Despite the fact that common surgical techniques for the treatment of genu varum usually correct the malalignment in the affected knee, these methods have significant complications and cause problems in the long term. Retro-tubercle opening-wedge high tibial osteotomy is among the newer techniques for the treatment of genu varum. The goal of this study was to compare the results of retro-tuberc...

BACKGROUND Knee cartilage defects may play an important role in early osteoarthritis, but little is known about their natural history. METHODS Knee cartilage defect score (range, 0-4), cartilage volume, and bone surface area were determined using T1-weighted fat-saturated magnetic resonance imaging in 325 subjects (mean age, 45 years) at baseline and 2 years later. RESULTS Thirty-three perc...

The aim of this study was to determine if microfractures improve the outcome of high tibial osteotomy in patients with medial compartmental osteoarthritis in genu varum. Forty patients presenting with Outerbridge grade III and IV chondropathies on the femoral and/or the tibial joint surface underwent high tibial osteotomy with Puddu plates (Arthrex, Inc, Naples, Florida) for primary medial comp...

Large meniscal defects are a common problem for which treatment options are limited. Successful meniscal regeneration has been achieved by using grafts of small intestinal submucosa in posterior, vascular meniscal defects in a dog model. This study investigates the long-term effects of a tibial tunnel fixation technique and a clinically based meniscectomy defect on meniscal regeneration using t...

Purpose To evaluate the radiologic and functional outcomes of medial open wedge high tibial osteotomy (HTO) combined with arthroscopic procedure in patients with medial osteoarthritis. Materials and Methods From June 1996 to March 2010, 26 patients (32 knees) who underwent medial open wedge osteotomy and arthroscopic operation for medial osteoarthritis were retrospectively reviewed. Measureme...

Bone stock deficiency in primary as well as in revision total knee arthroplasty (TKA) represents a difficult problem to surgeon with regard to maintaining proper alignment of the implant components and in establishing a stable bone-implant interface. Different surgical procedures are available in these situations, for instances the use of bone cement, prosthetic augments, custom implant, and wi...

BACKGROUND Although a change in tibial slope may occur during a medial opening wedge osteotomy, calculations have not been defined to address this problem. The authors investigated geometric factors important to correct axial alignment and tibial slope during osteotomy. PURPOSE To calculate, through 3-dimensional analysis of the proximal tibia, how the angle of the opening wedge along the ant...

Background Fractures of the tibial eminence, first described by Poncet in 1875, are bony avulsions of the ACL from its insertion on the intercondylar eminence of the tibia (Figure 1). Tibial eminence fractures are relatively rare with an incidence of approximately 3 per 100,000 per year, and account for 2 to 5% of knee injuries in the pediatric pediatric population. While most commonly seen in ...

  A new technique in spring ligament reconstruction using medial half of posterior tibial tendon is demonstrated as a means of supporting the arch. In addition a new concept of double bundle PTT reconstruction based on anatomical attachments of original PTT is presented with the goal of obtaining the full function of PTT.

of the Caucasian population. The purpose of this study was to investigate the morphometry of the proximal tibia in thestandard resected surface of total knee arthroplasty (TKA).Methods: In this descriptive study, the anthropometric data of the proximal tibia were measured in 132 knees (80 malesand 52 females) using magnetic resonance imaging in 2015. The collected data include...
