[Purpose]
A rupture of the quadriceps tendon is a severe
injury with a long recovery period and often
results in an extension lag and limitation of
flexion. The reconstruction of this tendon using
Leeds-Keio ( LK ) artificial ligament was firstly
reported by Fujikawa in 1994. The present study
aimed to reevaluate its clinical results.
[Patients and Methods]
Six knees in 6 patients (5 men and one woman;
average age 55.8 years, ranged from 43 to 67) with
rupture of the quadriceps tendon were involved in
this study. Two of the six cases were pathological
ruptures secondary to renal failure and Werner
syndrome.
The quadriceps tendon was reconstructed using
Leeds-Keio artificial ligament following Fujikawa’s
report. One day, or a few days after operation,
ROM exercise was started. Two or three weeks
after operation, partial weight-bearing in a brace
was permitted. Patients were followed for an
average of 1.8 years ( range, 3 months to 4 years ).
[Results]
In all patients, passive extension was 0 degrees.
The average of knee passive flexion was 143
degrees (ranged from 130 to 150). All patients
regained 90 degrees flexion within one month.
Two patients had no extension lag, and the other
four had an extension lag of less than 15. Within
5 months, two patients were able to play golf and
one to return to work as a taxi driver.
[Discussion]
Several procedures, involving end-to-end
anatomic repair and other reconstructions have
been described for repair of the quadriceps
tendon. However, most of these procedures
require cast immobilization and a long
rehabilitation since they have insufficient tensile
strength to allow early mobilization. Therefore,
such procedures have the potential to fail to
attain a good ROM.
The advantages of the reconstruction reported by
Fujikawa are that it is simple and enables a quick
start to ROM exercise without immobilization. In
our cases, all patients quickly gained good ROM
and remained little extension lag, some of the
patients were able to return to sporting activities
and to resume normal work within several
months. We concluded that reconstruction using
the LK ligament is an excellent procedure for
repair of a quadriceps tendon rupture.

Purpose: We used arthroscopy to evaluate
outcomes after surgery to repair intercondylar
eminence fractures. Material and methods: Ten
patients (8 men, 2 women; average age 27.9 years)
with fractures of the tibial intercondylar eminence
underwent an arthroscopic reduction and internal
fixation with non-absorbable sutures.
Preoperative radiological examination showed
that there were one Meyer’s type-II, eight type-IIIA
and one type-IIIB fractures. Clinical symptoms and
physical findings for all patients were evaluated
one year later. Radiographic assessment and the
Lysholm functional rating were also utilized. All
patients underwent second-look arthroscopy
when removing the fixation device. Arthroscopy
was used to assess the appearance of the surface
of the ACL, check for the existence of cyclops, and
look for interposition of tissue in the lateral and
medial joint spaces. Results: All patients achieved
bony union, and had negative Lachman and
anterior drawer tests. The average Lysholm knee
score was 94.5 points (100-75 points). Arthroscopy
showed an irregular surface on the ACL in 2 of 10
patients, cyclops in 2 patients, interposition in the
lateral joint space in 2 patients, and interposition
in the medial joint space in 1 patient. Two
