Purpose This study compared the outcomes of minimally invasive plate osteosynthesis and antegrade intramedullary nailing for low-energy fracture of the distal femoral shaft. Materials and Methods A study was conducted on 30 patients who underwent surgery for low-energy fractures of the distal femoral shaft between January 2016 and April 2022. The study compared 15patients who underwent minimally invasive plate osteosynthesis (Group P) with 15 patients who underwent recon-type antegrade intramedullary nailing (Group N). We evaluated intraoperative blood loss, operative time, C-arm exposure time, bone density, final union status, anatomical reduction, and clinical evaluation. The complications were also examined, and statistical analysis was conducted to compare the two groups. Results The blood loss, surgery time, and C-arm time were similar in the two groups. The radiographic assessments and clinical evaluations were also similar in the two groups. The clinical results showed no difference between the groups. Group N had one case of nonunion and one case of delayed union, while Group P had one case of nonunion and one case of peri-prosthetic fracture. Conclusion Antegrade intramedullary nailing of the recon-type demonstrated comparable results to minimally invasive plate osteosynthesis. Hence, antegrade intramedullary nailing of the recon-type, which enhances stability by fixing the entire femur and providing additional fixation in the distal portion, is deemed appropriate for treating distal femoral shaft fractures.
Purpose This study examined the outcomes of additional medial locking plate fixation and autogenous bone grafting in the treatment of nonunions that occurred after initial fixation for distal femoral fractures using lateral locking plates. Materials and Methods The study involved eleven patients who initially underwent minimally invasive lateral locking plate fixation for distal femoral fractures between January 2008 and December 2020. The initial procedure was followed by additional medial locking plate fixation and autogenous bone grafting for clinically and radiographically confirmed nonunions, while leaving the stable lateral locking plate in situ. A clinical evaluation of the bone union time, knee joint range of motion, visual analog scale (VAS) pain scores, presence of postoperative complications, and functional evaluations using the lower extremity functional scale (LEFS) were performed. Results In all cases, bone union was achieved in an average of 6.1 months after the secondary surgery. The range of knee joint motion, weight-bearing ability, and VAS and LEFS scores improved at the final follow-up compared to the preoperative conditions. All patients could walk without walking assistive devices and did not experience pain at the fracture site. On the other hand, three patients complained of pain in the lateral knee joint caused by irritation by the lateral locking plate; hence, lateral hardware removal was performed. One patient complained of mild paresthesia at the anteromedial incision site.
Severe complications, such as deep infection or metal failure, were not observed. Conclusion For nonunion with stable lateral locking plates after minimally invasive lateral locking plate fixation of distal femur fractures, additional medial locking plate fixation and autogenous bone grafting, while leaving the lateral locking plate intact, can achieve successful bone union.
PURPOSE To evaluate the efficacy of surgical treatment through retrospective comparison of minimally invasive percutaneous plate osteosynthesis (MIPPO) vs open plate fixation in the treatment of the distal femur fractures. MATERIALS AND METHODS Thirty-one patients with distal femur fractures from January 2002 to December 2010 were divided into two groups depending on the surgical method. Minimum follow up was 12 months. Group A consisted of 17 patients treated with MIPPO, and group B was comprised of 14 patients treated with open plate fixation. Clinical outcomes including operation time, transfusion rate, rehabilitation, range of motion, and interval change of postoperative C-reactive protein (CRP) were evaluated to assess postoperative inflammatory reaction, postoperative complications and clinical results with the use of Sanders criteria. RESULTS The operative time was 86/135 min and transfusion volume was 0.8/1.9 unit respectively. The postoperative 3-day and 7-day CRP were 7.4/1.5 mg% in group A and 10.3/2.4 mg% in group B, showing more minimal tissue injury and early recovery in group A. There were no significant differences in clinical results by Sanders criteria in both groups. CONCLUSION Both MIPPO and open plate fixation for the treatment of distal femur fractures showed comparably good results. However, the MIPPO technique is superior to group B in view of minimal tissue injury and operation time and was proven to lessen the transfusion rate.

