The original questions was: recommendations on a very low clearance (KD with 4cm of tissue below tibial plateau) knee such as Total Knee combined with a terrain adaptive foot such as Proprio, Echelon, Motion foot, etc.
The concern was stability of the knee in reference to alignment supported by the foot on uneven terrain.
Most respondents suggested other knees with more inherent stability such as 3R60, Medi 4-bar knees, Nabtesco Symphony knee (6-bar), C-Leg and Symbionic leg. All of these are bulkier when sitting than Total knee, have greater overall clearance knee to floor and will not fit available space in patient's prosthesis. One primary objective is sitting clearance in a vehicle or church auditorium, which is where ST&G or Medi 4-bar, direct lamination knees are great, esp. when used with available locking function. These knees too, however, are not super stable. Also commented: there is a Proprio version in the works for use with TF prostheses as current Proprio is only set up for TT use. One other knee found: Proteor Matik knee with proximal M36 connection, similar to Total Knee, but longer bars and more posterior placed centre of rotation.
Thanks for all responses.
