Objective:

To report on the feasibility and outcomes of total knee arthroplasty (TKA) combined with autologous distal femoral condyle graft for patellar reconstruction in a patient with post-traumatic knee ankylosis after patellectomy.

Key Findings:
  • Postoperative range of motion improved from 0°–15° to 0°–120° at 10 months.
  • Knee Society Score improved from 40 to 50 for pain and from 13 to 69 for function.
  • No clinical instability was observed postoperatively.
Interpretation:

Remove the entire section as it contains unsupported conclusions.

Limitations:
  • The study is based on a single case, limiting generalizability.
  • Long-term durability and advantages over TKA alone require further evaluation in larger studies.
Conclusion:

Revise to emphasize the need for further evaluation and avoid definitive statements about feasibility and outcomes.
