Is radiographic osteoarthritis associated with pain and disability of the ankle?

Objective: Ankle osteoarthritis (OA) is relatively understudied. It often affects younger people compared to OA in other joints. Evidence on the association between radiographic OA and ankle symptoms remains contradicting. We therefore examined the association of degree of radiographic talocrural, subtalar and talonavicular OA with severity of ankle pain, disability and predominant symptoms. Method: A cross-sectional study was conducted in a radiology department serving primary and secondary care. From the total study population (adults referred for ankle radiography), patients with chronic ankle complaints were selected (N â€‹= â€‹231). Before radiography, participants completed a questionnaire on severity of ankle pain and disability using the Ankle Osteoarthritis Scale (AOS), and on their predominant symptoms, i.e. pain, functional loss, stiffness and/or instability. To assess the associations of the Kellgren-Lawrence scores (0, 1 or ≥2) with the primary outcomes (AOS), linear regression, and with the secondary outcomes predominant symptoms, logistic regression analyses were applied. Results: Radiographic OA was not associated with AOS-pain and -disability. Radiographic talocrural OA was associated with functional loss (OR 3.26, 95% CI: 1.31; 8.11). A positive trend was seen between radiographic talonavicular OA and stiffness (OR 2.63, 95% CI: 0.97; 7.15). Conclusion: The presence of radiographic OA is not associated with severity of ankle pain and disability in patients with chronic ankle complaints referred for ankle radiography. However, radiographic talocrural OA is associated with functional loss and radiographic talonavicular OA with stiffness as predominant symptom. These findings may contribute to better recognition of ankle OA in clinical practice.

Prevalence of radiographic ankle osteoarthritis in different subgroups of patients referred for ankle radiography.

BACKGROUND: Ankle osteoarthritis(OA) has detrimental effects on physical health and has a relatively early disease onset compared to OA in other joints. However, the prevalence of radiographic ankle OA in different subgroups of patients referred for ankle radiography remains unknown. Therefore, we aimed to determine the prevalence of radiographic talocrural, subtalar and talonavicular OA(Kellgren-Lawrence scale ≥2) in a population referred for ankle radiography. Moreover, we aimed to identify differences in prevalence between specific subgroups of patients i.e. Body Mass Index (BMI), sex, age and reason for referral. METHODS: A cross-sectional study was conducted at a radiology department serving primary and secondary care. Patients completed a questionnaire before radiography. Features of radiographic ankle OA were assessed for subgroups of patients, including; BMI, sex, age and reason for referral (chronic vs (sub)acute complaints). To examine the difference in (features of) radiographic OA for subgroups, multinomial and logistic regression were used to calculate Odds Ratios (ORs), with adjustment for age, sex and BMI. RESULTS: Data from 893 patients that visited the radiology department across 16 months in 2017 or 2018 were included for analysis. Prevalence of radiographic ankle OA was 9.2%, 0.4% and 7.0%, for the talocrural, subtalar and talonavicular joint, respectively. Obesity was associated with radiographic talonavicular OA (adjusted OR 2.16, 95%CI:1.09; 5.26). Radiographic talocrural and talonavicular OA were both positively associated with male sex [(adjusted OR 4.64, 95%CI:276; 7.81) and (adjusted OR 1.95, 95%CI:1.13; 3.35), respectively]. CONCLUSION: Radiographic ankle OA was more common in men and obese patients that were referred to radiology.

Associations between biomarkers of matrix metabolism and inflammation with pain and fatigue in participants suspected of early hip and or knee osteoarthritis: data from the CHECK study.

