Common Joint Injuries

Common Joint Injuries: Knee and Shoulder Joint injuries, particularly in the knee and shoulder, are prevalent among both athletes and the general population. Understanding the principles of examination, investigation, and management is essential for accurate diagnosis and effective treatment. Knee Injuries Anterior Cruciate Ligament (ACL) Injury:      Mechanism: Often occurs during sports that involve sudden stops, changes in direction, or direct trauma to the knee. Clinical Presentation: Immediate pain and swelling, instability (feeling of giving way), and difficulty bearing weight. Examination: Lachman test and anterior drawer test for laxity, pivot shift test for ACL integrity. Investigations: MRI to confirm ACL tear and assess for associated injuries (e.g., meniscal tears, collateral ligament injury). Management: o Conservative: RICE (Rest, Ice, Compression, Elevation), physical therapy for strengthening and proprioception. o Surgical: ACL reconstruction for active individuals or those with concurrent injuries affecting knee stability. Meniscus Tears:    Mechanism: Twisting or pivoting motions, common in sports or activities that involve sudden changes in direction. Clinical Presentation: Pain along the joint line, swelling, locking or catching sensation, decreased range of motion. Examination: McMurray test and Thessaly test for meniscal tear, joint line tenderness.   Investigations: MRI to confirm tear and determine tear type (e.g., medial or lateral, location). Management: o Conservative: RICE, physical therapy for range of motion and strengthening. o Surgical: Partial meniscectomy for symptomatic tears, meniscus repair for select cases (e.g., younger patients with peripheral tears). Patellofemoral Pain Syndrome (Runner's Knee):      Mechanism: Overuse, poor biomechanics (e.g., abnormal patellar tracking), or muscle imbalance. Clinical Presentation: Anterior knee pain exacerbated by activities like running, stairs, or prolonged sitting. Examination: Patellar grind test, evaluation of patellar alignment and tracking. Investigations: X-ray or MRI to rule out structural abnormalities (e.g., patellar maltracking, chondromalacia). Management: o Conservative: Activity modification, physical therapy focusing on quadriceps and hip muscles strengthening, patellar taping or bracing. o Surgical: Rarely indicated; may include realignment procedures in refractory cases. Shoulder Injuries Rotator Cuff Tears:      Mechanism: Degenerative changes, repetitive overhead activities, or acute trauma. Clinical Presentation: Shoulder pain (especially with overhead activities), weakness, and decreased range of motion. Examination: Empty can test (Jobe test), drop arm test, palpation for tenderness and muscle atrophy. Investigations: MRI to confirm tear size, location, and integrity of other rotator cuff tendons. Management: o Conservative: RICE, physical therapy for range of motion and strengthening (focus on rotator cuff muscles). o Surgical: Arthroscopic repair for symptomatic tears or in younger patients with significant functional impairment. Shoulder Dislocation/Subluxation:      Mechanism: Traumatic injury or congenital laxity, commonly anterior dislocation. Clinical Presentation: Acute onset of severe shoulder pain, visible deformity, limited range of motion. Examination: Provocative tests (e.g., apprehension test, relocation test), assessment of neurovascular status. Investigations: X-ray to confirm dislocation and assess for associated fractures (e.g., Hill-Sachs lesion, Bankart lesion). Management: o Reduction: Closed reduction under sedation or anesthesia. o Rehabilitation: Physical therapy for shoulder strengthening and stability exercises. o Surgical: Bankart repair for recurrent instability or in young, active patients. Principles of Examination, Investigation, and Management      History and Physical Examination: Thorough assessment of mechanism of injury, onset of symptoms, exacerbating factors, and detailed joint examination including range of motion, stability tests, and provocative maneuvers. Imaging Studies: Utilize appropriate imaging modalities (X-ray, MRI, CT) to confirm diagnosis, assess injury severity, and guide treatment decisions. Conservative Management: Initial treatment with RICE protocol, pain management, and physical therapy to restore function and prevent recurrence. Surgical Intervention: Consider surgical options for refractory cases, significant functional impairment, or in young, active individuals aiming to return to highdemand activities. Rehabilitation and Follow-up: Tailor rehabilitation programs to specific injury patterns, focusing on restoring strength, range of motion, proprioception, and functional activities. Ensure close follow-up to monitor progress and adjust treatment as necessary. Understanding these principles allows healthcare providers to effectively manage knee and shoulder joint injuries, optimize recovery outcomes, and facilitate return to activities of daily living or sports participation. Early recognition, accurate diagnosis, and timely intervention are critical in achieving favorable patient outcomes and preventing long-term complications.