PURPOSE To compare results of minimally invasive plate osteosynthesis using a locking compression plate and a periarticular locking plate in distal femur fractures. MATERIALS AND METHODS We retrospectively reviewed 31 consecutive femoral fractures who treated by minimally invasive plate osteosynthesis from April 2006 to May 2009. Sixteen patients were treated using a locking compression plate (group A) and 15 patients were treated using a periarticular locking plate (group B). RESULTS The mean operation time was 78 minutes and 76 minutes (p=0.273), and the mean radiation exposure time was 1.9 minutes and 2.3 minutes (p=0.001) in the group A and B, respectively. The plate bending during operation was performed in 4 cases of group A. The knee range of motion was 117.5degrees and 118.2degrees (p=0.825), and the Lysholm score was 81.3 and 81.8 (p=0.723) in the group A and B, respectively. Schazker criteria showed more than good grade in 93.8% of group A and in 93.3% of group B (p=1.0). CONCLUSION No significant differences in clinical results were observed between the two groups. However, a lower anatomical compliance was showed in the locking compression plate, and a higher risk of radiation exposure was showed in the periarticular locking plate.

PURPOSE To report the clinical outcome of polyaxial locking plate (Noncontact bridging (NCB) plate (Zimmer, Warsaw, Indiana)) for the treatment of distal femur fracture with minimal invasive percutaneous periosteal osteosynthsis (MIPPO) technique. MATERIALS AND METHODS Between February 2008 to April 2010, twenty six patients (11 men, 15 women), twenty eight cases diagnosed as distal femoral fractures are enrolled in this retrospective study. The mean age of the patients was 63 years (34 to 85) and the mean follow-up was 20.3 months (12 to 32). According to the AO/ASIF classification, 15 fractures were type A, 1 type B and 9 type C. And there were 3 periprsthetic fractures around knee. The analysis of the clinical and radiologic outcome were performed by Sanders functional evaluation scale and radiologic follow up after operation, respectively. RESULTS Among 28 cases, 25 cases united without additional operation. According to Sanders functional evaluation scale, there were 11 excellent, 9 good, 4 fair, 2 poor. As complications, there were 1 knee stiffness, 1 delayed union, 1 implant failure with refracture, 1 implant loosening. Three patients except one knee stiffness, underwent a second LISS plating using NCB plate and and bone grafting, resulting in a satisfactory final outcome. CONCLUSION Internal fixation using polyaxial locking plate with MIPO technique may be one of the most effective methods for the treatment of distal femoral fractures.

PURPOSE To analyze the surgical results of AO type C distal femoral fractures using locking compression plate. MATERIALS AND METHODS From February 2006 to June 2008, 14 patients 15 cases were included. Injury mechanisms, combined injuries, radiologic and clinical results and postoperative complications were analyzed. RESULTS The mean age was 59.6 (30~77) years. The mean follow up period was 25 (12~40) months. AO types were 3 of C1, 5 of C2 and 7 of C3. Injury mechanisms were 9 of traffic accident, 5 of slip down and 1 of fall from a height. Four cases were combined with other extremity injuries or fractures. The mean radiologic union was obtained at postoperative 15 (13~20) weeks. The mean Neer's functional score was 74.2 (58~97); 3 of excellent, 5 of satisfactory and 7 of unsatisfactory. Postoperative complications were 2 of infection and 1 of nonunion. There were no mechanical failures or fixation loss with locking compression plate at the final follow up. CONCLUSION Internal fixation using locking compression plate for AO type C distal femoral fractures provided excellent fixations. At the final follow up, the clinical results were variable. The affecting factors on the final results seemed to be joint congruencies after anatomical reduction and active rehabilitation.

PURPOSE To evaluate the clinical and radiologic results of minimally invasive plate osteosynthesis, We analyzed the cases of distal femoral fracture treated with this newly developed surgical technique. MATERIALS AND METHODS We reviewed 12 cases of distal femoral fracture which had been treated with minimally invasive plate osteosynthesis and each patients had been followed up for a minimum twelve months. Post-operative function was evaluated with checking the range of motion of knee joint and Knee Society Score. Union period and post-operative alignment was measured on radiograph. RESULTS In all cases, bony union was obtained in average fifteen weeks after operation without bone graft. The arc of motion of knee joint which was checked at the last follow up was 123.75 degrees on average. According to Knee Society Score, there were 9 excellent, 1 fair and 1 poor results. The post-operative complications were malunion in 1 case, soft tissue infection in 1 case and joint stiffness in 1 case. CONCLUSION The treatment of distal femoral fracture with minimally invasive plate osteosynthesis is one of the good surgical options for clinically preferable results with high union rate without bone graft and early joint motion.

