Mary is a 67 year-old who lost her left leg above the knee in 2011 from infectious complications following a total knee arthroplasty.

She was initially fit with a quadrilateral socket and locking gel insert and over the next 2 years she was fit with 3 different sockets:

  • Flexible ischial containment socket and locking gel insert
  • Suction skin fit ischial containment flexible socket
  • Suction socket over a seal-in gel insert

Mary had been reasonably successful with all of these sockets and functioned as a K3 ambulator, but she struggled maintaining her weight due to intestinal issues.  Consequentially, her residual limb volume fluctuated and problems escalated.  Mary’s difficulties with conventional fixed volume sockets presented as;

  • Excessive anterior brim pressure
  • Distal lateral femoral pressure
  • Proximal lateral gapping
  • Suspension slippage
  • Poor socket control despite multiple modifications

The CJ Socket Solution

In 2014 she was fit with a CJ Socket to address her limb volume issues and she has enjoyed great success maintaining a proper socket fit and improved control of the prosthesis.

Since the CJ socket uses cloth rather than hard plastic over its posterior section, Mary also reported remarkable improvements in her overall comfort, sitting comfort and flexibility.  She noted her pelvis was more level in sitting and she sat straighter.

She also enjoyed being able to rub or scratch her posterior thigh while wearing the CJ Socket and felt less disconnected to her residual limb.

The anterior brim remains more closely approximated to the inguinal ligament and Mary has found it easier to bend over to pick objects off the ground or tie her shoe.
