Surgical Considerations in Managing Osteoporosis, Osteopenia, and Vitamin D Deficiency During Arthroscopic Rotator Cuff Repair.
Entezari, V, Lazarus, M
The Orthopedic clinics of North America. 2019;(2):233-243
Abstract
Osteopenia and osteoporosis are common in older adults and are associated with increased risk of fragility fractures. Vitamin D deficiency caused by chronic disease, poor nutrition, and inadequate sun exposure affects bone quality. Chronic rotator cuff tears can deteriorate the bone mineral density of the greater tuberosity and have been linked to reduced anchor pullout strength and high re-tear rate after repair especially in older patients with larger tear size. This article summarizes the current evidence on rotator cuff tear and bone quality and provides treatment strategies for rotator cuff repair in patients with poor bone quality.

Abstract
Ossifying tendinitis (OT) is a type of heterotopic ossification, characterized by deposition of hydroxyapatite crystals in a histologic pattern of mature lamellar bone. It is usually associated with surgical intervention or trauma and is more commonly seen in Achilles or distal biceps tendons, and also in the gluteus maximus tendon. To our knowledge, there is no description of OT as a complication of calcifying tendinitis of the rotator cuff. In this report, we describe two cases in which the patients developed an OT of the supraspinatus after arthroscopic removal of calcium deposits. The related literature is reviewed.

[Effectiveness of arthroscopic synovectomy in rheumatoid arthritis].
Carl, HD, Swoboda, B
Zeitschrift fur Rheumatologie. 2008;(6):485-90
Abstract
Arthroscopic synovectomy in rheumatoid arthritis has proven beneficial in terms of pain relief and joint function, both for upper limb joints (shoulder, elbow, wrist) and the knee. The clinical long-term improvement, such as pain reduction and improved joint mobility, seems more distinct in joints with no or mild joint destruction (early synovectomy) compared to advanced joint damage (late synovectomy). Late-stage elbow arthritis, synovitis of the metacarpophalangeal and proximal interphalangeal joints and the rheumatoid ankle can better be addressed by an open approach. Although a real joint-preserving effect has not been demonstrated, pain reduction and improvement in joint function recommend arthroscopic synovectomy as a substantial treatment option in patients with rheumatoid arthritis.

[Osteonecrosis in the postarthroscopic knee].
Pape, D, Lorbach, O, Anagnostakos, K, Kohn, D
Der Orthopade. 2008;(11):1099-100, 1102-7
Abstract
Osteonecrosis of the knee is a rare complication following arthroscopic surgery. Little is known about its etiology. The most important differential diagnosis is preexisting and undiagnosed early-stage spontaneous osteonecrosis of the knee. Medicolegally, arthroscopic surgery could be wrongly regarded as the primary cause for postarthroscopic osteonecrosis. Orthopedic surgeons need to be aware of the diagnostic pitfalls in differentiating between these entities. We suggest that the descriptive term "osteonecrosis in the postoperative knee" should be used rather than the captious term "postarthroscopic osteonecrosis."

The technique of synoviorthesis.
Rodriguez-Merchan, EC, Goddard, NJ
Haemophilia : the official journal of the World Federation of Hemophilia. 2001;:11-5
Abstract
Synoviorthesis (medical synovectomy) is a commonly utilized procedure employed in the management of recurrent intra-articular bleeds and secondary chronic synovitis in haemophilic patients. The procedure involves the intra-articular administration of an agent in order to induce fibrosis in the inflamed synovium so reducing the bleeding tendency. Such agents may either be chemical based (osmic acid, rifampicin) or radioactive (yttrium, gold or phosphorus). Whichever agent is employed care must be taken to avoid extra-articular complications (radiation burn and/or inflammatory reaction) as a result of extravasation or needle track contamination. The most frequently affected joints in haemophilia are the elbows, knees and the ankles, and to a lesser extent the shoulders and hips. This article outlines the techniques of injection of the five aforementioned joints, with details of the anatomical landmarks to perform the injections correctly. Injection of the elbows, knees and ankles may be carried out simply on an out-patient basis under local anaesthesia. However, it is advisable to perform injection of the shoulder or hip under radiographic control in order to ensure accurate placement. Very young children may require either sedation or a general anaesthetic. Strict asepsis is naturally a paramount requirement.
