5 points on hip resurfacing

Hip resurfacing has enjoyed a resurgence in popularity as an alternative to total hip replacement (THR) for the treatment of end-stage arthritis in younger, active patients. However, technical difficulties in implant positioning have been realized, as the procedure has been introduced amongst surgeons new to the concept. Furthermore, as the follow-up interval increases beyond the short-term, it is evident that certain issues with the metal-on-metal bearing surface may lead to complications. These 5 points on hip resurfacing are selected to highlight the factors that will help ensure an optimal outcome.

Efficacy of conservative treatment regimes for hip osteoarthritis--evaluation of the therapeutic exercise regime "Hip School": a protocol for a randomised, controlled trial

BACKGROUND

Hip osteoarthritis (hip OA) is a disease with a major impact on both national economy and the patients themselves. Patients suffer from pain and functional impairment in activities of daily life which are associated with a decrease in quality of life. Conservative therapeutic interventions such as physical exercises aim at reducing pain and increasing function and health-related quality of life. However, there is only silver level evidence for efficacy of land-based physical exercise in the treatment of hip OA. The purpose of this randomized controlled trial is to determine whether the specific 12-week exercise regime "Hip School" can decrease bodily pain and improve physical function and life quality in subjects with hip osteoarthritis.

METHODS/DESIGN

217 participants with hip OA, confirmed using the clinical score of the American College of Rheumatology, are recruited from the community and randomly allocated to one of the following groups: (1) exercise regime "Hip School", n = 70; (2) Non-intervention control group, n = 70; (3) "Sham" ultrasound group, n = 70; (4) Ultrasound group, n = 7. The exercise regime combines group exercises (1/week, 60-90') and home-based exercises (2/week, 30-40'). Sham ultrasound and ultrasound are given once a week, 15'. Measures are taken directly prior to (M1) and after (M2) the 12-week intervention period. Two follow-ups are conducted by phone 16 and 40 weeks after the intervention period. The primary outcome measure is the change in the subscale bodily pain of the SF36 from M1 to M2. Secondary outcomes comprise the WOMAC score, SF36, isometric strength of hip muscles, spatial-temporal and discrete measures derived from clinical gait analysis, and the length of the centre of force path in different standing tasks. An intension-to-treat analysis will be performed using multivariate statistics (group × time).

DISCUSSION

Results from this trial will contribute to the evidence regarding the effect of a hip-specific exercise regime on physical function, pain, and health-related quality of life in patients with hip osteoarthritis.

Feasibility of an exercise-based rehabilitation programme for chronic hip pain

BACKGROUND

Chronic hip pain is prevalent and disabling and has considerable consequences for the individual, and health and social care. Evidence-based guidelines recommend that patients with chronic hip pain benefit from exercise, but these guidelines are predominantly based on the efficacy of knee rehabilitation programmes. Studies investigating hip rehabilitation programmes suggest that these may not be feasible, citing issues with case identification. This study evaluated the feasibility of an exercise-based rehabilitation programme in a primary care hospital.

METHODS

Forty-eight participants with chronic hip pain were randomly allocated to receive a five-week exercise and self-management programme or to continue under the management of their general practitioner (GP). Participants were assessed at baseline, six weeks and six months. Outcome measures included Western Ontario and McMaster Universities osteoarthritis index physical function subscale, pain, objective functional performance, self-efficacy, anxiety and depression.

RESULTS

This programme was feasible, well tolerated and easily implemented into a primary healthcare facility. Adherence to the programme was high (81% attendance). Immediately following rehabilitation, all outcomes measures improved (effect sizes 0.2-0.4), although these improvements diminished at six months. There were no differences between the groups (all p > 0.05).

CONCLUSIONS

An exercise-based rehabilitation programme was found to be feasible and well tolerated by people with chronic hip pain. The moderate effects in all outcomes immediately following rehabilitation suggested that it warrants further investigation. Issues with diagnosis and adaptations to the programme were identified and will be addressed in a randomized controlled trial.

Resistance training in musculoskeletal rehabilitation: a systematic review

OBJECTIVE

To review the efficacy of resistance training (RT) as a therapeutic modality in various musculoskeletal conditions.