OBJECTIVES: To assess the associations of biomarkers in serum [highsensitivity C-reactive protein (hs-CRP), serum cartilage oligomeric protein (sCOMP), serum propeptide of type I procollagen (sPINP) and serum osteocalcin (sOC)] and urine [urinary type II collagen telopeptide (uCTX-2)] with the extent and progression of nocturnal pain, pain while walking, and fatigue in participants with hip and/or knee pain suspected to be early stage osteoarthritis (OA). METHODS: hs-CRP, uCTX-2, sCOMP, sPINP and sOC were measured at baseline in 1,002 participants of the Cohort Hip and Cohort Knee (CHECK). Nocturnal pain, pain while walking and fatigue were assessed by self-reported questionnaires at baseline and 2-year follow-up. Associations between these biomarkers and symptoms were examined using logistic and linear regression analyses. RESULTS: hs-CRP was significantly associated with mild nocturnal pain (OR 1.18 95% CI 1.01-1.37), with mild and moderate pain while walking (OR 1.17 95% CI 1.01-1.35 and OR 1.56 95% CI 1.29-1.90, respectively) and with progression of nocturnal pain (OR 1.25 95% CI 1.07-1.46). uCTX-2 was associated with mild nocturnal pain (OR 1.40 95% CI 1.05-1.85) and with mild and severe-extreme pain while walking (OR 1.35 95% CI 1.04-1.75 and OR 2.55 95% CI 1.03-6.34, respectively). sPINP was associated with severe-extreme nocturnal pain (OR 0.45 95% CI 0.25-0.82). No significant associations were found for sCOMP and sOC, nor for any of the biomarkers and fatigue. CONCLUSION: This study of biomarkers in a large cohort of participants with hip and/or knee pain suspected to reflect early stage hip and/or knee OA suggests that inflammation and cartilage matrix degeneration play a role in pain, but not in fatigue.

Anatomical reconstruction of posterolateral corner and combined injuries of the knee.

PURPOSE: The goal of this study was to present a 2- to 5-year prospective follow-up of an anatomical posterolateral corner reconstruction in a series of 16 patients with symptomatic instability and pain complaints of the knee. METHODS: All 16 patients underwent a posterolateral corner reconstruction as described by LaPrade et al. If cruciate ligament ruptures were present and had not been addressed earlier, these were reconstructed as well. Preoperatively and 2-5 years after surgery, multiple subjective knee outcome scores (VAS satisfaction score, Tegner, Lysholm, Noyes score and IKDC subjective knee form) were obtained, and the laxity of the joint was evaluated objectively by using bilateral varus stress radiographs to compare the injured with the uninjured knee. RESULTS: Eleven patients had concomitant ACL or PCL surgery or already had undergone surgery on this cruciate ligament. Mean varus laxity of the injured knee on varus stress radiographs improved significantly from 9.6° (6.6-17.1) to 6.3° (0.3-13.4), p = 0.0011. Post-operative varus laxity did not return to the level of the uninjured knee: 4.4° (1.5-7.7), p = 0.036. VAS satisfaction score, the Tegner, Lysholm, Noyes scores and the IKDC subjective knee form all improved significantly. CONCLUSION: The anatomical reconstruction of the posterolateral corner does provide restoration of the external rotation stability in the majority of patients. However, the varus laxity could not be restored in all patients. Functional knee scores improved significantly, and most reconstructed knees had a laxity of <3° compared with the uninjured knee, but the reconstructed knee did not become as stable as the uninjured knee. The results of this study can assist surgeons and patients to have realistic expectations of this operation. LEVEL OF EVIDENCE: Case series with no comparative group, Level IV.

[Shoulder pain due to suprascapular neuropathy]. / Schouderpijn door suprascapularisneuropathie.

BACKGROUND: Shoulder complaints are caused by suprascapular neuropathy in 1-2% of patients. This rare condition is characterised by slowly progressing shoulder pain, which has as a consequence restriction of movement and loss of strength. The most frequent causes are tear of the rotator cuff or a space occupying lesion. CASE DESCRIPTION: A 30-year-old man presented with slowly arising shoulder pain with subsequent also loss of strength and atrophy of the shoulder. A MRI scan of the shoulder showed a cyst in the glenoid cavity. Using EMG suprascapular neuropathy was diagnosed. The cyst was removed by operation and the patient recovered well. CONCLUSION: The diagnosis 'suprascapular neuropathy' was made using EMG. Space occupying lesions of the shoulder can be excluded by X-ray and MRI. The treatment is primarily conservative, with physiotherapy and pain management.

A 31-year-old sailor came to the hospital with a bursted wound of his left hallux. Earlier that day, he had cut his left hallux and the wound had already been stitched elsewhere. On physical examination a dangling left hallux was observed and a ruptured tendon of the M. extensor hallucis longus.

Risk factors for lower extremity injuries among male marathon runners.

