Calcaneal lengthening for planovalgus deformity in children with cerebral palsy.

Background: In children with cerebral palsy, planovalgus deformity of the foot is common. The aim of this study was to evaluate the outcome of calcaneal lengthening for the treatment of planovalgus foot deformity in children with cerebral palsy.

Materials And Methods: We reviewed 19 children (28 feet) treated between 1996 and 2004 in our institution.

[Implementation of standardized postoperative pain therapy for orthopaedic patients. Comparison between unsystematic and standardized pain therapy].

Background: The painless clinic and postoperative pain therapy are currently major issues in the management of surgical procedures. The aim of this study was to evaluate the benefit of a standardized pain therapy on the postoperative pain level after orthopaedic procedures.

Patients And Methods: We investigated two different groups of patients who underwent an orthopaedic surgical procedure.

Patient activity after total hip arthroplasty declines with advancing age.

Evaluation of patient activity is essential for clinical decision making before THA. To correlate age progression to patient activity after THA, we determined the number of walking cycles of 105 patients in different age groups by decades. Patients on average performed 6144 walking cycles per day (2.

The Daily Activity Questionnaire: a novel questionnaire to assess patient activity after total hip arthroplasty.

Expensive electronic accelerometers are the only validated method to determine patient activity levels. The aim of this study was to develop a clinical questionnaire to assess patient activity. The Daily Activity Questionnaire (DAQ) was developed and evaluated using 3 groups of patients with osteoarthritis of the hip.

No migration of acetabular cups after prophylaxis for heterotopic ossification.

The possibility of migration of cementless cups in total joints after prophylaxis of heterotopic ossification with irradiation or nonsteroidal antiinflammatory drugs is a concern. Data investigating component stability with digital methods are lacking. This prospective study analyzed the migration of cementless cups after indomethacin and irradiation prophylaxis with the digital Einzel-Bild-Röntgen-Analyse tool.

No increased stem subsidence after arthroplasty in young patients with femoral head osteonecrosis: 41 patients followed for 1-9 years.

Background: Poor bone stock in patients with osteonecrosis of the femoral head may be a reason for poor outcome after hip replacement. One way of studying bone quality is to measure implant migration. We thus investigated the clinical and radiographic results of cementless THR in younger patients with femoral head osteonecrosis.

[A novel questionnaire to assess activity in patients after hip arthroplasties].

Background: Until now, the activity of the lower limb could only be exactly measured with expensive electronic pedometers. The aim of this study was to develop a feasible questionnaire to measure the activity of patients after arthroplasty.

Methods: The "Daily Activity Questionnaire" (DAQ) was developed in several steps and the evaluation was carried out in three groups of patients with osteoarthritis of the hip (160 patients and 855 investigated days).

Reliability, validity and responsiveness of the German Short Musculoskeletal Function Assessment Questionnaire in patients undergoing surgical or conservative inpatient treatment.

Objective: The patient-based evaluation of outcome is gaining increased importance. The aim of the study was to demonstrate the reliability, validity and responsiveness of the German version of the Short Musculoskeletal Function Assessment Questionnaire (SMFA-D) in patients undergoing surgical or conservative treatment.

Methods: Three hundred and thirty-two patients suffering from osteoarthritis of the hip or knee, rheumatoid arthritis or rotator cuff tear undergoing surgical or medical inpatient treatment were followed up for 12 month.

[Comparative analysis of patient-centered outcome of total hip and knee arthroplasty].

Aim: The aim of the present study was a comparative investigation of the functional improvement reported by patients suffering from primary osteoarthritis of the knee or hip undergoing total joint replacement and assessed at 3 months.

Method: In a prospective, controlled clinical trial, 56 patients with primary osteoarthritis of the hip and 59 patients with primary osteoarthritis of the knee undergoing total joint replacement were assessed at two measuring times (day of admission = t1 and 3-month follow-up = t2) using the XSMFA-D (Extra Short Musculoskeletal Function Assessment Questionnaire--German version), WOMAC (Western Ontario and McMasters Universities) arthrosis index and FFb-H OA (Function Assessment Questionnaire Hannover Osteoarthritis). The statistical analysis included effect sizes as standardised response mean, t-test and covariance analysis.

