Background:

Previous studies have observed a correlation between arthro-

scopic meniscectomy (APM) and accelerated progression on osteoarthritis, as

well as limited benefits of APM compared to arthroscopic meniscal repair (AMR)

and physiotherapy. Thus, the incitement for choosing APM as treatment for

meniscal lesions is questionable.

Purpose / Aim of Study:

To identify the distribution of AMR and APM over a

3-year period. In addition, the association between surgical procedure and the

following factors was investigated: age, gender, and traumatic or degenerative

lesion.

Materials and Methods:

In this Cohort Study medical records of patients who

had an APM or an AMR between 2011 and 2013 were evaluated retrospec-

tively. The total number of medical records was 1938 (56.1% men and 43.9%

women). Age ranged from 18 to 88 years, mean age 48.6 ± 15.5. The following

indicators were extracted from the medical records: age, gender, and whether

the lesion was traumatic or degenerative.

Findings / Results:

The incidence of AMRs has increased every year from

11.2% in 2011 to 18.1% in 2013. The mean age within the AMR group was

30.3 ± 10.4 and 51.8 ± 13.9 years within the APM group. Both groups were

male- dominant, however, the proportion of men were higher in the AMR group

compared to the APM group. The majority of the lesions in the AMR group was

traumatic (66.7%), whereas the majority of the lesions in the APM group was

degenerative (65.5%).

Conclusions:

APM is the most dominant surgical approach to meniscal lesions,

but the number of AMRs seems to increase every year. However, it remains un-

clear exactly how certain meniscal lesions should be treated in terms of harms

and functional outcome. In conclusion, the long-term outcome and predictors

to the outcome need to be evaluated further.
