Resurfacing versus nonresurfacing the patella in total knee arthroplasty: a critical appraisal of the available evidence.

A systematic literature search for evidences comparing treatment effect and harm of resurfacing versus nonresurfacing the patella in total knee arthroplasty was conducted and yielded five meta-analysis (MA), one systematic review (SR) and six randomized controlled trials not included in previous MAs/SR. The evidence suggests that patellar resurfacing would reduce the risk of anterior knee pain, as well as the risk of patella-related reoperation. Furthermore, patients not undergoing patella resurfacing would experience more knee pain during stair climbing and be less satisfied with surgery.

Comorbidity-related quality of life in anterior cruciate ligament insufficiency: a cross-sectional study involving 282 candidates for arthroscopic reconstruction.

Background And Purpose: Comorbidity-adjusted health-related quality of life (HRQoL) in anterior cruciate ligament insufficiency (ACLI) has not been assessed to date. A cross-sectional study was conducted to test the hypothesis that HRQoL in ACLI is comorbidity-related and differs from the Italian norm.

Methods: 282 chronically ACL-insufficient candidates for arthroscopic reconstruction with or without meniscal and/or focal chondral lesions were studied.

Subcutaneous emphysema and pneumomediastinum following shoulder arthroscopy with brachial plexus block: a case report and review of the literature.

A number of complications are associated with shoulder arthroscopic surgery. However rare, respiratory complications such as pneumomediastinum and related tension pneumothorax as well as spontaneous pneumothorax in patients undergoing shoulder arthroscopy by endotracheal intubation have been reported in the literature. Although the exact pathogenetic mechanisms remain undetermined, surgery-related factors as well as associated respiratory comorbidity have been hypothesized to intervene in the onset of respiratory complications.

Arthroscopic all-inside suture of symptomatic Baker's cysts: a technical option for surgical treatment in adults.

Synovial fluid caused by repeated effusions may replete the gastrocnemius-semimembranosus bursa (GSB) communicating with the knee joint. Fluid trapped inside the GSB through an alleged unidirectional valve-like mechanism forms a so-called Baker's cyst. Since a significant association of Baker's cysts with knee joint disorders has been reported, treatment should primarily address articular lesions causing recurrent effusions.

A view from above: a modified Patel's medial midpatellar portal for anterior cruciate ligament arthroscopic surgery.

The use of flexible positions based on the surgeon's need to address specific pathology has been advocated in arthroscopic surgery. In this report we reappraise the midpatellar portals popularized by Patel and present a technique modification of the medial midpatellar portal (mMPP) focusing on its use in anterior cruciate ligament primary and revision arthroscopic surgery. The modified mMPP is established under arthroscopic control from a high anterolateral portal.
