Thetis Medical patient survey (n=195, Achilles tendon rupture).
Growing market
National registries report rising incidence (about 8 → 42 per 100,000, 1994–2021), linked to active ageing and sport.
- Large boot cohort in the first 12 weeks post-injury
- Strong night-splint attach — boot sleep is a common pain point
- Highest rates in Scandinavian and Western European data
Priority markets — incidence
Germany, France, Spain, Italy, Poland, and the Nordics are primary targets for national distribution. Incidence figures are from published registries and research in our global incidence report; where no national registry exists we show a conservative estimate.
| Market | Incidence | Est. annual ruptures |
|---|---|---|
| Nordics (SE, DK, FI) | ~35 / 100k | ~7,700 |
| Germany | ~25 / 100k | ~21k |
| France | ~21 / 100k | ~14.3k |
| Spain | ~19 / 100k | ~9,120 |
| Italy | ~20 / 100k | ~11.8k |
| Poland | ~16 / 100k | ~6,270 |

“Lighter at home than the boot — even used it in the pool”
After my Achilles rupture, I used the Thetis splint when I was home instead of wearing the heavy boot all the time. It made recovery easier, feeling a little more normal, while keeping the tendon safe. Also later I used it while swimming as it's light and easy in the water.
Holger Rune
Professional Tennis Player
“The Thetis splint was an absolute saviour”
After my Achilles tendon rupture surgery, I was advised by a specialist to invest in a Thetis splint as the best product to use as part of my recovery. The difference between sleeping in a big bulky boot and the Thetis splint was an absolute saviour. It made sleeping at night so much better and easier, and helped with my recovery as I was fresh because of better sleep. It kept my foot at the right angle and was light enough that I didn't notice it while asleep! I would and have recommended this product to my other teammates who have ruptured their Achilles tendon!
Steff Evans
Welsh Rugby Union Player
“Great for physio and a game changer for sleep!”
The Thetis splint was really helpful for staying safe when doing my rehab exercises. I've also been sleeping in it since I came out the cast which has been an absolute game changer.
Ollie Lawrence
English Rugby Union Player
“Revolutionary splint - comfortable sleep with no fear of injury”
I recently began using the Thetis Splint overnight. My regular boot is good for daily use but very heavy and uncomfortable to sleep in - the splint has been revolutionary for me! It keeps my foot perfectly in place but without being bulky, meaning I can sleep more comfortably with no fear of hurting my Achilles tendon. I would highly recommend everyone and anyone to use this product during your recovery from Achilles rupture.

“Slimmer, lightweight, and allows free movement while protecting the tendon”
The Thetis Splint is a lot slimmer and far more lightweight than the orthopaedic boot I was sleeping in. It allows me to move my leg more freely but still stops me from flexing my toes beyond a certain point, which is ideal whilst the tendon heals. The splint even comes in my favourite colour, so I was sold the minute I saw it!

“Simple design that allows better sleep and wound breathing”
The Thetis Splint has a simple design that is perfectly fit for purpose. It has allowed me to get the sleep that is so vital as I recovered from achilles tendon rupture and surgery whilst also feeling secure and protected. Apart from being less bulky than the orthopaedic boot, it also gives the surgical wounds a chance to breath and has made the recovery period a lot more bearable. I would highly recommend this product!

