activities were carried out for each patient 1 day after operation. Results No early compl ications such as poor heal ing of incisions, infections, and osteofascial compartment syndrome occurred. Over the follow-up period of 12-39 months (average 24 months), there was no failure of internal fixation, traumatic knee osteoarthritis, and inversion and eversion of the knee. The fractures healed within 3-4.5 months (average 3.5 months). The cl inical effect was excellent in 23 cases, good in 4 cases, and fair in 2 cases according to Lysholm knee rating system, and the excellent and good rate was 93.1%. Conclusion Arthroscopy-assisted MIPPO is a safe and effective way of managing tibial plateau fractures due to its features of minimal invasion, earl ier recovery, fewer compl ications, and simultaneous treatment of associated intra-articular injuries.
Objective To investigate the biomechanics of a novel injectable calcium phosphate cement (CPC) composited by poly (lactic-co-glycolic acid) (PLGA) combined with double-screw fixation in repairing Schatzker II type tibial plateau fracture, so as to provide the mechanical basis for the clinical minimally invasive treatment. Methods Ten matched pairs of proximal tibia specimens were harvested from 10 elderly cadavers to prepare Schatzker II type tibial plateau fracture model. Fracture was fixed by forcing injection of CPC (experimental group) or autologous cancellous bone (control group) combined with double-screw fixation. The samples underwent axial compression on MTS 858 material testing machine to measure the load-displacement, the maximum load, and compressive stiffness. Results The novel CPC had good injectable property at room temperature, which could fill in bone defect fully and permeated into the surrounding cancellous bone. The average bone mineral density of tibial metaphysis was (0.639 ± 0.081) g/cm2 in the experimental group and (0.668 ± 0.083) g/ cm2 in the control group, showing no significant difference (t=1.012, P=0.331). The maximum load in the experimental group [(4 101 ± 813) N] was significantly higher than that in the control group [(692 ± 138) N] (t=3.932, P=0.001). The compressive stiffness was (1 363 ± 362) N/mm in the experimental group and was (223 ± 54) N/mm in the control group, showing significant difference (t=3.023, P=0.013). Conclusion The novel CPC can effectively restore the biomechanical properties of tibilal plateau in repairing Schatzker II type tibial plateau fracture by means of forcing injection combining with double-screw fixation. It could be used as an effective bone substitute in the clinical application.
Objective To investigate the effectiveness of the reverse traction device in the preoperative treatment of high-energy tibial plateau fractures. Methods A retrospective study was conducted to analyze the clinical data of 33 patients with high-energy tibial plateau fractures who met the selection criteria between December 2020 and December 2023. All patients were treated by open reduction and internal fixation. According to the preoperative traction method, they were divided into the observation group (16 cases, treated with a reverse traction device on the day of admission) and the control group (17 cases, treated with heel traction on the day of admission). There was no significant difference in baseline data such as gender, age, body mass index, affected side, cause of injury, fracture Schatzker classification between the two groups (P>0.05). Preoperative waiting time, preoperative related complications (nail channel loosening, nail channel oozing, nail channel infection, soft tissue necrosis, soft tissue infection, deep vein thrombosis of the lower extremity, etc.), operation time, and total hospitalization time were recorded and compared between the two groups. On the 4th day after traction, visual analogue scale (VAS) score was used to evaluate the pain relief of the patients, the swelling value of the affected limb was measured, and the Immobilization Comfort Questionnaire (ICQ) score was used to evaluate the perioperative hospital comfort of the patients. Results Both groups of patients completed the operation successfully, and the operation time, total hospitalization time, and preoperative waiting time of the observation group were significantly less than those of the control group (P<0.05). There was no preoperative related complications in the observation group; in the control group, 3 patients had nail channel loosening and oozing, and 2 cases had the deep vein thrombosis of the lower extremity; the difference in the incidence of complication between the two groups was significant (P<0.05). On the 4th day after traction, the ICQ score, VAS score, and limb swelling value of the observation group were significantly better than those of the control group (P<0.05). X-ray films showed that the tibial plateau fracture separation and lower limb alignment recovered after calcaneal traction in the control group, but not as obvious as in the observation group. The fracture gap in the observation group significantly reduced, the tibial plateau alignment was good, and the lateral angulation deformity was corrected. Conclusion The use of reverse traction treatment in patients with high-energy tibial plateau fractures on admission can accelerate the swelling around the soft tissues to subside, reduce patients’ pain, shorten the preoperative waiting time, improve the patients’ preoperative quality of life, and contribute to the shortening of the operation time, with a good effectiveness.
ObjectiveTo evaluate the effectiveness and safty of posterior popliteal fossa S-shaped incision with double-window approach for the treatment of posterior column of tibial plateau fractures.MethodsA retrospective analysis was made on the clinical data of 13 patients with complex tibial plateau fractures involving both posteromedial and posterolateral columns between May 2015 and July 2017. There were 9 males and 4 females, aged 33-64 years (mean, 46.5 years). The causes of injury included traffic accident in 5 cases, falling from height in 2 cases, falling from electric bicycle in 4 cases, and falling because of skiing in 2 cases. The preoperative range of motion of the affected knees was (35.1±9.2)°. The time from injury to surgery was 7-19 days (mean, 13.3 days). All patients underwent a posterior popliteal fossa S-shaped incision through the window of medial heads of gastrocnemius muscle (medial window) and the window between medial and lateral head of gastrocnemius muscle (popliteal fossa window) approaches. After a good visual control of fracture reduction, both posteromedial and posterolateral columns of tibial plateau fractures were fixed with buttress plate respectively. Bone union, limb alignment, articular surface, and range of motion were estimated after operation. The American Hospital for Special Surgery (HSS) score was used to evaluate functional outcomes of knees.ResultsAfter operation, 1 patient had fat liquefaction and dehiscence of incision, which healed after expanding the wound; the other patients’ incisions healed by first intention, and no vascular or nerve injury occurred during operation. All the 13 patients were followed up 12-18 months (mean, 16 months). The X-ray films showed that all patients obtained good fracture unions, the fracture healing time was 14-22 weeks (mean, 18 weeks). At 12 months after operation, the articular surface was smooth without collapse, and the knee range of motion was (109.5±13.6)°, showing significant difference when compared with preoperative value (t=18.879, P=0.000). No complication of infection, re-displacement of fracture, or secondary varus/valgus deformity was observed during follow-up. The HSS score was 82-96 (mean, 89.6) at 12 months after operation, with the result of excellent in 10 cases and good in 3 cases.ConclusionThe posterior column fracture of tibial plateau involving both posteromedial and posterolateral columns treated by double-window approach through posterior popliteal fossa S-shaped incision is safe and effective, with satisfactory results and good recovery of knee joint function.
