The degree of damage to Holland’s knee is unknown but some experts agree that the pressure of weight on a freshly-operated knee can negate the surgery effort. This would warrant the use of crutches for up to six weeks after the operation. A rehab specialist may recommend either toe touch weight-bearing or non-weight bearing models as needed, but a check with the  online medical supplies provider is important to determine your size for the crutches.

Once you’ve been fitted with your crutches, you need to practice getting around with them attached; a knee brace may be set up to limit movement. For instance, you should keep the crutches as close to you as possible to allow your arms to withstand the weight bearing.
