Background
Failure of isolated primary meniscal repair must be expected in approximately 10–25% of cases. Patients requiring revision surgery may benefit from revision meniscal repair, however, the results of this procedure remain underreported. The purpose of this study was therefore to evaluate the outcome and failure rates of isolated revision meniscal repair in patients with re-tears or failed healing after previous meniscal repair in stable knee joints.Methods
A chart review was performed to identify all patients undergoing revision meniscal repair between 08/2010 and 02/2016. Only patients without concomitant procedures, without ligamentous insufficiency, and a minimum follow-up of 24?months were included. The records of all patients were reviewed to collect patient demographics, injury patterns of the meniscus, and details about primary and revision surgery. Follow-up evaluation included failure rates, clinical outcome scores (Lysholm Score, KOOS Score), sporting activity (Tegner scale), and patient satisfaction.Results
A total of 12 patients with a mean age of 22?±?5?years were included. The mean time between primary repair and revision repair was 27?±?21?months. Reasons for failed primary repairs were traumatic re-tears in 10 patients (83%) and failed healing in two patients (17%). The mean follow-up period after revision meniscal repair was 43 (± 23.4) months. Failure of revision meniscal repair occurred in 3 patients (25%). In two of these patients, successful re-revision repair was performed. At final follow-up, the mean Lysholm Score was 95.2 (± 4.2) with a range of 90–100, representing a good to excellent result in all patients. The final assessment of the KOOS subscores also showed good to excellent results. The mean Tegner scale was 6.8?±?1.8, indicating a relatively high level of sports participation. Ten patients (83%) were either satisfied or very satisfied with the outcome.Conclusion
In patients with re-tears or failed healing after previous isolated meniscal repair, revision meniscal repair results in good to excellent knee function, high level of sports participation, and high patient satisfaction. The failure rate is slightly higher compared to isolated primary meniscal repair, but still acceptable. Therefore, revision meniscal repair is worthwhile in selected cases in order to save as much meniscal tissue as possible.3.

Purpose
Return to sports rates in amateur and professional athletes with chronic patellar tendinopathy following arthroscopic patellar release are unpredictable. The present study aims to analyse the effectiveness of arthroscopic patellar release in professional compared to amateur athletes.Methods
A total of 34 amateur and 20 professional athletes with chronic patellar tendinopathy, refractory to conservative treatment, were studied prospectively and underwent arthroscopic tendon release at the inferior patellar pole. Impact of grouped sports on clinical and functional outcome, subjective patient satisfaction and return to sports rates were assessed. Additionally, preoperative MRI-scans of the knee were evaluated and correlated with clinical outcome.Results
In 40 patients (74.1%) arthroscopic patellar release resulted in complete recovery and return to preinjury exercise levels. Full return to sports was achieved after a median of 3.0 (range 0.5–12.0) months. Functional outcome measures VISA-P (Victorian Institute of sport assessment for patella) and modified Blazina scores improved significantly from pre- to postoperatively (VISA-P: 48.8 vs. 94.0 pts., respectively, p?<?0.0001; Blazina: 4.47 vs. 0.5, respectively, p?<?0.0001).Conclusion
As rapid recovery and timely return to sports are crucial for professional athletes, arthroscopic patellar release should be considered after failed conservative treatment.Level of evidence

Purpose
Presumably, the technique of SLAP refixation has significant influence on outcome. This study analyzes and compares functional outcome and return to sports after arthroscopic suture anchor (SA) and arthroscopic transglenoidal suture (TS) repair of isolated SLAP-2 lesions.Methods
Twenty-four competitive amateur athletes constituted the two treatment groups of this retrospective matched-pair analysis. In the SA group (n = 12), the mean age was 39.1 years (±12.0) and the mean follow-up period was 4.0 years (±0.6). In the TS group (n = 12), the mean age was 33.8 years (±12.0) and the mean follow-up period was 3.7 years (±0.9). The minimum follow-up period was 2.0 years. Primary outcome measures were the absolute constant-score (CS), the subjective shoulder value (SSV) as well as the ability to return to sports.Results
The mean CS in the SA group was 91.6 (±5.5) compared to 81.3 (±15.5) in the TS group (p = 0.04). The mean SSV after SA repair was 96.9 (±4.6) compared to 80.0 (±20.8) after TS repair (p = 0.01). Both scores showed significantly higher standard deviations within the TS group (p < 0.05). Twelve of eighteen patients (67 %) were able to return to their overhead sports without restrictions (5/9 in the SA group and 7/9 in the TS group; p > 0.05). Fourteen of twenty-four patients (58 %) achieved their preinjury sports levels (8/12 in the SA group and 6/12 in the TS group; p > 0.05).Conclusions
Superior objective and subjective shoulder function was obtained following arthroscopic SA repair compared to arthroscopic TS repair of isolated SLAP-2 lesions. In addition, results of SA repair were more predictable. However, nearly half of the athletes did not achieve full return to sports regardless of the applied technique of refixation. 相似文献7.

Purpose
The aim of the present study was to investigate the influence of knee flexion and weight bearing on the Tibial Tuberosity-Trochlear Groove (TTTG) distance.Materials and methods
Magnetic resonance imaging of the knee was carried out in 8 healthy volunteers. An open 0.25 T scanner equipped with a C-shaped permanent tilting magnet allowing examinations in weight-bearing conditions was used for the present investigation. A 3D gradient-echo sequence with axial slice orientation was obtained in a lying and an upright position with the knee straight and at 30° of knee flexion. The medial, central and lateral trochlear heights as well as the TTTG were determined.Results
The mean medial trochlear height was 76.2 ± 4 %, the central trochlear height was 72.2 ± 3 %, and lateral trochlear height was 82.9 ± 3 %. The mean TTTG distance was 11.6 ± 4.4 mm in lying position at 0° knee flexion and 7.3 ± 2.9 mm (n.s.) at 30° knee flexion. Under weight bearing, the mean TTTG was significantly smaller at both 0° knee flexion 6.3 ± 3.2 mm (p = 0.040) and 30° knee flexion 4.9 ± 3.9 mm (p = 0.006) compared to the lying position with 0° knee flexion.Conclusion
Tibial Tuberosity-Trochlear Groove distance depends on both knee flexion angle and weight bearing. The latter only seems to be of relevance in full extension. 相似文献8.
