INTRODUCTION 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. MATERIAL AND METHODS Two hundred twenty-three patients who had undergone arthrolysis after ACL(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)
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)
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)
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)
OBJECTIVE Restoration of free knee motion taking into account knee extension, knee flexion, and patella mobility. INDICATIONS Prolonged knee motion restriction after anterior cruciate ligament (ACL) reconstruction, persistent decreased patella mobility, or extension deficit. CONTRAINDICATIONS Existing significant joint irritation or active reflex(More)
Reconstruction of the cruciate ligaments is elective surgery performed mainly on younger people. Therefore, complications are especially tragic. Diagnostics and indications include the possibility of complications. The complexity of an injury must be thoroughly appreciated, and to avoid intraoperative complications, it is important for the surgeon to have a(More)
PURPOSE 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. (More)
OBJECTIVE Surgical technique in total knee arthroplasty (TKA) to combine the femur first and tibia first techniques in order to reduce surgical mistakes regarding rotation and alignment. INDICATIONS Symptomatic arthritis of the knee. CONTRAINDICATIONS General contraindications for TKA. SURGICAL TECHNIQUE Osseous preparation starting with a distal(More)
In a retrospective study with a population over 65 years, sports activity was conducted 6 years after cruciate retaining (CR) total condylar knee arthroplasty (TKA) with rotating platform (RP). Eighty-one Patients (71.8±5.4years) were examined at follow-up 6.4±0.9 years postoperative. Sport was practiced 5.3 hours every week in mean. Patients were active in(More)
