Ninety-day complication rate based on 532 Latarjet procedures in Dutch hospitals with different operation volumes.

BACKGROUND: In this study, we aimed to provide insight into the 90-day complication rates following the Latarjet procedure. Data from 2015 were collected from multiple hospitals in the Netherlands, with different volumes of Latarjet procedures. Our second aim was to examine which patient and surgical factors were associated with complications. METHODS: We conducted a retrospective chart review of 13 hospitals between 2015 and 2022. Data regarding complications within 90 days of Latarjet procedures were extracted. The effect of sex, age, body mass index (BMI), smoking, previous shoulder operations, fixation material, hospital volume, screw size, and operation time on the complication rate was assessed by multivariable logistic regression analysis. RESULTS: Of the 532 included patients, 58 (10.9%) had complications. The most common complications were material failure (n = 19, 3.6%) and nerve injury (n = 13, 2.4%). The risk of complications was lower for male patients than for female patients (odds ratio, 0.40; 95% confidence interval, 0.21-0.77; P = .006). Age, BMI, smoking, previous shoulder operations, type of fixation material, hospital volume, screw size, and operation time were not associated with complications. CONCLUSION: The 90-day complication rate after the Latarjet procedure was 10.9% and was higher in female patients than in male patients. Age, BMI, smoking, previous shoulder operations, type of fixation material, hospital volume, screw size, and operation time did not affect complication rates. We advise setting up a national registry to prevent under-reporting of complications.

Successful conservative management of symptomatic bilateral dorsal patellar defects presenting with cartilage involvement and bone marrow edema: MRI findings.

The dorsal patellar defect is a relatively rare entity that involves the superolateral quadrant of the patella. It is usually considered to represent a delayed ossification process, although its exact origin remains unclear. Because of its usually innocuous nature and clinical course, invasive interventions are generally deemed unnecessary, although curretage has been successfully performed on symptomatic cases. This case report presents a rather unusual case of symptomatic bilateral dorsal patellar defects with cartilage involvement and widespread surrounding bone marrow edema as demonstrated by magnetic resonance imaging (MRI). Both cartilage involvement and bone marrow edema should be considered part of the spectrum of associated MRI findings that can be encountered in this entity. Furthermore, the presented case shows that symptomatic dorsal patellar defects can be treated conservatively with success and that (decrease of) pain symptoms are likely related to (decrease of) bone marrow edema.

The conceptually equivalent Dutch version of the Western Ontario Rotator Cuff Index (WORC)©.

BACKGROUND: The WORC is a quality of life questionnaire designed for patients with disorders of the rotator cuff, originally developed in English. The purpose of this study was to cross-culturally adapt the WORC for use in the Dutch population and to evaluate reliability, agreement and floor and ceiling effects of this Dutch version in a population of patients with rotator cuff disease. METHODS: Reliability was tested by measuring the Cronbach's alpha for internal consistency and intraclass correlation coefficients (ICC) for test-retest reliability. Agreement was measured using the Standard Error of Measurement (SEM(agreement)); and the smallest detectable change (SDC) was calculated based on the SEM. Pearson Correlations Coefficients were used to comparing the WORC with the RAND-36, the Constant Score and 11-point shoulder hindrance scale. RESULTS: Fifty-seven patients entered into this study of whom 50 were available for test-retest validation. The internal consistency of the Dutch WORC tested by Cronbach's alpha was 0.95 for the total questionnaire. The ICC for the WORC is 0.91 with a 95% confidence interval of 0.85-0.95. Standard Error of Measurement was 6.0 points with a Smallest Detectable Change of 16.7 points on a 0-100 scale. Pearson Correlations Coefficients showed a significant positive correlation between the Dutch WORC and Constant Score (r = 0.60) and a strong reversed correlation with the shoulder hindrance scale (r = -0.75). CONCLUSION: The Dutch WORC seems to be a reliable health-related quality of life questionnaire for patients with rotator cuff disorders. TRIAL REGISTRATION: NCT01532492.

Outcome of posterior ankle arthroscopy for hindfoot impingement.

PURPOSE: To provide short-term clinical results of posterior ankle arthroscopy in the treatment of posterior ankle impingement. METHODS: This was a retrospective evaluation of the clinical outcomes of posterior ankle arthroscopy in a series of patients with posterior ankle pain. RESULTS: Of 23 patients who underwent 24 posterior ankle arthroscopies between July 1998 and February 2004, 15 patients (mean age, 25 years) with 16 posterior ankle arthroscopies were evaluated at a mean follow-up time of 32 months (range, 6 to 74). Procedures carried out were: excision of os trigonum (11); decompression of prominent posterior talar process (5); tenolysis of flexor hallucis longus (5); removal of loose body (1); osteochondritis dissecans lesion debridement (1); and arthrotomy (1). The average time to return to work was 1 month (range, 0 to 3) and to sports, 5.8 months (range, 1 to 24). Fourteen patients returned to their preinjury level of athletics. Mean Health Survey Short Form (SF-12) scores were 51.80 for the mental component (range, 30.77 to 60.53) and 55.80 for the physical component (range, 44.26 to 63.33). Mean score on the American Orthopaedic Foot and Ankle Society Ankle and Hindfoot Scale was 91 (range, 77 to 100) and on the Lower Extremity Functional Scale was 75 (range, 65 to 80). Documented complications included temporary numbness in the region of the scar in 5 patients and temporary ankle stiffness in 1 patient. There were no permanent neurovascular injuries. All subjects reported significant improvement and indicated that they would undergo the surgery again if needed. CONCLUSIONS: Functional and clinical evaluations following posterior ankle arthroscopy revealed that all patients were very satisfied. They reported good to excellent health-related quality of life scores, satisfactory functional outcomes, and a high rate of return to sporting activities. Most importantly, no significant complications were encountered. This review suggests that posterior ankle arthroscopy is a safe and effective surgical procedure in the treatment of posterior ankle impingement. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