DESIGN

Systematic review.

SUBJECTS

Data from 1545 rehabilitation patients who had participated in structured RT programmes were included into the review. The total number of patients was composed of separate musculoskeletal conditions-chronic low back pain (CLBP) (549), tendinopathy (299), knee osteoarthritis (433), anterior cruciate ligament reconstruction (189) and hip replacement surgery (75).

RESULTS

Evidence suggests that RT can increase muscle strength, reduce pain and improve functional ability in patients suffering from CLBP, knee osteoarthritis, and chronic tendinopathy and those under recovery after hip replacement surgery.

CONCLUSION

RT can be used successfully as a therapeutic modality in several musculoskeletal conditions, especially those of a chronic variety. Although the exact application of training intensity and volume for maximal therapeutic effects is still unclear, it appears that RT guidelines, which have proven effective in a healthy population, can also be successfully applied in a rehabilitation context.

Systematic review and meta-analysis comparing land and aquatic exercise for people with hip or knee arthritis on function, mobility and other health outcomes

BACKGROUND

Aquatic and land based exercise are frequently prescribed to maintain function for people with arthritis. The relative efficacy of these rehabilitation strategies for this population has not been established.This review investigated the effects of aquatic compared to land based exercise on function, mobility or participants' perception of programs for people with arthritis.

METHODS

Medline, CINAHL, AMED and the Cochrane Central Register of Controlled Clinical Trials were searched up to July 2010. Ten randomised, controlled clinical trials that compared land to aquatic exercise for adults with arthritis were included. Study quality was assessed with the PEDro scale. Data relevant to the review question were systematically extracted by two independent reviewers. Standardised mean differences between groups for key outcomes were calculated. Meta-analyses were performed for function, mobility and indices that pooled health outcomes across multiple domains.

RESULTS

No differences in outcomes were observed for the two rehabilitation strategies in meta-analysis. There was considerable variability between trials in key program characteristics including prescribed exercises and design quality. Components of exercise programs were poorly reported by the majority of trials. No research was found that examined participant preferences for aquatic compared to land based exercise, identifying this as an area for further research.

CONCLUSION

Outcomes following aquatic exercise for adults with arthritis appear comparable to land based exercise. When people are unable to exercise on land, or find land based exercise difficult, aquatic programs provide an enabling alternative strategy.

[Rehabilitation of coxitis in patients with ankylosing spondylitis. Observations in a series of 30 patients hospitalized at the Rheumatology and Recovery Hospital of Iaşi]

The study aims to assess and compare the efficiency of two different kinetic programmes, in order to improve the treatment of patients with ankylosing spondylitis (AS).

MATERIAL AND METHOD

Our study included two samples (control and cases) of 30 patients admitted for AS and unilateral coxitis in the Clinic of Rheumatology and Medical Rehabilitation Iasi, between 2008-2009. Certain paramentres such as: age, body mass index, disease evolution, Schober test, index-earth test, inspir-expir index, BASDAI activity index, BASFI functional index, Health Assessment Questionaire (HAQ), pain, morning ankylosing inflammatory tests, and general state of health were assessed at every patient.

RESULTS

No variation with statistical significance were registered between the two samples. The Pilates method used in the rehabilitation treatment of patients with AS could have a favourable effect on indices regarding mobility, as well as patients' perception about their disease.

Efficacy of patient education and supervised exercise vs patient education alone in patients with hip osteoarthritis: a single blind randomized clinical trial

OBJECTIVE

To compare the efficacy of patient education and supervised exercise with that of patient education alone for the management of pain in patients with hip osteoarthritis (OA).

DESIGN

Single blind randomized clinical trial.

SETTING

Recruitment of patients from hospitals, primary health care and advertisement, Oslo, Norway.

PARTICIPANTS

109 patients with radiographic and symptomatic hip OA with mild to moderate symptoms.

INTERVENTIONS

Patient education (PE). Patient education and supervised exercise (PE+SE).

PRIMARY OUTCOME MEASURE

The pain subscale of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC pain).

