The 6H06A Single-Axis Knee Joint with Lock is designed for patients with low activity levels and a maximum weight of 125 kg. It is suitable for both unilateral and bilateral amputations at any level except knee disarticulation. This joint features a locking mechanism that locks the joint in full extension, thereby providing complete security during the stance phase. The joint design prevents any rollback during operation, a patented solution protected by the Russian Federation. The flexible lock cable can be installed on either the right or left side of the joint. This joint is available in versions with a pyramid adapter (6H06A1) and a clamp for a 30mm diameter tube (6H06A3).
