Arthrofibrosis is a complication that severely influences the clinical outcome after anterior cruciate ligament (ACL) reconstruction. This retrospective clinical study analyses risk factors and outcome after arthrolysis in a large population. Two hundred twenty-three patients who had undergone arthrolysis after ACL reconstruction were examined. Range of(More)
Background: Often anterior cruciate ligament (ACL) reconstruction is performed as outpatient surgery. This requires a patient friendly postoperative pain management. Three common procedures were compared in this trial. Methods: In a prospective, randomized study the effect of postoperative pain management using preoperative intraarticular anesthesia (0.1 mg(More)
While autologous chondrocyte implantation (ACI) has become an established surgical treatment for cartilage defects of the knee, only little is known about the clinical outcome following ACI for chondral or osteochondral lesion of the ankle. To evaluate efficiency and effectiveness of ACI for talar lesions was aim of the present meta-analysis. An OVID-based(More)
BACKGROUND The present study was designed to clarify which underlying indications can be currently considered the main reasons for failure after total knee arthroplasty as a function of time. METHODS We conducted a retrospective study that included all first revisions of total knee replacements during 2005 to 2010 at two high-volume arthroplasty centers.(More)
The clinical examination is a basic language of orthopaedics; it is how orthopaedic surgeons communicate with one another. However, each surgeon speaks a different dialect that has been influenced by where and with whom that surgeon trained, as well as that person's own experiences. Because of the inherent variability in the magnitude, direction, and rate(More)
BACKGROUND In a noticeable percentage of patients anterolateral rotational instabilities (ALRI) remain after an isolated ACL reconstruction. Those instabilities may occur due to an insufficiently directed damage of anterolateral structures that is often associated with ACL ruptures. Recent publications describe an anatomical structure, termed the(More)
Although no proven evidence exists for the use of drainage in primary total hip arthroplasty, such drainage is routinely used. This prospective, randomized study comprised 80 patients who underwent a non-cemented total hip arthroplasty using a minimally invasive anterolateral approach. Patients were divided into 2 groups of 40: group 1 underwent drainage(More)
To describe indication, approach and treatment modalities for the management of knee cartilage lesions among a selected European population. An electronic questionnaire covering general and specific items concerning cartilage repair at the knee joint was designed and disposed to survey cartilage treatment characteristics among a defined population of(More)
PURPOSE A test setup for clinical use in the awake and non-anesthetized patient measuring anteroposterior translation and rotation of the knee joint is the subject of validation. METHODS A measuring device featuring fixation of the foot at 30° of knee flexion with varus/valgus stress posts for the knee was developed. Tibial rotation (external/internal)(More)
AIM The aim of this study was the determination of the axial fixation load resting on smooth press-fit dowels needed for fixation of the patellar tendon graft (BTB) in order to reach the same fixation properties compared to the interference screw on anterior cruciate ligament (ACL) plasty. METHOD Bovine test specimens with 27 BTB grafts fixed in tibial(More)
