Prospective Evaluation of Clinical Outcomes of the Subchondroplasty Procedure for Treatment of Symptomatic Bone Marrow Lesions of the Knee.

Bone marrow lesions (BMLs) have a strong correlation to patient-reported pain, functional limitations, joint deterioration, and rapid progression to total knee arthroplasty. The Subchondroplasty (SCP) procedure uses AccuFill, a calcium phosphate bone substitute material (BSM), to treat bone defects such as microtrabecular fractures and BML. This observational, prospective, multicenter, cohort study evaluated the effect of the SCP procedure at the 2-year follow-up for 70 patients with knee BML.

Favorable Reoperation Rate at 2 Years Following Repair of Horizontal Cleavage Tears Using an All Suture-Based Technique: A Prospective, Multicenter Trial.

Purpose: This prospective, multicenter trial evaluates the clinical success (as measured by reoperation rates and improvements in patient-reported outcome measures) of using circumferential compression stitches with all-suture techniques for horizontal cleavage tears (HCTs) of the meniscus.

Methods: Investigators enrolled 30 patients (mean age, 38.2 years; standard deviation, 11.

High stiffness of human digital flexor tendons is suited for precise finger positional control.

The objective of this study was to define the biomechanical properties of the human digital flexor tendons and to compare these biomechanical properties to other muscle-tendon units in the forearm. Mechanical measurements were performed on fresh-frozen tendons under physiological load and temperature conditions. Loads were determined by first measuring the physiological cross-sectional area of each digital belly of the flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) and estimating maximum tension (P(o)) of that specific muscle head.

Arthroscopic assessment of occult intra-articular injury in acute ankle fractures.

Purpose: To arthroscopically assess the pattern and extent of intra-articular damage associated with ankle fractures.

Type Of Study: Prospective case series.

Methods: From 1989 to 1998, 48 consecutive patients with acute unstable ankle fractures underwent ankle arthroscopy followed by reduction and internal fixation.
