In 2008, the French National Authority for Health (HAS) recommended that “conservative” treatments be adopted for meniscal lesions. This recommendation and the lack of superiority of meniscectomy over non-operative treatment for meniscus degeneration have modified the treatment pathway. However, the impact of these findings on French clinical practice is not known. The objective of this study was to evaluate the change over time in the number of alternative surgical procedures (meniscectomy and meniscus repair) and regional variation in France using data from the French agency for information on hospital care (ATIH).

We hypothesized that the number of meniscectomy procedures will decrease, and the number of repair procedures will increase over time at various healthcare facilities.

Between 2005 and 2017, the number of hospitalizations in the Medicine-Surgery-Obstetrics wards for meniscectomy (NFFC003 and NFCC004) or meniscus repair (NFEC001 and NFEC002) was evaluated overall and then based on whether the stay occurred in public or private sector hospitals in France. Data were extracted from the ATIH database and the findings were (1) related to French demographics during the period in question; (2) separated into public or private sector hospitals; (3) distributed into various regions in France and; (4) stratified by patient age.

Between 2005 and 2017, 1,564,461 meniscectomy and 63,142 meniscus repair procedures were done in France. Over this period in the entire country, the meniscectomy rate gradually decreased from 19.80/10,000 inhabitants in 2005 to 15.77/10,000 inhabitants in 2017 (21.4% reduction) (p<0.0001) while the meniscus repair rate increased from 0.42/10,000 inhabitants in 2005 to 1.36/10,000 inhabitants in 2017 (320% increase) (p<0.0001). The largest meniscectomy reduction effort occurred in private sector hospitals, going from 15.79 to 12.01/10,000 inhabitants in 12 years; the decrease was smaller in public hospitals (going from 4.01 to 3.77/10,000 inhabitants) (p<0.0001 in both cases). The change in the procedure ratio between private and public hospitals was asymmetric, with the meniscus repair/meniscectomy ratio clearly increasing more in public hospitals (4% to 12.6%) between 2005 and 2017 than in private hospitals (1.6% to 6.6%) (p<0.0001). We found large regional differences: regions in Eastern France had higher meniscectomy rates, while regions in Western France had higher meniscus repair rates. When the analysis of procedures between 2008 and 2017 was stratified by age, a similar increase in repair procedures was found in all age brackets. Conversely, the reduction in meniscectomy was most apparent before 40 years of age, and the number of meniscectomy procedures was stable after 60 years of age.

These findings suggest there has been a significant shift in the surgical management of meniscal injuries towards more conservative treatments. But the large variations between regions in France is evidence of a continued disparity in clinical practices.
