A novel robot-assisted knee arthroplasty system (ROSA) and 1-year outcome: A single center experience.

Background: Total knee arthroplasty is a successful procedure in the treatment of knee osteoarthritis. Searches in surgical technique have focused surgeons in particular on implant alignment. For this purpose, the use of robot-assisted total knee arthroplasty has become increasingly common in the last 10 years.

Avulsion Fracture and Myositis Ossificans in a Professional Teenage Dancer: A Case Report.

Fractures of the transverse processes in the lumbar vertebrae occur as the result of major forces such as direct blunt trauma, violent lateral flexion-extension forces, avulsion of the psoas muscle, or Malgaigne fractures of the pelvis. Dancers make repeated and forceful hyperextension and flexions of the spine, which may cause fractures of the transverse processes of the lumbar vertebrae. Repeated trauma of muscles in dancers may cause avulsion fractures and myositis ossificans.

Effect of surgical closing in total knee arthroplasty at flexion or extension: a prospective, randomized study.

Purpose: The aim of this study was to evaluate the effect of knee position during wound closure (flexed vs. extended) in total knee arthroplasty on knee strength and function, as determined by knee society scores and isokinetic testing of extensor and flexor muscle groups.

Methods: In a prospective, randomized, double-blind trial, 29 patients were divided in two groups: for Group 1 patients, surgical closing was performed with the knee extended, and for Group 2 patients, the knee flexed at 90°.

The comparison of the effect of corticosteroids and platelet-rich plasma (PRP) for the treatment of plantar fasciitis.

Introduction: In this study, the results of local injection of platelet-rich plasma (PRP) and corticosteroids in the treatment of plantar fasciitis were compared.

Patients And Methods: Sixty patients who were diagnosed as plantar fasciitis and treated conservatively for at least 3 months and had no response to conservative treatment modalities were involved in this study. The first 30 consecutive patients were treated by local injection of 2 mL of 40 mg Methylprednisolone with 2 mL of 2% prilocaine (metilprednizalone) and the second 30 patients were treated by injecting 3 mL PRP after 2 mL of 2% prilocaine injection.

Role of pathophysiology of patellofemoral instability in the treatment of spontaneous medial patellofemoral subluxation: a case report.

Introduction: Medial patellar subluxation is usually seen after lateral retinacular release. Spontaneous medial subluxation of the patella is a very rare condition. There are few reports in the literature on the pathophysiology of iatrogenic medial patellar subluxation.

Axial plane coverage and torsion measurements in primary osteoarthritis of the hip with good frontal plane coverage and spherical femoral head.

Introduction: Mechanical factors play a role in pathogenesis of primary osteoarthritis of the hip. Torsion measures were made to detect whether there is a causal relationship between increase or decrease of femoral anteversion, acetabular anteversion, and osteoarthritis. There are no studies in the literature indicating a relationship between axial plane coverage and osteoarthritis of the hip.

Single or double distal locking in intramedullary nailing of tibial shaft fractures: a prospective randomized study.

Background: The number of distal locking screws may have an effect on union, complication rates and operation time.

Does Salter innominate osteotomy with transiliac lengthening effect triradiate cartilage or cause posterior coverage insufficiency?

Introduction: To treat neglected developmental dysplasia of the hip (DDH), we performed Salter innominate osteotomy with a modification of transiliac lengthening. We asked whether this modified technique caused posterior coverage problems and triradiate cartilage injury.

Methods: We retrospectively reviewed 45 patients with unilateral DDH treated by open reduction and femoral shortening and modified Salter innominate osteotomy.

Immediate incorporated hip spica casting in pediatric femoral fractures: comparison of efficacy between normal and high-risk groups.

Background: Immediate hip spica casting is the most commonly used method for the treatment of pediatric femoral fractures. The main disadvantage of the method is the unacceptable shortening (>25 mm), which may occur during the treatment. Buehler et al described the so-called telescope test to identify the cases with a relatively high risk of unacceptable shortening.

[The effectiveness of short-segment posterior instrumentation of thoracolumbar burst fractures].

Objectives: We evaluated the results of short-segment posterior instrumentation of thoracolumbar burst fractures and investigated correlations between radiographic and functional results as well as factors that affected correction losses.

Methods: We reviewed 48 patients (30 males, 18 females; mean age 40+/-14 years; range 18 to 67 years) who underwent short-segment posterior instrumentation with pedicle screws and fusion. The most common involvement was at L1 in 18 patients (37.

[The results of intramedullary nailing in children who developed redisplacement during cast treatment of both-bone forearm fractures].

Objectives: We assessed the results of intramedullary nailing in children who developed redisplacement during cast treatment of both-bone forearm fractures.

Methods: Twenty-eight children (19 boys, 9 girls; mean age 10.6 years; range 8 to 15 years) were treated with intramedullary fixation upon failure of initial reduction of both-bone forearm fractures after a mean of four weeks (range 3 to 6 weeks) of cast treatment.

Residual axial plane deformities after hip reconstruction for developmental dysplasia of the hip after walking age.

Children with developmental dysplasia of the hip after walking age can be treated with one-stage combined operations. In these procedures, complex deformity corrections at both frontal and axial planes are performed in the guidance of intraoperative stability tests. The reports about the results of these procedures focus on frontal plane assessments but neglect to assess axial plane corrections.

Bilateral patellar tendon rupture in a child: a case report.

Patellar tendon rupture in children is very rare. When it occurs, patellar tendon is usually ruptured either from the upper end as a sleeve fracture of the patella or from lower end as an avulsion fracture of the tibial tuberosity. In this report, we present the case of an otherwise healthy 9-years-old boy who had subsequent bilateral patellar tendon ruptures through the midparts, which has not been published previously in the literature.

Simultaneous rupture of the quadriceps tendon and contralateral patellar tendon in a patient with chronic renal failure.

Simultaneous quadriceps and patellar tendon rupture is rare. Mechanical factors and coexisting systemic and local factors are taken into consideration in the pathogenesis of these ruptures. In patients with some chronic systemic diseases, simultaneous rupture can occur spontaneously or with minor traumas.
