Comparison between tenocutaneous suture and Kessler suture techniques in treating acute closed Achilles tendon rupture

BackgroundTo compare the effectiveness of tenocutaneous suture and conventional Kessler suture techniques in treating acute closed Achilles tendon rupture.MethodsA total of 33 patients with acute closed Achilles tendon rupture who were admitted to our hospital from February 1998 to December 2008 underwent repair with either a tenocutaneous suture or Kessler suture technique. All patients were followed up for 1–5 years (mean, 3 years).ResultsAccording to the American Orthopaedic Foot and Ankle Society ankle–hindfoot scale, the excellence rate was 91% in the Kessler suture group and 98% in the tenocutaneous suture group, with a significant difference between groups.ConclusionOur tenocutaneous suture technique is an effective method for treating Achilles tendon rupture. It has certain advantages compared with the conventional incision method and is worthy of wide clinical application.     

Rupture of the Achilles tendon treated by a simple operative procedure

A subcutaneous suture technique for repair of closed rupture of the Achilles tendon first reported in 1977 is described again. The use of the technique in Aberdeen is compared with cases treated in plaster during the same 2-year-period. Although the total in the series is only 35, the results appear to indicate that the subcutaneous suture technique improves the power of plantar flexion without significant post-operative complications.     

A New Model for Repair of the Achilles Tendon in the Rat

ABSTRACT

The Sprague-Dawley rat is an excellent model for studies of Achilles tendon repair. Most researchers use a modification of the Kessler technique for suture repair of the Achilles tendon in rats. While this technique provides adequate strength, early mobilization is not recommended. Prior to healing, the load will be borne completely by the suture repair, subjecting it to rupture. To prevent this complication, investigators employing the Kessler repair often immobilize the operative extremity with a cast or splint. This has also been shown to be detrimental to the peak load borne by the tendons prior to rupture. A double-loop locking technique of suture repair for rat Achilles tendons is favored over the modified Kessler technique. As force is applied across the repair, the suture pulls on the tendon, sharing the load. This allows for early mobilization of repaired tendons, with minimal risk of rupture. Additionally, no immobilization is required for the operative extremity. One hundred repairs have been performed using this double-loop locking technique. All animals have been able to mobilize with minimal limp immediately after recovering from anesthesia, and there have been no ruptures. No other complications have occurred (hematoma, seroma, infection, dehiscence). This technique of tendon repair is ideal for use in studies of tendon repair in the rat, since it is easy to perform and eliminates the need for immobilization of the operative leg.

Augmentation vs Nonaugmentation Techniques for Open Repairs of Achilles Tendon Ruptures with Early Functional Treatment: A Prospective Randomized Study

A prospective randomized study was conducted in order to compare augmentation technique versus nonaugmentation technique, followed by early functional postoperative treatment, for operative repair of Achilles tendon ruptures. Twenty-four consecutive patients were assigned to two groups. Group I included 12 patients treated with Lindholm augmentation technique, whereas group II included 12 patients treated with modified Kessler end-to-end repair. Thereafter, these patients had postoperative management with a below-knee-cast for three weeks. The physioteraphy was initiated immediately after the cast was removed. Full weight bearing was allowed after five weeks postoperatively in the both groups. Two patients had reruptures in group II, whereas group I had prolonged operative time significantly. The patients with reruptures underwent reoperations and at the most final follow-up, it was observed that they could not resume to sporting activities. The other objective and subjective results were similar between two groups. Because of quite high rerupture rate in the group of patients treated with nonaugmentation technique, we favor functional postoperative treatment with early ankle movement in the patients treated with augmentation technique for the management of acute rupture of the Achilles tendon.

Key Points

• A prospective randomized study was conducted in order to compare augmentation technique versus nonaugmentation technique, followed by early functional postoperative treatment, for operative repair of Achilles tendon ruptures.
• Group I included 12 patients treated with Lindholm augmentation technique, whereas group II included 12 patients treated with modified Kessler end-to-end repair.
• Functional postoperative treatment with early ankle movement in the patients treated with augmentation for the management of acute rupture of the Achilles tendon is recommended.

Repair of flexor digitorum profundus tendon avulsions from bone: an ex vivo biomechanical analysis

Avulsions or distal transections of the flexor digitorum profundus tendon are typically repaired by direct suture of the tendon stump to the distal phalanx. The optimal repair technique to withstand in vivo rehabilitation forces is unknown. Our objective was to determine the time-zero tensile mechanical properties of 4-strand tendon-bone repair site constructs performed with 3-0 and 4-0 sutures and with modified Kessler and modified Becker grasping techniques. We hypothesized that the 3-0 modified Becker grasping suture technique not described previously for the reattachment of tendon to bone would show improved biomechanical properties compared with the 4-0 or modified Kessler techniques. All modified Kessler repairs failed by suture pullout from the tendon, whereas all modified Becker repairs failed by rupture of the suture at the tendon-bone junction. Although the 3-0 modified Becker repair group showed greater ultimate force then the other groups (p <.01), tendon-bone gap observed did not differ markedly between Becker or Kessler groups. Neither suture caliber nor repair technique had a notable effect on strain at 20-N force, suggesting that early gap formation at the tendon-bone repair site may occur regardless of technique.     

Augmented repair of acute tendo Achilles ruptures with gastrosoleus turn down flap

Background:

We present the results of primary repair of acute tendo Achilles (TA) rupture augmented with gastrosoleus turn down flap technique.

Patients and Methods:

78 consecutive patients with a complete acute rupture of the Achilles tendon operated between 1993 and 2004 were included in study. We performed a modification of the Lindholm technique in which the primary Kessler suture repair of the tendon was augmented by a turn-down ~3 cm × 10 cm gastrosoleus aponeurosis flap. In all cases, a short-leg circular walking cast was applied at 90° of the ankle dorsiflexion for 3 weeks and all the patients were encouraged to full weightbearing ambulation immediately. After removal of the cast, isometric and isokinetic ankle exercises were performed for 3 weeks. Modified Rupp Score was used to evaluate the subjective satisfaction.

Results:

All of patients returned to daily activity and 54 (69%) of them returned to previous sport activity. The tendon repair failed in two patients and they were reoperated with an allograft. Three patients developed infection and one of them required débridement. One developed deep venous thrombosis and two permanent sural nerve injuries were encountered. One of the patients had a severe skin necrosis, which was treated with rotation flap. The mean Rupp score was 29 (3–33).

Conclusion:

Primary repair of acute tendo Achilles rupture augment with gastrosoleus turn down flip technique in combination of immediate weightbearing ambulation provides a good outcome, but is associated with similar complication rates to the previous literature.
