formation is a serious problem after flexor tendon
repair. Many repair techniques have been developed to increase the suture strength after tendon repair
surgery. The purpose of this study was to assess adhesion
formation with different suture techniques in an in vivo canine model.
Sixty flexor digitorum profundus tendons were partially lacerated (80%) and repaired with either a modified Kessler (MK) or Becker (MGH) suture technique and supplemented with a simple running suture. The dogs were sacrificed at 1 week, 3 weeks, or 6 weeks after surgery and the repaired tendons were evaluated for adhesion
At 1 week there was no significant difference between the two repair groups (p
> 0.05). At 3 and 6 weeks, the adhesion
breaking strength in the MK suture group was significantly less than that of the MGH suture group (p
suture techniques may cause more adhesion
formation than the lower friction
suture techniques under passive postoperative therapy.
