Arthroscopic meniscal repair evaluated by second-look arthroscopy.

Delaware Orthopedics Center, Wilmington.


Of 353 arthroscopic peripheral meniscal repairs performed using the "outside to inside" suturing technique with rasp preparation of the tear region, 74 repairs (50 medial and 24 lateral) were assessed by second-look arthroscopy and are the basis of this report. Results were graded as either healed, incompletely healed, or failed; these findings were correlated with clinical symptoms and associated ACL deficiency. Overall, asymptomatic healing occurred in 84%, with 65% healed and 19% incompletely healed. The failure rate was 16%. All failures were symptomatic while all healed and incompletely healed menisci were asymptomatic. Failure was associated with ACL deficiency in all cases. No failures occurred in either an ACL uninjured knee or an ACL reconstructed knee. Failure was also associated with tear location in the posterior horn of the medial meniscus. Eleven of 12 failures (92%) involved posterior medial meniscal tears with only 1 failure located posterolaterally. Visual evidence of healing required a 4 month time interval.
