Sports Activity Following Total Knee Arthroplasty in Patients Older than 60 Years
Section snippets
Material and Methods
In a retrospective follow-up clinical study, performed from November 2010 to September 2013, sports activity of 81 patients from an Alpine area was explored. Ninety-seven percent of these patients were sports active during live time. Patients were examined and questioned 6.4 ± 0.9 years after implantation of a total knee arthroplasty.
IRB admittance for the study has been obtained from the ethics committee of Freiburg University authorities November 16th 2010, admission number 346/10.

Results
A total of 74 patients (91.4 %) showed no effusion during clinical examination. Medial laxity was 2.8 ± 0.8 mm and lateral laxity was 2.6 ± 0.7 mm measured in 30° knee flexion. Evaluation of the range of motion of the investigated knee joints showed an average extension/flexion of 2° ± 1.1°/0°/120° ± 9.7°.
Discussion
According to literature patients younger than 60 years are showing higher sports activity compared to older individuals [13]. To reach a relatively homogenous group in possible sports activity the age group for the present study was selected between 60 and 80 years of life.
The current study shows that patients have taken up the previously applied sports to a large degree 6 years after total knee arthroplasty. At 1 year preoperative low-impact sports were preferred, and high-impact sports were
Conclusion
It can be concluded that in the selected study population 50% of patients were active in medium and low impact sports 6 years after total knee arthroplasty. A quarter of the patients were even active in high impact sports. At this time no individual showed evident signs of wear or component loosening. The long-term effect of high sports activity on the survival time of the prosthesis still remains unclear.