Patients
“Excellent service and delivery”
Excellent service and delivery. Loved the recovery tips. Love how this company has attention to detail, and looks after you.
“Total game changer for sleeping while recovering!”
Finally got the restful sleep I needed. The cast and heavy dirty boot made sleep tough. If you're recovering from an achilles rupture buy this immediately.
“It literally takes a few secs to put on and remove. Its comfortable as well. Highly recommend.”
Works great to keep the achilles tendon in relaxed state when recovering from a achilles injury or post-op. It literally takes a few secs to put on and remove. I've been using it for a couple of weeks now and its working well. I take my boots off for the night and wear this while sleeping. Its comfortable as well. Highly recommend if you are in the recovery stage of an achilles rupture post-op and out of the cast.
“Life Saver!”
This worked great and kept me from having to wear my big clunky walking boot to bed! So glad I found this. I couldn't sleep with that walking boot at night!! Great product.
“Eine absolute Erleichterung!”
Nach der OP an der Achillessehne war diese Schiene eine Erleichterung in der Nacht! Würde ich auf alle Fälle empfehlen wenn man wieder durchschlafen möchte!
“Superb”
Really useful after my dreadful Achilles tendon tear when I didn't want to wear the boot in bed!
“This is a saviour for night time wearing. So much easier than the big boot. Five weeks down and another five or six to go. Would have struggled with the full boot.”
This is a saviour for night time wearing. So much easier than the big boot. You need to be careful of getting up. I started using a crutch initially but as confidence grew just tried to ensure that I was careful. Five weeks down and another five or six to go. Would have struggled with the full boot.
“Peace of mind for Achilles injuries”
A great alternative to wearing the walking boot to bed, without worrying about inadvertently straightening or knocking your foot.
“Wonderful device and splendid service”
Brilliant device. Arrived the day after it was ordered. Delighted in all respects.
“Well designed product.”
This product is well designed. It gives good protection to injured Achilles' tendon whilst sleeping. Allows much better sleep compared to the pressure boot.
“Works well for sleeping and is definitely better than sleeping in the boot.”
I have the largest left splint, it works well for sleeping and is definitely better than sleeping in the boot — but your sizes are insane and there's no way it would ever fit properly. If I was based in the UK I'd have prob sent it back for being too small. There needs to be an XL at least. Anyway, keep up the good work.

Indications & contraindications
Intended use
- Achilles tendon rupture (complete tear)
- Surgical or conservative (non-operative) treatment pathways

Clinical evidence & NHS pathways
Our products are supported by clinical quality improvement work and real-world safety data — summarised on our public evidence page.
UK public healthcare — A&E and acute pathways
In UK NHS settings, the Achilles rupture splint is used in emergency and acute pathways to maintain plantarflexion while patients move from A&E to specialist review — reducing reliance on plaster rooms and speeding the pathway to a definitive boot and treatment plan. In other deployments it is supplied alongside our patient recovery course and educational materials (companion to the printed recovery guide where hospitals use it).

Night-time safety vs walking boot
Recovery-period safety assessment across 5,000+ patients recorded: with 95% confidence, risk of injury while using the Thetis splint at night is less than 0.1% — comparable protection to a walking boot with substantially better comfort for sleep (see Sleeping safe and sound, BOFAS 2024). Patient experience and satisfaction in recovery is reported separately in Mother Knows Best (BOFAS 2023).