RESULTS

No significant between group differences were found for WOMAC pain over the 16-month follow-up. Significant improvements were found for the secondary outcome WOMAC physical function (P=0.011) in the group receiving PE+SE compared to the group receiving PE only. No significant differences were found for WOMAC stiffness, the SF-36 subscales or the activity scale. The effect sizes (95% confidence interval) for WOMAC pain were -0.26 (0.11, -0.64), -0.35 (0.07, -0.77), and -0.30 (0.15, -0.75), and for WOMAC physical function -0.29 (0.09, -0.67), -0.48 (-0.06, -0.91), and -0.47 (-0.02, -0.93) at 4, 10 and 16 months, respectively, in favor of the group receiving both PE and SE. All patients attended the three-session PE program, and 75% performed ≥16 sessions of the 12-week SE program.

CONCLUSION

The study could not demonstrate a significant difference in pain reduction over time between PE+SE vs PE alone. Adding SE to PE may improve physical function, but the magnitude of possible benefit is unknown as the 95% confidence intervals around the mean difference were wide.

A review of the clinical evidence for exercise in osteoarthritis of the hip and knee

Osteoarthritis (OA) is a chronic joint disease with the hip and knee being commonly affected lower limb sites. Osteoarthritis causes pain, stiffness, swelling, joint instability and muscle weakness, all of which can lead to impaired physical function and reduced quality of life. This review of evidence provides recommendations for exercise prescription in those with hip or knee OA. A narrative review was performed. Conservative non-pharmacological strategies, particularly exercise, are recommended by all clinical guidelines for the management of OA and meta-analyses support these exercise recommendations. Aerobic, strengthening, aquatic and Tai chi exercise are beneficial for improving pain and function in people with OA with benefits seen across the range of disease severities. The optimal exercise dosage is yet to be determined and an individualized approach to exercise prescription is required based on an assessment of impairments, patient preference, co-morbidities and accessibility. Maximising adherence is a key element dictating success of exercise therapy. This can be enhanced by the use of supervised exercise sessions (possibly in class format) in the initial exercise period followed by home exercises. Bringing patients back for intermittent consultations with the exercise practitioner, or attendance at "refresher" group exercise classes may also assist long-term adherence and improved patient outcomes. Few studies have evaluated the effects of exercise on structural disease progression and there is currently no evidence to show that exercise can be disease modifying. Exercise plays an important role in managing symptoms in those with hip and knee OA.

Quality indicators indicate good adherence to the clinical practice guideline on "Osteoarthritis of the hip and knee" and few prognostic factors influence outcome indicators: a prospective cohort study

BACKGROUND

Evaluation with quality indicators of adherence to the clinical practice guideline on "Osteoarthritis of the hip and knee" and of treatment outcomes.

AIM

Furthermore to determine prognostic factors for outcome indicators.

DESIGN

Prospective cohort study.

POPULATION

Twenty-seven well informed physical therapists recorded patient and treatment characteristics of 103 community-dwelling patients referred by a general practitioner diagnosed with osteoarthritis of hip or knee.

METHODS

With selected process and outcome indicators adherences to the guideline and treatment outcomes were assessed. Prognostic factors were calculated for Algofunctional Index (AI) and Visual Analogue Scale (VAS) for pain (decreases of ≤25% indicating "poor outcome"), number of sessions (>12) and duration of treatment (>6 weeks), using multivariate logistic regression models.

RESULTS

Process indicators showed that information & advice was given to 95% of the patients and functions and activities were exercised in 97% respectively 87%. Aftercare was arranged for 46% of the patients, that was clearly lower than the benchmark of 90%. Outcome indicators VAS-pain and AI decreased by 45% and 36%, respectively. The combination ">12 months" duration of complaints and age ≥65" was associated with a "poor outcome" on AI (OR 2.53; 95% CI 1.01-6.38). Co-morbidity (OR 2.8; 95% CI 1.17-6.88), and "VAS-pain at baseline ≥51 mm" (OR 3.1; 95% CI 1.34-7.23) were associated with a higher number of treatment sessions.

