Studies in Support of Non-Surgical Treatment of Achilles Tendon Ruptures

Historically, it was thought that the surgical approach was significantly superior to the non-surgical approach when treating achilles tendon ruptures.  Besides somewhat faster recovery times and somewhat better final outcomes in terms of leg strength, the key advantage of surgical treatment lay in significantly lower re-rupture rates.  On average, re-rupture rates after non-surgical treatment were around 20 percent (with a high of 40 percent!) and re-rupture rates from surgical treatment were around 5 percent or less in most studies.  See more on studies in support of surgical treatment of achilles tendon ruptures.

Although there were some older studies and findings that suggested much lower differences in re-rupture rates, it was not until 2008 and onward that major studies started coming out suggesting that non-surgical treatment was just as effective as surgical treatment.  Below is a list of studies and findings in chronological order that support non-surgical treatment.  The key factors in a successful outcome and low re-rupture potential from non-surgical treatment are functional bracing and early weight bearing and mobilization.


Bolded studies below are especially worth reading.

Older studies — I tend to ignore older studies that did not cover early weight bearing and mobilization, but for those interested, this article refers to a number of studies.   The earliest is from 1972 by Lea and Smith (1972), and continues with studies from Lildholt, Termansen, Nistor and more.

1988, Japan — 100 patients treated non-surgically and then monitored.

1993, Germany — 22 patients, regular ultrasonographic monitoring, “absence of complications and excellent functional results.”

2003, Switzerland — 23 patients treated conservatively between 1996 and 1998.

2004, UK — The famous Wallace report findings, 140 patients between 1992 and 1998.

2007, New Zealand — Twaddle,  1-year patient follow-up.

2009, Sweden — an excellent thesis by  Katarina Nilsson Helander. Also, an article with her findings.

2010, UK — Wallace, close to 1,000 patients treated conservatively between 1996 and 2008, only 2.8 percent re-rupture rate.

2010, Canada — 144 patients split evenly between surgery and non-surgery.

2012, UK — The important Devon & Exeter experience, 246 patients between 2008 and 2012.

2012, Sweden — 487 patient study of surgical and non-surgical patients treated between 2002 and 2006.  One to seven year post-treatment relatively long-term analysis.

2012, UK — a superb and huge two volume thesis by Rebecca Samantha Kearney.

May 2013, Netherlands — Very interesting summary of 576 patients treat surgically or non-surgically between 2001 and 2012, divided by early weight bearing (defined as within 4 weeks) and late weight bearing (defined as after more than 4 weeks).
