CLINICAL AND ANTHROPOMETRIC CHARACTERISTICS OF PATIENTS AFTER MENISCECTOMY AND THEIR IMPACT ON EARLY POSTOPERATIVE FUNCTIONAL STATUS
Keywords:
meniscectomy, knee joint, pain, quadriceps strength, cartilage tissue, medical rehabilitation.Abstract
This article presents the results of a study aimed at determining the relationships between clinical, functional, and morphological
parameters in patients after meniscectomy, with the aim of substantiating personalized approaches to medical rehabilitation. The study included 132 patients aged 18 to 60 years who had undergone partial or complete meniscectomy. Pain was assessed using a visual analog scale (VAS), quadriceps strength using a handheld dynamometer, knee range of motion (goniometry), and functional status using the Lysholm scale. Thirty-two patients additionally underwent MRI to analyze the condition of articular
cartilage. Statistical processing included correlation analysis (significance level p < 0.05). It was found that patients after meniscectomy had significantly higher pain levels (4.8 ± 1.2 versus 0.8 ± 0.6 points; p < 0.01), decreased quadriceps strength (−24.5% of normal), decreased range of motion (118.6 ± 8.3° versus 135.4 ± 4.7°; p < 0.01) and worsening functional indicators
according to the Lysholm scale (78.4 ± 6.5 versus 95.2 ± 3.1; p < 0.01). Significant correlations were found between pain level and quadriceps strength ( r = -0.62), cartilage condition and muscle activity ( r = 0.55), and between pain and cartilage tissue condition ( r = -0.58; p < 0.01). It was concluded that the condition of patients after meniscectomy is determined by the combined influence of pain syndrome, muscle failure, and morphological changes in articular cartilage. The main determinants of rehabilitation
effectiveness are quadriceps strength, pain level, and the structural condition of cartilage tissue.