CONCLUSION AND CLINICAL REHABILITATION IMPACT

and Quality indicators showed that a group of well-informed physical therapists could to a large extent adhere to key recommendations of the guideline and that clinically relevant improvements were obtained in terms of pain and physical functioning. Prognostic factors for poorer outcome on outcome indicators were comorbidity, a higher pain score at baseline and the combination ">12 months' duration of complaints and age ≥65".

The Hip and Knee Book: developing an active management booklet for hip and knee osteoarthritis

BACKGROUND

The pain and disability of hip and knee osteoarthritis can be improved by exercise, but the best method of encouraging this is not known.

AIM

To develop an evidence-based booklet for patients with hip or knee osteoarthritis, offering information and advice on maintaining activity.

DESIGN OF STUDY

Systematic review of reviews and guidelines, then focus groups.

SETTING

Four general practices in North East Wales.

METHOD

Evidence-based messages were developed from a systematic review, synthesised into patient-centred messages, and then incorporated into a narrative. A draft booklet was examined by three focus groups to improve the phrasing of its messages and discuss its usefulness. The final draft was examined in a fourth focus group.

RESULTS

Six evidence-based guidelines and 54 systematic reviews were identified. The focus groups found the draft booklet to be informative and easy to read. They reported a lack of clarity about the cause of osteoarthritis and were surprised that the pain could improve. The value of exercise and weight loss beliefs was accepted and reinforced, but there was a perceived contradiction about heavy physical work being causative, while moderate exercise was beneficial. There was a fear of dependency on analgesia and misinterpretation of the message on hyaluranon injections. The information on joint replacement empowered patients to discuss referral with their GP. The text was revised to accommodate these issues.

CONCLUSION

The booklet was readable, credible, and useful to end-users. A randomised controlled trial is planned, to test whether the booklet influences beliefs about osteoarthritis and exercise.

[Conservative treatment of hip and knee osteoarthritis: a systematic, step-by-step treatment strategy]

In the Netherlands the current, conservative management of osteoarthritis of the hip and knee is heterogeneous and suboptimal. Existing guidelines only provide indications for certain interventions, but they do not provide recommendations about the sequence of these treatments. A step-by-step treatment strategy has now been developed in addition to the guidelines. Its aim is to optimize and clarify the conservative policy for osteoarthritis. In addition, communication between patients and professionals and between professionals themselves must be encouraged. According to the treatment strategy, relatively advanced interventions are considered only after simpler interventions have had insufficient results. A care booklet has also been developed that contains information for patients about osteoarthritis, treatment options, healthcare professionals and the treatment strategy.

Effects of a sensory-motor exercise program for older adults with osteoarthritis or prosthesis of the hip using measurements made by the Posturomed oscillatory platform

OBJECTIVES

To assess changes in balance capacities after a 12-week sensory-motor training program for older adults with osteoarthritis or prosthesis of the hip.

BACKGROUND

Sensory-motor training is recommended to help aging adults with osteoarthritis maintain activity, avoid injurious falls, and improve functioning. Up to now, however, there has been no standard training protocol for sensory-motor training.

METHODS AND MEASURES

Thirty-five participants in a hip exercise group who had a mean age of 58 years (SD 12) were quasi-randomized into a training group (TG) and a control group (CG) by the month they applied for the Hip School program. The TG performed balance exercises using balance pads and received Hip School training once a week. The CG did not receive any training intervention. Balance was measured by recording center-of-pressure excursion while participants were in 1-legged stance on the oscillatory Posturomed platform. Outcome measures were the total path of center of pressure on the platform during balance recovery and the percentage of failed attempts.

RESULTS

The TG had a lower percentage of failed attempts (TG 5%, CG 18%, P = .001) and required fewer balance recovery movements to maintain balance (TG: mean [SD] measurement is 59 [36] mm; CG: 96 [68] mm, P = .036] after completing the 12-week training program. After the training period, participants in the TG compensated better for perturbations in the nondisplaced medial-lateral (ML) direction (pretest [SD] measurement was 48 [18] mm; posttest, 36 [14] mm; P= .001].

CONCLUSIONS

Participants could successfully cope with more disturbances and improved their reactions to sudden displacements after training intervention. This exercise setting improves balance abilities and should be included in Hip School programs for patients with osteoarthritis.

