Comparative StudyFate of large donor site defects in osteochondral transfer procedures in the knee joint with and without TruFit plugs.
Because of the potential donor site morbidity, cartilage lesions of more than 3 cm(2) in size are considered to be critical regarding autologous osteochondral transplantation (OCT). In this study, the potential donor site morbidity for large defects should be reduced by means of OBI TruFit Plugs. ⋯ OCT is an effective therapy even for large chondral defects >3 cm(2). By filling the defects with TruFit implants, no clinical improvements could be found since the donor site morbidity was already low anyway. However, the regeneration of defects filled with TruFit implants took more than 2 years.

New modified Achilles tendon allograft for treatment of chronic patellar tendon ruptures following total knee arthroplasty.
Patellar tendon rupture is an infrequent but debilitating lesion. Several surgical repairs have been suggested for patellar tendon rupture. Our aim is to propose a modified technique from the classic Achilles allograft procedure. ⋯ The modified Achilles allograft has shown to be a safe, time-reducing repair for chronic patellar tendon ruptures following TKA, and should be considered as an alternative surgical repair.

Randomized Controlled TrialAdministration of enoxaparin 24 h after total knee arthroplasty: safer for bleeding and equally effective for deep venous thrombosis prevention.
The purpose of this study was to determine the safety and effectiveness, as assessed by risk of bleeding and incidence of deep venous thrombosis (DVT), of administering delayed low-molecular-weight heparin (LMWH) after total knee arthroplasty. ⋯ After total knee arthroplasty, LMWH-p is safer for bleeding than LMWH-s and equally effective concerning prevention of DVT.

Joint gap measurement in total knee arthroplasty using a tensor device with the same articulating surface as the prosthesis.
We developed a new tensor to measure the joint gap throughout knee flexion during total knee arthroplasty (TKA). This tensor has the same articular shape as that of the tibial liner, including the post structure and the curvature of femorotibial articular surface, to measure the gap intraoperatively under the same conditions as after TKA. The present study aimed to examine the precision of the new tensor for gap measurement after implantation. ⋯ The new tensor provides precise and reproducible measurements. Although the joint gap before implantation was parallel and equal at extension and 90° flexion, the joint gap after implantation was variable throughout knee flexion. This feature of the gap should be considered during the operation.

Observational StudyFunctional and radiological outcomes of semi-rigid dynamic lumbar stabilization adjacent to single-level fusion after 2 years.
To prospectively evaluate the functional and radiological outcomes of Isobar semi-rigid dynamic posterior stabilization adjacent to single-level fusion up to and including 24 months postoperatively. ⋯ Patients with single-level DLDI and mild adjacent level degeneration treated with Isobar stabilization show a clinical improvement after 2 years. However, disc degeneration at the index and adjacent levels seems to continue despite using semi-rigid dynamic stabilization.
