Knie Athletics

What Knie Athletics does

Knie Athletics (legal entity: MJS Sports GmbH) is a Germany-based digital healthcare provider specializing exclusively in knee injury rehabilitation, founded in 2021 and headquartered in Hohen Neuendorf near Berlin. The company delivers a premium, self-pay, fully digital rehabilitation program for individuals recovering from ACL tears, meniscus injuries, MCL injuries, and related knee conditions, with a focus on patients dissatisfied with standard German statutory health insurance-covered physiotherapy. The core product combines a proprietary 6-level progression methodology (the Knie-Level-System), a 60-minute initial functional analysis, weekly video-based movement analyses with angle measurements, criteria-based individualized training plans, and direct messaging access to specialized knee physiotherapists.

The platform is delivered exclusively online via smartphone-compatible applications, enabling nationwide German reach without physical clinic infrastructure. The company operates a sales-led GTM motion keyed off a free 20-minute consultation, followed by a free knee analysis call and conversion into a multi-month individualized program. Pricing is quote-based and not publicly disclosed because plans are tailored to injury type and severity; the company explicitly does not accept health insurance or physiotherapy prescriptions. The team is small (5-8 employees across two offices), bootstrapped with no external funding disclosed, and led by three co-founders (Steffen Schwarz, Marvin Hagendorf, Johannes Sommer) alongside a biomechanics PhD, state-certified physiotherapists, and coaches. To date, the company reports supporting 1,240+ knee injuries, with 1,200+ ACL/meniscus cases and 700+ completed programs.

Core offering

KNIEATHLETICS delivers digital knee rehabilitation coaching to individuals recovering from knee injuries such as ACL (cruciate ligament) tears, meniscus tears, MCL injuries, and other knee trauma. The core offering is a structured rehabilitation program that combines a proprietary 6-level progression system (Knie-Level-System) — moving patients from post-operative safety through sport-specific training — with weekly video-based motion analysis, criteria-based individualized training plans, and ongoing direct messaging support from knee-specialized physiotherapists, delivered entirely online.

Product overview

KNIEATHLETICS is a digital-first knee rehabilitation platform providing premium, personalized coaching for individuals recovering from knee injuries (primarily ACL and meniscus tears). The core offering is the KNIEATHLETICS Digital Knee Rehabilitation Program, which integrates five interconnected service modules: the Knie-Level-System (a proprietary 6-level progression framework from post-operative mobility to sport-specific return), Tiefgreifende Eingangsanalyse (comprehensive initial functional assessment), Wöchentliche Video-Bewegungsanalysen (weekly video-based movement analysis with time-lapse review), Kriterienbasierte Trainingsplanung (criteria-based individualized training plans with video instructions), and Engmaschige persönliche Betreuung (close personal coaching with direct physiotherapist access). All services are delivered exclusively digitally, enabling nationwide reach without geographic constraints.

Products and services

• KNIEATHLETICS Digital Knee Rehabilitation Program A premium, digital-first knee rehabilitation coaching service providing structured, criteria-based rehabilitation programs for individuals recovering from knee injuries (primarily ACL/cruciate ligament tears and meniscus tears). Delivered entirely online by knee-specialized physiotherapists via video analysis, personalized training plans, and direct messaging support.
• Tiefgreifende Eingangsanalyse (Deep Initial Analysis) An approximately 60-minute one-on-one functional analysis session with a knee physiotherapist that identifies mobility deficits, strength limitations, and movement pattern issues, followed by goal setting and creation of the patient's first training plan.
• Wöchentliche Video-Bewegungsanalysen (Weekly Video Movement Analyses) Weekly video-based movement analysis sessions that identify weaknesses in movement patterns using slow-motion playback and marking functions, enabling real-time training adjustments and objective progress tracking against Knie-Level-System test criteria.
• Kriterienbasierte Trainingsplanung (Criteria-Based Training Planning) Individualized training plans with specific exercise parameters (what, when, how) for rebuilding knee function across strength, mobility, stability, endurance, and speed, including video exercise explanations (Dos and Don'ts) and regular plan adjustments based on objective test criteria.
• Engmaschige persönliche Betreuung (Close Personal Support) Premium ongoing personal support with direct messaging access to knee physiotherapists and trainers, weekly feedback loops for plan adjustments, and rapid response to questions and uncertainties throughout the rehabilitation process.
• Knie-Level-System (Knee Level System) A proprietary 6-level structured rehabilitation progression framework that guides patients from the immediate post-operative/post-injury phase (Level 1: Secure Stand) through mobility, jumping and landing (Level 3), jogging and direction changes (Level 4), sprinting and stop-and-go (Level 5), to sport-specific training (Level 6: Focus & Sport-Specific). Each level has specific test criteria and movement goals, so progression is measured objectively rather than by elapsed time.

Quantifiable outcome

• Over 1,240 knee injuries successfully managed with testimonials showing return to skiing, climbing, football, half marathons, golf, hiking, and other activities.

Broad incumbents

• Hinge Health: Large US-headquartered digital MSK platform offering employer/payer-covered virtual PT, wearable sensors, and broad-joint coverage including knee. Comparable as the category-defining incumbent in digital MSK; Knie Athletics competes in the same knee-rehab sub-segment from a more specialized self-pay angle.
• Ottobock SE & Co. KGaA: Global German-headquartered leader in orthopedic prosthetics, braces, and rehabilitation technology. Comparable as a major incumbent player in the orthopedic and rehabilitation market; could be a potential strategic acquirer of specialized digital rehab capabilities like Knie Athletics.

Regional players

• Doctolib: Leading French/German telehealth and practice-management platform enabling online booking and video consultations. Comparable as a German-market digital health infrastructure player; not a direct rehab competitor but shapes the same patient acquisition channels and competitive landscape.
• medi GmbH & Co. KG: German medical device manufacturer specializing in orthopedic braces, compression therapy, and rehabilitation aids. Comparable because both serve German orthopedic patients recovering from knee injuries; medi is product-focused while Knie Athletics is service-focused, but they address overlapping patient journeys.

Direct peers

• Kaia Health: Germany-headquartered digital MSK therapy platform offering app-based exercise programs, coaching, and pain management. Direct peer because both deliver digital musculoskeletal rehabilitation digitally; Kaia is broader in scope but overlaps directly on knee/MSK rehab.
• SWORD Health: Portugal-based digital musculoskeletal therapy company combining AI motion tracking with remote PT sessions. Directly comparable because both deliver digital rehab with remote human therapist support and structured exercise programming for MSK conditions.
• Physitrack: Global digital exercise prescription and patient engagement platform used by physiotherapists. Comparable as a software layer enabling remote rehab program delivery, video exercise libraries, and outcome tracking; differs by being B2B infrastructure vs. Knie Athletics' DTC service model.
• Physiotec: Digital exercise prescription and patient home-program platform for physiotherapy clinics. Comparable as infrastructure enabling structured rehab programs with video exercises and progression tracking, addressing the same therapist-patient rehab workflow as Knie Athletics.
• Rehab My Patient: Digital exercise prescription platform for physiotherapists to build and assign home exercise programs with video tutorials. Comparable because both serve knee-rehab workflows with structured, criteria-based exercise plans delivered digitally to patients.

Emerging players

• Simple Therapy: Digital MSK rehabilitation platform offering remote PT and exercise programs. Comparable as a smaller-scale digital MSK peer; overlaps on knee rehab content delivery and remote coaching, though Simple Therapy tends toward B2B/employer channels.
