Better functional results of opening wedge HTO for varus knees with medial osteoarthritis than opening wedge LFO for valgus knees with lateral osteoarthritis.

Aims: To compare time dependent functional improvement for patients with medial, respectively lateral knee osteoarthritis (OA) after treatment with opening wedge osteotomy relieving the pressure on the osteoarthritic part of the knee.

Methods: In all, 49 patients (52 knees) with a mean age of 47 years (31 to 64) underwent high tibial osteotomies (HTO), and 24 patients with a mean age of 48 years (31 to 62) low femoral osteotomies (LFO) with opening wedge technique due to medial, respectively lateral knee OA with malalignment. All osteotomies were stabilized with a Puddu plate and bone grafting performed in the same time period (2000 to 2008).

Editorial Commentary: High Tibial Osteotomy for Varus Knees With Medial Osteoarthritis May Prevent Total Knee Arthroplasty.

High tibial osteotomy for unilateral medial knee osteoarthritis unloads the osteoarthritic area, gives pain relief, and may prevent later osteoarthritis if performed for the ideal indications. The risk of conversion of high tibial osteotomy to total knee arthroplasty is higher if osteoarthritis has advanced too far and for overweight persons, cigarette smokers, older patients, female patients, patients with a high level of comorbidity, and patients with under-correction of the varus malalignment.

Similar risk of ACL graft revision for alpine skiers, football and handball players: the graft revision rate is influenced by age and graft choice.

Objectives: The risk of graft revision following ACL reconstruction may depend on the sport type the individuals are engaged in. The purpose of this study was to report the ACL graft revision rate in alpine skiers, football and handball players.

Materials And Methods: Primary ACL reconstructions and graft revision data from 2004 to December 2016 were obtained from the Norwegian Cruciate Ligament Registry.

Good functional results following high tibial opening-wedge osteotomy of knees with medial osteoarthritis: A prospective study with a mean of 8.3years of follow-up.

Background: To report time dependent functional improvement and predictive risk factors for failure when the load in varus knees with medial osteoarthritis is shifted from the medial to the lateral knee compartment.

Methods: Forty-nine consecutive patients (52 knees), mean age 47 (31-64) years, underwent a high tibial opening-wedge valgus osteotomy stabilized with a Puddu plate and bone grafting. The patients were evaluated with the Knee Injury and Osteoarthritis Outcome Score (KOOS) preoperatively and at three and six months, one, two, five and 10years postoperatively with a mean follow-up time of 8.

Helmet use and risk of head injuries in alpine skiers and snowboarders: changes after an interval of one decade.

Background: In a previous study, we concluded that a safety helmet can reduce the risk for head injury by 60%. Other studies reported similar effects, resulting in a general recommendation to wear a helmet while skiing or snowboarding.

Aim: To determine the effect of the expected increased helmet wear on the risk of head injury one decade after the recommendation.

Good functional results of distal femoral opening-wedge osteotomy of knees with lateral osteoarthritis.

Purpose: To evaluate the time-dependent functional outcome of patients with lateral knee osteoarthritis with increased valgus treated with lateral opening-wedge osteotomy to shift the load from the lateral to the medial compartment of the knee.

Methods: Twenty-four consecutive patients with lateral knee osteoarthritis were treated with distal femoral opening-wedge varus osteotomy stabilized with the Puddu plate and bone transplantation. The mean age of the patients was 48 years (CI 40.

Radiological outcomes in a randomized trial comparing opening wedge and closing wedge techniques of high tibial osteotomy.

Purpose: The aim of the present study was to examine changes in radiological variables in a prospective randomized study comparing opening wedge (OW) and closing wedge (CW) techniques of high tibial osteotomy (HTO). Our hypothesis was that there would be no differences in joint line angles or correction accuracy between the two groups, that patellar height would increase after CW HTO and decrease after OW HTO, and that leg length and posterior tibial slope would decrease after CW HTO and increase after OW HTO.

Methods: Radiological data were collected from 70 patients participating in an ongoing prospective randomized clinical trial comparing OW and CW HTOs.

All-inside suture device is superior to meniscal arrows in meniscal repair: a prospective randomized multicenter clinical trial with 2-year follow-up.