PURPOSE To evaluate the result of comparative study about the cases in the fracture of the distal femur treated with plate and screw, dynamic condylar screw, blade plate, retrograde intramedullary nail and external fixator. MATERIALS AND METHODS The AO classification system was used. 84 cases who were preformed operation during the period from March 1996 to May 2002, were included in this study. The mean duration of follow-up was 25 months. According to Sachatzker criteria, we classified the following results to excellent, good, fair and poor. RESULTS Type A were excellent or good result when treated with plate and screw, dynamic condylar screw and retrograde intramedullary nail. Type B were excellent or good result when treated with cannulated screw. Type C were excellent or good result when treated with plate and screw and blade plate. CONCLUSION We conclude that the most important thing in operation is firmly internal fixation and to obtain this, accurately anatomical reduction and the choice of suitable instrument for the type of the fracture are needed. cannulated screw. Type C were excellent or good result when treated with plate and screw and blade plate.

PURPOSE To evaluate the usefulness of early range of motion exercise by using 90degrees knee flexion splint after open reduction and internal fixation in fracture of distal femur. MATERIALS AND METHODS We reviewed twenty-six cases of distal femur fractures which were treated with open reduction and internal fixation from February 2002 to November 2003. One group (group A) were treated by using 30degrees knee flexion splint, the other group (group B) were treated by using 90degrees flexion and full extension splint alternativley by post-operative 1 week. The follow up period was minimally 12 months. The range of motion and Schatzker and Lambert criteria were evaluated. RESULTS The mean period to gain 90degrees knee flexion was 11.4 (7~14) weeks in group A, and 6.6 (3~8) weeks in group B. Mean range of motion was 94.7degrees (average flexion contracture 9.5degrees ) in A group and 108.7degrees (average flexion contracture 6.3degrees ) in B group at 12 weeks follow-up. According to Schatzker and Lambert criteria, excellent result was achieved in 10 cases (38%), good result in 13 cases (50%), fair result in 3 cases (12%). CONCLUSION This study demonstrates that alternative splinting at extension and 90degrees flexion contribute to early recovery of range of motion in distal femur fractures treated with internal fixation.

PURPOSE We retrospectively reviewed the outcomes and advantages of minimal invasive plating osteosynthesis (MIPO) technique as a new treatment of distal femoral fractures. MATERIALS AND METHODS Sixteen supracondylar femoral fractures (15 patients) were treated by MIPO technique and evaluated radiologically and functionally after minimal 1 year follow-up (average; 22 months, range; 13~42 months). There were 9 women and 6 men with a mean age of 46 years old (range 35 to 64 years). Seven fractures were extended into knee joints (AO/OTA type C), and 9 were extraarticular (AO/OTA type A). Five cases were open fractures (type I; 2, type II; 3) according to the Gustilo-Anderson classification. After minimal lateral parapatellar incision and accurate reduction of intra-articular fractures, the supracondylar fractures were fixed by percuatneous plating method without exposure of fracture area. Neer scoring was used for functional evaluation of knee. RESULT At a mean of 17 weeks (range 14 to 22), most fractures united without secondary procedures. One case of nonunion had the procedure of bone graft, but there were no other complications including shortening over 1 cm, mal-alignment over 10 degrees, or deep infections. All the cases had good or excellent knee function, and the average range of knee motion was 120.6 degrees. CONCLUSION MIPO technique is a worthwhile method of managing distal femoral fractures with good unions and functional recovery.

A fractures of the distal femur is an extremely complex fracture with which to deal. Poor bone stock, proximity to the knee joint, and a truncated shape make this area of the femur less suitable for internal fixation than other areas. Ideal care still somewhat controversial. Major complications include nonunion, delayed union, infection, loss of fixation, Joint stiffness and angular deformity, etc.
The authors reviewed postoperative tiblo-femoral angular changes from the twenty six cases of supracondylar and intercondylar fractures of the femur treated operatively from January, 1988 to December, 1991. Fractures of a single condyle were excluded. The fractures were fixed internally with dynamic condylar screw(DCS) in nine cases, anatomic plate in nine, dynamic compression plate(DCP) in six and others in two. During the periods of follow up there noted varus change of 3.7 degrees in average. We reviewed retrospectively these postoperative varus or valgus angular changes with reference to the degree of injury, type of fracture, time elapsed from injury to operation, kind of internal fixation device, initial bone graft and postoperative brace supplement. Less angular changes in the tiblo-femoral angle with better results were noted in cases with lower energy injuries, AO type Al, A2 or Cl fractures, operation within 1 week of injury, internal fixation with DCS, initial bone graft and postoperative corrective brace supplement.
