Background:
Meniscal tears are the most frequent pathology under the aus-
pices of the orthopedic department. As arthroscopic partial meniscectomy in-
crease the risk of degenerative changes in the knee, the focus of meniscal pre-
serving techniques has increased. Yet, Studies reveals that arthroscopic menis-
cal repair have an increased risk of reoperation compared to arthroscopic partial
meniscectomy.
Purpose / Aim of Study:
This study investigated whether environmental risk
factors, including Body mass index, sex, age and American society of anesthe-
siology score influenced the one year postoperative risk of reoperation after
arthroscopic meniscal repair.
Materials and Methods:
In this cohort design patients receiving arthroscop-
ic meniscal repair were retrospectively enrolled, by reviewing medical records
through 2011 to 2013. All Patients, older than 18 years of age, with an isolated
meniscal tear who underwent arthroscopic meniscal repair in this period were
included. Exclusion criteria were: No meniscal lesion, previous knee surgery, or
concurrent treatment of injuries in the knee joint including reconstruction of
cruciate, collateral or patella femoral ligaments, osteotomy, or treatment of a
tibia condyle fracture.
Findings / Results:
In total 289 menisci were included. A high BMI increased
the risk of reoperation with in the first year from primary operation. The inci-
dence of reoperation increased from normal weight to obese. Sex and age and
ASA-score did not have a significant influence on the risk of reoperation.
Conclusions:
BMI influences the risk of reoperation indicating that BMI have to
be taken into account in the attempt to lower the risk of reoperation in patients
receiving an AMR. In addition, ASA-score, age and sex did not have a significant
influence on the risk of reoperation.
