Synovial shelves of the knee: association with chondral lesions.
The objectives of the present study were to evaluate whether synovial shelves of the knee are associated with increased incidence of chondral lesions and to determine which types of plica are associated with significant articular damage. Data were collected prospectively from 1,000 consecutive knee arthroscopies. Of these patients, 321 (32.1%) were found to have synovial shelves of the knee. ⋯ In conclusion, synovial shelves of the knee are associated with an increased incidence of cartilage lesions. Larger shelves, particularly with chronic inflammation are associated with more frequently occurring and larger articular lesions. Areas with increased incidence of chondral lesions, in patients with plicae, include particularly the lower patella and the non-weight-bearing medial femoral condyle.

Tibial press-fit fixation of the hamstring tendons for ACL-reconstruction.
Press-fit fixation of patellar tendon bone anterior cruciate ligament autografts is an interesting technique because no hardware is necessary to achieve fixation. Up till the present point, there is no biomechanical data available for the tibial press-fit fixation of the hamstring tendons. Hamstring tendons of 21 human cadavers (age: 41.9 +/- 13.1 years) were used. ⋯ Only one technique (T) showed satisfactory elongation behavior during long-term cyclic loading. Interference screw fixation demonstrated significantly higher stiffness. Only one of the investigated techniques (T) seemed to exhibit adequate mechanical properties necessary for early aggressive rehabilitation programs.

Sclerosing polidocanol injections in mid-portion Achilles tendinosis: remaining good clinical results and decreased tendon thickness at 2-year follow-up.
The short-term results after treatment with sclerosing polidocanol injections have been shown to be good in patients with chronic painful mid-portion Achilles tendinosis. This study aimed to evaluate the longer-term effects on tendon thickness, structure and vascularity, patient satisfaction with treatment, and pain during tendon loading activity. Ultrasonography (US) + colour Doppler (CD) was used for evaluation of the tendon, and the patients graded the amount of pain during tendon loading activity on a VAS. ⋯ CD showed no, or a few, remaining neovessels in the majority of the successfully treated tendons. In conclusion, treatment with sclerosing polidocanol injections in patients with chronic painful mid-portion Achilles tendinosis showed remaining good clinical results at a 2-year follow-up. Decreased tendon thickness and improved structure after treatment, might indicate a remodelling potential?
