CPM Machine for Knee Replacement Recovery, Continuous Passive Motion, 30°-110° Flexion

We ship within 5 business days of placing your order. Tracking is emailed as soon as it leaves our California facility. If you need the machine by a specific surgery or discharge date, order at least a week ahead or email sales@scimedstore.com and we will confirm timing.

Rental through a DME supplier is often covered by insurance for a short post-op window (commonly around 21 days). Buying makes sense when rental is not covered, when your surgeon wants a longer CPM program, when both knees will be replaced at different times, or for clinics and rental companies that use the unit for many patients. Always follow your surgeon's CPM protocol.

CPM machines for post-TKA use are typically covered under Medicare DME benefit (HCPCS codes E0935 for rental, E0936 for purchase) for a defined post-op period (usually 21 days). Individual coverage varies by insurance plan and medical necessity documentation. For DME rental companies: this unit qualifies for standard DME rental billing. For individual patient purchase: verify with your insurance before buying, you may qualify for rental coverage instead.

Feature-for-feature, largely the same clinical function, continuous passive motion 30°-110°, patient safety switch, quiet motor, bed-mountable, 3-year warranty. Kinetec Spectra has slightly wider flexion range (-10° to 120° vs our 30°-110°), more precise servo motor (vs our continuous-duty gear), and a slightly quieter operation (<40 dB vs 40-50 dB). Price differential: $1,999 vs $6,500-$8,500. For 95% of post-TKA and ACL rehab protocols, the SciMed unit's 30°-110° range is fully sufficient (most protocols target 90-110° flexion recovery). Kinetec's extended range benefits only high-flexion Asian squatting protocols and advanced athletes.

Standard post-TKA and ACL protocols target 90-110° flexion recovery by 4-6 weeks post-op, well within our range. If your surgeon's protocol targets 120°+ flexion (rare, typical for very active patients and Asian squat cultures), this unit may not reach full protocol target. However, once patient hits 100°+ flexion in CPM, they typically transition to active PT and gravity-assisted flexion (heel slides, wall slides), not continued CPM. The 30°-110° range covers the entire CPM phase of standard protocols.

Yes, designed for home use post-discharge. Patient safety switch allows immediate motion stop. Operation is simple (set flexion target, press start, patient controls stop). Home health agency, PT clinic staff typically set up the unit and educate patient/family on operation. For home rental: expect a home health visit for initial setup and teaching in the first 24 hours after hospital discharge.

40-50 dB during operation, comparable to a quiet refrigerator or soft conversation. Not silent, but not disruptive to sleep. For hospital ward use with multiple CPM machines running simultaneously, cumulative noise is manageable. For home use in the same bedroom as the patient, most patients acclimate within 1-2 nights. If noise is a critical concern (light sleeper and shared bedroom), the Kinetec Spectra at <40 dB may be quieter, but the cost differential is significant.

Adjustable thigh length accommodates adult and adolescent patients (typical fit for age 12+). For pediatric CPM (age 6-12), the thigh length adjustment may not shorten enough. For infants and toddlers with congenital knee issues, this unit is not appropriate, pediatric CPM is a specialty category. Contact us if you need pediatric CPM options.

Typical DME rental service life: 5-7 years with 4-6 rental cycles per year (each cycle 4-8 weeks patient use). Total lifetime cycles: 20-40 patient rentals per unit. Motor and gear system is the primary wear component (typically survives 15,000-25,000 hours of use); foam padding and patient hand-switch may need annual replacement in high-volume rental fleets. Spare parts stocked in San Jose for 5+ years post-purchase.

3-year full manufacturer warranty on motor, frame, controls, safety switch. Covers manufacturing defects and normal use wear. Cosmetic damage, damage from patient / operator misuse, and consumables (foam pads, hand-switch cable) not covered after 90 days. Extended 5-year service contract available for DME rental fleet operators (+$300/unit at time of order).

Specify 110V (US standard) or 220V (international) at order. US hospitals, DME and home rental all standard 110V. International orthopedic centers typically 220V. Universal 100-240V configuration available for facilities with mixed power infrastructure (+$100).

US: FedEx / UPS Ground insured, ~15 kg boxed. International: DHL Express DDP for single-unit urgent (~$200-400 depending on country) or ocean freight DDP for 5+ unit orders (cheaper per unit). Ships to India, LATAM (Mexico/Brazil/Colombia), MENA (UAE/Saudi/Egypt), SE Asia (Vietnam/Indonesia/Philippines/Malaysia), Sub-Saharan Africa (Kenya/Nigeria/South Africa), GCC, UK, EU, AU/NZ. Post-op orthopedic rehab is a major growth market in emerging economies where TKA volume is climbing rapidly.
