Failure of a TKA is caused many times from the polyethylene debris or the mechanical forces which lead to loosening mostly to tibial component. The mobile meniscal knee prosthesis could provide solution as it simulates better normal knee function.

The aim of our study is to present the midterm results of TKA using mobile bearing platform Rotaglide.

During the period 2000–2004 we performed 261 TKA with the Rotaglide mobile polyethylene prosthesis (Corin Medical, UK). They are 235 women and 26 men, mean age 76.33 years, and the 93.7% of them (N=245) with primary osteoarthritis. The tibial component was cemented for all them, and for the femur was cementless for 146 cases (hybrid) and cemented for 115. None of them had patella replacement. One hundred five patients (59 hybrid and 46 cemented) were examined clinically and radiologically and the minimum follow-up time was 5 years (mean 6,6 /range 5–8 years). We use the Knee injury and Osteoarthritis Outcome Score (KOOS- range of scale for each subscore 0–100).

There was significant improvement of knee function and the majority of our patients were satisfied from the result. Specifically, the score for general symptoms and joint stiffness was 89.1, for pain was 83.3, for daily activities was 75.6 and for the quality of life was 72.5. One patient had revision TKA for femur component aseptic loosening.

Our results indicate that the Rotaglide total knee arthroplasty is a great choice for primary knee OA with excellent functional result.

The bead EndoPearl is bioabsorbable material which placed in the ACL graft edge, and augment the stabilization in the femoral tunnel when an interference screw is used. Our aim was to recorded the operative characteristics of this technique and the clinical results after using EndoPearl in ACL reconstruction with hamstrings graft.

In 36 of our patients who had ACL reconstruction with hamstrings we used EndoPearl bead. They were 23 men and 13 women mean age 27.8 years (17–46). The graft was fixed in the femur side with interference screw. All patients followed the same p.o. rehabilitation regime. We followed them up the 1st, 2nd, 3rd, 6th and 8th p.o. month. During the last follow-up we checked the anterior drawer test, Noulis-Lachman test and in some cases pivot shift test, and in parallel Lysholm score was recorded pre-operatively and in the last examination.

In this last F.U. check none of them had positive Noulis-Lachman test or pivot shift test. The anterior drawer test was negative to 32 patients and in 4 we found slight laxity in comparison with the health leg. Lysholm score showed significant improvement (mean 90.2 p.o.), and nobody had “giving way”.

The application of the EndoPearl in conjunction with a bioscrew in the femoral tunnel in autogenous ACL reconstruction using semitendinosus and gracilis tendon grafts provides a significantly decreased in p.o. laxity.
