Annual trends in arthroscopic meniscus surgery: Analysis of a national database in Japan

Abstract

BackgroundThe importance of meniscus preservation is widely recognized. There have been a few studies describing trends in meniscectomy and meniscus repair in the United States; however, they presented differing results. We reported annual trends in meniscus surgery, using a national database in Japan.MethodsWe interrogated the Diagnosis Procedure Combination database, which represents approximately half of all hospital admissions in Japan. We included the patients who underwent meniscectomy and meniscus repair between July 2007 and March 2015. The diagnosis, age and sex of each patient were recorded.ResultsWe identified 83,105 patients: 69,310 underwent meniscectomy; 13,416 underwent meniscus repair and 379 underwent both in a single admission. The proportion of patients undergoing meniscus repair rose from 7.0% in 2007 to 25.9% in 2014 (p < 0.001), while the proportion undergoing meniscectomy fell from 92.8% in 2007 to 73.3% in 2014 (p < 0.001). Among patients under 30 years old, the proportions undergoing meniscus repair or meniscectomy in 2014 were 50.3% versus 48.3%, respectively. A bimodal age distribution was observed for meniscectomy, with peaks at 10–19 years of age and 60–69 years of age, whereas most patients undergoing meniscus repair were 10–19 years of age.ConclusionsWe found characteristic trends where the popularity of meniscus repair increased rapidly at the expense of meniscectomy in Japan during the study period. In the last survey year, the proportion of meniscus repair exceeded that of meniscectomy in those younger than 30 years. Meniscectomy was undertaken most often in adolescents and early old age, while meniscus repair was undertaken most often in adolescents.

National Trends of Meniscectomy and Meniscus Repair in Korea

“…With regard to age, in 2017, the highest peak was for patients in their 50s in terms of both total number of cases and incidence per 100,000 person-years, while the second highest peak was for patients in their 60s. Conversely, the highest peak was for patients in their 10s and the second highest peak was for patients in their 20s in Japan 1011. In the United States, the peak age was less than 25 years old and the second peak was between 25 and 34 years 9.…”

“…Similarly, according to another American study, meniscectomy (57% men vs. 43% women in 2011) and meniscus repair (60% men vs. 40% women in 2011) were performed more frequently in men than in women in the United States 9. In Japan, all meniscus surgeries, including meniscectomy and repair, were performed more frequently in men (52%) than in women (48%) over an 8-year period 11…”

“…Thus, the meniscus repair ratio showed a tendency to decrease as age increased. Kawata et al11 reported that the proportion of patients undergoing meniscus repair rose from 7.0% in 2007 to 25.9% in 2014, and the highest peak was noted for patients in their 10s while the second highest peak was noted for patients in their 20s. Katano et al10 reported that in Japan, the repair ratio was 19% in 2014 and 24% in 2015, and the highest peak in both years was for patients in their late teens.…”

“…The meniscus repair ratio was 19% in 2014 and 24% in 2015 10. Another Japanese study reported that the proportion of patients undergoing meniscus repair rose from 7.0% in 2007 to 25.9% in 2014, while that of patients undergoing meniscectomy fell from 92.8% in 2007 to 73.3% in 2014 11…”

Masažo ir kineziterapijos poveikis skausmui ir edemai po menisko operacijos

“…Japonijoje, atlikus 2007-2014 m. duomenų analizę, pastebėta, kad sparčiai padidėjo žmonių, kuriems atliktas menisko susiuvimas, ir smarkiai sumažėjo tų, kuriems atlikta meniskektomija, ypač jaunesniems. Meniskektomija dažniausiai buvo atliekama senyvo amžiaus žmonėms, o meniskai susiuvami paaugliams (Kawata et al, 2018). Dėl šių priežasčių norima išsiaiškinti, kokia yra optimali technika operuojant ir kokia pati geriausia pooperacinio laikotarpio reabilitacija.…”
