Purpose : This study analyzes and compares the<br />
clinical result according to associated injuries in<br />
allograft meniscus transplantation.<br />
Materials and Methods : We retrospectively<br />
analyzed 36 knees in 35 patients who underwent<br />
allograft meniscus transplantation from 1999 to<br />
2003. Fourteen cases involved the medial<br />
meniscus, and 22 cases involved the lateral<br />
meniscus. The mean period from the total<br />
meniscectomy to the meniscus transplantation<br />
was three years and one month, the mean followup<br />
period was 2 years and 4 months, and the<br />
mean age of the patients was 32.5 years. Thirteen<br />
cases had an isolated meniscus deficiency (Group<br />
I), 5 cases were combined with injury of the<br />
anterior cruciate ligament (ACL) (Group II), 11<br />
cases combined with chondral defect (Group III),<br />
and 7 cases combined with both the injury of the<br />
ACL and the chondral defect (Group IV). The<br />
clinical results were evaluated using the Lysholm<br />
knee scoring system. Patients consented to<br />
arthroscopic second look evaluation of fifteen<br />
knees.<br />
Results : Regarding operative methods, 30 cases<br />
used a key hole method and 6 cases, for whom<br />
both reconstruction of the ACL and medical<br />
meniscus transplantation were performed<br />
simultaneously or in sequence, used a bone plug<br />
method. Out of 18 cases with chondral defect,<br />
additional autologous chondrocyte implantation<br />
was performed in 17 cases and the high tibial<br />
osteotomy in one case. The mean Lysholm knee<br />
scores improved 60.4 preoperatively to 93.1 at the<br />
latest follow-up. No statistically significant<br />
differences were found in Lysholm knee scores<br />
among the groups, between medial and lateral<br />
meniscus, and according to the operative<br />
methods. Two cases in Group I showed the<br />
problem of uneven tension in the transplanted<br />
allograft due to a size mismatch of the meniscus.<br />
The one case involving the high tibial osteotomy<br />
in Group III presented an intra-articular fracture.<br />
One case in Group IV demonstrated a<br />
postoperative partial ankylosis. Arthroscopic<br />
second look evaluation showed good or excellent<br />
peripheral healing in all cases.<br />
Conclusion : Allograft meniscus transplantation<br />
may be a viable option for the treatment of<br />
symptomatic patients with a meniscus-deficient<br />
knee. Patients whose injury is combined with a<br />
chondral defect or ligament instability should be<br />
treated with concomitant surgeries.<br />

Osteoarthritis After Total Menisectomy of the<br />
Medial, Lateral, Discoid Meniscus, and Medial<br />
Meniscus with Anterior Cruciate Ligament<br />
Injury<br />

Purpose : The purpose of this article is to analyze<br />
the clinical and radiologic results with patients<br />
who have undergone total menisectomy of the<br />
medial meniscus, lateral meniscus, discoid<br />
meniscus, and medial meniscus with anterior<br />
cruciate ligament(ACL) injury.<br />
Materials and Methods : Seventy-eight patients<br />
with 78 knees, who underwent total menisectomy<br />
between 1992 to 1998 and were followed up for at<br />
least 5 years, were evaluated. There were 16<br />
medial meniscus cases (Group I), 17 lateral<br />
meniscus cases (Group II), 29 discoid meniscus<br />
cases (Group III), and 16 medial meniscus cases<br />
with ACL injury (Group IV). The mean follow-up<br />
period was 7 years 2 months (range: 5 years to 11<br />
years 9 months). There were 54 men and 24<br />
women, aged from 10 to 39 years, who weighed<br />
from 36.5 to 103 kg. We exclude the cases which<br />
involved bilateral knees or both medial and lateral<br />
meniscus, had degenerative changes at the time<br />
of operation or mal-alignment, or whose weight<br />
was over 2 standard deviations for their age. For<br />
each group, functional and clinical results were<br />
evaluated with the Lysholm knee scoring system,<br />
and radiographic measurements were made with<br />
the Fairbank sign and the Alback classification<br />
system. The Kaplan-Meyer survivorship method<br />
was used for statistical analysis, while the knee<br />
joint space which narrowed over 50% (Alback<br />
Grade II) was defined as osteoarthritis.
