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 line 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%. Previous knee procedures had a negative impact on ROM. Overall, primary cementless LCS TKA achieves excellent clinical and radiographic results.
