ous sutures?

Background:

Quadriceps tendon rupture(QTR) is an invalidating injury typically

in need of surgical reinsertion. When dealing with ruptures at the tendon-bone

junction either transosseous sutures or anchor fixation are the most well de-

scribed methods for repair.

Purpose / Aim of Study:

The aim of this study was to compare these two

surgical methods by reviewing the current literature.

Materials and Methods:

A systematic search of the literature was performed

using MEDLINE, EMBASE and The Cochrane Central Register of Controlled Tri-

als to identify studies using either transosseous sutures or anchor fixation for

patients with QTR, with outcome measures being either extension lag, range of

motion, re-rupture or Lysholm score.

Findings / Results:

31 studies containing 163 patients were included, and di-

vided in to two groups based on surgical intervention, 10 studies containing

45 patients regarding anchor fixation and 22 studies containing 118 patients

regarding transosseous sutures. One study contained both interventions. In the

anchor fixation group 3 out of 46 QTRs (6.5%) had an extension lag. No pa-

tients had a range of motion <120° postoperatively and no re- ruptures were

reported. Average Lysholm score was 91,4. In the transosseous suture group 10

out of 83 QTRs (12.1%) had an extension lag, and 29 out of 95 QTRs (30.5%)

had a range of motion <120° postoperatively. 3 re-ruptures out of 145 QTRs

(2.1%) were reported. Average Lysholm score was 86.9.

Conclusions:

This study may indicate a slight advantage postoperatively re-

garding extension lag, range of motion, re-ruptures and Lysholm score when

operating QTR with suture anchors opposed to transosseous sutures. Given

a low patient count, mainly low evidence studies, and a differing amount of

patients in the two groups, further studies, preferably randomized controlled

studies, must be conducted.
