Brief Summary
Pathological arthritis is a degenerative disease affecting the joints, characterized by pain, limitation of movement up to ankylosis and disability. Treatment is aimed at reducing pain and slowing the loss of functionality of the district. Among conservative treatments, pharmacological options (NSAIDs, cortisone, contrasupplements, hyaluronic acid) and non-pharmacological options (therapeutic exercise, physical therapy, orthosis, etc.) are indicated. In cases not responding to conservative treatments, surgical treatment will be necessary with prosthetic replacement of the joint district.

Outcome Measures
Primary Outcomes (2)
recovery of pain
The visual analog scale (VAS) is a validated, subjective measure for acute and chronic pain. Scores are recorded by making a handwritten mark on a 10-cm line that represents a continuum between "no pain" and "worst pain."
From enrollment to 1, 3 and 6 months
Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)
questionnaire consisting of 24 questions addressing pain, stiffness and physical function. Score from 0 to 96, higher scores correspond to worse clinical condition.
From enrollment to 1, 3 and 6 months
Secondary Outcomes (2)
Roles and Maudsley Score
At 1, 3 and 6 months

From enrollment to 6 months
Study Arms (2)
Exercise Group
ACTIVE COMPARATORonly a daily exercise program for 4 weeks: passive and active assisted movement of the knee joint, hamstring stretching, and quadriceps strengthening exercises
ESWT group
EXPERIMENTALShockwave therapy will be administered using an ESWT device (Minilith SL1, Storz) once a week for three consecutive weeks, for a total of three sessions. A focused shockwave modality with an electromagnetic device was chosen for the therapy.
Interventions
During each session, participants will receive 2000 pulses at a frequency of 4 Hz and an EDF between 0.02 and 0.2 mJ/mm2.
Eligibility Criteria
You may qualify if:
- persistent knee pain for at least 3 months, measured with a VAS scale of 4 or higher,
- clinical and radiological diagnosis confirming knee osteoarthritis grade 2 and 3 based on the Kellgren-Lawrence system,
- no history of physical therapy in the last 3 months,
- no infections, tumors in the treatment area of the knee,
- no pathology other than osteoarthritis that could cause knee pain,
- no pathology of the lumbar spine or hip that could refer knee pain,
- free from any condition that prevents participation in exercise or physical therapy willing to participate regularly in the treatment programs were included in the study.
You may not qualify if:
- inability to walk,
- a history of clinically symptomatic spinal stenosis or lumbar radiculopathy,
- evidence of a neurological disorder based on history or physical examination,
- generalized pain or fibromyalgia,
- secondary osteoarthritis (to metabolic or rheumatologic disease),
- administration of intra-articular injections (anesthetic, hyaluronic acid, cortisone) of the knee in the last 6 months,
- use of NSAIDs, paracetamol or topical agents in the previous week,
- a previous history of surgery involving the knee joint,
- contraindications to physical therapy (PM, epilepsy, neoplasia, coagulopathy, pregnancy).