Conservative management of a young adult with hip arthrosis

STUDY DESIGN

Case report.

BACKGROUND

Clinical practice guidelines regarding the conservative management of degenerative hip conditions in older adults routinely incorporate therapeutic exercise and manual therapy. However, the application of these recommendations to young, active adults is less clear. The purpose of this case report is to describe the management of a young adult with advanced hip arthrosis using a multifaceted rehabilitation program.

CASE DESCRIPTION

A 28-year-old female with severe left hip degeneration, as identified with diagnostic imaging, was referred to physical therapy. Reduced hip range of motion and strength, sacroiliac joint asymmetries, and a modified Harris Hip Score of 76 were observed. She was seen for 12 visits over a 3-month period and treated with an individualized program including manual therapy, therapeutic exercise, and neuromuscular re-education.

OUTCOME

Substantial improvements were noted in pain, hip range of motion, and strength and function (modified Harris Hip Score of 97). In addition, she discontinued the use of anti-inflammatory medications and returned to her prior level of activity. Improvements were maintained at a 3-month follow-up, with symptom recurrence managed using a self-mobilization technique to the left hip and massage to the left iliopsoas.

DISCUSSION

Degenerative hip conditions are common among older adults but are relatively rare in the younger population. Although it is likely that this patient will experience a return of her symptoms and functional limitations as her hip disease progresses, the immediate improvements may delay the need for eventual surgical management. These outcomes suggest that physical therapy management should be considered in those with an early onset of degenerative hip disease and are consistent with results previously reported in the older population.

LEVEL OF EVIDENCE

Therapy, level 4.

Activity Increase Despite Arthritis (AIDA): design of a Phase II randomised controlled trial evaluating an active management booklet for hip and knee osteoarthritis [ISRCTN24554946]

BACKGROUND

Hip and knee osteoarthritis is a common cause of pain and disability, which can be improved by exercise interventions. However, regular exercise is uncommon in this group because the low physical activity level in the general population is probably reduced even further by pain related fear of movement. The best method of encouraging increased activity in this patient group is not known. A booklet has been developed for patients with hip or knee osteoarthritis. It focuses on changing disadvantageous beliefs and encouraging increased physical activity.

METHODS/DESIGN

This paper describes the design of a Phase II randomised controlled trial (RCT) to test the effectiveness of this new booklet for patients with hip and knee osteoarthritis in influencing illness and treatment beliefs, and to assess the feasibility of conducting a larger definitive RCT in terms of health status and exercise behaviour. A computerised search of four general medical practice patients' record databases will identify patients older than 50 years of age who have consulted with hip or knee pain in the previous twelve months. A random sample of 120 will be invited to participate in the RCT comparing the new booklet with a control booklet, and we expect 100 to return final questionnaires. This trial will assess the feasibility of recruitment and randomisation, the suitability of the control intervention and outcome measurement tools, and will provide an estimate of effect size. Outcomes will include beliefs about hip and knee pain, beliefs about exercise, fear avoidance, level of physical activity, health status and health service costs. They will be measured at baseline, one month and three months.

DISCUSSION

We discuss the merits of testing effectiveness in a phase II trial, in terms of intermediate outcome measures, whilst testing the processes for a larger definitive trial. We also discuss the advantages and disadvantages of testing the psychometric properties of the primary outcome measures concurrently with the trial.

Rehabilitation after total hip arthroplasty: a systematic review of controlled trials on physical exercise programs

