Tissue Integration of Calcium Phosphate Compound after Subchondroplasty: 4-Year Follow-Up in a 76-Year-Old Female Patient.

Subchondroplasty is a new minimally invasive surgical technique developed to treat bone marrow lesions (BML) and early osteoarthritis (OA). During the procedure, engineered calcium phosphate compound (CPC) is injected. It is claimed by the manufacturer that during the healing process, the CPC is replaced with new bone.

Failure to maintain segmental lordosis during TLIF for one-level degenerative spondylolisthesis negatively affects clinical outcome 5 years postoperatively: a prospective cohort of 57 patients.

Purpose: The present study aimed to determine whether obtaining adequate lumbar (LL) or segmental (SL) lordosis during instrumented TLIF for one-level degenerative spondylolisthesis affects midterm clinical outcome.

Methods: The study was designed as a prospective one, including 57 patients who underwent single-level TLIF surgery for degenerative spondylolisthesis. Patients were analyzed globally with additional subgroup analysis according to pelvic incidence (PI).

Effects of a platelet gel on early graft revascularization after anterior cruciate ligament reconstruction: a prospective, randomized, double-blind, clinical trial.

Background: Slow graft healing in bone tunnels and a slow graft ligamentization process after anterior cruciate ligament (ACL) reconstruction are some of the reasons for prolonged rehabilitation.

Aims: The purpose of this study was to determine if the use of platelet gel (PG) accelerates early graft revascularization after ACL reconstruction.

Methods: PG was produced from autologous platelet-rich plasma and applied locally.

Type of archwire and level of acidity: effects on the release of metal ions from orthodontic appliances.

Objective: To examine the effects of three different parameters-pH value, type of archwire, and length of immersion-on release of metal ions from orthodontic appliances.

Materials And Methods: Simulated fixed orthodontic appliances that corresponded to one-half of the maxillary arch were immersed in artificial saliva of different pH values (6.75 +/- 0.
