Objectives: We investigated the effect of prosthesis type on inpatient functional independence levels and length of hospitalization in patients undergoing total hip arthroplasty (THA).
Patients and methods: The study included 54 patients who underwent THA with a diagnosis of coxarthrosis. Conventional uncemented THA was performed in 27 patients (16 females, 11 males; mean age 64±12 years), and thrust plate prosthesis (TPP) was used in 27 patients (22 females, 5 males; mean age 60±15 years). Functional independence levels of the patients were determined with the use of the Functional Independence Measure (FIM) preoperatively and at the time of discharge.
Results: Compared to preoperative levels, FIM scores significantly decreased postoperatively in both groups (p=0.000). Patients undergoing TPP exhibited higher FIM scores both preoperatively and postoperatively than those treated with conventional THA, but these did not reach significance (p>0.05). However, the length of hospitalization was significantly shorter in the PPP group (conventional THA 14.3±5.3 days; TPP 13.2±6.9 days; p<0.05).
Conclusion: Our results show that the type of prosthesis does not affect inpatient functional results, with a slight difference of earlier discharge in TPP applications. Regardless of the prosthesis type, FIM scores significantly decrease following THA.