“Als ich mir meine eigene Achillessehne riss, war das Schwierigste, den Krankenhausstiefel im Bett zu tragen. Diese Schiene wird das Genesungserlebnis für Patienten mit Sicherheit verbessern.”
Als ich mir meine eigene Achillessehne riss, war der schwierigste Teil der Genesung, den Krankenhausstiefel wochenlang nachts im Bett tragen zu müssen. Meine einzige Möglichkeit war, mir selbst eine Schiene aus Gipsmaterialien und provisorischen Gurten zu bauen. Es ist fantastisch, dass Thetis Medical diese Nachtschiene hergestellt hat. Sie wird das Genesungserlebnis für Patienten mit Sicherheit verbessern.
Mr James Davis
Ehemaliger Präsident der British Orthopaedic Foot and Ankle Society
“Ein Wendepunkt in meiner Praxis. Das Design der Schiene priorisiert sowohl Komfort als auch Funktionalität und ermöglicht eine kontrollierte, fortschreitende Genesung.”
Als Spezialist für Fuß- und Sprunggelenke bin ich immer auf der Suche nach innovativen Werkzeugen, die die Patientenergebnisse verbessern können. Die Thetis Medical Achilles Repair Splint hat sich in meiner Praxis als bahnbrechend erwiesen. Sie ist wirklich einzigartig, die einzige Schiene ihrer Art auf dem Markt, und ich habe sie mit großem Erfolg bei der Rehabilitation meiner Patienten nach Achillessehnenrissen eingesetzt. Das Design der Schiene priorisiert sowohl Komfort als auch Funktionalität und ermöglicht eine kontrollierte, fortschreitende Genesung. Meine Patienten berichten durchweg von weniger Beschwerden und besserem Schlaf, da sie die beschleunigte Entfernung der Immobilisierung in der Nacht sehr zu schätzen wissen. Die verstellbaren Merkmale ermöglichen eine individuelle Passform, die für die Anpassung an die spezifische anatomische Form des Beins jedes einzelnen Patienten unerlässlich ist. Ich habe die Thetis-Schiene als besonders effektiv empfunden, um die Lücke zwischen Immobilisierung und aktiver Genesung zu schließen. Sie bietet die notwendige Unterstützung, um eine frühzeitige Entfernung der Immobilisierung in der Nacht zu ermöglichen, was dazu beiträgt, Komplikationen durch unkontrollierte Bewegungen zu reduzieren und die Heilung zu beschleunigen. Ihre Langlebigkeit und Benutzerfreundlichkeit machen sie auch zu einer praktischen Wahl für Patienten und Ärzte. Ich empfehle die Thetis Medical Achilles Repair Splint Kollegen und Patienten gleichermaßen. Sie ist zu einem unverzichtbaren Bestandteil meines Behandlungsprotokolls geworden, und ich bin zuversichtlich, dass sie weiterhin einen neuen Standard in der Rehabilitation von Achillessehnen setzen wird.

“Patienten finden das Schlafen in einem Stiefel manchmal unbequem, und eine alternative, leichtere Option wird gut angenommen.”
Ich empfehle die Achillessehnenruptur-Schiene meinen Patienten seit über einem Jahr. Das Feedback war ausgezeichnet. Patienten finden das Schlafen in einem Stiefel manchmal unbequem, und eine alternative, leichtere Option wird gut angenommen. Meine Patienten haben sie auch verwendet, um den Fuß zu schützen und etwas Zeit außerhalb des Stiefels zu ermöglichen. Ich denke, es ist ein ausgezeichnetes Gerät, das die Genesung von einer schwierigen Erkrankung benutzerfreundlicher machen kann.
Professor Matthew Welck
Fuß- und Sprunggelenkchirurg
“Jeden Cent wert, da es das Elend beendet, in einem unbequemen Stiefel eine gute Nachtruhe zu finden!”
Ich empfehle die Thetis-Nachtschiene seit zwei Jahren allen meinen Patienten mit Achillessehnenriss. Sie ist jeden Cent wert, da sie das Elend beendet, in einem unbequemen Stiefel eine gute Nachtruhe zu finden!
Mr Ian Gill
Fuß- und Sprunggelenkchirurg
“Leicht und effektiv, bietet es Linderung im Schlaf und schützt den Fuß außerhalb des Stiefels.”
Die Thetis-Nachtschiene ist ein ausgezeichnetes Werkzeug zur Verbesserung der Genesung und des Patientenkomforts. Meine Patienten haben sehr positive Erfahrungen gemacht. Leicht und effektiv, bietet sie Linderung im Schlaf und schützt den Fuß außerhalb des Stiefels. Sehr zu empfehlen, um die Compliance und die Genesungsergebnisse zu verbessern.
Mr Sohail Yousaf
Fuß- und Sprunggelenkchirurg
“Es macht absolut Sinn, so etwas zu verwenden, und ich kann dieses Produkt nur wärmstens empfehlen. Rundum Komfort und Benutzerfreundlichkeit.”
Ich bin vor nicht allzu langer Zeit auf dieses Gerät gestoßen und habe das Gefühl, dass es meinen Patienten wirklich geholfen hat, sich von Achillessehnenrissen zu erholen. Es macht absolut Sinn, so etwas zu verwenden, und ich kann dieses Produkt nur wärmstens empfehlen. Rundum Komfort und Benutzerfreundlichkeit.
