Treatment of rupture of the Achilles tendon with fibrin sealant

Defining Components of Early Functional Rehabilitation for Acute Achilles Tendon Rupture: A Systematic Review

Background:

Early functional rehabilitation is frequently discussed in treating Achilles tendon rupture. A consistent definition of what constitutes early functional rehabilitation has not been established across the literature, despite studies supporting its efficacy. A standardized definition would be helpful to pool data across studies, allow for between-study comparisons, and ultimately work toward developing clinical guidelines.

Purpose:

To define early functional rehabilitation (including when it is initiated and what it entails) when used to treat Achilles tendon rupture and to identify outcome measures for evaluating the effect of treatment.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

Ovid MEDLINE, EMBASE, PEDro, CINAHL, and Cochrane databases were searched for relevant studies. Eligibility criteria for selecting studies consisted of randomized controlled trials, cohort studies, and case series (≥10 participants) including weightbearing or exercise-based interventions within 8 weeks after Achilles tendon rupture.

Results:

A total of 174 studies published between 1979 and 2018 were included. Studies were rated a median (interquartile range [IQR]) of 17 (15-20) on the Downs & Black checklist and included 9098 participants. Early functional rehabilitation incorporated weightbearing (95%), range of motion (73%), and isometric/strengthening exercises (50%). Weightbearing was initiated within the first week, whereas exercise (eg, ankle range of motion, strengthening, whole-body conditioning) was initiated in the second week. Initiation of exercises varied based on whether treatment was nonsurgical (mean, 3.0 weeks; IQR, 2.0-4.0 weeks) or simple (mean, 2.0 weeks; IQR, 0.0-2.3 weeks) or augmented surgical repair (mean, 0.5 weeks; IQR, 0.0-2.8 weeks) (P = .017). Functional outcomes including ankle range of motion (n = 84) and strength (n = 76) were reported in 130 studies. Other outcome domains included patient-reported outcomes (n = 89), survey-based functional outcomes (n = 50), and tendon properties (n = 53).

Conclusion:

Early functional rehabilitation includes weightbearing and a variety of exercise-based interventions initiated within the first 2 weeks after acute Achilles tendon rupture/repair. Because early functional rehabilitation has lacked a standardized definition, interventions and outcome measures are highly variable, and pooling data across studies should be done with attention paid to what was included in the intervention and how treatment was assessed.

Wound complications with posterior midline and posterior medial leg incisions: a systematic review

There is no consensus on the optimal incisional approach at the posterior leg to avoid wound healing complications. The purpose of this systematic review is to report and compare complication rates associated with two common incisions used to approach the Achilles tendon in order to provide additional recommendations for optimal incision placement.

MATERIALS AND METHODS

Four electronic databases were searched using keywords for procedures using posterior leg incisions. A total of 8724 studies were analyzed and subjected to inclusion and exclusion criteria. Once inclusion criteria were met, each article was placed in 1 of 2 groups based on incision placement: midline (group 1) or posterior medial (group 2). Study format, patient demographics, surgical indication and other details, and wound complications were recorded. The data obtained was reviewed for trends between the two groups.

RESULTS

38 articles met the inclusion criteria. Seven articles used the midline approach (group 1) whereas 31 articles used the posterior medial incision (group 2). The 38 articles included 1287 patients, of whom 25.6% were female with an average age of 43.9 years. Group 1 included 142 patients and group 2 had 1145 patients. The total wound complication rate among all reports was determined to be 8.2%, with 7.0% and 8.3% between groups 1 and 2, respectively.

DISCUSSION

Although incision placement may influence wound healing complications, it appears that additional factors such as advanced age, delay in surgical intervention, gender, comorbid conditions, prior surgery, and postoperative protocols also play a role. This report suggests that a midline approach is no less precarious in avoidance of wound complications regardless of patient demographics or other surgical details in comparison with a posterior medial incision.

LEVEL OF EVIDENCE

Therapeutic, Level IV.

Treatment of acute Achilles tendon rupture: fibrin glue versus fibrin glue augmented with the plantaris longus tendon

In the surgical repair of Achilles tendon ruptures, suturing is standard, although fibrin glue also has been used for repair since the 1980s. Augmentation with the plantaris longus tendon is also a popular technique; however, no study has yet compared the outcome of augmented versus only glued repair of ruptured Achilles tendons. This study compares the long-term results of surgical repair of Achilles tendon rupture with fibrin glue versus fibrin glue augmented with the plantaris longus tendon. Forty patients who had undergone Achilles tendon repair with fibrin glue took part in a follow-up examination after an average of 11.5 years. The fibrin group consisted of 16 patients and the fibrin glue augmented with plantaris longus tendon group consisted of 15 patients. The modified Thermann score (adapted from Weber) and results of an isokinetic force measurement were the same in both groups, whereas complications in the 2 groups also did not differ. We conclude that augmentation with the plantaris longus tendon is not necessary when operatively treating acute ruptured Achilles tendons with fibrin glue.
