About this trial
The goal of this clinical trial is to see if people with knee osteoarthritis would be willing to comply and adhere to incorporating Recombinant Human Growth Hormone (rHGH), specifically Saizen Somatropin solution, into their treatment plan.
Participants will be asked to:
* Self-inject the treatment solution (placebo or somatropin) into the abdominal or gluteal area once per day for a total of 6 weeks. * Complete questionnaires related to their knee pain and activities of daily living. * Provide blood tests. * Complete various measurements including: circumference of thigh, calf, and abdomen; strength of thigh and knee; range of motion of both knees; and gait analysis.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Between 18 - 65 years old.
Diagnosis of isolated knee osteoarthritis for greater than 6 months.
Disqualifiers
Previous or pending major intra-articular or reconstructive surgery to the involved knee, including femoral/tibial osteotomies, ligament repair/reconstruction, or cartilage transplantation. Patients with remote (>1 year) diagnostic arthroscopy, arthroscopic debridement, meniscectomy, or meniscal repair may be allowed to participate at the investigators' discretion.
Previous major trauma (including fracture, dislocation, open injury) to the involved knee, or ipsilateral hip, knee, ankle, or hip. Patients with prior complete ligament tears will be excluded, patients with chronic partial thickness ligament tears or degenerative/complex meniscal tears (>6 months from injury) may be included at the investigators' discretion
Recent (less than 6 months) intra-articular injection into the involved knee.
High grade ligamentous knee injury.

Treatments tested in this trial
Somatropin (recombinant human growth hormone)
DrugStudy participants will deliver Somatropin via self-administered subcutaneous injection into the abdomen or gluteal region once per day for six weeks at a dose of 0.5mg/day per body surface area (0.5mg/m2/day).
bacteriostatic saline placebo
DrugStudy participants will deliver bacteriostatic saline via self-administered subcutaneous injection into the abdomen or gluteal region once per day for six weeks in an identical delivery device to the experimental arm.
Treatment groups
Trial outcomes
Primary outcomes
Feasibility of the medication administration
Participant adheres to self-administration of injections once daily for 6 weeks.
Secondary outcomes
Clinical Outcomes: knee extension strength
Participants' knee extension strength will be measured using HUMAC Norm Extremity Strength Testing system.
Clinical Outcome: knee flexion strength
Participants' knee flexion strength will be measured using HUMAC Norm Extremity Strength Testing system.
Clinical Outcomes: thigh muscle strength
Participants' thigh muscle strength will be measured through hip flexion, hip abduction and knee flexion using a goniometer.
Clinical Outcomes: Kinematic Gait Analysis
Participants' kinematic gait analysis will be measured with single/ two leg hop/jump and single/ two leg squat, using the Theia Markerless system before and after treatment.
