Statistics
The Wilcoxon test was used for comparison of
the preoperative and postoperative IKDC and
Tegner scores. The Mann-Whitney test was
used to compare the age of the patient, gender,
number of devices used, tear zone, tear stability,
and knee laxity between meniscal repair
failures and nonfailures. Kaplan-Meier curves
were used to visually illustrate differences in
time to reoperation between groups.
Significance was set at
P
<0.05.
Results
Population characteristics
We prospectively evaluated 132 consecutive
patients in whom 132 medial menisci met the
inclusion criteria and underwent a medial
meniscus repair through a posteromedial portal
in conjunction with ACL reconstruction. The
average age was 26.4 years (12-57), the average
BMI was 24.3 (16-34) with a male to female
ratio of five to one. The surgery was performed
in the right knee in 88 cases (66.7%). There
were 106 cases of primary ACL reconstruction,
23 cases of revision ACL reconstructions and
in 3 cases (2.3%) the procedure was a re-
revision procedure. For reconstruction, a
semitendinosus-gracilis tendon graft was used
in 89 knees (67.4%), a patellar bone-tendon-
bone graft was used in 41 knees (31.1%) and a
quadriceps tendon graft was used in 2 knees
(1.5%). The average side to side difference
anterior knee laxity measured with the
rolimeter (Aircast, Boca Raton, FL)
preoperatively
was
7mm
(5-14mm).
Preoperatively, the pivot shift test was normal
in 7 cases, had a “glide” in 65 cases, a “clunk”
in 23 cases and a gross pivot shift in 16 cases.
It was not possible to test the pivot shift in
21 cases. Characteristics of the suture are
summarized in table 1.
Objective and subjective evaluation
The mean follow-up period was 27 months
(range 24-29 months). 3 patients refused to
participate in the study and 6 patients had a
new severe traumatic event postoperatively,
resulting in 3 recurrent ACL tears, 2 contra
lateral ACL tears and 1 lateral meniscus tear.
These 9 patients reported no complaints about
the sutured meniscus but were excluded from
subjective IKDC final evaluation. The average
subjective IKDC rose from 63.8 ± 13.5 (range,
27-92) preoperatively to 85.7 ± 12 (range, 43-
100) at last follow up (
P
<0,0001). The Tegner
activity scale at the last follow-up (6.9 ± 1.72)
was slightly lower than before surgery (7.2 ±
1.92) (
P
=0.0017). The rolimeter test decreased
from a side to side difference in anterior knee
laxity of 7mm (range, 5-14mm) to a mean
value of 0.4mm (range: -3mm ± 5mm) at last
follow up (
P
<0,0001). 82.2% of the patients
returned to their premorbid level of activity.
Clinical failure
Unhealed tears
15 patients were found to be symptomatic
according to Barret’s criteria. An MRI was
performed in all cases. The tear appeared to be
healed in 3 cases and unhealed in 12 cases.
12 patients were considered as clinical failures
(positive Barret’s criteria and unhealed tear on
MRI examination). Clinical failure rate was of
9%. It was of 4.9% in the sub-group “limited
tear” and 15.7% in the sub-group “extended
tear”. The extended lesions had an increased
risk of clinical failure (
P
=0.036). 3 patients
considered their symptoms were not so intense
as to require revision surgery and only
9 patients underwent a revision surgery.
Need for revision surgery
The primary outcome in this study was the
need for reoperation on the repaired meniscus.
9 patients (6.8%) had failure of the meniscal
repair. 3.7% (3/81) occurred in the in the sub-
group of “limited tears” and 11.7% (6/51) in
the sub-group “extended tears” (fig. 3). With
repeat surgical intervention involving resection
or revision of the repair as the end-point, the