Total hip arthroplasty (THA) has revolutionized the care of patients with end-stage joint disease, leading to pain relief, functional recovery, and substantial improvement in quality of life. However, long-term studies indicate persistence of impairment and functional limitation after THA, and the optimal rehabilitation protocols are largely unknown. The aim of this paper was to systematically review the controlled trials published on the effectiveness of physical exercise programs after THA. Nine studies were retrieved from MEDLINE and reviewed. Results show that the physical exercise protocols most frequently used after THA in the early postoperative phase are neither supported nor denied by clinical controlled trials. Convincing evidence for the effectiveness of single interventions in addition to usual exercise programs exists for each of the three following options: treadmill training with partial body-weight support, unilateral resistance training of the quadriceps muscle (operated side), and arm-interval exercises with an arm ergometer. In the late postoperative phase (operation interval > 8 weeks) exercise programs consistently improve both impairment and ability to function. Weight-bearing exercises with hip-abductor eccentric strengthening may be the crucial component of the late-phase protocols. Substantial limitations were found in the nine studies, including small sample size, patient selection, heterogeneity of outcome assessments, and potential sources of variability not investigated. Despite limitations, we conclude that three main suggestions emerge from controlled trials on physical exercise after THA: early postoperative protocols should include additive interventions whose effectiveness has been shown. Late postoperative programs are useful and should comprise weight-bearing exercises with hip-abductor eccentric strengthening.

A computer-adaptive disability instrument for lower extremity osteoarthritis research demonstrated promising breadth, precision, and reliability

OBJECTIVE

To develop and evaluate a prototype measure (OA-DISABILITY-CAT) for osteoarthritis research using item response theory (IRT) and computer-adaptive test (CAT) methodologies.

STUDY DESIGN AND SETTING

We constructed an item bank consisting of 33 activities commonly affected by lower extremity (LE) osteoarthritis. A sample of 323 adults with LE osteoarthritis reported their degree of limitation in performing everyday activities, and completed the Health Assessment Questionnaire-II (HAQ-II). We used confirmatory factor analyses to assess scale unidimensionality and IRT methods to calibrate the items and examine the fit of the data. Using CAT simulation analyses, we examined the performance of OA-DISABILITY-CATs of different lengths compared with the full-item bank and the HAQ-II.

RESULTS

One distinct disability domain was identified. The 10-item OA-DISABILITY-CAT demonstrated a high degree of accuracy compared with the full-item bank (r=0.99). The item bank and the HAQ-II scales covered a similar estimated scoring range. In terms of reliability, 95% of OA-DISABILITY reliability estimates were over 0.83 vs. 0.60 for the HAQ-II. Except at the highest scores, the 10-item OA-DISABILITY-CAT demonstrated superior precision to the HAQ-II.

CONCLUSION

The prototype OA-DISABILITY-CAT demonstrated promising measurement properties compared with the HAQ-II, and is recommended for use in LE osteoarthritis research.

A trial of the use of pedobarography in the assessment of the effectiveness of rehabilitation in patients with coxarthrosis

BACKGROUND

Pedobarography is an evidence-based diagnostic method that allows quantitative, qualitative and repeatable measurement of pressures on every square centimetre of the sole area of the foot as well as centre of gravity sway, with graphic and numerical recording of results. The aim of the study was to assess the progress of a selected model of rehabilitation on the basis of subpedal pressure distribution and centre of gravity sway in pedobarographic examination as well as to evaluate changes in pain intensity in patients with a history of coxarthrosis.

MATERIAL AND METHODS

The study included 21 patients with Altman grade 2 coxarthrosis. A postural pedobarographic examination was performed immediately before and after a 15-day course of rehabilitation with a PEL 38 electronic pedobarograph and computer image analyser with TWINN 99 software, version 2.08.

RESULTS

Following the rehabilitation, the study group displayed a statistically significant reduction in pain intensity, improved balance between the average and maximum subpedal pressures of both feet as well as a decrease in the velocity of centre of gravity sway.

CONCLUSIONS

1. A correlation between reduced pain intensity and improved balance of loads on both feet, as well as decreased velocity of centre of gravity sway were observed in the study group after the rehabilitation. 2. The pedobarographic examination may become a new method of diagnosis and follow-up in rehabilitation. 3. Pedobarography, owing to its ease of repeatability and non-invasiveness, may constitute a valuable attempt at objective monitoring of the progress of rehabilitation and its results. 4. The study results encourage further research based on a larger cohort of patients and a control group with a multi-stage prospective design.

