RATIONALE: High tibial osteotomy (HTO) has been used widely for medial compartment knee osteoarthritis to correct the deformity and relieve symptoms, especially in young patients who are willing to maintain the high activity level. However, the change of bone morphology, ligament imbalance, limb malalignment, and other complications may influence the short-term outcomes of HTO. Some cases may even require conversion to TKA shortly after HTO because of the loss of correction or pain due to accelerated osteoarthritis...

BACKGROUND: Slipped capital femoral epiphysis (SCFE) is the most common hip disorder in children 9-15 years old. This is a population-based study in Sweden presenting the epidemiology for SCFE. METHODS: In a prospective cohort study, we analysed pre- and postoperative radiographs, medical records for all children treated for SCFE in Sweden 2007-2013, demographic data, severity of slip and surgical procedures performed. RESULTS: We identified 379 Swedish children with primary SCFE 2007-2013; 162 girls, median age 11...

This case report outlines some of the challenges as well as limitations in correction of osteoarthritis of the knee in combination with extra-articular deformities,and provides a novel and straightforward surgical solution in overcoming these challenges. We describe the case of a 37-year-old male who suffered from advanced bilateral tri-compartmental knee arthritis due to untreated bloodstream-sourced osteomyelitis after birth. Radiographs and surgery confirmed extremely severe deformities. We performed two different surgical techniques in order to correct extra-articular deformities (one-stage approach of concurrent tibial and femoral osteotomy and total knee arthroplasty on one side, and soft tissue balancing with "pie-crusting technique" plus total knee arthroplasty on the other side), with description of subsequent results at 36-months follow-up...

BACKGROUND: There is a renewed interest in joint preservation surgery, and lateral opening wedge distal femoral osteotomy (DFO), a joint-preserving procedure, has been used to treat symptomatic genu valgum when the deformity originates in the distal femur. QUESTIONS/PURPOSES: This study aimed to measure the accuracy of lateral opening wedge DFO in achieving deformity correction using radiographic parameters. In addition, the ability of lateral opening wedge DFO to improve patient outcomes as measured by Short Form Health Survey (SF-36) scores and American Academy of Orthopedic Surgeons (AAOS) lower limb module (LLM) scores leading to successful joint preservation was assessed...

BACKGROUND: Open wedge high tibial osteotomy (HTO) can influence the tibial slope and thereby the landmarks of currently used patellar height indices. The purpose of this retrospective study was to compare and validate a new femur-referenced patella height measurement method to currently used patellar height indices in a cohort of HTO patients. METHODS: Patellar height (Caton-Deschamps, Blackburne-Peel and Insall-Salvati Indices and our newly developed Femoral Patellar Height Index) as well as tibial slope were analysed...

PURPOSE: There is no information comparing the results of fixed-bearing total knee replacement and mobile-bearing total knee replacement in the same patients previously treated by high tibial osteotomy. The purpose was therefore to compare fixed-bearing and mobile-bearing total knee replacements in patients treated with previous high tibial osteotomy. METHODS: We compared the results of 57 patients with osteoarthritis who had received a fixed-bearing prosthesis after high tibial osteotomy with the results of 41 matched patients who had received a rotating platform after high tibial osteotomy...

REVIEW
J Paul, A H Heitner, M Mauch, A B Imhoff
In the current literature, the rate of return to sports following high tibial osteotomy is high. Patients are largely able to carry out the type of exercise done before the onset of symptoms and are satisfied with the clinical outcome. In general, however, a differentiated view of the sporting ability should be made, and the different requirements of the sport should be considered. A classification according to functional and biomechanical movement analysis seems to advisable. In addition, the recommendations of the treating physician seem to have a high impact on the postoperative level of the sports activities of the patients...

BACKGROUND: When surgeons perform total knee arthroplasty in patients with knee osteoarthritis due to malunion following fractures around the knee joint, corrective osteotomy is recommended for severe deformities. Most such deformities are coronal plane varus or valgus deformities, and reports of sagittal plane flexion or extension deformities are rare. We describe a case in which a one-stage total knee arthroplasty was performed with extension corrective osteotomy in the sagittal plane...

BACKGROUND: The presented case illustrates the critical role of a detailed preoperative radiological evaluation in complex spine surgery. CASE REPORT: A 49-year-old patient was admitted for a revision surgery after L3-L5 fusion. Preoperative assessment showed preserved sagittal balance, coronal imbalance and valgus knee deformity. The patient reported pain of 8-10 in VAS (Visual Analogue Scale) and had an ODI (Oswestry Disability Index) of 60%. The first step of the surgery was L2-S1 fusion with decompression and spine deformity correction...

REVIEW
D Pape, A Hoffmann, R Seil
Physiologic alignment of the human lower leg is well defined. The etiology for malalignment comprises constitutional, degenerative and posttraumatic conditions. Osteotomies around the knee can correct the malalignment, provided that the origin of deviation is in proximity of the knee center. Crucial factors for the evaluation of axis deviation are the weight-bearing line, the mechanical axes of femur and tibia, the joint line angles and the center of the hip, knee and upper ankle joint. Careful preoperative planning is mandatory for reproducible clinical results...