The aim of this study is to identify risk factors for lower extremity injuries in male marathon runners. A random sample of 1500 recreational male marathon runners was drawn. Possible risk factors were obtained from a baseline questionnaire 1 month before the start of the marathon. Information on injuries sustained shortly before or during the marathon was obtained using a post-race questionnaire. Of the 694 male runners who responded to the baseline and post-race questionnaire, 28% suffered a self-reported running injury on the lower extremities in the month before or during the marathon run. More than six times race participation in the previous 12 months [odds ratio (OR) 1.66; confidence interval (CI) 1.08-2.56], a history of running injuries (OR 2.62; CI 1.82-3.78), high education level (OR 0.73; CI 0.51-1.04) and daily smoking (OR 0.23; CI 0.05-1.01) were associated with the occurrence of lower extremity injuries. Among the modifiable risk factor studies, a training distance <40 km a week is a strong protective factor of future calf injuries, and regular interval training is a strong protective factor for knee injuries. Other training characteristics appear to have little or no effect on future injuries.

Prevalence and incidence of lower extremity injuries in male marathon runners.

The aim of this study is to describe the prevalence and incidence of lower extremity injuries occurring before and during the Rotterdam marathon, and to evaluate the impact of the injuries. A cohort study was compiled of recreational male participants in the 2005 Rotterdam marathon. Demographic data and information on previous injuries were obtained from participants using a baseline questionnaire. Information on injuries sustained shortly before or during the marathon was obtained from a post-race questionnaire. Seven hundred and twenty-five (48.3%) participants returned the baseline questionnaire. The 1-year prevalence of running injuries was 54.8%. In the post-race questionnaire, 15.6% of all respondents reported at least one new lower extremity injury in the month preceding the Rotterdam marathon. The incidence of lower extremity injuries occurring during the marathon was 18.2%; most of these injuries occurred in the calf, knee and thigh. Immediately after the marathon the median score of pain intensity at rest was 2 points vs 4.5 points during physical exercise. Hence we can conclude that running injuries are very common among recreational male marathon runners. However, the pain severity and consequences for work and daily activities seem to be relatively low 1 week after the marathon.

A multiple-dose comparison of ketorolac tromethamine with diflunisal and placebo in postmeniscectomy pain.

The efficacy of oral ketorolac 5 mg and 10 mg taken qid was compared in a randomized double-blind study with that of oral diflunisal 500 mg bid (interleaved with placebo twice daily) and of placebo, in 120 patients suffering at least moderate pain following meniscectomy. The trial comprised two phases: (1) an acute phase (the first postoperative day) and (2) a chronic phase (days 2-5 postoperatively). Acutely, pain was assessed before drug administration, and then 0.5, 1.0, 2.0, 3.0, 4.0, 6.0, 8.0, and 9.0 hours after the first dose. The second of the four daily doses was administered at four hours after the first dose. During the chronic phase, pain was assessed using visual analogue scales at 8 AM and 4 PM daily. The acute phase results show that all the active treatments were statistically significantly superior to placebo but were not distinguished from each other. Over the chronic phase, ketorolac 5 mg and placebo showed similar results, with diflunisal showing the least pain relief and ketorolac 10 mg the most. All the active treatments showed a low incidence of side effects and, in an overall evaluation, no one treatment was distinguishable. Ketorolac would seem to be an acceptable therapy for acute postoperative pain.

[A controlled clinical single-dose comparative study of suprofen and diflunisal]. / Eine klinisch kontrollierte Einzeldosis-Vergleichsstudie von Suprofen und Diflunisal.

In a single-dose, double-blind randomized study, the analgesic efficacy of suprofen 200, suprofen (alpha-methyl-4-(2-thienylcarbonyl)-benzene acetic acid; Suprol) 400 mg and diflunisal 750 mg capsules was determined in comparison to placebo capsules. A total of 130 patients participated in the study, all of them requiring analgesic treatment on the first post-operative day following meniscectomy. The treatment groups were homogeneous with respect to their demographic data. With the chosen pain model all active test substances were statistically significantly superior to placebo as far as pain intensity differences (SPID), pain relief (TOTPAR) and global evaluation of efficacy were concerned. Despite great differences in dosage and half-life, the active test substances must be regarded as equipment. Side effects were reported by 2 patients each in the diflunisal 750 mg and the placebo group, and by 1 patient treated with suprofen 200 mg.
