Clinical results of primary low contact stress cementless total knee arthroplasty.

The published clinical and radiographic outcomes data for primary cementless low-contact stress (LCS) total knee arthroplasty (TKA) were examined. The majority of patients (92.6%) were pain free or had only mild pain, and excellent or good knee scores (99.1%) at follow-up. Patella difficulties and significant radiolucent lines were rare, occurring in less than 1% of patients. The average range of motion (ROM) for patients without a history of previous knee surgeries was 112.1 degrees. Previous knee procedures had a negative impact on ROM. Overall, primary cementless LCS TKA achieves excellent clinical nd radiographic results.