[Evaluation of the Extra Short Musculoskeletal Function Assessment questionnaire XSMFA-D in patients with musculoskeletal disorders and surgical or medical in-patient treatment].

Aim: The present study had the objective of evaluating the psychometric characteristics of the shortened 16-item version of the German Short Musculoskeletal Function Assessment questionnaire (XSMFA-D), which was designed for routine assessment of functional capacity in patients with various orthopaedic disorders treated either surgically or medically.

Methods: A total of 382 patients from seven different samples with either osteoarthritis of the knee, osteoarthritis of the hip, rheumatoid arthritis or rotator cuff tear treated either in surgical hospitals or rehabilitation settings were assessed both before and after treatment. The XSMFA-D was compared with both questionnaires measuring similar constructs and widely accepted indicators of health status in musculoskeletal disorders.

[Evaluation of a simple test for shoulder function in patients with surgically treated rotator cuff injuries].

Introduction: To assess overall shoulder function a simple examination of the range of motion and strength may not be sufficiently representative. because the shoulder in its daily use is often required for repetitive activities, fatigue at an early stage could be a sign of disturbed shoulder function. Therefore the shoulder function test (SFT) was created to incorporate the factor time into shoulder assessment.

Knee arthroplasty for spontaneous osteonecrosis of the knee: unicompartimental vs bicompartimental knee arthroplasty.

Spontaneous osteonecrosis of the knee (SON) is an osteonecrosis that mainly affects the medial femoral condyle. In endstage SON, knee arthroplasty is the therapy of choice. Because of the unicompartimental nature of the knee, unicondylar knee arthroplasty is considered an ideal implant for treatment of this condition.

[Evaluating the reliability, validity and responsiveness of the german short musculoskeletal function assessment questionnaire, SMFA-D, in inpatient rehabilitation of patients with conservative treatment for hip osteoarthritis].

Background: Modern patient based outcome measures like the SMFA-D (German Short Musculoskeletal Function Assessment Questionnaire) are able to detect the impairment and functional capacity of patients with musculoskeletal extremity disorders. The SMFA-D was successfully evaluated in several cohorts treated operatively for osteoarthritis of the knee and hip, rotator cuff tears and rheumatoid arthritis. The aim of the present study was the evaluation of the SMFA-D in patients with conservative treatment for hip osteoarthritis.

[Development of a questionnaire based on the Constant-Murley-Score for self-evaluation of shoulder function by patients].

The aim was to develop a German questionnaire for self-assessment of shoulder function equivalent to the Constant-Score (CS). To evaluate the retest reliability, the CS questionnaire was completed twice within 1 week by 47 patients prior to shoulder surgery. For validation the CS was assessed by the physician after the second self-test.

The German Short Musculoskeletal Function Assessment questionnaire: reliability, validity, responsiveness, and comparison with the Short Form 36 and Constant score--a prospective evaluation of patients undergoing repair for rotator cuff tear.

In a prospective clinical trial, first the German Short Musculoskeletal Function Assessment questionnaire (SMFA-D) was tested for reliability, validity, and responsiveness in 23 patients with rotator cuff tears, and secondly the Short Form (SF)-36, and the Constant score were evaluated comparatively in 45 patients with rotator cuff tear undergoing open repair. Retest reliability was excellent for the functional index of the SMFA-D and satisfactory for the bother index. The SMFA-D showed good validity and responsiveness.

[Design and evaluation of the Extra Short Musculoskeletal Function Assessment Questionnaire XSMFA-D].

Aim: The XSMFA-D (German Extra Short Musculoskeletal Function Assessment Questionnaire) was developed on the basis of the SMFA-D to provide a short questionnaire for assessment of the functional status from patient's perspective in routine use.

Methods: Based on psychometric and medical aspects 16 items were extracted from the SMFA-D during an iterative process. 633 SMFA-D questionnaires of 199 patients were used as basic data.
