The efficacy of subcutaneous local analgesic infusion in the early postoperative period after bilateral total knee arthroplasty.

Objectives: This study aims to evaluate the analgesic and functional efficacy of subcutaneous local analgesic infusion (ScLAI) in the early postoperative period (especially on the second postoperative day) in patients undergoing simultaneous bilateral total knee arthroplasty with an intraoperative periarticular injection (PAI) of local analgesic cocktail.

Patients And Methods: Fifteen patients (1 male, 14 females; mean age 62 years; range 52 to 76 years) who underwent simultaneous bilateral total knee arthroplasty (30 knees) and who received the same pre- and intraoperative analgesic protocols were included in this randomized, double-blind, placebo-controlled study. By using a flexible catheter, bupivacaine was administered for ScLAI to either knee (ScLAI group) and placebo infusion was applied to the other one (control group).

Diagnostic efficacy of standard knee magnetic resonance imaging and radiography in evaluating integrity of anterior cruciate ligament before unicompartmental knee arthroplasty.

Objective: The purpose of this study was to investigate the diagnostic efficacy of standard magnetic resonance imaging (MRI) and plain radiographs in determining the status of anterior cruciate ligament (ACL) for surgical decision-making processes in cases of medial unicompartmental knee arthroplasty (UKA).

Methods: A total of 59 knees of 36 consecutive patients who underwent knee replacement surgery were analyzed retrospectively. MRI scans were assessed independently by 3 observers (radiologists), while the plain radiographs were evaluated by an independent radiologist.

Biomechanical evaluation of syndesmotic screw design via finite element analysis and Taguchi's method.

Background: Screw fixation of syndesmotic injuries facilitates ligament healing and restoration of ankle stability, but failure of the screw might threaten the success of the treatment. Screw design parameters, such as outer diameter, inner diameter, thread pitch, leading edge radius, trailing edge radius, leading edge angle, and trailing edge angle, might have effects on the stresses that occur in the screws. This is the first study, to our knowledge, to investigate which geometric screw parameters play key roles in stresses that occur in screws used for syndesmotic fixation.

Suture anchor fixation strength with or without augmentation in osteopenic and severely osteoporotic bones in rotator cuff repair: a biomechanical study on polyurethane foam model.

Background: The purpose of the present study was to compare the results of various types of anchor applications with or without augmentation in both osteopenic and severely osteoporotic bone models.

Methods: Two different types of suture anchors were tested in severely osteoporotic (SOP) and osteopenic polyurethane (PU) foam blocks using an established protocol. An Instron machine applied static loading parallel to the axis of insertion until failure, and the mean anchor failure strengths were calculated.

An assessment of sleep quality in patients undergoing total knee arthroplasty before and after surgery.

Methods: The study included 42 patients (32 females, 10 males) who underwent total knee arthroplasty for primary knee osteoarthritis. For each patient the preoperative 1 day and postoperative 3 months results of Pittsburgh Sleep Quality Index (PSQI) and 100-mm visual analogue scale (VAS) were compared.

Femoral neck stress fracture in children: a case report, up-to-date review, and diagnostic algorithm.

Stress fracture of the femoral neck in skeletally immature individuals is a rare condition and generally seen as compressive type. Because the condition may lead to disastrous complications, femoral neck stress fracture must also be kept in mind in the differential diagnosis of pediatric hip pain. We present a case of compressive-type stress fracture of the femoral neck in a 10-year-old girl with left hip pain that was sustained for 4 weeks and emphasize the difficulty of early diagnosis with only a radiographic evaluation and put forward an algorithm for diagnosis and treatment.

Methods: A three-dimensional finite element model of an ankle was constructed from serial axial sections from an existing two-dimensional computed tomographic image. Constructions of syndesmosis fixation with 3.

Convex short segment instrumentation and hemi-chevron osteotomies for Putti type 1 thoracic hemivertebrae: a simple treatment option for patients under 5 years old.

The comparison of the effects of intraoperative bleeding control and postoperative drain clamping methods on the postoperative blood loss and the need for transfusion following total knee arthroplasty.

Objective: We aimed to determine and compare the effects of intraoperative bleeding control and two hours postoperative drain clamping method on postoperative wound drainage and the need for donor blood transfusion following total knee arthroplasty (TKA).

Methods: Seventy-one patients who underwent TKA were randomly assigned into two groups. Fourty-four knees of 32 patients comprised Group A and 51 knees of 39 patients comprised Group B.

Bilateral post-injection fibrosis of the gluteal region mimicking lumbar disc herniation: a case report.

Tissue fibrosis is a known complication of intramuscular injections, which is especially seen in children due to vaccinations and injections. Herein we report a case of post injection gluteal fibrosis that had undergone two unsuccessful lumbar discectomies to treat the symptoms of this disease.A 45 years old male patient was consulted to our clinic from the department of neurochirurgy with complaints of bilateral hip pain.

Easy retrieval of polyaxial tulip-head pedicle screws by "U" rod technique.

The number of fusion surgeries increase each year which also increase the need for implant removal. In some cases, it can be extremely hard to remove a pedicle screw especially when there is a mismatch of the screw and the screwdriver. Also the screwdrivers can be contaminated during the operation, and this will cause a delay till the instruments are re-sterilized.

Treatment with unsaponifiable extracts of avocado and soybean increases TGF-beta1 and TGF-beta2 levels in canine joint fluid.

Avocado and soya unsaponifiables (ASU) are plant extracts used as a slow-acting antiarthritic agent. ASU stimulate the synthesis of matrix components by chondrocytes, probably by increasing the production of transforming growth factor-beta (TGF-beta). TGF-beta is expressed by chondrocytes and osteoblasts and is present in cartilage matrix.
