None of what you mentioned meets the criteria, but you can still consult a physician for evaluation.
Additionally, it's important to assess whether the functional status aligns with the requirements.

More Info

After undergoing total knee replacement surgery, particularly in the context of a bone tumor, assessing disability certification can be a complex process. The criteria for disability certification often depend on the specific regulations of the jurisdiction in which you reside, as well as the extent of the physical limitations resulting from the surgery.
In the context of your question regarding the specific categories of lower limb disability (s750.1, s750.2, s750.3), let’s break down each category to assess whether you might qualify based on your condition post-surgery.

1. s750.1: Lower limb structure deficiencies above the ankle
- 1. One lower limb deficiency above the ankle: If you have had a total knee replacement, it is likely that you still have your ankle intact. Therefore, this criterion may not apply unless there are additional complications or deficiencies.

- 2. Complete deficiency of all toes on both lower limbs: This criterion is specific to toe loss. If you have not lost any toes, this would not apply.

2. s750.2: Lower limb deficiencies above the knee
- 1. One lower limb deficiency above the knee: If you have undergone a total knee replacement, you still possess the femur and the hip joint, so this criterion would not apply unless there are additional amputations or deficiencies.

- 2. Both lower limbs above the ankle: This would not apply if you have both legs intact, even if one has undergone surgery.

3. s750.3: Complete deficiencies of the lower limb
- 1. One lower limb completely absent from the hip joint: If you have had a total knee replacement, you still have your limb intact. Therefore, this criterion would not apply.

- 2. Both lower limbs above the knee: Again, if both limbs are intact, this criterion would not apply.

In summary, based on the information provided, it seems that you may not meet the criteria for the specific categories outlined (s750.1, s750.2, s750.3) as they pertain to complete deficiencies or amputations. However, it is essential to consider that disability assessments often take into account functional limitations rather than just structural deficiencies.
Post-surgery, you may experience limitations in mobility, strength, and endurance, which could impact your daily activities and quality of life. These functional limitations can be significant and may warrant a disability certification even if they do not fit neatly into the categories listed.
It is advisable to consult with your healthcare provider, who can evaluate your functional status and provide documentation that reflects your limitations. Additionally, a physical therapist can assist in assessing your mobility and strength, which can be critical in the disability evaluation process.
Ultimately, the decision regarding disability certification will depend on a comprehensive assessment of your overall health, functional capabilities, and the specific guidelines set forth by the disability certification authority in your area. It is crucial to provide all relevant medical documentation and assessments to support your case.
