BACKGROUND: Many factors affect recovery from arthroscopic partial meniscectomy, including patient sex. However, sex differences in time to maximal recovery of knee function and factors influencing differential rates of recovery are unknown. QUESTIONS/PURPOSES: We determined (1) preoperative sex differences, (2) sex differences in rate and extent of recovery through 1 year postoperatively, and (3) clinical and fitness variables that could explain potential sex differences in recovery from partial meniscectomy.

BACKGROUND: The experience of undergoing surgery is known to induce a short-term, fight-or-flight physiological stress response. As an optimum immune response at the site of surgery would enhance tissue repair, we examined surgical stress-induced immune cell redistribution profiles as predictors, and potential mediators, of short and long-term postoperative recovery. We tested the a priori hypothesis that predefined adaptive immune cell redistribution profiles observed during surgery will predict enhanced postoperative recovery.

Fibrochondrocytes of meniscus adapt to changes in their biomechanical environment by mechanisms that are yet to be elucidated. In this study, the mechanoresponsiveness of fibrochondrocytes under normal and inflammatory conditions was investigated. Fibrochondrocytes from rat meniscus were exposed to dynamic tensile forces (DTF) at various magnitudes and frequencies. The mechanoresponsiveness was assessed by examining the expression of inducible nitric oxide synthase (iNOS), tumor necrosis factor-alpha (TNF-alpha), and matrix metalloproteinase-13 mRNA expression.

OBJECTIVE: To present the first reported case of successful chiropractic intervention in treatment of a torn medial meniscus of the knee, the meniscal tear being documented by magnetic resonance imaging (MRI). CLINICAL FEATURES: A 54-yr-old woman complaining of right knee pain of several months' duration with accompanying marked functional impairment was diagnosed as having a tear in the posterior horn of the ipsilateral medial meniscus, verified by MRI studies of the same.

OBJECTIVE: To describe the chiropractic management of a patient suffering from a right lateral meniscus tear concurrent with calcium pyrophosphate dihydrate (CPPD) deposition disease. CLINICAL FEATURES: A 51-yr-old bus driver suffered from right knee pain (7 on a 1-10 pain scale). The onset of the pain was gradual and increased during braking and accelerating. Palpatory tenderness was noted at the right lateral knee joint line and the inferior lateral margin of the patella.
