Case ReportsFailed joint unloading implant system in the treatment of medial knee osteoarthritis.
In the setting of end-stage osteoarthritis of the knee, total knee arthroplasty is the gold-standard treatment. Recently, a minimally invasive, joint preserving treatment option in the treatment of medial osteoarthritis of the knee has been developed. ⋯ The goal of this novel device is to reduce medial compartment loading without significantly affecting the loading of the lateral compartment. In this context, the current authors present a case of device failure using these new implants, which at 7 months post-op necessitated revision surgery with complete removal of the device.

All arthroscopic release of the glenohumeral joint for severe frozen shoulder: initial glenohumeral visualization through trans-cuff portal.
In recent two decades, a novel minimally invasive technique for resistant frozen shoulder, arthroscopic glenohumeral release, has been popularly practiced. However, by far one key point, although being well recognized, has not been tackled at all during the procedure-that is how to safely and smoothly insert the arthroscope into contracted and restricted glenohumeral joint when MUA cannot be performed or work, especially the severe stiff shoulder. ⋯ Level IV, Case Series, Treatment Study.

Review Meta Analysis Comparative StudyTotal knee replacement following high tibial osteotomy versus total knee replacement without high tibial osteotomy: a systematic review and meta analysis.
Currently, there is no consensus as to whether total knee replacement(TKR) following high tibial osteotomy(HTO) provides similar postoperative outcomes as compared to TKR without previous HTO. Previous studies have provided limited evidence to small sample sizes and methodological inappropriateness. ⋯ Systematic review and meta analysis suggested that TKR following HTO provides similar outcomes as compared to TKR without previous HTO. Therefore, a previous HTO does not negatively influence a future TKR, though the conversion process of HTO to TKR is technically challenging. Systematic review also identified paucity in prospective and long term studies.

Case ReportsThe composite anterolateral thigh flap for knee extensor and skin reconstruction.
The simultaneous reconstruction of a skin defect and lost extensor mechanism of the knee joint is difficult. We present a 31-year-old male who lost the patella and had a 9 × 10 cm skin defect after a total patellectomy for an infected open patellar fracture. A composite anterolateral thigh (ALT) flap including vascularized skin and fascia lata (FL) was elevated. ⋯ Thirty months later, the active range of motion of the knee joint was 0°-120° and the extension strength of the knee joint was normal. He could stand on his right leg and walk without assistance. The composite ALT flap is a valuable option in knee reconstruction after a total patellectomy.

Cardiovascular effects of abduction shoulder sling in elderly patients; is it really safe?
The purpose of the prospective study is to investigate the cardiovascular effects of abduction shoulder sling (ASS) in elderly patients who underwent rotator cuff surgery. ⋯ ASS may trigger CSH in short necked and obese patients by exerting mechanical stimulation to the carotid sinus. These patients should be informed about symptoms and signs of CSH and educated on the proper use of ASS and correct positioning of shoulder strap. CSH should be kept in mind in patients who present with dizziness, presyncope and palpitation during the postoperative period.
