Three-dimensional Imaging and Computer Navigation in Planning for Hip Preservation Surgery
Hip preservation surgery is performed to address femoroacetabular impingement, alleviate any associated pain, and reduce the risk of early onset of osteoarthritis. In the last decade, arthroscopy has become more popular in addressing femoroacetabular impingement, due to its minimally invasive approach. However, poor visualization and limited spatial awareness of the joint make arthroscopy of the hip difficult, resulting in a steep learning curve. This paper reviews the utility and benefits of 3-dimensional imaging and computer navigation and what these tools may add to the preoperative planning stages of hip preservation s...

Clinical Application of Scaffolds for Partial Meniscus Replacement
Meniscal tears are common injuries often treated by partial meniscectomy. This may result in altered joint contact mechanics which in turn may lead to worsening symptoms and an increased risk of osteoarthritis. Meniscal scaffolds have been proposed as a treatment option aimed at reducing symptoms while also potentially reducing progression of degenerative change. There are 2 scaffolds available for clinical use at the present time; Collagen Meniscus Implant and Actifit. Medium-term to long-term data (4.9 to 11.3 y) demonstrate efficacy of partial meniscus replacement. The patients who seem to benefit most are chronic postm...

Complications of Biodegradable Materials: Anchors and Interference Screws
Metal, plastic, and biodegradable implants can all cause problems. The advantage of the biodegradable implant is clarity in postoperative imaging, easier revision, and fewer concerns about associated tissue damage. Although biodegradable implants do degrade over time, this time varies considerably, depends upon the polymer present, and is often measured in years. Before that occurring, the implant is a rigid device. Problems in the operative or immediate postoperative period include implant breakage during insertion, loss of initial fixation, incompletely buried or “proud” implants within a joint that could damage arti...

BioCartilage: A New Biomaterial to Treat Chondral Lesions
Articular cartilage damage affects almost everyone at some point. Our ability to heal these defects has been very limited. Microfracture, which is one of the most common attempted surgeries for chondral lesions, has resulted in poor long-term outcomes. Other solutions like allograft osteochondral autograft transfer system, DeNovo, or autologous chondrocyte implantation are more extensive, difficult, expensive surgeries, and are better served for larger lesions. Smaller lesions have shown good short-term outcomes with microfracture but result in creation of fibrocartilage, which is weaker and softer and does not hold up lon...

Massive Irreparable Rotator Cuff Tears: A Solution That Bridges the Gap
The successful treatment of symptomatic chronic, massive irreparable rotator cuff tears remains a difficult problem for many shoulder surgeons. Multiple procedures have been attempted to address this problem including latissimus dorsi transfer, arthroscopic shoulder debridement, and reverse total shoulder arthroplasty. Not every patient is a candidate for the above procedures and those that do undergo one of the above procedures has no guarantee of experiencing clinical improvement. Therefore, many shoulder surgeons have looked toward additional methods to manage the chronic, massive irreparable rotator cuff tear. Acellula...

DeNovo NT Particulated Juvenile Cartilage Implant
Biological repair of focal chondral defects represents a significant clinical challenge as cartilage lacks intrinsic healing ability. Although it can be difficult to measure the objective success of cartilage repair techniques, the primary objective is symptom relief leading to less pain and improved function for the patient. Likely, the most important key to success is proper clinical indications. Second to this, the type of cartilage treatment utilized should be based on lesion location, size, depth, and other patient factors. One such treatment is DeNovo Natural Tissue. This method relies on the ability of juvenile chon...

Autologous Chondrocyte Implantation With Collagen Membrane
The first-generation autologous chondrocyte implantation (ACI-P) described by Peterson and colleagues used a periosteal patch to form a watertight cover over the articular cartilage defect, under which the autologous chondrocyte suspension was injected. Although good to excellent outcomes were often seen in >80% of patients and the durability of the repair documented up to 20 years, the procedure was noted to have a high rate of subsequent surgical procedures, most often for arthroscopic debridement of periosteal hypertrophy or incomplete incorporation. Consequently, the surgical technique advanced to use a porcine-derived...

Biodegradable Materials: Anchors and Interference Screws
Biodegradable implants allow clarity in postoperative imaging, easier revision, and fewer concerns about associated tissue damage. It is important to appreciate that different biodegradable materials have different properties and different degradation rates. Faster degradation can be associated with a greater inflammatory response. However, inflammation is a normal part of the degradation process. The concern arises when the inflammation is clinically significant. (Source: Sports Medicine and Arthroscopy Review)