[Rehabilitation of patients with post-traumatic coxarthrosis]

This paper reports the results of rehabilitative treatment of 102 patients with post-traumatic coxarthrosis. The data obtained during clinical and instrumental examination provided a basis for the development of a diagnostic algorithm that allows for objective verification of ethiopathogenesis of structural and functional disturbances in the supporting organ. An original approach is proposed based on distinguishing the principal clinical syndromes associated with post-traumatic coxarthrosis. Ways and means for medical rehabilitation of patients with post-traumatic coxarthrosis are reviewed with special reference to the mechanism of action of various therapeutic agents. Their combined application permitted to achieve a synergistic effect and thereby improve the functional outcome of remedial measures.

International Classification of Functioning, Disability and Health (ICF) core sets for osteoarthritis. A useful tool in the follow-up of patients after joint arthroplasty

AIM

The first aim of this study was to verify the applicability of the International Classification of Functioning Disability and Health (ICF) core set for osteoarthritis (OA) as an outcome tool after the total hip arthroplasty (THA) and total knee arthroplasty (TKA), in order to follow the changes of the profile of functioning after joint arthroplasty.

METHODS

Seventy-two OA inpatients were consecutively enrolled during the first three days of rehabilitation after THA (34.7%) or TKA (65.3%) and were evaluated of the ICF Core Set for OA. Patients were interviewed at the beginning of the study one month prior to surgery, at the end of the rehabilitation treatment lasting on average three weeks and three and six months after their discharge.

RESULTS

The ICF core set data comparison showed many significant differences among the four evaluations with a significant improvement in many categories assessed. At the six months interview activity limitations and participation restrictions were still reported, even if with a lower percentage as compared to the first evaluation.

CONCLUSION

The ICF core set for OA resulted an interesting outcome tool after the THA or TKA, even if more research is needed, mainly on data reliability and category definition. Even tough problems in the administration were encountered, the ICF core set allowed to focus on issues and aspects of patient's every day life usually not taken into account or not codified in the usual care assessment.

The benefit of modified rehabilitation and minimally invasive techniques in total hip replacement

INTRODUCTION

We wished to assess if an intensive rehabilitation regimen alone, or one combined with modified anaesthetic and surgical techniques, can change the speed of rehabilitation or the length of hospital stay after total hip replacement.

PATIENTS AND METHODS

We compared 44 patients who had followed a traditional care pathway, with 38 patients who had rehabilitated under a new rehabilitation protocol, with 40 patients who had also received modified, minimally invasive techniques. The speed of rehabilitation was measured in terms of three specific milestones accomplished on the day after surgery.

RESULTS

We found a statistically significant improvement in the day after surgery each activity was possible. The length of hospital stay was reduced from 6.5 days to 5.4 days to 4.1 days, a difference which was also statistically significant.

CONCLUSIONS

The data support the view that a new rehabilitation protocol alone can reduce the length of hospital stay and hasten rehabilitation. The combination of modified anaesthetic and minimally invasive surgical techniques with the new rehabilitation regimen can further improve short-term outcome after total hip replacement.

Long-term effectiveness of exercise therapy in patients with osteoarthritis of the hip or knee: a systematic review

OBJECTIVE

To determine the long-term effectiveness (>/=6 months after treatment) of exercise therapy on pain, physical function, and patient global assessment of effectiveness in patients with osteoarthritis (OA) of the hip and/or knee.

METHODS

We conducted an extensive literature search in PubMed, EMBase, CINAHL, SciSearch, PEDro, and the Cochrane Central Register of Controlled Trials. Both randomized clinical trials and controlled clinical trials on the long-term effectiveness of exercise therapy were included. The followup assessments were at least 6 months after treatment ended. Methodologic quality was independently assessed by 2 reviewers. Effect estimates were calculated and a best evidence synthesis was performed based on design, methodologic quality, and statistical significance of findings.

RESULTS

Five high-quality and 6 low-quality randomized clinical trials were included. Strong evidence was found for no long-term effectiveness on pain and self-reported physical function, moderate evidence for long-term effectiveness on patient global assessment of effectiveness, and conflicting evidence for observed physical function. For exercise programs with additional booster sessions, moderate evidence was found for long-term effectiveness on pain, self-reported physical function, and observed physical function.

