PURPOSE: The correlation between tibial tuberosity-trochlear groove distance (TT-TG) and joint size, taking into account several different parameters of knee joint size as well as lower limb dimensions, is evaluated in order to assess whether TT-TG indices should be used in instead of absolute TT-TG values. METHODS: This study comprised a retrospective analysis of knee CT scans, including 36 cases with patellofemoral instability (PFI) and 30 controls. Besides TT-TG, five measures of knee joint size were evaluated in axial CT slices: medio-lateral femur width, antero-posterior lateral condylar height, medio-lateral width of the tibia, width of the patella and the proximal-distal joint size (TT-TE)...

BACKGROUND: Evaluation of distal extensor mechanism alignment continues to evolve in children with patella instability. Prior studies support the use of the tibial tubercle to trochlear groove (TT-TG) distance but limitations exist for this measurement including: changes in the TT-TG distance with knee flexion, difficulty with finding the deepest part of a dysplastic trochlea, and limitations regarding identification of the site of the anatomic abnormality. The tibial tubercle-posterior cruciate ligament (TT-PCL) distance has been introduced as an alternative measure to address the shortcomings in the TT-TG distance by quantifying the position of the TT independent of the trochlea and with respect to the tibia only...

Fractures of the proximal epiphysis of the tibia are rare, representing 0.5 to 3.0% of all epiphyseal injuries. These injuries can damage the popliteal vessels and their bifurcation, affecting the blood supply of the lower limb, as well as the nerves below the knee. Epiphyseal growth arrest is also a potential complication, leading to various angular deformities. We present a case of a 13-year-old male athlete with a posteriorly displaced Salter-Harris type II fracture of the proximal epiphysis of the left tibia who was treated conservatively with closed reduction and cast immobilization...

Akio Sakamoto, Shuichi Matsuda
INTRODUCTION: Osteochondroma is a common benign bone tumor, protruding from the underlying normal bone. Osteochondromas can cause pain depending on their location and size. The pes anserinus is located at the proximal medial side of the tibia, where the tendinous insertions of the sartorius, gracilis and semitendinosus muscles collectively attach. Pes anserinus syndrome, or anserine bursitis, is a painful condition of the pes anserinus, and is more common in adults typically with overweight females...

INTRODUCTION: Trophic disorders of the extremities are a common complication of systemic sclerosis (SSc), mainly related to microvascular damage. However, SSc seems to be a risk factor for premature athero-thrombotic disease that can affect the peripheral arteries, participate in the occurrence of trophic disorders and promote the occurrence of infectious complications. The objective of this study was to assess the prevalence of arterial disease of the limbs in SSc patients. METHODS: Consecutive inclusions in the context of a multidisciplinary consultation centered on disability of the hand with collection of clinical data [cardiovascular risk factors (CVRF), history of trophic disorders of ischemic origin, peripheral pulse palpation, Allen maneuver the upper (UL) and lower limbs (LL)], and hemodynamic data (flow recorded by Doppler in radial, ulnar, anterior and posterior tibial arteries, and measurement of systolic indices ankles)...

REVIEW
M J Feucht, T Tischer
BACKGROUND: The osseous geometry of the lower limb has a significant impact on knee instability after ligament injuries, and osseous malalignment has been shown to be a significant risk factor for the failure of ligament reconstruction procedures. Therefore, osteotomies around the knee have gained importance as a combined or isolated treatment option in the ligament deficient and malaligned knee. In addition to unloading of an arthritic knee compartment, osteotomies are also performed to protect a reconstructed ligament and to stabilize the joint without ligament surgery...

Primary anterior cruciate ligament (ACL) reconstruction is a common orthopaedic procedure. A graft failure rate of 5% to 10% after primary ACL reconstruction has resulted in an increased need for revision ACL reconstruction. ACL reconstruction failure etiologies include trauma, technical errors, and biologic factors. Based on the current literature, the outcomes of revision ACL reconstruction are clearly inferior compared with those of primary reconstruction. A thorough patient evaluation, including surgical history, a physical examination, and imaging studies, is crucial in the assessment of a failed ACL reconstruction...

In severe ocular surface disease with limbal stem cell deficiency associated with severe dry eye, penetrating keratoplasty is likely to fail. In these cases, and provided the posterior segment is normal, keratoprosthesis surgery (KPro) can achieve visual rehabilitation. In KPros with an autologous biological haptic, a bone-tooth-complex (osteo-odonto-keratoprothesis, OOKPro) or a piece of tibial cortex (tibia-keratoprosthesis, TKPro) is used to carry a PMMA cylinder. This construct can successfully be implanted even in severely dry eyes and in those with autoimmune disease, in which other KPro designs frequently fail...