Purpose: Multiple techniques and implants are available for all-inside meniscal repair, but the knowledge about their failure rates and functional outcome is still incomplete. The hypothesis was that there might be differences between meniscal arrows and suture devices regarding reoperation rates and functional outcome. Thereby, the aim of this study was to compare clinical results following repair with the Biofix(®) arrows or the FasT-Fix(®) suture devices.

Functional improvements desired by patients before and in the first year after total hip arthroplasty.

Background: In the field of rehabilitation, patients are supposed to be experts on their own lives, but the patient's own desires in this respect are often not reported. Our objectives were to describe the patients' desires regarding functional improvements before and after total hip arthroplasty (THA).

Methods: Sixty-four patients, 34 women and 30 men, with a mean age of 65 years, were asked to describe in free text which physical functions they desired to improve.

Recovery and prediction of physical functioning outcomes during the first year after total hip arthroplasty.

Objectives: To investigate recovery of physical functioning in patients during the first year after total hip arthroplasty (THA), and to predict postoperative walking distance outcomes from preoperative measures.

Design: A longitudinal prospective design was used. Data were analyzed by repeated-measures analysis of variance and multivariate regression analyses.

Time-dependent improvement in functional outcome following Oxford medial unicompartmental knee arthroplasty. A prospective longitudinal multicenter study involving 96 patients.

Background And Purpose: 10-year survival rates after unicompartmental knee replacement (UKR) have been up to 97% in single-center studies, but they have been as low as 80% in studies from arthroplasty registers. Few studies have evaluated short-term functional outcome and its improvement with time. We determined the time course of functional outcome as evaluated by the knee injury and osteoarthritis outcome score (KOOS) over the first 2 years after Oxford medial UKR.

Effect of a walking skill training program in patients who have undergone total hip arthroplasty: Followup one year after surgery.

Objective: To investigate the effect of a 12-session walking skill training program of weight-bearing activities on physical functioning and self-efficacy initiated in patients 3 months after total hip arthroplasty (THA).

Methods: Sixty-eight patients with THA, 35 women and 33 men, with a mean age of 66 years (95% confidence interval [95% CI] 64, 67 years), were randomized to a training group (n = 35) or a control group without physiotherapy (n = 33). Assessments were performed before the intervention at 3 months (pretest), at 5 months (posttest 1), and at 12 months (posttest 2) after surgery.

Focal cartilage defects in the knee impair quality of life as much as severe osteoarthritis: a comparison of knee injury and osteoarthritis outcome score in 4 patient categories scheduled for knee surgery.

Background: Patients with focal cartilage defects in the knee may suffer from both pain and functional impairment. Treatment options are often insufficient. It is not known, however, to what extent their complaints affect quality of life, compared with other knee disorders.

Self-estimation of ability among skiers and snowboarders in alpine skiing resorts.

Skiing ability is thought to be an important risk factor for injuries, but the best method to classify skiing ability is not known. The objective of this study was to validate five different questions designed to self-report skiing ability for ski injury surveillance. To this end 512 alpine skiers, Telemark skiers, snowboarders and skiboarders were asked to selfestimate their skiing ability using five different questions based on skiing skill, piste difficulty, turning technique, skiing experience and falling frequency, each with four categories.

Helmet use and risk of head injuries in alpine skiers and snowboarders.

Context: Although using a helmet is assumed to reduce the risk of head injuries in alpine sports, this effect is questioned. In contrast to bicycling or inline skating, there is no policy of mandatory helmet use for recreational alpine skiers and snowboarders.

Objective: To determine the effect of wearing a helmet on the risk of head injury among skiers and snowboarders while correcting for other potential risk factors.

Articular cartilage lesions in 993 consecutive knee arthroscopies.

Background: Traumatic articular cartilage injuries heal poorly and may lead to development of osteoarthritis at a young age. This study estimates the number of patients who may benefit from one of the surgical methods of cartilage repair.

Methods: All patients undergoing knee arthroscopy during a 6-month period at three collaborating hospitals were consecutively evaluated according to the International Cartilage Repair Society (ICRS) knee form.