CONCLUSION

The positive posttreatment effects of exercise therapy on pain and physical function in patients with OA of the hip and/or knee are not sustained in the long term. Long-term effectiveness was only found for patient global assessment of effectiveness. However, additional booster sessions after the treatment period positively influenced maintenance of beneficial posttreatment effects on pain and physical function in the long term.

Perceived exertion and rehabilitation with arm crank in elderly patients after total hip arthroplasty: a preliminary study

This preliminary study examined, in a restricted randomized trial, the effects of a 6-week arm-crank rehabilitation training program in elderly osteoarthrosis patients after total hip arthroplasty, first on physiological and perceptual responses and second on physical function. Two groups of patients were studied: a training group (N = 7, mean age = 74.9 yr, standard deviation [SD] = 5.0 yr) who followed a training program in addition to traditional rehabilitation, and a control group who followed traditional rehabilitation only (N = 7 mean age = 75.4 yr, SD = 5.1 yr). At the beginning of the training program, the heart rate and the perceived exertion were not significantly correlated during the exercise session. However, at the end of the training program, five patients had a significant heart rate/perceived exertion relationship (p < 0.05). Furthermore, positive effects of the arm-crank rehabilitation training program were observed on cardioventilatory and functional responses in the training group compared with the control group. These results suggest that after an habituation period, most of our elderly osteoarthrosis patients experienced physical sensations that were connected to physiological responses. Therefore, perceived exertion could be useful in these patients to regulate exercise intensity, especially at the end of and after the rehabilitation period.

Establishing recommendations for physical medicine and rehabilitation: the SOFMER methodology

OBJECTIVE

The development of a rigorous methodology based on published results of clinical trials, evaluation of daily practice in France and multidisciplinary expert opinion to elaborate recommendations for rehabilitation interventions.

METHODS AND RESULTS

The following describes the methodology of SOFMER (Société Française de Médecine Physique et de Réadaptation [French Society of Physical Medicine and Rehabilitation]) for developing recommendations for rehabilitation interventions. The test case was developing recommendations for rehabilitation in hip or knee osteoarthritis (OA) and hip or knee arthroplasty. Physicians in rehabilitation, orthopedic surgery and rheumatology identified, synthesized, and analyzed data from the literature by use of the usual French system of grading trials (the French Agency for Accreditation and Evaluation in Healthcare [ANAES] scale). The data were published results of comparative controlled studies such as randomized controlled trials, controlled clinical trials, cohort studies, case control studies, reviews of clinical trials, and case series, as well as uncontrolled cohort studies. The resulting recommendations were presented to the three annual French national congresses of rehabilitation, rheumatology, and orthopedic surgery for comment and for adapting to French professional practice. Finally, a panel of multidisciplinary experts (physicians in physical medicine and rehabilitation, rheumatologists, orthopedic surgeons, general practitioners, physical therapists, social workers, podologists, occupational therapists, nurses, and patients) validated the recommendations.

CONCLUSION

The SOFMER methodology could be an interesting tool for use in developing recommendations elaborated by all the concerned medical and surgical specialists in the wide domain of rehabilitation.

Strategies for the prevention and management of osteoarthritis of the hip and knee

Osteoarthritis (OA) is one of the most common forms of musculoskeletal disorders and incurs significant economic, social and psychological costs. OA increases in prevalence and also progresses with aging. Clinically OA is characterised by joint pain, crepitus, stiffness after immobility and limitation of movement. Many cases are 'idiopathic' (disease or condition of unknown course or which arises spontaneously), but OA can also be the end result of several other conditions or due to the combination of several other factors. There are various lifestyle factors that increase the risk of developing OA. Preventable or modifiable risk factors include obesity, occupational factors, sports participation, muscle weakness, nutritional factors and hormonal influence. Pharmacological therapies reduce pain and may reduce joint damage. Surgical interventions correct altered biomechanics to prevent OA. For severely damaged joints, partial or total replacement of the joint is possible for all of the large joints that are commonly affected by OA. OA is commonly associated with a limited function that can be improved with a wide variety of rehabilitative interventions: joint specific exercises, physical fitness, physical modalities. Education and self-management are very important to prevent overuse and to use the joints in the most adequate way.
