The role of arthroscopy in patients with persistent hip pain after total hip arthroplasty.

Background: Total hip arthroplasty (THA) is a safe and successful procedure for the treatment of osteoarthritis. One of the most common postoperative problems remains persistent hip pain. The arthroscopic evaluation of persistent hip pain following THA can be a valuable diagnostic tool in a select number of patients when carried out by experts in this technique.

Refractory adhesive capsulitis under acitretin therapy.

Background: Adhesive capsulitis (AC) is characterized by a limited active and passive motion. Although the exact pathology remains unknown, a number of contributing factors are discussed.

Objective: AC has probably been caused by the Re-PUVA therapy (PUVA irradiation plus acitretin) of a cutaneous T-cell lymphoma, type mycosis fungoides.

Primary stability of cementless threaded acetabular cups at first implantation and in the case of revision regarding micromotions as indicators.

The primary stability of cementless total hip endoprosthesis is of vital importance for proximate, long-term osteointegration. The extent of micromotions between implant and acetabulum is an indicator of primary stability. Based on this hypothesis, different cementless hip joint endoprosthesis were studied with regard to their micromotions.

Late Periprosthetic Joint Infection due to Staphylococcus lugdunensis Identified by Matrix-Assisted Laser Desorption/Ionisation Time of Flight Mass Spectrometry: A Case Report and Review of the Literature.

Staphylococcus lugdunensis, member to the group of coagulase-negative staphylococci, is previously thought to be rarely isolated. Recently other staphylococci have been described, which were supposedly related to S. lugdunensis, such as Staphylococcus pseudolugdunensis and Staphylococcus pettenkoferi.

How reliable is MRI in diagnosing cartilaginous lesions in patients with first and recurrent lateral patellar dislocations?

Background: Lateral dislocation of the patella (LPD) leads to cartilaginous injuries, which have been reported to be associated with retropatellar complaints and the development of patellofemoral osteoarthritis. Therefore, the purpose of this study was to determine the reliability of MRI for cartilage diagnostics after a first and recurrent LPD.

Methods: After an average of 4.

Anatomical and surgical study of volume determination of the anterolateral epidural space nerve root L5/S1 under the aspect of epidural perineural injection in minimal invasive treatment of lumbar nerve root compression.

Herniated intervertebral disc causes in a great number of cases of lumbar nerve root compression, especially in the segment L5/S1. Other reasons responsible for stress to the lumbar spinal root are the spinal canal stenosis and the postdiscotomy syndrome. For patients without neurological deficiencies, the conservative treatment includes different epidural injection techniques.

Hoffa's fat pad impingement treated arthroscopically: related findings on preoperative MRI in a case series of 62 patients.

Introduction: The morphology of painful impingement of the infrapatellar fat pad (Hoffa's disease), which is characterized by inflammation, swelling, hypertrophy, fibrosis, and/or calcifications, has been well described. The purpose of this study was to investigate whether corresponding characteristic MRI findings could be assessed in patients with infrapatellar fat pad impingement.

Materials And Methods: This study includes 62 patients with secondary symptomatic Hoffa's fat pad impingement.

Arthroscopy vs. MRI for a detailed assessment of cartilage disease in osteoarthritis: diagnostic value of MRI in clinical practice.

Background: In patients with osteoarthritis, a detailed assessment of degenerative cartilage disease is important to recommend adequate treatment. Using a representative sample of patients, this study investigated whether MRI is reliable for a detailed cartilage assessment in patients with osteoarthritis of the knee.

Methods: In a cross sectional-study as a part of a retrospective case-control study, 36 patients (mean age 53.

Early patellofemoral osteoarthritis caused by an osteochondral defect after retrograde solid nailing of the femur in sheep.

Background: Retrograde femoral nailing (RFN) is an increasingly used technique for internal fixation of femoral fractures. Geometrically and empirically, the nail entry zone is close to the center of the femoral groove, causing concern about the development of patellofemoral osteoarthritis.

Methods: We studied the effect of opening the distal femur through the femoral groove on the development of osteoarthritis in sheep after retrograde reamed insertion of a solid titanium nail into the femoral canal.

Reconstruction of the greater trochanter with an allograft after resection of a giant cell tumor.

Our report involves the rare case of a giant cell tumor which filled out the greater trochanter. After complete resection of the greater trochanter, reconstructive surgery using a bone allograft was performed. Although the allograft healed without any complications, it was resorbed within 28 months, and there were no signs of infection or tumor recurrence during this period.
