Coronal Knee Alignment and Tibial Rotation in Total Knee Arthroplasty: A Prospective Cohort Study of Patients with End-Stage Osteoarthritis.

Several studies have found a relationship between the rotational anatomy of the distal femur and the overall coronal lower limb alignment in knees with osteoarthritis (OA). Less is known about the rotation of the proximal tibia, especially in the context of total knee arthroplasty (TKA), where one of the goals of the surgery is to achieve the appropriate component-to-component rotation. The aim of this study was to investigate the relationship between the coronal alignment of the lower extremity and the relative proximal tibial rotation.

Mobile wireless monitoring system for prehospital emergency care.

Background: Latest achievement technologies allow engineers to develop medical systems that medical doctors in the health care system could not imagine years ago. The development of signal theory, intelligent systems, biophysics and extensive collaboration between science and technology researchers and medical professionals, open up the potential for preventive, real-time monitoring of patients. With the recent developments of new methods in medicine, it is also possible to predict the trends of the disease development as well the systemic support in diagnose setting.

Results of total hip arthroplasty using a bionic hip stem.

Purpose: The trabecular-orientated bionic hip stem was designed to mimic the natural force transmission through the femur in total hip arthroplasty, resulting in supposedly longer prosthesis survivability. The aim of this study was to compare the second-generation bionic hip stem to a standard uncemented hip stem.

Methods: A group of 18 patients (21 hips) who underwent total hip arthroplasty with a bionic stem (bionic group) was compared with a historic group of 12 patients (12 hips) treated with standard anatomic hip stem (control group).

Long term results of operative treatment of knee osteochondritis dissecans.

Purpose: This retrospective study was designed to evaluate the hypothesis that open reduction internal fixation (ORIF) of an unstable osteochondritis dissecans (OCD) lesion results in a high percentage of acceptable outcomes at long-term follow-up.

Methods: Eight patients who had been treated with ORIF for unstable knee OCD lesions were identified. Long-term outcomes were assessed with a Subjective Knee Evaluation Form and Knee Examination Form of the International Knee Documentation Committee (IKDC 2000) and an OCD specific Hughston rating scale.

Dynamic versus rigid stabilization for the treatment of disc degeneration in the lumbar spine.

Study Design:  Retrospective cohort study.

Clinical Question:  This study aimed to describe the outcome of stabilization surgery with dynamic instrumentation for degenerative disc disease. The results were compared with age- and gender-matched peers treated with traditional fusion with rigid instrumentation.

Quality of life and clinical outcome comparison of semitendinosus and gracilis tendon versus patellar tendon autografts for anterior cruciate ligament reconstruction: an 11-year follow-up of a randomized controlled trial.

Background: There are still controversies about graft selection for primary anterior cruciate ligament reconstruction. Prospective, randomized long-term studies are needed to determine the differences between the graft materials.

Hypothesis: Eleven years after anterior cruciate ligament reconstruction there is no difference in functional outcome and quality of life between patients with patellar tendon or hamstring tendon autografts; however, the patients with patellar tendon autograft would have a higher prevalence of osteoarthritis.

Comparison of drainage techniques on prolonged serous drainage after total hip arthroplasty.

The aims of this study were to determine (1) whether the duration of closed suction drainage affects the occurrence and duration of prolonged serous drainage and (2) if closed suction drains could be omitted according to the wound and/or thigh appearance after unilateral primary total hip arthroplasty. One hundred thirty-nine patients undergoing total hip arthroplasty were randomized into 3 groups: 42 patients received no drainage, 46 patients received drainage for 24 hours, and 51 patients received drainage for 48 hours. No differences with respect to occurrence and duration of prolonged serous drainage were found between the 2 groups with drains.

The effect of graft choice on functional outcome in anterior cruciate ligament reconstruction.

A prospective, randomised, 5-year follow-up study was designed to compare the functional results between patellar tendon and hamstring tendon autografts after anterior cruciate ligament reconstruction. Primary reconstruction was performed in 32 patients using the central third of the patellar ligament and in 32 patients using double-looped semitendinosus and gracilis tendons. All reconstructions were performed by a single surgeon, with identical surgical technique and rehabilitation protocol.

Long-term results after open Bankart operation for anterior shoulder instability. A 3- to 16-year follow-up.

The open Bankart procedure is still considered the gold standard for patients with recurrent posttraumatic anterior shoulder instability. The purpose of this retrospective study was to analyze long-term results after open Bankart procedure in 83 patients that were operated between 1987 and 2000 and to evaluate the rate of recurrent instability, level of function and range of motion. The mean follow-up time was 9 (3-16) years.
