Knee osteoarthritis in 50 former top-level soccer players: a comparative study.

OBJECTIVES: To study the prevalence of knee osteoarthritis in a group of former top-level football players and to assess the condition's impact on joint function and structure, compared with a control group. MATERIALS AND METHODS: A cross-sectional, descriptive study was performed on a group of male former top-level football players (group G1), aged over 45 and with no history of knee trauma, arthritis, arthropathy or surgery. A second group of otherwise matched nonsporting subjects (group G2) was compared with the first group. For each subject, we specified age, weight, height, body mass index (BMI), dominant foot, the presence of knee axis deviation, the presence of pain and functional impairment. The pain level was assessed using a visual analogue scale (VAS). The functional assessment was performed using the Arabic version of the Lequesne index. Moreover, for each former player, we specified a number of sporting parameters, including those related to their playing career. The diagnosis of knee osteoarthritis was made using standard radiological and clinical criteria. The radiological severity of knee osteoarthritis was assessed using the Kellgren and Lawrence classification. We compared the two groups in terms of the frequency of knee osteoarthritis, the severity of pain and disability and the severity of structural impairment. RESULTS: Our study included two groups of patients: a group of 50 former football players (G1) with a mean age of 49.2. Overweight was noted in 40 subjects. The mean number of training hours a week was 14+/-3.5 during their professional career and 2.5 during their retirement. Half of the sportsmen had taken part in more than 200 matches. Knee axis deviation was observed in 29 former players (i.e. 58% of the cases) and 27 displayed genuvarum. A group of 50 nonsporting volunteers (G2) was matched to the G1 group in terms of age, BMI and frequency of axis deviation. Knee osteoarthritis was more common in the football players than in the nonsporting subjects (80% versus 68%), although the difference was not statistically significant. Whereas pain was noted in only six footballers (with an average VAS score of 25.4+/-6.3mm) and was observed in 50% of controls (with a mean VAS score of 39.2mm+/-7.3) (P=0.001). Disability was recorded in six sportsmen, with a mean Lequesne score of 0.38+/-1.27. Disability was more frequent (23 subjects) and more intense (with a mean Lequesne score of 1.71+/-3.2) in the nonsportsmen (P=0.001). The Kellgreen and Lawrence radiological classification revealed that 57.5% of the sportsmen had scores of III or IV, compared with just 29.4% in the control group. CONCLUSION: Knee osteoarthritis is common in male football players. However, our study shows that the condition is less painful and less likely to cause functional disability (but paradoxically more destructive) than in nonsportsmen.

[A long-term follow up of the shoulder in obstetrical brachial palsy]. / Suivi à long terme des épaules paralytiques obstétricales (à propos de 129 cas).

OBJECTIVES: To study shoulder impairment and disability caused by obstetrical brachial plexus palsy, their evolution under physical and surgical treatments, and the place of complementary explorations in persistent sequels. METHODS: From 1991 to 2000, 129 patients (66 M, 63 F) were included in a retrospective study. Impairment was assessed by muscle recovery (deltoid, biceps, external rotators) and shoulder passive motion. Disability was assessed by Mallet functional test. RESULTS: Full spontaneous recovery was noted in 20% of patients before the age of 3 months. Repair of the nerve lesion was undertaken in four children between the 18th and 24th months. Full recovery of deltoid and biceps was noted in three-fourth of whole cases before the 12th month, and of the external rotation in only 45% at this same age. Seventy-seven percent of patients showed stage >or= III of Mallet test (VI: 20%, IV: 32%; III: 25%) at a middle age of 3.5 years. A long-term follow-up showed an external rotation limited less than 20 degrees in 15 children. Investigation by RMN or Arthroscanner was realized for five patients, this reveals a deformation with subluxation of the humeral head in two cases. Ten children were operated (liberation of sub-scapula in nine cases associated to a tendinous transfer six times; humeral osteotomie in one case). This surgery has allowed the improvement of the functional state in all cases. CONCLUSION: After-effects in shoulder are frequent especially the limitation of external rotation, which can lead to a deformation, and subluxation of the humeral head. The authors insist on the importance to push investigations in case of limitation of the passive external rotation to improve the therapeutic choice.

[The contribution of capsular distension to the treatment of primary adhesive capsulitis of the shoulder: a comparative study versus rehabilitation]. / Apport de l'arthrodistension dans la prise en charge de la capsulite rétractile primitive de l'épaule : étude comparative versus rééducation.

OBJECTIVES: To describe the epidemiological and clinical features of patients with primitive adhesive capsulitis of the shoulder treated by capsular distension and then rehabilitation; to evaluate the short-, mid- and long-term efficiency of this therapeutic protocol and compare it with rehabilitation alone. MATERIALS AND METHODS: This was a two-year prospective study. Sixty patients were included and divided into populations P1 (capsular distension and rehabilitation) and P2 (rehabilitation only). Assessment of the treatments' efficacy was based on the following parameters: pain on a visual analogue scale (VAS), joint motion in several axes, a simplified Constant score (functional ability) and the SF-36 quality of life score. RESULTS: Thirty patients (mean age: 56) underwent capsular distension. The Constant score was judged to be poor in over half of the patients. All the quality of life parameters were modified. When compared with P2, the P1 group showed a statistically significant improvement in terms of the pain score (p=0.005), anterior elevation (p=0.001), lateral elevation (p=0.005), external rotation (p=0.006) and the Constant score (p<0.001) one week after capsular distension. One year after capsular distension, this gain persisted in a statistically significant manner for all functional parameters and all SF-36 dimensions (p<0.001 for PF, RP, BP, SF and RE; p=0.01 for GH and VT and p=0.002 for MH). CONCLUSION: Our results show that capsular distension and subsequent intensive rehabilitation have a beneficial effect. This combination enables rapid, significant improvement from the first week onwards. The improvement phase lasts for one month and may hold steady for up to 12 months.

[Strangulation of glans penis by hair or "penis tourniquet syndrome"]. / Strangulation du gland par cheveu ou "penis tourniquet syndrome".

The authors report 5 cases of strangulation of the penis with hair in children. This affection, more seen frequently within socially disadvantaged children, needs early diagnosis and treatment because it may be responsible for glans amputation. A better knowledge of this accident by parents and physicians might prevent this barbaric aggression.
