Clinical outcomes in the revision of unicondylar arthoplasties to bicondylar arthroplasties. A matched-pair study.
The aim of the following study was to find out how much a previously implanted unicondylar prosthesis affects the clinical and functional outcome of a total knee arthroplasty in case of revision surgery. ⋯ Revision of an unicondylar to a bicondylar knee replacement showed inferior functional results in comparison to primary bicondylar knee arthroplasty. Patients are satisfied after conversion of an unicondylar to bicondylar prosthesis, but not quite as much as patients who received a primary bicondylar arthroplasty. However, in the small number of patients where revision surgery after failed unicondylar prosthesis is required, the patient had already been successfully treated for many years.

Low-severity metacarpal and phalangeal fractures treated with miniature plates and screws.
The results reported in the literature of metacarpal and phalangeal fractures treated with miniature plates and screws are scarce and contradictory. The aim of our study was to evaluate the functional results after low-severity metacarpal and phalangeal fractures treated by miniature plates and screws. ⋯ These very favourable results suggest that miniature plates and screws are a possible choice in the treatment of these fractures.

Case ReportsReconstruction of the greater trochanter with an allograft after resection of a giant cell tumor.
Our report involves the rare case of a giant cell tumor which filled out the greater trochanter. After complete resection of the greater trochanter, reconstructive surgery using a bone allograft was performed. Although the allograft healed without any complications, it was resorbed within 28 months, and there were no signs of infection or tumor recurrence during this period. ⋯ This shows that compensation for the missing greater trochanter is possible in adulthood. If the vasto-gluteal muscle sling is maintained, the greater trochanter, which would only function as a hypomochlion, may not be necessary. This is why we do not recommend reconstruction of the greater trochanter with an allograft when it is possible to maintain the tendineous junction between the vastus lateralis muscle and the gluteal muscles.

Patient outcomes following T-Fix meniscal repair and a modifiable, progressive rehabilitation program, a retrospective study.
This retrospective study presents clinical patient outcomes following meniscal repair using T-Fix devices and a modifiable, progressive rehabilitation program. ⋯ The T-Fix device used in combination with a modifiable progressive rehabilitation program produced excellent clinical patient outcomes among this patient group.

Comparative StudyBiomechanical and histologic comparison of Achilles tendon ruptures reinforced with intratendinous and peritendinous plantaris tendon grafts in rabbits: an experimental study.
We hypothesized that the closer the reinforcing graft was to the repair zone, the more strength the healed tendon would achieved. Therefore, we compared the ruptured rabbit Achilles tendons reinforced with intratendinous and peritendinous plantaris grafts. ⋯ In reinforcing Achilles tendon repair, the site of the tendon graft affected the result. When the graft was used intratendinously, the healed tendon was more similar biomechanically to normal tendon and had more graft-tendon orientation histologically than the tendon augmented peritendinously.
