Introduction

Joint stiffness is a condition characterized by reduced range of motion (ROM), pain, and discomfort during movement. It can be caused by acute injuries, chronic inflammatory conditions, or degenerative diseases such as osteoarthritis and rheumatoid arthritis. Stiffness is the outcome of complex physiological processes that include trauma, inflammation, and tissue repair, which occur in a sequence of stages: bleeding, edema, granulation tissue formation, and fibrosis. Each stage has its own pathological characteristics and clinical implications. Early recognition coupled with targeted management at all stages is important to be able to restore joint functions and prevent long-term consequences.

Stages of Joint Stiffness

Bleeding Stage

Pathology: The bleeding stage starts immediately after a joint injury or trauma. Trauma to the blood vessels leads to bleeding into the joint cavity (hemarthrosis) or surrounding soft tissues. The presence of blood triggers an inflammatory response that initiates the repair process but also causes stiffness.

Signs and Symptoms:

• Acute pain localized to the injured joint
• Rapid onset swelling within hours
• Warmth and tenderness
• Visible bruising or discoloration
• Restricted ROM due to swelling and discomfort

Assessment:

1. Clinical Examination: Look for swelling, discoloration, and warmth. Check for tenderness by palpation.
2. Imaging: MRI or ultrasound can be done to confirm hemarthrosis and the amount of bleeding that has occurred .
3. Blood Tests: Clotting profiles may be checked if the bleeding is recurrent.

Management:

• Physiotherapy: Rest and immobilization decrease further bleeding. Cryotherapy or ice packs applied to the area for 15–20 minutes, 3–4 times a day, reduces inflammation. Compression wraps decrease swelling.
• Medical: If hemarthrosis is severe, joint aspiration is performed to remove accumulated blood. Nonsteroidal anti-inflammatory drugs (NSAIDs) help manage pain and inflammation .

Edema Stage

Pathology:

Edema occurs as an inflammatory response following the bleeding stage. Inflammatory mediators, such as histamine and prostaglandins, increase vascular permeability, leading to fluid accumulation in the interstitial spaces.

Signs and Symptoms:

• Persistent swelling around the joint
• Mild to moderate pain that worsens with movement
• Joint warmth without associated discoloration
• Perception of tightness or fullness in the joint

Assessment:

1. Circumferential Measurement: Monitor swelling at specific anatomical landmarks using a tape measure.
2. Functional Testing: Goniometry measures the joint's range of motion.
3. Ultrasonography: Identifies fluid collections within the joint space or soft tissues.

Management:

• Physiotherapy: Lymphatic drainage massage facilitates reabsorption of fluid. Active-assisted ROM exercises are performed to avoid stiffness. Modalities such as ultrasound therapy or TENS assist in pain and inflammation management.
• Medical: NSAIDs are continued for the control of inflammation. If edema does not resolve, then corticosteroids can be administered in severe cases .

Granulation Tissue Formation Stage

Pathology:

Granulation tissue, containing fibroblasts, capillaries, and inflammatory cells, forms as a natural process of healing. Although it assists in the restoration of injured structures, increased proliferation creates adhesions and stiffness of the joint.

Signs and Symptoms:

• Stiffness at the start of the day that improves with activity
• Pain when the joints are moved through their extreme ranges
• Decreased, smooth movement as a result of tissue binding
• Minimal swelling of the joint

Assessment:

1. Palpation: Look for regions of thickened tissue or fibrosis.
2. ROM Testing: Limitation in movement is noted, particularly flexion and extension.
3. Arthroscopy: It is done directly to visualize if the stiffness persists.

Management

• Physiotherapy Management: Manual Therapy including mobilization of joint and soft tissue manipulation facilitates an improvement in ROM. Stretching using gentle progressive exercises decrease adhesions. Hydrotherapy - Buoyancy in water enables easy movement with lesser joint loading.
• Medical Management: Corticosteroid injection helps reduce inflammation, making physiotherapy progress smooth.

Fibrosis Stage

Pathology: If inflammation and tissue repair persist or do not resolve, fibrosis results. Overproduction of collagen produces thick, nonpliable scar tissue that permanently can limit joint mobility. Advanced stages of fibrosis may even cause contractures or deformities.

Symptoms and Signs:

• Chronic, constant stiffness that is worse when inactive
• Pain about the joint, particularly during attempts to stretch or load
• Visible deformities if advanced
• Tissue feel hard and immobile in palpation around the joint

Assessment:

• Imaging: MRI shows tissue as fibrotic with adhesions.
• Functional Testing: Thorough assessment of ROM and muscle strength.
• Clinical Grading: Rate contractures according to degree and functional impairment.

Management:

• Physiotherapy: Intensive ROM exercises and strengthening interventions reverse stiffness. Myofascial release and instrument-assisted soft tissue mobilization address fibrotic tissue. Functional training restores ADLs.
• Medical: Surgical Interventions: Arthroscopic or open capsular release for severe fibrosis. Pharmacotherapy: Maintaining NSAIDs or biologic agents for the inflammatory conditions .
